In order to remove and replace the circuit board, the back panel must first be removed by taking out the two screws on the back of the device. To reduce the chances of damaging the meter, remove the battery as soon as the back cover is removed. Next, the four screws that secure the circuit board must be removed. This will free the circuit board to be removed and replaced.
