Charging the Main Battery
Before using the ET1 for the first time, charge the main battery until the Battery Charge light emitting diode
(LED) turns solid green (see Table 1-2 on page 1-6 for charge status indications). To charge the ET1, use a
cable or a cradle with the appropriate power supply. For information about the accessories available for the
ET1, see Chapter 9, Accessories.
The ET1 is equipped with a memory backup battery that automatically charges from the fully-charged main
battery. When using the ET1 for the first time, the backup battery requires approximately 40 hours to fully
charge. This is also true any time the backup battery is discharged, which occurs when the main battery is
removed for several hours. The backup battery retains random access memory (RAM) data in memory for at
least 15 minutes (at room temperature) when the ET1’s main battery is removed, when Battery Swap feature is
used. When the ET1 reaches a very low battery state, the combination of main battery and backup battery
retains RAM data in memory for at least 36 hours.
For cable and cradle setup and charging procedures refer to the ET1 Enterprise Tablet Integrator Guide.
