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 objects on the remote controller. Its buttons may be
pressed by mistake and drain the batteries.
• Make sure the audio rack doors do not have colored glass.
Placing the unit behind such doors may prevent proper remote
controller operation.
• If there is any obstacle between the remote controller and the
remote control sensor, the remote controller will not operate.
