BATTERY BACK-UP MODULE (OPTIONAL)
This optional module is a field-installable assembly that provides power to operate the MT 5500
for up to twenty (20) hours on a fully charged battery. System software includes an alarm feature
that alerts the operator to a low-battery condition. This ensures that the unit continues to operate
at its peak performance level.
This module includes two 12v batteries and charging circuitry that comprise the Optional Battery
Pack. This module has a battery-monitoring circuit which will charge the battery within 12 hours
and will switch to trickle-charge to maintain a fully charged condition without damaging the batter-
ies.
