Suspend Threshold

138 WORKABOUT PRO Hand-Held Computer With Windows Mobile 5.0 User Manual

6.21.6.1 Suspend Threshold And Estimated Battery Backup

The Estimated Battery Backup is the amount of battery power that is reserved to

protect data until a charged battery can be installed in the hand-held. When the main

battery capacity is depleted up to the Estimated Battery Backup reserve specified in

the Suspend Threshold tab, the hand-held shuts off automatically and uses the

reserve power to preserve the data stored on the WORKABOUT PRO. Once the

hand-held shuts down, it cannot be switched on until a fresh battery is installed, or

the unit is inserted in a docking station or cradle.

•Slide the Suspend Threshold button to the right to increase the battery

capacity reserved for backup purposes. Data will be preserved to a

maximum of 124 hours. The default value assigned for a standard

2000mAh battery is 99 hours.

•Slide the Suspend Threshold button to the left to decrease the power

reserved for backup purposes; this increases the hand-held’s operating time

– the amount of time the hand-held will operate before shutting down – but

reduces the power reserved for backup purposes to a minimum of 24 hours.

The backup battery draws a trickle charge from the reserved main battery power to

maintain the data even after the unit power is shut down. It will protect the data

stored in the WORKABOUT PRO while the main battery is swapped for a fully

charged one.

Important: Once the main battery is removed, the backup battery will pre-

serve the data stored on the WORKABOUT PRO for approxi-

mately 5 minutes. It is critical that you install a charged main

battery before this time elapses.
