Maintenance - Grandstream Networks GXV3140 Application Manual

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.

• 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.
The Factory Functions page provides some testing diagnostics for the LCD, camera and audio on the
GXV3140. (See figure below)
