• Do not touch this receiver’s bottom panel while the 

power is turned on. The bottom panel gets hot when 
the power is on, and touching it could cause burns.

Incorrect use of batteries may result in such hazards as 
leakage and bursting. Observe the following precautions:

• Never use new and old batteries together.

• Insert the plus and minus sides of the batteries 

properly according to the marks in the battery case.

• Batteries with the same shape may have different 

voltages. Do not use different batteries together.

with governmental regulations or environmental 
public instruction’s rules that apply in your country or 
area.

• WARNING

Do not use or store batteries in direct sunlight or 
other excessively hot place, such as inside a car or 
near a heater. This can cause batteries to leak, 
overheat, explode or catch fire. It can also reduce the 
life or performance of batteries.

The remote control may not work properly if:

• There are obstacles between the remote control and 

the receiver’s remote sensor.

• Direct sunlight or fluorescent light is shining onto the 

remote sensor.
