Batteries
The power consumption of the Allegro CE is very efficient. The Auto
Suspend and Power Management features help to conserve power.
Maintaining the battery pack and backup supply is simple.
There are two types of batteries and a backup capacitor associated
with the Allegro:
❏ NiMH battery pack
❏ Battery holder for three alkaline cells (optional accessory)
❏ Super capacitor that serves as the RAM backup (maintains the
RAM while you change the battery pack)

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 along
with the Allegro but is not installed at the factory. When you receive
the Allegro, you must install and then charge the battery pack. To do
this, complete the following steps:
1) Push up on the sliding latches on the sides of the Allegro to open
the battery compartment door .
2) Place the NiMH battery pack in the left side of the battery
compartment, push down, and slide it all the way to the right.
3) Push the battery door closed until each latch clicks into place.
