following operations.
1 Observe backplate; notice what must be
present:
If there is a raised surface where the ‘flat’
should be and/or if there is no recessed circle,
replace backplate (610015-503). Remove
battery holder before discarding old
backplate.
NOTE:Observe back of LCD board. If back of
LCD board does not have a metal bar, you
must replace this board.
2 Apply a moderate amount of force to the side
of each battery contact. Contact should hold
firm. If it does not, take battery contact off and
clean any dried epoxy off of metal conducting
surface on PC board.
Obtain a new battery contact (610067-1) and
solder to PC board, noting proper
positioning.
Before soldering, screw contact onto PC board
with appropriate hardware.
Lastly, tighten to specifications (approx. 12-16
in/oz.) or until moderately firm. Take note that
black fiber washer is not destroyed. Perform
this step whether epoxy was adequate or
contact had to be soldered.
