Using the Flat Blade Screwdriver, carefully
release the tabs retaining the top plate in
position. It will be necessary to lift with
one hand while releasing the tabs with
the Screwdriver.
See Figure 5.38.
NOTE:
There are eight retaining tabs. All must be
released as shown in
Figure 5.38.
Lift the PC Board and check the Battery
Packs to PC Board connection to ensure it
is completely seated.
See Figure 5.39.
Visually inspect individual cells of both
battery packs for leaks or ruptures.
See
Figure 5.40.
Reassemble the battery Module. Do not
over tighten the two retaining screws in
the module top. Over-tightening may
damage the threaded brass inserts of the
housing.

NiMH batteries contain Class E corrosive
materials. In the event of battery cell rupture
or leakage, handle battery module wearing
neoprene or natural rubber gloves. Contents
of a ruptured or leaking battery can cause
respiratory irritation. Hypersensitivity to
nickel can cause allergic pulmonary asthma.
Contents of cell coming in contact with skin
can cause skin irritation and chemical burns.
Never, under any circumstances, open the
battery cells. Should an individual cell from a
battery become disassembled, spontaneous
combustion of the negative electrode is
possible. There can be a delay between
exposure to air and spontaneous combustion.
