Thermal protector

When the temperature inside the projector becomes abnormally high, the LED indicator flashes red (0.5 seconds on/0.5 seconds off) the Standby indicator is a steady red, and at the same time the temperature protector operates and switches off the power of the projector. If this happens, please follow the steps below:

1.Switch off the power and disconnected the power plug from the wall outlet.

2.Check the temperature of the room. If the projector is being used in a location with a high ambient temperature, set it up in a cooler location.

3.Check the vent openings to make sure that they are all clear. Clean the vent openings if they are obstructed.

4.Wait at least 1 hour until the temperature of the projector drops, then plug it in again.

5.If you are still having the same problem, please contact your retailer.
