The GSE charger, when utilized for charging the FQM-
117 B-1 and FQM-117 C-1, system batteries (both
standard and fast charging) must be connected to a 110-
120 Vac power source.
When charging is complete, disconnect the equipment
from the charger to prevent discharge when the charger
is switched off.
