How to upgrade the firmware of Network
Step 1) Prepare a USB memory. Step 2) Extract and copy an update file to root directory on your USB memory. e.g.) A file which is unzipped is �NK.bin� Step 3) Unplug the power cord and insert the USB memory into the USB slot. Step 4) Press and hold the projector�s [MENU] and [RETURN] keys. Then plug in the power cord and turn on Main power switch. When the projector enters the firmware upgrade mode of Network, the buzzer beeps for 1 sec., [LAMP], [ON/STANDBY] and [TEMP] LED Blinks Red, Orange and Red in order. The firmware upgrade will take about 5 minutes. When it is completed, the state of projector will become standby mode. If projector doesn�t become standby mode, it means the firmware upgrade has failed. You need to try again. Step 5) Make sure of the F/W version. You can find it on the OSD menu of NETWORK input. (Press the NETWORK button and press the MENU button twice. You can see the version in the status display of Setting display (2) menu.) Step 6) Turn the projector off and take USB memory out.
