Battery Hotswapping
Important: When the backup battery power is Low or Very Low (Start > Settings > Control Panel > Power > Battery tab)
dock the HX2 in a powered docking cradle before replacing the battery pack.
When the main battery power level is low, the HX2 will signal the user with the low battery warning indicator (the Status LED
remains a steady red) that continues until the main battery is replaced, the battery completely depletes, or external power is
applied to the HX2 using a powered cradle.
You can replace the main battery by first placing the device in Suspend Mode then removing the discharged main battery and
tethering a charged main battery within a five minute time limit (or before the backup battery depletes).
When the main battery is disconnected the device enters Critical Suspend state, the HX2 remains in Suspend mode, the
display is turned off and the backup battery continues to power the unit for at least five minutes. Though data is retained, the
HX2 cannot be used until a charged main battery pack is connected. After tethering the full battery, press the Power key.
Full operational recovery from Suspend can take several seconds while the wireless client connects to the network,
authorization for voice-enabled applications complete, Wavelink Avalanche management of the HX2 startup completes, and
Bluetooth relationships establish or reestablish.
If the backup battery depletes before a fully charged main battery can be inserted, the HX2 will turn Off.
Low Battery Warning
It is recommended that the main battery pack be removed and replaced when its energy depletes. When the main battery Low
Battery Warning appears (the Status LED remains a steady red) perform an orderly shut down, minimizing the operation of any
installed devices and insuring any information is saved that should be saved.
Note: Once you receive the main battery Low Battery Warning, you have approximately 5 minutes to perform an orderly
shutdown and replace the main battery pack before the device powers off. The Low Battery Warning will transition the
mobile device to Suspend before the device powers off.
Backup Battery
The HX2 has a backup battery that is designed to provide limited-duration electrical power in the event of main battery failure.
The backup battery is a 50 mAh Nickel Cadmium (NiCd) battery that is factory installed in the unit. The energy needed to
maintain the backup battery near full charge at all times comes from the HX2 main battery.
It takes several hours of operation before the backup battery is capable of supporting the operation of the mobile device. The
duration of backup battery life is dependent upon operation of the HX2, its features and any operating applications.
The backup battery has a minimum service life of two years. The backup battery is not user-serviceable. Contact Technical
Assistance for backup battery replacement.
The backup battery can be discharged, recharged and conditioned using a CE Control Panel applet. Tap Start > Settings >
Control Panel > Battery then tap the Discharge button.
