Temperature Ranges for Charging the NiMH Battery Pack
The Field PC NiMH battery pack is charged most efficiently at
temperatures ranging between 10° to 20° C (50° to 68° F) when
the AC power adapter is used. The Field PC battery pack does
not charge outside of the range 0° to 40° C (32° to 104° F).

To properly use the alkaline battery holder, complete the
following steps:
