Operations Using the Remote RM-AAU002
You can use the remote RM-AAU002 to operate
the components in your system.
Inserting batteries into the
remote
Insert R6 (size-AA) batteries with the + and –
properly oriented in the battery compartment.
When using the remote, point it at the remote
sensor on the receiver.
Tip
Under normal conditions, the batteries should last for
about 6 months. When the remote no longer operates
the receiver, replace all batteries with new ones.
Notes
•Do not leave the remote in an extremely hot or humid
place.
•Do not use a new battery with an old one.
•Do not expose the remote sensor to direct sunlight or
lighting apparatuses. Doing so may cause a
malfunction.
•If you don’t use the remote for an extended period of
time, remove the batteries to avoid possible damage
from battery leakage and corrosion.
*The MASTER VOL +, numeric button 5 and H
buttons have a tactile dot. Use the tactile dot as a
reference when operating the receiver and other
audio/video components.
