This screen allows the user to adjust the LCD Backlight brightness, LCD Contrast, and LCD
Saturation. In addition, users may configure the TV OUT mode (NTSC or PAL) here.
Note: After setting TV out to an external source, the phone LCD screen will black out. Please
make sure that you have plugged in the external output source before selecting this option. To
return the display to the LCD menu, log into the web browser interface and disable TV Out in
“Device Manager” -> “TV Output”. Otherwise, you will need to reboot the phone to enable the
LCD screen.

There are three tabs on the Maintenance setting screen: Upgrade, Factory Functions and
Debug. Users can configure the upgrade mode and firmware server IP address/URL on the
upgrade tab. Once this is saved, users can choose to reboot the phone to upgrade the
firmware. Similarly, a factory reset can be performed on the Factory Functions tab. A more
detailed step-by-step guide will be given in the “Restore to Factory Default Settings” section
that follows.
