2 Insert the two supplied batteries (AA/R6) in accordance with the polarity diagram inside the battery compartment.

3 Put the cover onto the remote controller and slide it shut.

Notes:

•If the remote controller doesn’t work reliably, try replacing the batteries.

•Don’t mix new and old batteries or different types of batteries.

•If you intend not to use the remote controller for a long time, remove the batteries to prevent damage from leakage or corrosion.

•Expired batteries should be removed as soon as possi- ble to prevent damage from leakage or corrosion.

Approx. 16 ft. (5 m)

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 con- troller 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 obstacle between it and the AV receiver’s remote con- trol sensor.
