Therefore, different PWBs and pickups can be combined freely. Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.

'ER-CD**' display will only be display when error had been detected for the 5 th times. ¥ FM IF Notes: 1. Description of the "FM IF Adjustment" is not carried on this Manual. It is because the IF coil in the FM front end section has been best adjusted in the factory so that its further adjustment is not needed at the field. When replacing the FM front end assembly, no adjustment is needed either. 2. The parts in the FM front end section are prepared in a complete unit, so you can't obtain each part individually.
