Notes
• Do not mix new batteries with old batteries or
differnt 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 corrosion. If the remote
controller doesn't operate smoothly, replace
both the batteries at the same time.
• The life of the batteries supplied is about six
months but this will vary depending on usage.

• 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.
• If there is any obstacle between the remote
contoroller and the remote control sensor, the
remote controller will not operate.
