E-EQ-HX2RG-B HX2 Reference Guide
Battery Hotswapping
Important: When the backup battery power is Low or Very Low ( | 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 Voxware-enabled applications complete, Wavelink
Avalanche management of the HX2 startup completes, and Bluetooth relationships establish or re-
establish.
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 replaced by
LXE.
The backup battery can be discharged, recharged and conditioned using a CE Control Panel
applet. Tap
| Settings | Control Panel | Battery then tap the Discharge button.
