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.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list).
Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall
be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
•DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations
between individual instruments or/and units.

CAUTION : For continued safety, replace safety critical compo-
nents only with manufacturer's recommended parts (refer to parts
list).
Indicates safety critical components. To reduce the risk of
electric shock, leakage-current or resistance measurements shall
be carried out (exposed parts are acceptably insulated from the
supply circuit) before the appliance is returned to the customer.
•DC voltages are as measured with a high impedance voltmeter.
Values may vary slightly due to variations between individual
instruments or/and units.
