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

11、 power cord from the wall outlet, wait at least ve 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 curren

12、t 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 sw

13、itch 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.

14、Ce symbole indique que le fusible utlise est a rapide. Pour une protection permanente, nuntiliser que fusibles de meme type. Ce darnier est la qu le present symbol est appse. 4. CIRCUIT NO. PART NO. DESCRIPTION Note: :North American model only : European model only : Australian model only To reset t

15、he TX-8222 to its factor y defaults, turn it on and, while holding down the VIDEO button, press the STANDBY/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 battery-less memory backup sys- tem (C704) in order to r

16、etain r adio presets and other settings when its unplugged or in the case of a power 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

17、 depends on the environment and will be shorter in humid climates.
