Note: Verify that the battery is installed prior to connecting the wall
charger. If both the wall charger is connected and the battery is
not installed, the handset will power cycle continuously and
prevent proper operation. Failure to unplug the wall charger
before you remove the battery, can cause the device to become
damaged.
Important! It is recommended you fully charge the battery before
using your device for the first time.
1. Connect the USB cable to the charging head.
2. Locate the Charger/Accessory jack.
3. Insert the USB cable into the device’s Charger/Accessory jack.
4. Plug the charging head into a standard AC power outlet. The
device turns on with the screen locked and indicates both its
charge state and percent of charge.
Warning! While the device is charging, if the touch screen does not
function due to an unstable power supply unplug the USB
power adapter from the power outlet or unplug the USB
cable from the device.
