Insert two R6 (size-AA) batteries in the 
RM-AAU013 remote commander.
Observe the correct polarity when installing 
batteries.
Notes
• Do not leave the remote in an extremely hot or 
humid place.
• Do not use a new battery with old ones.
• Do not mix alkaline batteries and other kinds of 
batteries.
• Do not expose the remote sensor to direct sunlight 
or lighting apparatuses. Doing so may cause a 
malfunction.
• If you do not intend to use the remote for an 
extended period of time, remove the batteries to 
avoid possible damage from battery leakage and 
corrosion.
• When you replace the batteries, the remote buttons 
may be reset to their factory settings. If this 
happens, reassign the button again (page 53).
Tip
Under normal conditions, the batteries should last 
for about 3 months. When the remote no longer 
operates the receiver, replace all the batteries with 
new ones.
6: Calibrating the 
appropriate settings 
automatically 
(AUTO CALIBRATION)
This receiver is equipped with D.C.A.C. 
(Digital Cinema Auto Calibration) 
Technology which allows you to perform 
automatic calibration as follows:
• Check the connection between each speaker 
and the receiver.
• Adjust the speaker level.
• Measure the distance of each speaker to your 
listening position.
You can also adjust the speaker levels and 
balance manually. For details, see 
“7: Adjusting the speaker levels and balance 
(TEST TONE)” (page 26)
