Installing the remote controller batteries
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.
Using the remote controller
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.
