SERVICE PROCEDURE

1. Replacing the fuses

This symbol located near the fuse indicates that the

fuse used is slow 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 appose.

2. To initialize the unit

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

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

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

Although no batteries are required, the AV receiver must be plugged into a wall 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.

3. To check version of microprocessor

<Note>

Main microprocessor Q701 only.

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

The version will be displayed on FL display only for 3 seconds.

2. Press STANDBY/ON button to power off.
