7.Software Upgrade
This product is based on a well developed operation system. We design it very convenient to upgrade its
operation system. We called it “USB Power-OFF upgrade”.
We need to (or can try) upgrade software in conditions when:
1. Display defeat;
2. Uncontrolled power off;
3. USB player defeat;
4. Sound defeat;
5. Other defeats.
USB Software Upgrade Step:
1. Copy the software file to USB memory disk. Don’t change the file name or the system may not
recognize successfully.
2. Enter TV Factory Menu and note down the software version. (For detail find in “Factory Manual for
user”.)
3. Pull out the AC cord and insert your USB memory disk.
4. Insert AC power cord, the standby LED will turn on and off.
5. Don’t pull the AC cord out until the standby LED flickering fast or the TV set turning on
automatically.
6. Pull out the USB memory disk and turn on the TV set, enter the Factory Menu and record the new
software version.
