The backup battery maintains the memory while you are changing the battery pack.
Follow these steps to change the battery pack:
1) Turn the FieldBook off and lay it face down.
2) Loosen the six screws, pull the bottom of the case straight up, and rotate it over the top,
being careful not to pull on the cable connecting the top of the case to the bottom.
3) At the lower left corner of the board, disconnect the white molex connector that leads to
the battery pack.
4) Pull out the battery pack and replace it with a fresh pack.
5) Plug in the white molex connector of the new pack, being sure to align the pins properly.
6) Check the six hex standoffs which are mounted on the battery board and tighten them if
necessary. Be sure the holes in the battery holder are aligned with the holes in the hex
standoffs.
7) Before closing the case, check the rubber gasket for nicks, dirt, etc. Clean or replace it as
necessary to ensure a proper seal.
8) Be sure to seat the six aluminum washers in place properly. Insert and tighten the screws
until they are snug, but not over-tightened. The aluminum washers must not extend past the
case edge. (Replacement washers are available from Juniper Systems.)
