Precautions

1.Recording Copyright—Unless it’s for personal use only, recording copyrighted material is illegal with- out the permission of the copyright holder.

2.AC Fuse—The AC fuse inside the unit is not user- serviceable. If you cannot turn on the unit, contact your Onkyo dealer.

3.Care—Occasionally you should dust the unit all over with a soft cloth. For stubborn stains, use a soft cloth dampened with a weak solution of mild deter- gent and water. Dry the unit immediately afterwards with a clean cloth. Don’t use abrasive cloths, thin- ners, alcohol, or other chemical solvents, because they may damage the finish or remove the panel let- tering.

4.Power

WARNING

BEFORE PLUGGING IN THE UNIT FOR THE FIRST TIME, READ THE FOLLOWING SEC- TION CAREFULLY.

AC outlet voltages vary from country to country. Make sure that the voltage in your area meets the voltage requirements printed on the unit’s rear panel (e.g., AC 230 V, 50 Hz or AC 120 V, 60 Hz).

Some models have a voltage selector switch for compatibility with power systems around the world. Before you plug in such a model, make sure that the voltage selector is set to the correct voltage for your area.

Setting the [STANDBY/ON] switch to STANDBY does not fully shutdown the unit. If you do not intend to use the unit for an extended period, remove the power cord from the AC outlet.

5.Never Touch this Unit with Wet Hands—Never handle this unit or its power cord while your hands are wet or damp. If water or any other liquid gets inside this unit, have it checked by your Onkyo dealer.

6.Handling Notes

•If you need to transport this unit, use the original packaging to pack it how it was when you origi- nally bought it.

•Do not leave rubber or plastic items on this unit for a long time, because they may leave marks on the case.

•This unit’s top and rear panels may get warm after prolonged use. This is normal.

•If you do not use this unit for a long time, it may not work properly the next time you turn it on, so be sure to use it occasionally.

Memory Backup

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.
