SERVICE PROCEDURE

TX-SR573

1. Replacing the fuses

This symbol located near the fuse indicates that the

fuse used is show 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 utilise est e lent.

Pour une protection permanente, n'utiliser que des fusibles de meme

type. Ce demier est indique la qu le present symbol est apposre.

2. To initialize the unit

The AV receiver uses a battery-less memory backup system in order to retain radio presets and other settings

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

Although no batteries are required, the AV receiver must be plugged into an AC outlet in order to charge the

backup system. Once it has been charged, the AV receiver will retain the settings for several weeks,

although this depends on the environment and will be shorter in humid climates.

1. Press and the hold down the VIDEO 1/VCR button, then press the STANDBY/ON button when the unit is Power on.

2. After " Clear " is displayed, the preset memory and each mode stored in the memory, are initialized and will return to

the factory settings.

4. Memory Backup

Main microprocessor Q701 only.

1. Press and the hold down the DISPLAY button, then press the STANDBY/ON button when the unit is Power on.

Version is displayed on FL display only for 3seconds.

2. Press the STANDBY/ON button to Power off.

3. To check version of microprocessor
