Charging the Battery
Before using your terminal for the first time, charge the main
battery in the terminal for approximately 2 1/2 hours, using a
cradle or the serial charging cable.The larger capacity battery
charges in approximately 5 hours.
Your terminal is equipped with a memory backup battery which
automatically charges from the fully-charged main battery. This
backup battery retains data in memory for 20 minutes when the
terminal’s battery is removed, and takes about 24 hours to charge
when you first use your terminal.
Note: If the main battery is removed before the backup bat-
tery is fully charged, data may be lost. For this reason,
DO NOT remove the battery within the first 24 hours of
use.
