Do not look into the lens!
Be extremely careful not to look into the projection lens when the
LitePro is turned on. The bright light may harm your eyes. Be
especially careful to keep children from looking into the lens.
Turning projector on and off
Allow the projector to warm up for three minutes before turning
it off; allow the projector to cool down for three minutes before
turning it back on. Repeatedly turning the projector on and off
without waiting three minutes may cause the lamp to explode.
Power source
Use only a three-wire grounding type power source. The nominal
power source should not exceed 240 volts rms between the sup-
ply conductors or between either conductor and the ground.
Power cord
Use only the power cord that was shipped with the LitePro.
Although other power cords might be similar in appearance, they
have not been safety-tested with the 610 or 620. Do not use a
power cord if it has become damaged or frayed. Contact your In
Focus dealer or call In Focus if you need to replace your power
cord.
CAUTION: Be sure to replace
the projection bulb when the lamp
monitor light comes on as
described on page 41. If the lamp
remains in use too long, there is a
danger of bulb explosion. If this
happens, your LitePro will be
severely damaged.
Grounding
The projector is grounded through the grounding conductor on
the power cord. To avoid electric shock, plug the power cord into
a properly wired receptacle. Do not defeat the purpose of the
grounding-type plug.
Lamp
To avoid overheating and unacceptable image quality, replace
the projection lamp with a lamp of the specified type. Refer to
page 52 for lamp specifications and to page 41 for instructions on
replacing the lamp.
