Fig. 4 Upgrade screen
When the user clicks [Flash Write Mode], the Network block enters the upgrade ready state, and disables
the Web-browser not to be displayed. (The Web-browser displays an error indication.)
If the PC does not issue the upgrade requirement command for 15 minutes or more, the Network block
automatically exits the upgrade standby state and returns to the normal state after it is rebooted.
If version upgrade is executed, the Network block remains in the upgrade standby state unless the AC
power of the projector is unplugged.

The upgrade requirement is issued at the moment when the [Update] button is clicked in the Firmware
Updater, which is described later.
The upgrade requirement is not issued if simply the Firmware Updater is launched.
The Update screen will open. Then click [Flash Write Mode] .
