Note: Maintenance should be performed by qualified personnel

Note: The printed circuit board of the instrument is connected to
the battery pack even if the power is turned off. Therefore, it is
very important to disconnect the battery pack before servicing or

A fully charged battery runs the FMC2000 for up to 15 hours
continuously. The charging time is less than 8 hours for a fully
discharged battery. If the 12-volt lead-acid battery is old and does
not hold a charge, replace it with a new one, part number 500-
0132-000. Be sure to observe the "+" and "-" polarity orientation
when connecting the battery.
