2.4.3 Handling cautions

ATING INSTRUCTIONS.
• Observe the following cautions.
- Be sure to disconnect the power cord from the AC power
source.
- The lamp remains quite hot after power off. Be sure to allow
plenty of time (30 minutes to 1 hour) to cool before proceed-
ing.
- The lamp can break if dropped or subjected to physical
shock.
- Use care not to directly touch or soil the lamp projecting
(glass) face.
• When installing the lamp unit, observe the interior projections
of the lamp cover are securely inserted into the holes of the
projector. Since the lamp cover projections engage the inter-
lock switch part of the protector circuit (normal operating state),
be sure the cover is properly positioned and secure with
screws.
• The replaced old lamp (depleted lamp unit) can be discarded
in the same manner as a fluorescent lamp. Check local ordi-
nances and dispose of the used lamp as prescribed.
2.4.4 Lamp use time reset
• Be sure to reset the Lamp use time after replacing the lamp
unit. Unless reset, the projector will cease operation (lamp will
not light) when 2000 hours are reached.
∗Conversely, reset the use time only after replacing the lamp.

CESSOR PWB ASS'Y and need to be reentered after replac-
ing the PROCESSOR PWB ASS'Y. Use the special software
and a personal computer to reenter the data. Afterwards, con-
firm the mode has been returned to that prior to board replace-
ment.
