Radio Test Functions

With the ignition switch in KL R the radio can be switched into the test function mode by pressing and holding the WB (weather band) until the MID displays a serial number in the MID main display.

The test functions include:

• Radio Serial Number
• Radio Production Date
• DSP Recognition
• Road speed dependent volume control (GAL 1 -4)
• Station Signal Strength

The road speed dependent volume control can be adjusted to make the volume increase more audible (4) or less audible (1).
