Batteries
Batteries are the key power source the Allegro uses while you are in
the fi eld collecting data. When collecting data, the Allegro performs
with effi cient power consumption.
The Allegro CX uses an Auto Suspend power management feature
to help conserve power. A battery status icon is displayed in the task
bar of the Allegro indicating the amount of power (as a percentage)
that is left in the battery pack. This battery status icon helps you
maintain the battery pack by keeping you informed of the charge
level and warning you when the charge is getting low and needs to
be charged or replaced.
There are three types of batteries and a backup capacitor associated
with the Allegro power supply:
NiMH battery pack
Alkaline battery holder (an optional accessory using three
alkaline cells)
Lithium CMOS battery to power the real time clock
Super capacitor designed to maintain the RAM while you change
the battery pack
Main Power Source
The Allegro is powered by a rechargeable nickel metal hydride
(NiMH) battery pack. The battery compartment is accessed through
a door in the back of the case. The NiMH battery pack is shipped
with the Allegro but it is not installed at the factory.
