Changing the remote controller
mode
When you use any Onkyo products other than the
NC-500 in the same room, the operations made
with the NC-500's remote controller may also
cause the other Onkyo products to operate. To
avoid this, you can change the remote controller
mode both for the NC-500 and its remote
controller choosing from three modes (1, 2 or 3).
To change the remote controller mode for the
remote controller, hold the STANDBY button on
the remote controller and press the SELECT
button, then release these buttons simultaneously.
Within 5 seconds after releasing the buttons, enter
the appropriate mode (1, 2 or 3) using the numeric
keys. The default mode is 1 for both the remote
controller and NC-500.
After changing the remote controller mode, make
sure that the remote control code on the NC-500 is
set to the same mode as the remote controller. (see

If the NC-500 is located inside a rack or a
cabinet that will not allow infrared beams to
reach its IR sensor, you will need to relay
beams with an external sensor.
Connect the external sensor to IR IN input.
Then, place the sensor in an unblocked
location at which you can easily point with
the remote controller.
