Do not unscrew the white nylon hex bolt of the antenna.
Do not unscrew the four round topped hex bolts
Step 3.
Unscrew the two Phillips head screws about ¼ inch. Do not fully unscrew or remove
these screws to avoid destroying the seal in which they are set.
Step 4.
Carefully cut the silicone seal all around the base of the box where it meets the
mounting plate.
Step 5.
Carefully separate the box from the mounting plate by inserting a flat head screw-
driver in the notch where the box meets the link and turning.
Avoid all contact with the tiny white interrupter switches.
Step 6.
Remove the battery closest to the indicator
light first, the middle battery second, and the battery
furthest from the indicator LED last. The batteries can
easily be removed by hand. Gently apply pressure
in the direction of the negative pole while lifting out
the positive pole.
Tip:
Alternative method: use a very small, flat head
screwdriver. Gently place the tip of the screwdriver
against the top of the negative pole of the battery closest
to the indicator light and, using the side of the box for support, lift the battery up until it can be
grasped and removed by hand.
