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 �ALL OFF� when pressing on [PRESET 1] and [PRESET 6] keys. (Writing adjustment valve to the EEPROM.) Effect of adjustment is in cofirmation of adjustment status at [PRESET 4] key. � Display of [PRESET 4] Adjustment �OK� : 14 seg model �E2P OK�, 7 seg model �EPO� Adjustment �NG� : 14 seg model �E2P ERR�, 7 seg model �EPE� � Releasing the test mode Reset mode only. ACC off, Power off, Power down and Remove the panel mode is not releasing.
