2.4.2. Audiosystem The design of the control panel of audiosystem of Bose regularly established on Infiniti cars is shown below.
Control panel of an audiosystem of a standard complete set of Bose
Features of functioning of system in a radio reception mode
General information
Functioning of a radio receiver possibly only in the positions ON and ASS of the lock of ignition.
Purity of reproduction is influenced by such factors, as signal capacity, removal from the next repeater, presence nearby bridge farms, high-rise buildings and other sources of passive hindrances.
The most typical source of active hindrances is the mobile phone which use in salon of the car can make essential impact on quality of radio reception.
It is necessary to pay attention of the reader also to that fact that some physical features of distribution of radio-waves (both frequency, and peak modulation), are capable to influence purity of their reception in a moving vehicle irrespective of the fact of existence of hindrances and level of used equipment.
Remember that the moving car is far not ideal object for reception of radio-waves. Owing to moving of a condition of reception continuously change. From time to time in close proximity there are large structures and the heights, making negative impact on distribution of electromagnetic radiation — even moving in the neighbourhood or towards a vehicle can influence quality of reception.
Features of distribution of radio-waves of an ultrashort range (FM)
|
|
When using radio receiver in FM range limiting removal from the next repeater is the distance of 40 — 48 km. |
In a monophonic mode range of reception can increase a little in comparison with a stereofoniya. Presence of sources of passive and active hindrances can influence quality of radio reception even within a 40-kilometer zone. The capacity of frequency modulated (FM) of a signal mainly is defined by removal from a source a principle of distribution of ultra-short waves is similar to a principle of distribution of light, so, for example, they possess ability to be reflected from various objects.
Attenuation and shift of bearing frequency: In process of car removal from a source of radiation of radio-waves the signal tends to attenuation and shift of bearing frequency.
Static hindrances: As a result of rendered by large objects (buildings, hills, etc.) influences at reception of radio signals can arise the high-frequency hindrances which intensity can be lowered by a way of twisting of level of reproduction of high frequencies (TREBLE).
Cross hindrances: In view of ability of ultrashort radio-waves to reflection in some situations there can be overlays of signals from various radio stations that leads to interruptions in reception and sporadic losses of a sound.
Features of distribution of the average, long and short radio-waves applied in a range (AM)
Such radio-waves possess ability not to be reflected (to get through their distributions meeting on a way objects) but to be reflected from Earth ionosphere. Told means that these signals are also subject to an interference on a way from a source to the receiver.
Attenuation: Reception attenuation in a low-frequency range can arise at car movement under overpasses and road outcomes, and also among high-rise buildings, besides, short decrease in level of reception can be caused by turbulent indignations of an ionosphere even in the flat district.
The most typical example of the static hindrances, making essential impact on purity of radio reception in a range of AM lightning discharges, and also high-voltage power lines and even svetoforny objects are.
Audiosystem use
Features of some constructive decisions
Signal reception in VHF a range is often accompanied by the strong noise connected with good reflection of ultra-short waves from various obstacles. The system of double reception based on two aerials is applied to improvement of quality of reception. The first aerial represents the ordinary telescopic aerial. The second aerial — wire type — is pasted on back glass of the car. The system is automatically switched to that aerial which provides at present the best quality of reception.
In a recorder prefix the head from a nikelezhelezny alloy (permally), providing high purity of reproduction in a range of high frequencies is applied. Decrease in noise level it is provided also at the expense of application of system of a shumopodavleniye of Dolby NR — filters of the Dolby NR brand are made according to the Dolby corporation license, the inscription of Dolby NR and a symbol in the form of double D are trademarks of this corporation. The contour of automatic adjustment of intensity of sounding provides additional improvement of quality of reproduction in a range of low frequencies both in a radio reception mode, and when listening magnetic and laser recording.
Inclusion sounding food / volume control
Turn the ignition key in the situation ON or ASS, then press the ON-OFF/VOL button at the left on audiosystem control panels (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) — the system will automatically pass to that mode of reproduction (radio receiver / tape recorder / CD player) in which it was disconnected (if the cartridge or a compact disc are not loaded into the corresponding loader, the radio reception mode is activated). The repeated pressing the button leads to system shutdown.
Volume control of sounding is made by ON-OFF/VOL handle rotation.
