Sony 3-284-083-41(1) User Manual

Insert two R6 (size-AA) batteries in the 

 

RM-AAU020 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 60).

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.

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 

 

Before you perform Auto Calibration, install 
and connect the speakers (page 13, 14).
• The AUTO CAL MIC jack is used for the 

supplied optimizer microphone only. Do not 
connect other microphones to this jack. 
Doing so may damage the receiver and the 
microphone.

• During calibration, the sound that comes out 

of the speakers is very loud. The volume of 
the sound cannot be adjusted. Pay attention 
to the presence of children or to the effect on 
your neighborhood.

• Perform Auto Calibration in a quiet 

environment to avoid the effect of noise and 
to get a more accurate measurement.

• If there are any obstacles in the path between 

the optimizer microphone and the speakers, 
the calibration cannot be performed 
correctly. Remove any obstacles from the 
measurement area to avoid measurement 
error.
