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.

To use the remote controller, point it at the AV receiver’s 
remote control sensor, as shown below.

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.
