1-4. Adjustment of STEREO (adjustment of 456k-VCO)
Adjust in TEST MODE
• How to enter the test mode
While pressing on [FM] and Preset [6] keys, reset the unit.
• Adjustment method
Complete on condition that show “STANDBY” when press-
ing on Preset [1] and Preset [6] keys for 1 second or more.
(Writing adjustment valve to the E2PROM.)
Effect of adjustment is in cofirmation of adjustment status
at Preset [4] key.
• Display of Preset [4]
Adjustment OK:“EPO” (7-segment LCD model)
Adjustment NG:“EPE” (7-segment LCD model)
• Releasing the test mode
Reset mode only.
ACC off, Power off, Power down and Remove the panel
mode is not releasing.
