NOTE: After setting TV out to an external source, the phone LCD screen will black out. Please make

sure to plug 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, the phone will need to reboot to enable the LCD screen.

MAINTENANCE

There are four tabs on the Maintenance setting screen under MENU->Settings->Maintenance:

Upgrade, Factory Functions, Debug and Backup. 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.
