CAUTION
Improper use of batteries can result in chemical leakage or explosion. Be sure to follow the instructions below.
•  Do not mix batteries of different types. Different types of batteries have different characteristics.
•  Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries or cause 

chemical leakage in old batteries.

•  Remove batteries as soon as they have worn out. Chemicals that leak from batteries can cause a rash. If you fi nd 

any chemical leakage, wipe thoroughly with a cloth.

•  The batteries supplied with this product may have a shorter life expectancy due to storage conditions.
•  If you will not be using the remote control unit for an extended period of time, remove the batteries from it.
•  When replacing the batteries, use zinc-carbon batteries instead of alkaline ones.

Note on disposing batteries:
The batteries provided contain no harmful materials such as cadmium, lead or mercury.
Regulations concerning used batteries stipulate that batteries may no longer be thrown out with the household 
rubbish. Deposit any used batteries free of charge into the designated collection containers set up at commercial 
businesses.

Use the remote control unit by pointing it towards the remote control sensor. Objects between the remote control 
unit and sensor may prevent proper operation.

•  Do not expose the remote control unit to shock. In addition, do not expose the remote control unit to liquids, 

and do not place in an area with high humidity.

•  Do not install or place the remote control unit under direct sunlight. The heat 

may cause deformation of the unit.

the TV is under direct sunlight or strong lighting. In such cases, change the 
angle of the lighting or the TV, or operate the remote control unit closer to the
