Backup Battery; Handling Batteries Safely - Honeywell HX3 User Manual

When the main battery is disconnected the device enters Critical Suspend state, the HX3 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 HX3 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 HX3 startup completes,
and Bluetooth relationships establish or reestablish.
If the backup battery depletes before a fully charged main battery can be inserted, the HX3 will turn Off.

Backup Battery

The HX3 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 HX3 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 HX3, its features and any operating applications.
The backup battery has a minimum service life of two years. The backup battery is not user-serviceable.
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.

Handling Batteries Safely

Never dispose of a battery in a fire. This may cause an explosion.
• Do not replace individual cells in a battery pack.
• Do not attempt to pry open the battery pack shell.
• Be careful when handling any battery. If a battery is broken or shows signs of leakage do not attempt to charge it.
Dispose of it using proper procedures.
• Nickel-based cells contain a chemical solution which burns skin, eyes, etc. Leakage from cells is the only possible way
for such exposure to occur. In this event, rinse the affected area thoroughly with water. If the solution contacts the eyes,
get immediate medical attention.
• NiCd and Li-Ion batteries are capable of delivering high currents when accidentally shorted. Accidental shorting can
occur when contact is made with jewelry, metal surfaces, conductive tools, etc., making the objects very hot. Never place
a battery in a pocket or case with keys, coins, or other metal objects.
