To change the battery:
1. Separate the two halves of the PTT-Z housing by securely holding the back cover and rotating
the front cover in a counter-clockwise direction until the two halves come apart.
2. Locate the battery holder inside of the device. Remove the old battery from the battery
holder if one is installed. A ball point pen can be used to push the battery out of the holder if
needed.
3. Insert a new CR2032 3-volt coin cell battery into the battery holder, observing proper polarity.
The positive side of the battery (marked with a “+” sign) should face away from the circuit board.
3. Reinsert the two halves of the transmitter housing and rotate the top cover clockwise to
tighten.
If You bought PTT-U then you need screwdriver to remove 4 screws.
