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 are worn out. Chemicals that leak from batteries that come in contact with skin 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 batteries from it.
