four hours. The mobile computer can be charged using a cradle, the CAM, or the MSR with the appropriate power
supply.
The mobile computer is also equipped with a memory backup battery which automatically charges from the main
battery whether or not the mobile computer is operating or is in suspend mode. The memory backup battery retains
data in memory for at least 30 minutes when the mobile computer's main battery is removed or fully discharged.
When the mobile computer 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
mobile computer for 15 hours to ensure that the memory backup battery fully charges. If the main battery is
removed from the mobile computer or the main battery is fully discharged, the memory backup battery completely
discharges in several hours.
When the main battery 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.
