• Place the unit away from strong light such as
direct sunlight or inverted flourescent light
which can prevent proper operation of the
remote contoroller.
• 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 contoroller. The buttons of the remote
contoroller 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 contoroller
operation.
