16 Allegro 3 Rugged Handheld Owner’s Manual
Powering O for Long-Term Storage
To power off the Allegro 3 for long-term storage (two weeks
or more), follow these steps:
1. Power off the Allegro 3 as described in the previous
section.
2. Press and hold the power button for 20 seconds. This
disconnects the batteries from the system.
3. Take out the battery pack and store it in a cool, dry
location.
4. When you are ready to power on the Allegro 3, replace
the battery pack. Plug in the AC wall charger and
connect it to the Allegro 3 BEFORE you power it on. Hold
down the power button for 2-3 seconds until the Lock
screen is shown.
How to Handle a Locked Up Unit
If the Allegro 3 is completely stuck and won’t respond,
hold the power key down for 2 to 3 seconds to see if the
menu with the “Power off” option appears, and select that
operation. If that doesn’t work, hold the power key down for
10 seconds. This causes a hardware shut off. Press the power
key again to power it on.
If 10 seconds doesn’t work, hold the power button down
for 20 seconds. The battery pack is forced to electrically
disconnect from the Allegro 3, causing a complete shut
down. The handheld cannot be powered on again until it is
plugged in with the AC wall charger. Keep this in mind if you
are in the eld.
CAUTION: Forcing a shut-down while the unit is running can
cause damage to the device. NEVER do this to power off an
Allegro 3 in normal circumstances.
Recovery or Factory Reset
The Allegro 3 can be restored to the factory state with all
user data removed from the unit.
In order to perform the Factory Reset, go to Settings >
Backup & Reset > Factory Data Reset. You are presented
with a screen describing all of the data that will be removed
