6.8 Changing Batteries
Changing transmitter batteries (“AA” alkaline battery x 4) by unscrewing the battery cover
located on the backside of the transmitter. During battery installation, make sure the
batteries are installed correctly, with “+” to “+” charge and “–” to “–” charge. Also make
sure the screw is tightened after battery installation to avoid water, moisture, dirt, grease,
and other liquid penetration. Do not use lithium ion batteries.
