A-5 Battery Care/Maintenance
Guidelines for Using Batteries
It is recommended that you use the following guidelines
when using batteries:
 When installing or removing a battery pack, do not
touch or bend the battery connection terminals on
the calibrator.
 When installing or removing a battery pack, do not
short the terminals on the back of the battery.
Doing so will damage the battery pack and may
cause bodily injury.
 Dispose of unusable batteries as specified by local
regulations. Because NiCd batteries contain
hazardous chemicals and have the potential to
explode, do not use fire as a means of disposal.
You may return used batteries to Martel for
disposal.
Installing a Battery Pack
Use the following procedure to install a battery pack:
1. Before installing a battery pack, disconnect the
pack from any charging device.
2. Hold the battery pack at a slight angle to the
calibrator, then insert the two tabs of the pack into
the slots on the calibrator.
3. Press the top of the battery pack into the calibrator
and secure it by tightening the two captive screws
on the back of the battery pack.
CAUTION: Overtightening the screws may damage
the battery pack and the calibrator.
