mobile computer can be charged using a cradle, the CAM with a charging cable, or the MSR with the appropriate
power supply.
The mobile computer is equipped with a memory backup battery which automatically charges from the
fully-charged main battery. When the mobile computer is used for the first time, the backup battery requires
approximately 15 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 data in memory for at least 30
minutes when the mobile computer's main battery is removed. When the mobile computer reaches a very low
battery state, the combination of main battery and backup battery retains data in memory for at least 72 hours.
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.
