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 and hold down the VIDEO-1 button, then press the

STANDBY/ON button.

2.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.

3. Unplug the power supply cord.

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.

1. Replacing the fuses

This symbol located near the fuses indicates that the

fuse used is fast operating type. For continued protection against

fire hazard, replace with same type fuse.For fuse rating refer to

the marking adjacent to the symbol.

Ce symbole indique que le fusible utlise est a rapide.

Pour une protection permanente, n'untiliser que fusibles de

meme type.Ce darnier est la qu le present symbol est

appse.
