• 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. 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.
Operation
Other Information
• 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 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.

the power cord is plugged in for the first time,
the A-905TX will automatically enter the standby
state and the STANDBY indicator will light (same
condition after step 2.)
• If the AC power cord (mains lead) is connected
to the AC outlet of another component, that
component’s AC power cord (mains lead) must
be connected to the wall outlet (the mains) to
supply power to the unit. If the component has
a power switch, it must be set to On.
• Leave POWER switch on. If you set POWER
switch to off:
– the remote controller will not operate, and
– the timer functions will not operate.
• If you do not use the unit for a long time, set
POWER to off by pressing POWER switch again.
• The unit may cause a power surge on your home
circuit when you turn it on. If this interferes with
any other devices connected to the same circuit, plug this unit into another outlet on a separate circuit.
