Sony 3-295-946-12(1) User Manual

Insert two R6 (size-AA) batteries in the 

 

RM-AAU023 Remote Commander.
Observe the correct polarity when installing 
batteries.

• Do not leave the remote in an extremely hot or 

humid place.

• Do not use a new battery with old ones.
• Do not mix manganese 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 buttons again (page 61).

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.

 

This receiver is equipped with DCAC (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.

• Measure the speaker polarity.
• Measure the frequency characteristics.*

* The measurement result is not utilized for signals 

with a sampling frequency of more than 96 kHz.

The DCAC is designed to obtain proper sound 
balance in your room. However, you can 
adjust the speaker levels and balance manually 
according to your preference. For details, see
