WARNING
FIRE AND EXPLOSION HAZARD
To reduce the risk of fire or explosion:
D Do not remove or install the battery in a hazard-
ous location.
D The internal (9a and 9b or 16) and external (44
or 64) ground wires for the display must be
correctly connected.
NOTE:
D See page 35 for battery part numbers.
D Numbers in parenthesis in the text refer to the
reference numbers in the figures (Fig.) and in the
parts lists.
D The Grand Totalizer value is stored to non-volatile
memory when the battery low condition first ap-
pears. If the battery low icon has been displayed
for a significant amount of time before the battery is
replaced, the flow data since the icon appeared will
be lost. The Grand Totalizer value can be manually
stored to non-volatile memory by entering the setup
mode and exiting setup mode. If the Grand Totaliz-
er is manually stored in this way before changing
the battery, no data will be lost.
