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.
