ENGLISH - 9
Important
Information
Avoid setting up in places which are subject to
vibration or shocks.
The internal parts can be damaged, which may cause
malfunctions or accidents.
Avoid setting up in places which are subject to
sudden temperature changes, such as near an air
conditioner or lighting equipment.
The life of the lamp may be shortened or the projector
may be turned off. See “TEMP indicator” on page 45.
Do not set up the projector near high-voltage power
lines or near motors.
The projector may be subject to electromagnetic
interference.
If installing the projector to the ceiling, ask a
qualified technician or an Authorized Service Center
to carry out all installation work.
You will need to purchase the separate installation kit
(Model No. ET-PKE2000, ET-PKE1000S).
Furthermore, all installation work should only be
carried out by a qualified technician.
See “Ceiling mount bracket safeguards” on page 56
for the safety cable installation.
If using this projector at high elevations 1 400 -
2 700 m (4 593 - 8 858 ft) sea level, set the HIGH
ALTITUDE MODE to ON. See “HIGH ALTITUDE
MODE” on page 44.
Failure to observe this may result in malfunctions or
the life of the lamp or the other components may be
shortened.
In order to get the best picture quality
Draw curtains or blinds over any windows and turn off
any lights near the screen to prevent outside light or
light from indoor lamps from shining onto the screen.
Do not touch the surfaces of the lens with your bare
hands.
If the surface of the lens becomes dirty from
fingerprints or anything else, this will be magnified
and projected onto the screen. Moreover, when not
using the projector, attach the lens cover.
Liquid crystal panel
Do not project the same image for long periods of
time, as this may remain as an afterimage on the
liquid crystal panel. Display the white screen test
pattern for more than an hour to remove it. See
“ZOOM/FOCUS” on page 40.
The liquid crystal panel of the projector is built with
very high precision technology to provide fine picture
details. Occasionally, a few stuck pixels may appear
on the screen as fixed points of blue, green or red. It
is recommended to switch off the projector once and
try after 1 hour later again. Please note that this does
not affect the performance of your LCD.
The projector has a high pressure mercury lamp and
that is characterized as follows.
The brightness of the lamp depends on the duration
of use.
The lamp may explode or shorten the lamp life by
shocks or chipping damage.
The lamp may explode only occasionally after using
the projector.
The lamp may explode if using the projector after the
instructed lamp replacement timing.
When the lamp exploded, it emits the internal smoke-
like gas.
The lamp life depends on individual lamp
characteristics, usage condition and the installation
environment. Especially the consecutive use of the
projector for more than 10 hours, or the frequent
switching on or off may greatly affect on the lamp life.
Optical components
If you use the projector consecutively 6 hours every
day, the optical components may need to be replaced
in less than 1 year.
