Operation
Starting up the projector
1. Plug the power cord into the projector and into a wall socket.
Turn on the wall socket switch (where fitted).
Please use the original accessories (e.g. power cable) only with
the device to avoid possible dangers such as electric shock and
fire.
2. Press the main power switch to the I position.
Check that the POWER indicator light on the projector lights
orange after power has been applied.
3. Remove the lens cap.
If it is closed, it could become deformed due to the heat
produced by the projection lamp.
4. Press POWER on the projector or remote control to start
the projector. As soon as the lamp lights up, a "Power On Tone"
will be heard. The POWER indicator light flashes green and
stays green when the projector is on.
The start up procedure takes about 30 seconds. In the later stage
of start up, a startup logo is projected.
(If necessary) Rotate the focus ring to adjust the image
clearness.
To turn of the ring tone, see "Turning off the Power on/off ring
tone" on page 37 for details.
5. If you are prompted for a password, press the arrow keys to
enter a six digit password. See "Utilizing the password function"
on page 24 for details.
6. Switch all of the connected equipment on.
7. The projector will start to search for input signals. The current
input signal being scanned displays in the upper left corner of
the screen. If the projector doesn't detect a valid signal, the 'No
Signal' message will continue displaying until an input signal is
found.
You can also press SOURCE on the projector or remote control
to select your desired input signal. See "Switching input signal"
on page 26 for details.
If the projector is still hot from
previous activity, it will run the
cooling fans for approximately
90 seconds before energizing
the lamp.

If the frequency/resolution of
the input signal exceeds the
projector's operating range, you
will see the message 'Out of
Range' displayed on a blank
screen. Please change to an
input signal which is compatible
with the projector's resolution
or set the input signal to a lower
setting. See "Timing chart" on
page 51 for details.
