HD Electric PRX Series Replacement Instructions

HDE's PRX Series Proximity Voltage Detector Battery Replacement Kit consists of one overlay, one
battery with tape attached and three switch plungers. To change the battery, follow these
instructions:
1. Carefully remove the overlay of the PRX (Figure 1) and
discard. Remove the switch plungers and set aside in a
safe place, you will need them once the battery
replacement is complete. Spare plungers have been
included in the battery replacement kit if needed.
2. Once the overlay is removed, remove the two screws on
the front of the instrument. Then carefully use a
screwdriver to slide the chassis out of the housing
(Figure 2).
3. Clean the front surface of the housing to remove any
adhesive that may still be on the instrument. Adhesive
remover or rubbing alcohol is recommended. If using
adhesive remover, make sure the housing is cleaned with
alcohol so no oily residue remains.
4. Once the chassis is removed, carefully lift up
the shielding, unplug the battery and remove
it (Figure 3). Be careful while doing this so
no damage is done to the board.
