2. To initialize the unit

The TX-8222 contain a micro processor for signal processing

and control functions. In very rare situations, severe interference,

noise from an external source, or static electricity may cause it to lockup.

In the unlikely event that this happens, unplug the power cord from the

wall outlet, wait at least Þve seconds, and then plug it back in again.

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.

DESCRIPTION

Note: <D>:North American model only

<P>: European model only

<A>: Australian model only

To reset the TX-8222 to its f actor y defaults, turn it on and,

while holding down the VIDEO button, press the

ST ANDBY/ON button. When the reset is complete,

"Clear" appears on the display and the TX-8222 enter

Standby mode.

Memory backup

The TX-8222 use a batter y-less memory backup sys-

tem (C704) in order to retain r adio presets and other settings

when it's unplugged or in the case of a po wer failure.

Although no batteries are required, it must be plugged

into an AC outlet in order to charge the backup system.

Once it has been charged, the TX-8222 will retain the

settings for several weeks, although this depends on

the environment and will be shorter in humid climates.
