MODEL 414.700 1N as of 231763 with CODE (EU0) Sound 30 radio with single CD disk drive
A "Background lighting and speed-dependent volume control inoperable" customer complaint does not refer to a defective component, but rather to the various options involved in coding the radio.
Coding for daytime illumination ON:
When the radio is switched on, the display and function keys are illuminated (not dimmable).
Coding for daytime illumination OFF:
Illumination of display and function keys performed as a function of circuit 58d.
If the speed-dependent volume control (GAL) is not increased enough, the volume adaptation can be set to Stage 2.
