Before using this unit

Setting the voltage selector
(Worldwide models only)
Worldwide models are equipped with a voltage selector so that you
can set your TX-NR900 to conform with local power supplies. Be
sure to set this switch to match the voltage of the power supply in
your area before plugging in the unit.
Determine the proper voltage for your area: 220-230 V or 120 V. If
the preset voltage is not correct for your area, insert a screwdriver
into the groove in the switch and slide the switch all the way to the
top (120 V) or bottom (220-230 V), whichever is appropriate.

Connecting the power cord
(Other than North American and Australian models)
Plug the supplied power cord into this AC INLET.
• Do not use a power cord other than the one supplied with the TX-
NR900/900E. The power cord supplied is designed for use with
the TX-NR900/900E and should not be used with any other
device.
• Never have the power cord disconnected from the TX-NR900/
900E while the other end is plugged into the wall outlet. Doing
so may cause an electric shock. Always connect by plugging into
the wall outlet last and disconnect by unplugging from the wall
outlet first.

Notes:
• Do not mix new batteries with old batteries or different kinds of batteries.
• To avoid corrosion, remove the batteries if the remote controller
will not be used for a long time.
• Remove dead batteries immediately to avoid damage from corrosion.
If the remote controller does not operate smoothly, remove the old
batteries and replace them both with two new AA batteries.

Using the remote controller

Point the remote controller toward the remote control sensor. The
STANDBY indicator lights up when the unit receives a signal from
the remote controller.

Notes:
• Make sure that the remote control sensor is not subject to strong
light such as direct sunlight or inverted fluorescent light for it
may prevent proper operation of the remote controller.
• Using another remote controller in the same room or using the
TX-NR900/900E near equipment that 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 TX-NR900/900E 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.
