Unpacking

Check that you have received the following items with the VCR:

• Remote commander

• Aerial cable

• R6 (size AA) batteries

The instructions in this manual are for the 8 models: SLV-SE610N, SE610K, 
SE710N, SE710K, SX710N, SX710K, SE810N, and SE810K.  Check your 
model number by looking at the rear panel of your VCR.  
SLV-SE810N is the model used for illustration purposes.  Any difference in 
operation is clearly indicated in the text, for example, “SLV-SE710N only.”

11

Setting up the remote commander

Insert two R6 (size AA) batteries 
by matching the + and – on the 
batteries to the diagram inside the 
battery compartment.

Insert the negative (–) end first, 
then push in and down until the 
positive (+) end clicks into 
position.

You can use this remote 
commander to operate this VCR 
and a Sony TV.  Buttons on the 
remote commander marked with a 
dot (

•

) can be used to operate your 

Sony TV.  If the TV does not have 
the 

 symbol near the remote 

sensor, this remote commander 
will not operate the TV.
