Notes:

The remote controller may not work reliably if the AV receiver is subjected to bright light, such as direct sun- light or inverter-type fluorescent lights. Keep this in mind when installing.

If another remote controller of the same type is used in the same room, or the AV receiver is installed close to equipment that uses infrared rays, the remote control- ler may not work reliably.

Don’t put anything, such as a book, on the remote con- troller, because the buttons may be pressed inadvert- ently, thereby draining the batteries.

The remote controller may not work reliably if the AV receiver is installed in a rack behind colored glass doors. Keep this in mind when installing.

The remote controller will not work if there’s an obsta- cle between it and the AV receiver’s remote control sensor.
