2. Twist the small bladed tool, or small coin, between the two halves in order to separate the case.
3. Remove the battery (2) from the transmitter.
Installation Procedure
1. Install the battery (2) with the positive side down into the transmitter.
2. Ensure that the seal (7) is in position. Align the two halves of the case (6, 4), and snap the two halves together.
3. Verify the operation of the transmitter.
4. A malfunctioning transmitter may need resynchronization.
