Getting Started 1 - 7
Charging the Battery
Charging the Main Battery and Memory Backup Battery
Before using the wearable terminal for the first time, charge the main battery until the amber Charge Status
LED remains lit (see
Table 1-2 on page 1-7 for charge status indications).
The wearable terminal is equipped with a memory backup battery which automatically charges from the main
battery whether or not the wearable terminal is operating or is in suspend mode. The memory backup battery
retains data in memory for at least 30 minutes when the wearable terminal's main battery is removed or fully
discharged. When the wearable terminal is used for the first time or after the memory backup battery has fully
discharged, the memory backup battery requires approximately 15 hours to fully charge. Do not remove the
main battery from the wearable terminal for 15 hours to ensure that the memory backup battery fully charges. If
the main battery is removed from the wearable terminal or the main battery is fully discharged, the memory
backup battery completely discharges in several hours.
When the wearable terminal reaches a very low battery state, the combination of main battery and backup
battery retains data in memory for at least 24 hours.
Charge the wearable terminal with an installed main battery using either the Single Slot USB cradle or the Four
Slot Ethernet cradle.
To charge the main battery:
1.
Ensure the cradle used to charge the main battery is connected to the appropriate power source.
2.
Insert the wearable terminal into a cradle.
3.
The wearable terminal starts to charge automatically. The amber Charge Status LED lights to indicate the
charge status. See
Table 1-2 for charging indications. The standard capacity battery fully charges in less
than four hours and the extended battery fully charges in less than eight hours.
CAUTION Ensure that you follow the guidelines for battery safety described in Battery Safety Guidelines on page
6-3 .
NOTE Do not remove the main battery within the first 15 hours of use. If the main battery is removed before the
backup battery is fully charged, data may be lost.
