3. Safety-check out

(U.S.A. model only)
After correcting the original service problem, perform the
following safety check before releasing the set to the customer.

Leakage Current Check

Measure leakage current to a known earth ground(water pipe,
conduit, etc.) by connecting a leakage current tester between
the earth ground and exposed metal parts of the appliance
(input/output terminals, screwheads,metal overlays, etc.).
Plug the power supply cord directly into a 120V AC 60 Hz outlet
and turn Standby switch on. Any current meausred must not
exceed 0.5mA.

4. Memory Preservation

This unit does not require memory preservation batteries.
built-in memory po wer back-up system preserves the contents
of the memory during power failures and even when the unit is
unplugged. The unit must be plugged in order to charge the
back-up system.
The memory preservation period after the unit has been
unplugged varies depending on climate and placement of the
unit. On the average, memory contents are protected over a
period of a few weeks after the last time the unit has been
unplugged. This period is shorter when the unit is e

xposed to a

highly humid climate.

2. To initialize the unit

This device employs a microprocessor to perform various
functions and operations. If interference generated by an
external power supply, radio wave, or other electrical source
results in accident which causes the specified operations
and functions to operate abnormally.
To perform a result, please follow the procedure below.

1.Press the STANDBY ON button to turn on the unit.

2.Press and hold down the VIDEO 1 button, then press the
STANDBY/ON button.

3.After "CLEAR" is displayed, the preset memory and each
mode stored in the memory, such as surround, are
initialized and will return to the factory setting.

4.Unplug the power supply cord.

NOTE

.
.

THE COMPONENTS IDENTIFIED BY MARK ! ARE CRITICAL FOR SAFETY.
REPLACE ON LY WITH PART NUMBER SPECIFIED.

.

VOLTAGE (MEASURED WITH VOLTMETER) IS DC VOLTAGE (NO INPUT SIGNAL)
ELECTROLYTIC CAPACITORS ( ) ARE IN uF/WV.

.

ALL CAPACITORS ARE IN pF/50WV UNLESS OTHERWISE NOTED.

.

EX) 030-3pF 330-33pF 331-330pF 333pF-0.033uF
ALL RESISTORS ARE IN OHMS 1/4WATTS UNLESS OTHERWISE NOTED.

.

THE THICK LINE ON PC BOARD ARE THE PRINTING SIDE OF THE PARTS.
EX) PRINTING SIDE
CIRCUIT IS SUBJECT TO CHANGE FOR IMPROVEMENT.
