Charging the Battery

Before using the TC20 for the first time, charge the internal battery until the green Charging/Notification light emitting diode (LED) remains lit. To charge the TC20 use a cradle with the appropriate power supply or USB cable and power supply. For information about the accessories available for the TC20 see Accessories for more information.
The internal battery charges from fully depleted to 90% in approximately four hours and from fully depleted to 100% in approximately five hours.
NOTE In many cases the 90% charge provides plenty of charge for daily use. A full 100% charge lasts for
approximately 10 hours of use.
Use only Zebra charging accessories and batteries. Charge batteries at room temperature with the TC20 in sleep mode.
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). The TC20 or accessory always performs battery charging in a safe and intelligent manner. At higher temperatures (e.g. approximately +37°C (+98°F)) the TC20 or accessory may for small periods of time alternately enable and disable battery charging to keep the battery at acceptable temperatures. The TC20 or accessory indicates when charging is disabled due to abnormal temperatures via its LED and a notification appears on the display.
To charge the internal battery:
1. Connect the charging accessory to the appropriate power source.
2. Insert the TC20 into a cradle or attach to a USB cable. The TC20 turns on and begins charging. The
Charging/Notification LED blinks amber while charging, then turns solid green when fully charged.
