ADJUSTMENT
1. IC10 (X34-) -The Tuner adjustment method
• When IC10 and its circumference are repaired, according
to the following order, it readjusts if needed.
• The adjustment item changes with parts to exchange. Please
refer to "Parts vs Adjustment item table".

1-4. Adjustment of STEREO (adjustment of 456k-VCO)
Adjust in TEST MODE
• How to enter the test mode
Refer to “TEST MODE”.
• Adjustment method
While in test mode and all lights are lit (STANDBY), press
and hold [1] key and press [6] key for 3 seconds or longer.
(Adjusted data will be written on E2PROM.)
Effect of adjustment is in cofirmation of adjustment status
at Preset [AM] key.
• Display of Preset [AM]
Adjustment OK: “E2P OK” (14-segment display model)
Adjustment NG: “E2P ERR” (14-segment display model)
• How to clear the test mode
Refer to “TEST MODE”.
