Begin by removing the paint from around the holes on the inside
of the bottom cover where it will attach to the stand-offs on the circuit
board. There are two holes; one at each end of the cover (see Figure
25).
Select one battery holder and cut the red wire to 3-1/4” (8.3 cm)
in length. Strip 1/4” (6 mm) of insulation off of the end. These are
stranded wires. Be careful not to knick or break the strands. Leave the
black wire its full, original length.

Repeated insertion and removal of the 2-56 screws used in
the following steps may result in stripping the threads in the
bottom cover. To avoid this, study the illustration and instructions
carefully before inserting the screws. In the event that the 2-56
screw threads do become stripped, you’ll need to replace the
supplied screws with longer screws, along with 2-56 hex nuts.
Mount this holder in the right hand position as shown in Figure
25 using two 2-56 screws. Do NOT over-tighten the screws, as this
may strip the threads. Be sure the wires exit at the left end as shown.
On the second holder, cut the wires as follows:
_ Red: cut to 2-3/4” (7 cm) in length and strip the insulation off
of 1/4” (6 mm) at the end.
_ Black: cut to 4” (10.2 cm) in length and strip the insulation
off of 1/4” (6 mm) at the end.
Position the second holder on the bottom cover oriented as shown
and start a screw in the hole nearest the edge of the cover (closest to
the bottom in Figure 25). Do not tighten this screw yet. Leave it loose
enough so that the other side of the holder can be lifted up off of the
cover far enough to slip wires underneath.
Slip the three wires shown in Figure 25 under the edge of the
holder as follows:
_ Position the red wire so it goes under the holder and around
the nub at the corner.
_ Position the two black wires so the screw will prevent their
being pulled out from under the holder. Be sure the wires lie
flat and do not cross over each other under the holder.
Insert the remaining screw in the holder and tighten both screws.
Wiggle all three wires running under the left battery holder to be
sure they are not being pinched. You should be able to move the free
end of the black wire and see it move where it emerges from under the
holder without interfering with the other wires. If necessary, loosen or
remove the top screw and adjust the wires so each one lies flat under
the holder. Tighten both screws when you are done.
Cut a 1” (2.5 cm) length of the black shrink-tubing supplied and
place it over the end of the red wire on the right hand battery holder.
Twist the ends of the red wire from the right holder and the black
wire from the left holder together to join them. Make the joint small
and smooth. Solder it.
