1.5. TEMPERATURE DETECTION FOR THE LAMP UNIT
This projector has bimetal (Thermostat) contacting the lamp unit to protect the lamp. If the
temperature of the lamp exceeds 120 °C, the bimetal will operate to turn off the power.
The installed position of the bimetal is shown in the illustration.
To recover the bimetal from its off state, press the protrusion of the bimetal unit until hear click.
2. PREVENTION OF ELECTROSTATIC DISCHARGE
(ESD) TO ELECTROSTATICALLY SENSITIVE (ES)
DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such
components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical
ES devices are integrated circuits and some field-effect transistorsandsemiconductor "chip"
components. The following techniques should be used to help reduce the incidence of
component damage caused by electro static discharge (ESD).
1. Immediately before handling any semiconductor component or
semiconductor-equipped assembly, drain off any ESD on your
body by touching a known earth ground. Alternatively, obtain and
wear a commercially available discharging ESD wrist
strap,whichshould be removed for potential shock reasons prior
