Suspend Threshold and Estimated Battery Backup

5.26.6 Suspend Threshold and Estimated Battery Backup

The Estimated Battery Backup is the amount of battery power that has been reserved or set
aside to protect data until a fully charged battery can be installed in the EP10. When the
battery capacity is depleted up to the Estimated Battery Backup reserve specified in the
Suspend Threshold tab, the EP10 shuts off automatically and uses the reserve power to pre-
serve the data stored on the EP10. Once the EP10 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.
• Slide the Suspend Threshold button to the left to decrease the power reserved for
backup purposes; this increases the EP10's operating time – the amount of time the
EP10 will operate before shutting down – but reduces the power reserved for backup
purposes to a minimum of 24 hours.
Internal super-capacitors will protect the data stored in the EP10 while the depleted battery
is swapped for a fully charged one.
Important: Once the battery is removed, the super-capacitors will preserve the data
