1. Remove the battery compartment cover by pressing and sliding it

out.

2. Insert two AA (R6- or UM-3)-size batteries into the battery com-

partment. Carefully follow the polarity diagram (positive (+) and
negative (–) symbols) inside the battery compartment.

3. After batteries are installed and seated correctly, replace the com-

partment cover.

Notes
• Do not mix new batteries with old batteries or different kinds of

batteries.

• To avoid corrosion, remove the batteries if the remote controller

is not to be used for a long time.

• Remove dead batteries immediately to avoid damage from cor-

rosion. If the remote controller doesn’t operate smoothly, replace
both the batteries at the same time.

Point the remote controller toward the remote control sensor.

Notes
• Place the unit away from strong light such as direct sunlight or

inverted fluorescent light which can prevent proper operation of
the remote controller.

• Using another remote controller of the same type in the same

room or using the unit near equipment which uses infrared rays
may cause operational interference.

• Do not put any object such as a book on the remote controller.

The buttons of the remote controller may be pressed by mistake
and drain the batteries.

• Make sure the audio rack doors do not have colored glass. Plac-

ing the unit behind such doors may prevent proper remote con-
troller operation.

• If there is any obstacle between the remote controller and the

remote control sensor, the remote controller will not operate.