Adjustment of a timbre of sounding and balance of a sound
Balancing of distribution of a sound and adjustment of a timbre of sounding
Switching of modes of adjustment BASS (basses), TRE (high frequencies), (balance between lobbies and back loudspeakers) and BAL (balance between the right and left loudspeakers) is made by FAD by means of the AUDIO button on the right on the audiosystem control panel (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) — on the screen of the display will be highlighted an inscription of the corresponding contents.
Order of switching of modes — see an illustration Balancing of distribution of a sound and adjustment of a timbre of sounding. Actually adjustment, after a choice of a demanded mode, is carried out by means of two buttons and.
10 seconds later the system will automatically return to a usual mode of reproduction (radio / tape recorder / CD player). Compulsory return to a reproduction mode after implementation of necessary adjustments can be made by a nazhimaniye way on the AUDIO button demanded quantity of times.
Ruled system uses in a radio reception mode
Range choice
Switching of a frequency range (FM1/FM2/AM) is made by means of the FM/AM button on the audiosystem control panel (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) — at a nazhimaniye to this button at the included ignition (or ASS) the radio receiver will automatically pass ON to reproduction of that radio station on which frequency it was switched off.
|
|
Besides to result will give pressing the ON-OFF/VOL button if in the corresponding loaders there is no cartridge or a compact disc. |
At a nazhimaniye on the FM/AM button during playing of magnetic or laser recording this reproduction will automatically interrupt and the system will pass to a radio receiver mode on frequency of the last chosen radio station.
The highlighting on the screen of the display of a ST symbol means that reception is conducted in a stereophonic mode — at decrease in signal strength the system is automatically switched in monophonic reception.
Mode of manual control
Manual control of frequency of radio reception is carried out by means of buttons and on the right on the audiosystem control panel (see an illustration the Control panel of an audiosystem of a standard complete set of Bose). The pressing of buttons changes frequency of an accepted signal to one step up or down. For fast viewing of frequencies hold the corresponding button pressed during more than 0.5 seconds.
|
|
Control of a radio receiver should not be made by the driver during movement! |
Search / viewing mode
Search (SEEK)
The short-term nazhimaniye on one of buttons of the SEEK/SCAN switch or at the left on the audiosystem control panel (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) leads to inclusion of a mode of automatic search of active radio stations. Viewing of frequencies is made as their increase or reduction depending on what of buttons was pressed. At detection of active frequency search stops and the system passes to a broadcasting mode — in case of need press the corresponding button once again.
Viewing (SCAN)
Keeping of any of mentioned above buttons pressed within more than 1.5 seconds leads to activation browse mode of a range of radio frequencies (see above). In this mode the system automatically looks through all range of frequencies of the tuner, doing 10-second demonstration stops on each of active channels. The exit from browse mode with a stop on the chosen frequency is made by repeated pressing of the same button.
Function of storing of radio stations
Control of a radio receiver for favourite radio stations
The radio receiver allows to fix on six radio stations in each of ranges of frequencies (FM1/FM2/AM).

- Press and hold pressed before reproduction of a short sound signal any of six buttons of a storing / choice of favourite radio stations in the lower part of the control panel of an audiosystem (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) — at a nazhimaniye on the button reproduction should stop.
- After completion of process of storing on the screen of the display the indicator of the respective canal (for example, by ch2 — see an illustration
Control of a radio receiver for favourite radio stations) is deduced, and reproduction renews.
- Installation of the remained six channels is made in a similar manner.
|
|
At shutdown of a food of a radio receiver or safety lock knocking-out memory of a radio receiver is erased. In this case it is necessary to repeat procedure of control for favourite radio stations.
Ruled system uses in a mode of reproduction of magnetic recording
Establish the ignition key in the situation "ASS" or "ON" and horizontally fill the cartridge in a kassetopriyemnik — the cartridge will automatically be involved in a nest by the loader.
|
|
It is not necessary to apply force when filling cartridge! Right after loading of a tape record reproduction will begin — if till cartridge loading the system worked in a mode of broadcasting or playing of laser records, mode change also will occur automatically. |
If to make system shutdown by pressing the ON-OFF/VOL button and not to take the cartridge from a kassetopriyemnik, at repeated inclusion of a food reproduction of the interrupted record from a magnetic tape will proceed.
Activation of reproduction of magnetic recording (TAPE)
The pressing the TAPE button (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) at the loaded cartridge and the switched-off system leads to activation of a mode of reproduction of magnetic recording.
