AM AND FM WAVE BANDS, DIAGNOSIS, FUNCTION CHECK, AS - AD82.62-P-3000-01A 
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.
