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.
Note: If the charger is incorrectly connected, damage to the
accessory port will occur therefore voiding the phone's
warranty.
5. When charging is finished, first unplug the charger's
power plug from the AC wall outlet, then disconnect
the charger's connector from the phone.
Important! If your handset has a touch screen display, please
note that a touch screen responds best to a light
touch from the pad of your finger or a non-metallic
stylus. Using excessive force or a metallic object
when pressing on the touch screen may damage
the tempered glass surface and void the warranty.
For more information, refer to "Standard Limited
Warranty" on page 308.
