12 Basic functions
12.1 Turning on/off
To turn on the device, briefly press the “PWR/MUTE” button on the operating unit. To turn the device off, please press the
“PWR/MUTE” button for more than two seconds. The device will then turn off.
Note:
If the device is activated after the ignition has been started, it will automatically turn on and off with the ignition during
subsequent operation. A prerequisite for this is that the contact A7 is connected to terminal # 15 of the vehicle (see Illustr. 8.3
and Illustr. 8.4).
Caution!
When the radio is turned on, an automatic antenna that may be installed on the vehicle will also be extended. Before driving
into a car wash, you should therefore always turn off the device in order to avoid damages to the antenna as well as the
vehicle.
12.2 Changing the volume
The volume of the device can be changed with the round control dial . The current volume of the device will be indicated on
the display in the process. The volume scale ranges from 0 - 45.
Note:
The volume is not saved when the car radio is turned off. When you switch the car radio back on, the volume level
corresponds to the volume selected in the menu item “INVOL” (see p. 37).
Note:
Don’t use the car radio at an excessive volume. Otherwise there is the risk that you will permanently damage your hearing.
Please consider that while using the device you should still be in the position of perceiving your surroundings (warning
signals, sirens, etc.).
Only make time-consuming or complex changes to your device settings whilst parked. Otherwise your concentration might
be affected by the changes.
