Battery Swap Time

3.3.3 Battery Swap Time

Assuming the default power saving parameters and battery reserve level have not been altered, battery swap time is approximately 5 minutes—you will not lose data if the battery is replaced within this time frame.

To protect data, the safest place to store data is on a SD/MMC memory card or

externally to the device on a USB memory stick or on a PC.

To protect against data loss, the unit will automatically shut down with enough reserve in the main battery to last up to 99 hours, the default setting. (Refer to “Suspend Threshold” on page 137 for details about reserving battery power for data backup purposes.) Even when the hand-held shuts down, the backup battery continues to draw a trickle charge from the main battery to maintain the data stored in the unit until a new battery can be installed.

3.3.3.1Safely Swapping The Main Battery

There are a few steps you need to take to ensure that no data is lost during a battery swap. First, you need to make certain that the backup battery is holding at least 80% of its charge capacity. This information is displayed in the Battery tab.

•Tap on Settings and then on the Power icon. Tap on System>Battery and check the Backup battery gas gauge to determine the battery charge remaining.

If the backup battery charge capacity is less than 80%:

•Insert the WORKABOUT PRO in a docking station or cradle to top up the power supply before removing the main battery from the unit.

Important: Before opening the battery cover on your WORKABOUT PRO to remove the battery, you must turn off the hand-held. If the battery cover is opened while the hand-held is still powered on, the unit may reboot.

3.3.4 Charging The Battery

Batteries shipped from the factory are charged to approximately 40% of capacity. They must be fully charged prior to use.

Keep in mind also that, along with the main battery, the WORKABOUT PRO is equipped with an internal, backup battery that preserves data stored on the unit while the main battery is swapped.
