Do not combine different types of batteries (for example, alkaline and
carbon-zinc), or old batteries with fresh ones.
When installing batteries, be sure to follow the correct polarity, as
indicated in the battery compartment. Reversed batteries may cause
damage to the device.
When not using the remote control for a long period of time, remove
the batteries to prevent damage or injury from possible battery
leakage.
Do not try to recharge batteries that are not intended to be recharged;
they can overheat and rupture. Follow the battery manufacturer
directions for the batteries you are using.
Always remove batteries as soon as they become weak. Weak
batteries can leak and severely damage the unit. The battery life
depends on how much the remote control is used. Replace the
batteries when remote control operation becomes erratic.
Do not take apart the batteries, heat them, or throw them into a fire.
