Yamaha RX-V663 User Manual

■ Installing batteries in the remote control

• Change all of the batteries if you notice that the operation range 

of the remote control decreases.

• Do not use an old battery and a new one together.
• Do not use different types of batteries (such as alkaline and 

manganese batteries) together. Read the packaging carefully as 
these different types of batteries may have the same shape and 
color.

• If the batteries have leaked, dispose of them immediately. Avoid 

touching the leaked material or letting it come into contact with 
clothing, etc. Clean the battery compartment thoroughly before 
installing new batteries.

• Do not throw away batteries with general house waste; dispose 

of them correctly in accordance with your local regulations.

• If the remote control is without batteries for more than 2 

minutes, or if exhausted batteries remain in the remote control, 
the contents of the memory may be cleared. When the memory 
is cleared, insert new batteries and set up the remote control 
code.
