Battery
The rechargeable Lithium-ion battery is installed in the device. Plug the USB charging cable into the
USB port to recharge the battery. The charging LED in the right top corner of the device will illuminate
solid red while the battery is charging and will turn off once the battery is fully charged. The battery
charge time is approximately 3.5 hours from empty. The beltpack may be used while charging, but
doing so may lengthen battery charge time.
