CAUTION: There is a high risk of data loss from RAM if the backup battery is
not fully charged. This can happen if the main battery has been
drained and the unit is not connected to the AC adaptor. For this
reason, it is crucial that the backup battery is switched on before
charging the main battery for the first time.
Protective Screen Film
To protect the screen during shipping, the HT680's screen is covered with a
protective plastic film. You may remove it if required. The screen will be more
susceptible to scratching without the film, but can be read and used easier.
First Time Using the HT680
Pressing the Power ON/OFF Key
The Unitech HT680 welcome screen appears. The Windows CE screen will
appear shortly thereafter.
Align the Screen
When prompted, use the stylus to select the targets as they appear in order to
align the touch screen.
When you complete the procedure, press any key or press anywhere on the
touch screen to start up the WinCE system.
Adjusting Screen Brightness
To adjust the original default setting of the screen brightness, the backlight
setting will be required. Please refer to page 20 for the new setting procedure.
