4 Allegro 3 Rugged Handheld Owner’s Manual
Apply a Screen Protector (Optional)
The touchscreen is extremely scratch-resistant, so a screen
protector is not included with the Allegro 3. If you decide to
apply one, refer to the installation instructions included with
the screen protector for specic details.
Install the Battery Pack, SD Card, and Mini SIM Card
The Allegro 3 uses a rechargeable Li-Ion battery pack.
Install and charge the battery pack sing the instructions
that follow.
CAUTION: Always power off the handheld before removing
the battery. Failure to do so may cause loss of data or
damage to the handheld.
1. The battery compartment is accessed from the back of
the handheld. Loosen the four captive screws holding
the battery compartment door in place using a #1
Phillips screwdriver. Remove the door.
CAUTION: The Allegro 3 is not sealed against water and
dust when the battery door is not installed.
2. If you are using a micro SD card for additional memory
or a mini SIM card with the 3G Data Modem (optional),
you can install them now before you install the battery
pack, or at another time. See more details about these
cards later in this manual.
