Installing or Replacing Remote Control Batteries
When the batteries are low, the red light on the remote control blinks twice when a button is pushed.
Insert two AA non-rechargeable batteries into the remote control ensuring that you place them with the
proper polarity.
1 Press and open the cover on the back of the remote control.
2 Insert the batteries into the remote control, and make sure that you match polarities.
3 Close the cover.
CAUTION: Use only the size and type of batteries specified.
Be sure to follow the correct polarity when installing the batteries as indicated in the
battery compartment. Reversed batteries may cause damage to the device.
Do not mix different types of batteries together (e.g., alkaline and carbon-zinc) or old
batteries with fresh ones.
When not using the remote 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’s 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 batteries
when remote control operation becomes erratic.
Do not take apart the batteries, heat them, or throw them into a fire.