The pressing the TAPE button at the loaded cartridge at the activated mode of broadcasting or reproduction of laser records will give to automatic switchings of a mode and to the beginning of reproduction of magnetic recording.
By means of the same button it is possible to pass to a mode of normal reproduction from modes of the accelerated scrolling (FF/REW) and automatic search (APS FF/APS REW).
Function of accelerated forward (FF) and returnable (REW) of rewind of a film
Activation of a mode of the accelerated rewind of a film in the corresponding direction is made by pressing the button or audiosystem control panels — in the right sector of the screen of the display the corresponding pictogram will be highlighted. For return to a mode of normal reproduction press a touch the button once again, or use the TAPE button (see above).
Function of search of the beginning of records (APS)
The APS function allows to pass automatically by the beginning of records.
At a nazhimaniye on the button (APS FF) during reproduction there is a transition by the beginning of the next record on a magnetic tape. For the admission of several records press the APS FF button demanded quantity of times (admission possibility to 9 records is allowed).
The single pressing the button (APS REW) allows to pass to repetition of reproduction of the current record. Repeated pressing the button carry out transition by the beginnings of higher records.
At APS mode activation in the right sector of the screen the inscription of the corresponding contents (by FF or REW) is highlighted.
For an exit from a mode of search and return to a mode of normal reproduction press a touch the button once again, or use the TAPE button (see above).
The APS function can not work in the following cases:
- Level of record is too low;
- On a tape informal conversation is written down;
- Intervals between records make less than 4 seconds;
- Pauses between records the too long;
- Record goes without intervals;
- The pause is filled with a strong noise background.
Change of the direction of scrolling of a tape (PROG)
The pressing the PROG button leads to switching of the direction of scrolling of a magnetic tape.
|
|
Automatic switchings of the direction of rotation tapes (automatic reversion) occurs at its end. |
By pressing the PROG button in a mode of the accelerated rewind of FF or REW there is a return to a mode of normal reproduction.
System of suppression of noise of Dolby NR
If magnetic recording is coded on Dolby NR system, for elimination of high-frequency noise of a tape press the DOLBY NR button — on the screen of the display the corresponding symbol will be highlighted.

|
Filters of the Dolby NR brand are produced according to the Dolby corporation license. An inscription of Dolby NR and double D are trademarks of this corporation. |
Use of the metallized and chromeplated tapes
When using the cartridge of the Metal or Chrome type the system is automatically switched in a mode of the increased quality of reproduction.
Cartridge extraction
Press the button of emission of the cartridge — reproduction of magnetic recording stops, and the cartridge jumps out from a kassetopriyemnik with simultaneous shutdown of giving of a food.
When playing cartridges with the metallized or chromeplated tape the player automatically is switched to a mode of high-quality reproduction. During playing of such tapes the corresponding indicator burns.
Precautionary measures when using a cassette player
- To keep high quality of sounding use cartridges with duration of reproduction less than 60 minutes.
- It is not necessary to leave the cartridge in a player. Store cartridges in protective covers and do not allow hit on them direct sunlight, heat, moisture and magnetic materials.
- When heating from solar radiation the cartridge can be deformed and become unsuitable for use.
- Do not use the cartridge with lagging behind stickers which can get stuck in a player.
- If the tape in the cartridge was weakened, insert a pencil into one of peremotochny naves and densely reel up a tape on the cartridge roller. The weakened tape can hesitate that will worsen quality of its sounding.
- Eventually reading out, tightening and capstans become soiled fragments of a magnetic layer of a passable tape. Such polluting stratification leads to easing and reproduction distortion in view of what heads should be cleared periodically by means of the special cartridge.
Ruled system uses in a CD player mode
Turn a key in the situation ON or ASS and fill a compact disc in a loading crack of the disk drive with the title party up — the disk should be involved automatically by the loader and start to be lost.
Right after disk loading on the screen of the display the quantity of the paths written down on it and reproduction time is deduced.
If at the moment of loading the audiosystem worked in a mode of broadcasting or reproduction of magnetic recording, change of a mode will occur also automatically.

If at the moment of pressing the button the system worked in a mode of playing of laser records from a disk filled in the disk drive of a player, the current reproduction will stop and the system will be switched in a changer mode. At opposite entering data fairly the return.
