SAFETY PRECAUTIONS
The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the power
cord is less than 460 kohms, the unit is defective.
CAUTION Please heed the points listed below during servicing and inspection.

CAUTION IN SERVICING
Initializing AV SURROUND RECEIVER/AM-
PLIFIER
AV SURROUND RECEIVER/AMPLIFIER initialization should be
performed when the µcom, peripheral parts of µcom, and Digital
P.W.B. are replaced.
1. Switch off the unit.
2. Hold the following SPEAKERS-A button and SPEAKERS-B
button, and switch on the unit.
3. Check that the entire display is flashing with an interval of
about 1 second, and release your fingers from the 2 buttons
and the microprocessor will be initialized.
Note: If step 3 does not work, start over from step 1.
All user settings will be lost and this factory setting will
be recovered when this initialization mode.
So make sure to memorize your setting for restoring
after the initialization.
