Function check
Set radio as follows: Set station with poor reception (music) and fader, bass, treble and balance in
position 0 (shown in display).
Check AM and FM wave bands by driving in a circle in a yard (open-air grounds) to establish the
reception quality.
Possibly repeat the test with an identical vehicle for comparison.
It is absolutely essential to perform the comparison measurement at the same location and with the same
station setting .
Repeat the test after replacing a component.
