Battery HotswappingBattery HotswappingImportant: When the backup battery power is Low or Very Low (Start | Settings | Control Panel | Power | Battery tab) dock the<strong>HX2</strong> in a powered docking cradle before replacing the battery pack.When the main battery power level is low, the <strong>HX2</strong> will signal the user with the low battery warning indicator (the Status LEDremains a steady red) that continues until the main battery is replaced, the battery completely depletes, or external power isapplied to the <strong>HX2</strong> using a powered cradle.You can replace the main battery by first placing the device in Suspend Mode then removing the discharged main battery andtethering 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 <strong>HX2</strong> remains in Suspend mode, thedisplay is turned off and the backup battery continues to power the unit for at least five minutes. Though data is retained, the<strong>HX2</strong> 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 <strong>HX2</strong> startup completes,and Bluetooth relationships establish or reestablish.If the backup battery depletes before a fully charged main battery can be inserted, the <strong>HX2</strong> will turn Off.Low Battery WarningIt is recommended that the main battery pack be removed and replaced when its energy depletes. When the main battery LowBattery Warning appears (the Status LED remains a steady red) perform an orderly shut down, minimizing the operation of anyinstalled 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 orderlyshutdown and replace the main battery pack before the device powers off. The Low Battery Warning will transition themobile device to Suspend before the device powers off.Backup BatteryThe <strong>HX2</strong> 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 tomaintain the backup battery near full charge at all times comes from the <strong>HX2</strong> main battery.It takes several hours of operation before the backup battery is capable of supporting the operation of the mobile device. Theduration of backup battery life is dependent upon operation of the <strong>HX2</strong>, 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 Start | Settings |Control Panel | Battery then tap the Discharge button.E-EQ-<strong>HX2</strong>RG-M [ 26 ] <strong>HX2</strong> <strong>Reference</strong> <strong>Guide</strong>
