Sony STRDG720 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 74).

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.

You can select the front speakers you want to 
drive. 
Be sure to use the buttons on the receiver for 
this operation.

To turn off the speaker output, press 
SPEAKERS (OFF/A/B) repeatedly until the 
“SP A” and “SP B” indicators on the display 
light off.

You cannot switch the front speaker system by 
pressing SPEAKERS (OFF/A/B) when the 
headphones are connected to the receiver.
