Remove the batteries and verify that the battery compartment and
electrical contacts are clean. Insert fresh batteries (alkaline or
fully-charged Ni-Cad) according to the polarity (+/-) markings
and replace the cover.
3. Recharging Batteries
Note
The GX-82A charger detects the installed battery type and
will not charge alkaline cells, to prevent damage to the
instrument. Only Ni-Cad cells will charge properly with the
GX-82A charger.
Rechargeable batteries may be recharged inside the GX-82A in a
non-hazardous location. Turn the instrument off, connect the
charger to the charger jack, and plug the charger into a 115 V AC
outlet. Full charge requires approximately 12 hours.
