3.1 Preparing The Warrington Hand-Held For Operation
3.1.1 The Battery
The Warrington is powered with a 3000 mAh Lithium Ion battery pack – Model No.
WA3006.
3.1.1.1 Charging The Main Battery
Battery packs shipped from the factory are charged to approximately 40% and must be fully
charged prior to use. Batteries can be charged using a variety of chargers and docking sta-
tions along with a Warrington internal charger. When using the internal charger, a suitable
power source is required. All chargers and docking stations are described in Chapter 7: “Pe-
ripheral Devices & Accessories” beginning on page 184.
3.1.2 The Super Capacitor
An onboard super capacitor provides up to 10 minutes of suspend mode backup power to the
Warrington to give you time to swap in a new battery; all unnecessary draws on power such
as the display and CPU are shut down to preserve power.
If the battery pack reaches its Suspend Threshold (refer to “Suspend Threshold” on
page 102) and the hand-held shuts down, the super capacitor will protect the data stored in
the unit until a charged battery pack is installed.
Warning: Before charging the battery, it is critical that you review the battery safety
guidelines in Chapter 1: “Approvals & Safety Summary”.
Important: Before opening the battery cover on your Warrington, press [FN/BLUE]
[ENTER] to turn off the hand-held. Removing the battery while the unit is
running may cause the hand-held to reboot.
Note: If you are powering up a new unit, a warning message may appear on the screen
indicating that the backup battery capacity is low. To recharge the internal battery,
you must fully charge the Warrington with the main battery installed in the unit.
Important: When you initially power up the hand-held, leave the battery in the unit for a
minimum of 2 minutes to allow the super capacitor to reach full capacity.
