Thermal protectors (SW902)

There are the thermal protector (SW902) inside of the projector to detect
the lamp surrounding temperature rising abnormally. When the temperature
reaches near 115˚C, the thermal protector cuts off the current supplied to the
power supply circuit.
To reset the thermal protection function, disconnect the AC cord and leave
the projector at the normal surrounding temperature for about 45 minutes.
The thermal protectors will automatically reset when the internal temperature
becomes normal (less than 75˚C).
