Getting Started
1. Remove the two body clips from the top of the radio box, and
locate the receiver battery box. Install 4 (four) AAA alkaline
batteries into the battery holder, noting the proper polarity. Make
sure that the switch (located in front of the radio box) is in the
OFF position.
2. Remove the battery door from the bottom of the transmitter.
Install 8 (eight) AA alkaline batteries, noting the proper polarity.
3. Locate and unwrap the receiver antenna wire. Push the receiver
antenna wire through the included flexible antenna tube and insert
the tube into the mount located on the back of the radio box (see

the radio system to malfunction!
4. Install the transmitter antenna by inserting it through hole in
the top of the transmitter and pushing gently until it stops
against the internal mounting base. Gently screw in the antenna
(clockwise) until you feel resistance. Reverse these steps to
