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 2 models: SLV-SE410K and SE510K.  
Check your model number by looking at the rear panel of your VCR.  
SLV-SE510K is the model used for illustration purposes.  Any difference in 
operation is clearly indicated in the text, for example, “SLV-SE410K only.”

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.
