Notes on batteries

• Change both batteries when the operation range of the 

remote control decreases.

• Use AAA, R03, UM-4 batteries.
• Make sure that the polarities are correct. See the 

illustration inside the battery compartment.

• Remove the batteries if the remote control is not to be 

used for an extended period of time.

• Do not use old batteries together with new ones.
• 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.

The remote control transmits a directional infrared beam. 
Be sure to aim the remote control directly at the remote 
control sensor on the front panel of the receiver during 
operation.

Notes

• The area between the remote control and the receiver must be 

clear of large obstacles.

• Do not spill water or other liquids on the remote control.
• Do not drop the remote control.
• Do not leave or store the remote control in the following types 

of conditions:
– high humidity, such as near a bath
– high temperature, such as near a heater or a stove 
– extremely low temperatures
– dusty places.

• Do not expose the remote control sensor to strong lighting, in 

particular, an inverter type fluorescent lamp; otherwise, the 
remote control may not work properly. If necessary, position the 
system away from direct lighting.
