When performing maintenance on 2010 handheld equipment, occasionally you may find that the entire vehicle mount does not need to be replaced, only the PBCA circuit board, such as in the case of mechanical failure or corrosion.
Zonar provides the internal circuit board (store link) at a lower cost than the full vehicle mount. Instructions for changing the board out are provided below.
Care should be taken when handling circuit boards to ensure that they are kept away from static electricity, liquid or other substances during the exchange process.
What You Will Need

Installing the New Circuit Board
- Insert the cable connector into the new circuit board by lining up the grooves on the connector and socket.
When pushing the connector into place, support the back of the circuit board, directly behind the connector, with a finger to ensure it doesn't crack as pressure is applied to the connector.
