WT4070/90 Wearable Terminal User Guide

Before using the wearable terminal for the first time, charge the main battery until the amber Charge Status LED 
remains lit (see 

 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:

Ensure the cradle used to charge the main battery is connected to the appropriate power source.

Insert the wearable terminal into a cradle.

The wearable terminal starts to charge automatically. The amber Charge Status LED lights to indicate the 
charge status. See 

 for charging indications. The standard capacity battery fully charges in less than 

four hours.

Ensure that you follow the guidelines for battery safety described in 

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.
