GF82.60-P-2003SK Volume/Tone Adjustments, Function

All volume and tone settings are carried out by the radio (A2) at the operating unit. It is necessary to differentiate between audio sources and service sources:
Audio sources are:
^ CD disk drive
^ Radio

Service sources are:
^ Announcement of the traffic information radio channel
^ Telephone (TEL)
^ Voice control system (VCS [SBS])

Volume setting
The volume setting is regulated at the combination push and rotary button of the radio (A2) for each of the selected audio sources.

In addition, the volume can be adjusted separately in all the audio and service areas (e.g. telephone, traffic information radio channel). The volume of the traffic information can be increased or decreased using the "Volume" button.
Using the "Reset" function, predefined settings for all sound parameters, including volume, can be selected and reset to the manufacturer default settings.

Speed-dependent volume control (SDV)
The volume is adapted to the noise situation in the interior using the speed-dependent volume control. The vehicle speed signal is used as a relationship indicator by the instrument cluster (A1) when doing this.

In vehicles with code (810) Sound system up to 31.8.06 the speed-dependent volume control is supplemented by automatic vehicle interior noise adaptation. The signal input at the sound amplifier microphone (B25/6) is used as another relationship indicator when doing this.

Muting
If the user presses the "Mute" function key, the audio source currently being listened to is muted and the CD drive is switched to a pause status. The muting function status can also be triggered automatically.
When a telephone call comes in, the radio (A2) switches to telephone mode and mutes the audio source.

Tone setting
The radio (A2) has manual tone settings (bass, treble, balance, fader) available for each audio source. The "AUDIO" function status can be reached from any function status (except "AUTO-ON").

The bass is shown on the display as the first tone setting called up. By pressing the "AUDIO" function key repeatedly, the other tone controls for treble, balance (left, right), fader (front, rear), increased volume and traffic announcements can be called up. The messages of the "AUDIO" function state are output on the display. The tone control only relates to the active system function status. If the tone emphasis is changed (balance, fader) the volume relationship between the individual speakers changes relative to each other. The "Balance" and "Fading" adjustments can be achieved by pressing the main function key for sound distribution in the left control panel. Processing of the signals for the required volume and tone adjustments is performed by the radio (A2).
