Batteries
A set of four “AA” alkaline batteries are provided. To
install them in the unit, loosen the two screws on the
battery cover and follow the placement diagram in the
bottom of the battery compartment. The unit will operate
for about 25 hours of continuous use ( no backlite ) on a
fresh set of alkaline batteries. You can also install ni-cad
rechargeable batteries that have been charged in a separate
user provided charger.
There is a battery gauge on the main power on screen. See
page 6 for information on this gauge. When the batteries
drop to 4V, an X appears on the gauge indicating you
should change your batteries as soon as possible. The unit
won’t operate when the batteries drop below 3.7V.
Don’t install used batteries in the unit. If one battery in the
pack is discharged more than the others, it will effect the
operation of the battery gauge and could cause the unit to
switch off without the normal low battery warnings.
