Basic operation (continued)
• To avoid permanently imprinting a fi xed image
onto your projector, please do not display the
same stationary images for long period.
6. Adjust the image size by turning the zoom ring.
• If necessary, adjust the focus and zoom again.
When fi ne streaks are seen on projected
images
This is due to interference with the screen surface and
is not a malfunction.
Replace the screen or displace the focus a little.
Power-off
Use the following procedure to turn off the projector.
The lamp may deteriorate if the projector is powered
off and on repeatedly within 30 minutes after the lamp
is lighted.
1. Press the POWER button on the control panel or
the STANDBY button on the remote control.
• The message " POWER OFF? YES : PRESS
AGAIN" appears on the screen.
• To cancel, press any button except the POWER
button.
(Some buttons on the remote control don't
function for cancel.)
2. Press the POWER button on the control panel or
the STANDBY button on the remote control within
10 seconds again.
• The lamp will go out and the STATUS indicator
will start blinking.
• Though the lamp goes out at this second press
of the POWER button (or STANDBY button), the
air outlet fans continue operating for one minute
to cool down the lamp. The STATUS indicator
will stop blinking.
• After stopping the air outlet fans, if the
temperature inside the set is still high, the
temperature sensor detects it and then the air
outlet fans may start again.
3. Unplug the power cord.
• The POWER indicator will go out.
• If the power cord should be unplugged
accidentally while either the air inlet fan or the
air outlet fans are operating or the lamp is on,
allow the projector to cool down for 10 minutes
with the power off. To light the lamp again, press
the POWER button (or ON button). If the lamp
doesn't light up immediately, repeat pressing
the POWER button (or ON button) two or three
times. If it should still fail to light up, replace the
lamp.
Important:
• When storing the projector in the carrying case, the
lens should face up.
Before carrying the projector, rotate the focus ring
and zoom ring to adjust the lens to the shortest.
This prevents the possible damages of the lens.
Instant Shut Down
You can turn off this projector just by unplugging the
power cord without pressing the POWER button.
• Don't shut down the projector while the STATUS
indicator is blinking after the lamp lights up
because the lamp's life may be shortened.
• Don't turn the projector back on right after shutting
it down because the lamp's life may be shortened.
(Wait about 10 minutes before turning the projector
back on.)
• Before shutting down the projector, be sure to close
the menu screen. If you shut down the projector
without closing the menu, the setting data of the
menu may not be saved.
• If you shut down the projector while controlling
the projector using the network function, the
application software such as Projector- View may
fail. For details, see "User Manual of LAN Control
Utility" contained in the CD-ROM.