If the disk is filled only in the player disk drive, and the loader of a changer is empty, the pressing the CD/CHG button at the switched-off food of system will lead to player activation. If at the moment of pressing the button the player worked, reproduction will stop, and on the display screen in a flashing mode NO DISC message will be deduced. After a while the system will return again to reproduction of the interrupted record from the player of a disk loaded into the disk drive (NO DISC message from the screen will disappear).
If by pressing the CD/CHG button at the switched-off food the changer loader is filled only, there will be an activation of the last.
The pressing the CD/CHG button at empty loaders as player, and changer leads to a conclusion in a flashing mode on the screen of the display of the message of NO DISC.
If at the moment of pressing the button at the loaded player and/or a changer the system worked in a mode of broadcasting or reproduction of magnetic recording, there will be a change of a mode and reproduction of laser records will begin with player or changer disks.
Function of the accelerated scrolling in forward (FF) or the returnable direction (REW)
The pressing the button or control panels of an audiosystem will bring to reproduction of records with the accelerated scrolling in the corresponding direction. At a button otpuskaniye the system comes back to a mode of normal reproduction.
Function of search of the beginning of records (APS)
The APS function allows to pass automatically by the beginning of records.
At a nazhimaniye on the button (APS FF) during reproduction there is a transition by the beginning of the next record on a disk. For the admission of several records press the APS FF button demanded quantity of times (at a transmission of the last path on a disk the system passes by the beginning of the first).
The single pressing the button (APS REW) allows to pass to repetition of reproduction of the current record. Further pressing the button carry out transition by the beginnings of higher records.
Change of the scheme of reproduction of paths (PROG)
The pressing the PROG button leads to switching of the scheme of reproduction of the paths written down on a disk.
At absence on the screen of the display of any labels of a path will be consistently reproduced as their record on a disk.
The conclusion to the screen of a label 1 means that the scheme of reproduction of the unique (current) record in its continuous repetition is chosen.
At highlighting of the message of RANDOM of a path will be it is made in a casual order that does not exclude probability of repetition of the same record twice.
|
|
At extraction of a compact disc the mode of consecutive reproduction of paths (labels are absent) is automatically established. |
Compact disc extraction
Press the button of emission of a disk — reproduction stops, and the disk is pushed out by the loader with simultaneous shutdown of giving of a food.
|
|
If vytolknuty the disk is not taken in time by the loader, after a while there will be an automatic retraction in the disk drive. |
The indicator of existence of a disk in the disk drive (CD IN)
The message of CD IN is displayed the display at the included food and loaded into the player disk drive a compact disc.
Precautionary measures when using CD player
- In cold and rainy weather owing to increase of humidity of air there can be refusals of functioning of a player — take a disk from the disk drive and carefully ventilate and dry a player.
- At movement on a rough paving there can be admissions of reproduction of laser records.
- Refusals of a player can occur also at excessively high temperature in car salon — turn on the conditioner of air and reduce temperature.
- Do not allow impact on compact discs of direct sunlight.
- Quality of reproduction of laser records considerably depends on a compact disc condition — try not to allow emergence on a surface of a disk of scratches, fingerprints, dirt raids, etc.
- Use 8-сантиметрогвого the transitional adapter can lead to a system exit out of operation.
- The system does not give possibility of listening of the paths which have been written down on compact discs of the CD R standard.
Ruled system uses in a CD changer mode

Change of a disk subject to reproduction
By a nazhimaniye on these buttons (see an illustration the Control panel of an audiosystem of a standard complete set of Bose) is made change of a compact disc subject to reproduction (from among filled in CD changer shop).
Other functions
Scrolling of paths (FF and REW), transition by the beginning of records (APS FF and APS REW) and a choice of the scheme of reproduction (PROG) are made in the manner similar to described above for a mode of a player.
Electromechanical reception aerial
Before including a radio receiver it is necessary to be convinced that near an exit of the aerial there are no people, and that the mast of the aerial can be put forward without hindrances.
Vydviganiye of the aerial occurs automatically at radio receiver inclusion. Switching off of the tuner leads to an automatic ubiraniye of the aerial. If radio is not switched off, the aerial is put forward and cleaned at ignition key turn in the situation "ON" or "OFF".
In order to avoid aerial damage in the course of an automatic wash of the car it is necessary to make sure previously that it is completely cleaned.
Sticking to a mast of the aerial of dirt and extraneous subjects can lead to electric drive jamming. From time to time wipe a mast the humidified pure rags.
