Thermal Protector

When the temperature inside the projector becomes abnormally high, the STATUS indicator flashes red (0.5 seconds on/0.5 seconds off), the POWER indicator is a steady red, and at the same time the tem- perature protector operates and switches off the power of the projector.

Should this happen, please take the following actions.

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

2.Check the following matters and take the required measures.

When the projector is being used in a location that has a high ambient temperature, set it up again in a cool location. Check the outflow and intake holes and clean them if they are obstructed.

3.Wait about 60 minutes until the temperature of the projector drops.

If after having performed the above matters, the problem still has not been solved, please contact your store of purchase.
