Thermal protector
(SW905)
Thermal protector (SW905)
There is the thermal protector (SW905) inside of the pro-
jector to detect the internal temperature rising abnormally.
When the internal temperature reaches near 115˚C, the ther-
mal protector cuts off the current supplied to the power sup-
ply circuit.
To reset the thermostat, disconnect the AC cord and leave
the projector at the normal surrounding temperature for
about 45 minutes. The thermostat will automatically reset
when the internal temperature becomes less than 75
˚C
