2.1.1. Installing remote control Batteries
To install remote control batteries:
1. Open the battery cover.
2. Insert two AAA batteries into the battery compartment. Make sure that the + and –
symbols on the batteries match the + and – symbols in the battery compartment.
3. Replace the cover.
Battery precautions:
Improper use of batteries can result in a leakage of chemicals and/or explosion. Be
sure to follow the instructions below.
 Place batteries with their terminals corresponding to the (+) and (–)indications.
 Different types of batteries have different characteristics. Do not mix batteries of
different types.
 Do not mix old and new batteries. Mixing old and new batteries can shorten the
life of new batteries and/or cause old batteries to leak chemicals.
 Remove batteries as soon as they are non-operable. Chemicals that leak from batteries can cause a
rash. If chemical leakage is found, wipe with a cloth.
 Dispose of batteries in a proper manner.
 If the remote control is not used for an extended period of time, remove the batteries.
