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). Check that the POWER indicator
light on the projector lights orange after power
has been applied.
2.
Slide the lens cap open. If it is closed, it could
become deformed due to the heat produced by
the projection lamp.
3.
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 39
for
details.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 seconds
before energizing the lamp.
4.
If you are prompted for a password, press the arrow keys to enter a six digit password.
See
"Utilizing the password function" on page 26
for details.
5.
Switch all of the connected equipment on.
6.
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 message 'No Signal' 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 28
for details.
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 58
for details.
