the polarity marks facing you.

compartment.
CAUTION! Do not force the battery case into the battery
compartment. A raised tab on the left side of the battery
case prevents the case from being inserted incorrectly.
5. Pick up the battery door and look at the gasket on the
inside. Make sure the gasket is clean of dust and dirt. If
necessary, wipe it with a soft cloth.

bottom. The battery door will fit in place only if the rounded
corners are even with the back of the PTC.
7. Place the battery door over the opening in the bottom of the
PTC and line up the screws with the holes in the PTC.
8. Tighten the screws that hold the battery door in place.
Tighten them until they are snug but not more.
9. Turn on the PTC. It should not display any warning
messages if the batteries have been inserted properly and
are new.
