CAUTION
Improper use of batteries can result in chemical leakage or explo-
sion. Be sure to follow the instructions below.

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
find any chemical leakage, wipe thoroughly with a cloth.
The batteries supplied with this product may have a shorter life ex-
pectancy due to storage conditions.
If you will not be using the remote control unit for an extended period

tive area or country.
