Battery Charging
When less than 3 hours of operating time remain in Sensing Mode, the
WorkForce® Power LED will blink Red and the plug icon will be displayed
on the Icon Line of the display. The power-on tones are not emitted when
WorkForce® has a low battery. When audio is enabled, low battery is also
indicated by a double chirp sound once every fi ve minutes.
Warning:
There are no audible low battery sounds with audio tones disabled.
When low battery is indicated, less than 3 hours of operating time remain
and the battery should be charged immediately.
With the 120VAC charger provided, recharge time is approximately
3 hours from a low battery warning and 4 hours for a dead battery.
Typical operation time between recharging is approximately 40 hours in
Sensing Mode or approximately 24 hours when GPS is enabled.
An optional 12VDC charging adapter is available.
NOTE: Charging via computer USB port may take longer.
Plug the charger into an outlet. It takes approximately 10 seconds for the
unit to detect a charger connection and begin to show charging status.
Charging status is displayed on the side LED status bar 1-4. This battery
charge status will be indicated by the number of blinking status bar LEDs.
