Charging the Battery
Before using the device for the first time, charge the main battery until the green Charging/Notification light
emitting diode (LED) remains lit. To charge the device use a cable or a cradle with the appropriate power
supply. For information about the accessories available for the device see fAccessories for more
information.
The standard battery charges from fully depleted to 90% in approximately 3 hours. The extended battery
charges from fully depleted to 90% in approximately 4 hours.
NOTE: In many cases, the 90% charge provides plenty of charge for daily use.
To achieve the best fast charging results use only Zebra charging accessories and batteries. Charge
batteries at room temperature with the device in sleep mode.
Charge batteries in temperatures from 5°C to 40°C (41°F to 104°F). The device or accessory always
performs battery charging in a safe and intelligent manner. At higher temperatures (e.g. approximately
+37°C (+98°F)) the device or accessory may for brief periods of time alternately enable and disable battery
charging to keep the battery at acceptable temperatures. The device or accessory indicates when charging
is disabled due to abnormal temperatures via its LED and a notification appears on the display.
To charge the main battery:
1. Connect the charging accessory to the appropriate power source.
2. Insert the device into a cradle or attach to a cable. The device turns on and begins charging. The
Charging/Notification LED blinks amber while charging, then turns solid green when fully charged.
