Radio clock
WARNING: This page does not describe the selected car, but rather 15 other vehicles, including the 2008 Audi S4, 2008 Audi RS 4, 2008 Audi A4, 2007 Audi S4, and 2007 Audi RS 4. However, it is still accessible from the selected car via links, so may be relevant.
If an acceptable radio clock signal is received, clock automatically switches to "radio-controlled quartz clock" operating mode. The radio clock reception symbol (radio tower radiating waves) appears in display. If the clock does not receive a valid signal, it automatically switches to "quartz clock" mode after 3 days and radio clock reception symbol goes out.
