display system will short-circuit and probably go up in flames.

Check that the operating voltage of the display system is identical with the voltage

of your local power supply.

When Display is operating

WARNING

Do not place anything heavy upon power cords or signal cables.

Ensure all the cable connectors and the power plugs are connected securely in

place before turning on the display system.

For the first time operating device or long-time stored device, the device may not

work normally due to the low temperature. Please use some proper tools to warm
up the main board, e.g. heater. After the warm up, you can turn on the device.

If the Input electrical voltage is not stable, please install AVR beside the Display to

prevent the display shutdown.

Please don’t decorate the base to keep better air-circulation of the air condition for

heat dissipation.

Please keep the air condition’s surrounding area (30cm around base) clear to have

better heat dissipation.

two days.
