3. Make sure the + sign on the battery pack is on the same
side as the + sign on the PTC and the straight edge of the
battery pack is facing up (see Figure 5); then insert the
battery pack directly into the bottom of the PTC.
The battery pack has a spacer to prevent it from being
inserted incorrectly.
4. 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.
5. Hold the battery door so the rounded corners are at the
bottom. The battery door will fit in place only if the rounded
corners are even with the back of the PTC.
6. Place the battery door over the opening in the bottom of the
PTC and line up the screws with the holes in the PTC.
7. Tighten the screws that hold the battery door in place.
Tighten them until they are snug but not more.
8. Turn on the PTC. It should not display any warning
messages if the battery pack has been inserted properly
and is charged.
