5. OPERATION
This section describes how to select a computer or video source, ad-
just the picture and sound, edit a signal and adjust all other settings
and adjustments for proper projector set-up.
General Controls
Before you turn on the projector ensure that the computer or video source
is turned on and that the lens cap is removed.
1. Turn On The ProjectorPlug the supplied power cable into the AC outlet. The main power
switch is on the rear panel of the projector. By turning this switch on,
the projector will go into its standby mode and the POWER indicator
will glow orange. Only after you press the POWER ON button on
the remote control or projector cabinet will the POWER indicator
turn to green and the projector will fully turn on.
2. Select The Computer Or Video SourcePress the INPUT button on the remote control to select the desired
source. Or press the MENU button on the remote control and use
the Source Select to select your video source: Video, S-Video, RGB,
Y/Cr/Cb, RGB Digital (XT5100 only) or SDI.
3. Adjust The ImagePress the ADJUST PICTURE button or the ADJUST WHITE BAL
on the remote control or select the [Advanced Menu] → [Adjust
(Source)] to adjust the picture.
4. Turn Off The ProjectorFirst press the POWER OFF button on the remote control or the
projector cabinet. Allow the fan to cool the projector for three min-
utes. This will extend the life of the lamp. After the cooling fan stops
working, the POWER indicator will change to a steady orange glow
and the projector will be in the stand-by mode. Then turn off the
main power switch on the rear panel. The POWER indicator will go
out. If you desire to move the projector then unplug the power cable.
IMPORTANT:
•The projector will turn off and go into the standby mode after 1600
hours of service.
•The projector should be unplugged if it will not be used for an ex-
tended period.
•If you want to turn off the image briefly (five minutes or less), press
the MUTE PICTURE button instead of turning the projector off and
on.
•The projector will display a black, blue image or logo if no input signal
is present.
•Do not turn the projector off and then immediately back on. The Pro-
jector needs to cool down for three minutes before it is powered on
again.
CAUTION: Do not turn off the main power while the cooling fan is working.

YTR Adjustmen (not available for RGB)
Adjusts luminance transient time.
CTR Adjustment (not available for RGB)
Adjusts chroma transient time.
Option Adj
According to the signal, this function sets the detection position (i.e.,
clamp position) of the black level reproduction of the analog input
signal. Normally this is not used.
Auto ............. This is the normal setting.
Tri-Sync ....... This is set when projecting HDTV video.
Front Porch .. This is set when the picture quality does not improve even
though Auto or Tri-Sync has been set.
Adjust .......... This permits the video clamp position for each signal to be
set. Use Adjust when a clamp timing error occurs at the time
of special analog signal reception such as 1080P. Note that
Adjust is not valid for doubler signals such as NTSC and
PAL.
Sync Protection
When a VCR, DVD, or some other equipment that supports
Copyguard (a copy prevention system) is played back, the screen
may be displayed in a curved manner. Adjustments are made in
such circumstances. Use the SELECT 

 or  button to adjust the
Upper of Lower levels.
VD Delay
This feature is used to correct vertical jitter of non-standard inter-
laced signal. Select one of the three VD delay levels.

Switcher Gain
This feature adjusts the input level of the signal. This must be done
to each color:R, G, and B.
Volume
This feature adjusts the volume of the audio output. Adjust the sound
corresponding to the slot.
Ref Adj
Keystone
This feature corrects the keystone (trapezoidal) distortion to make the
top of the screen longer or shorter to be the same as the bottom.
Use the 

 or  buttons on the slide bar to correct the keystone (trap-
ezoidal) distortion.
Keystone distortion
Normal
NOTE:
1) With the projector aimed directly at the screen the maximum keystone angle
that can be corrected is +/- 15 degrees.
2) When Resolution is set to Native, this feature is not available, and the stored
settings and adjustments are invalid.
Depending on the type of graphics being used, the picture may get blurred or
keystone correction may not be possible when excessive keystone correction
is used.
The idea is, the closer you are to native resolution, the better image you will
see.
NOTE: The keystone feature is not available when the test pattern or the blueback is displayed.
Switcher (available only when used with ISS-6020)
The Lens Memory function stores the adjusted values when using shift,
focus* and zoom buttons on the projector cabinet or the remote control
for a specific signal.
Example of usage:
When a signal with 4:3 aspect ratio and a signal with 5:4 aspect ration
both need to be displayed on the 4:3 screen.
Normal Condition (for the above example)
Perform shift, focus* and zoom adjustments to the signal with 4:3 as-
pect ratio first since it is the native resolution of the projector. Both sig-
nals with 5:4 and 4:3 aspect ratio can be displayed, however the signal
with 5:4 aspect ratio will not fit properly on the screen.
To eliminate this size change, optimum values for shift, focus* and zoom
can be stored separately for the two signals. This can be done also for
two signals with the same aspect ratio. Memory (storage) of these val-
ues allows projected images to be optimum upon signal switching.
Follow the procedure below to accomplish this.
Lens Memory
1) Select Projector Options → Setup → Page 4 → Lens Memory and
insert a check mark in the Lens Memory check box.
2) Set the projector to no-signal condition or project a signal (in the above
example a signal with 4:3 aspect ratio) and adjust shift, focus* and zoom.
3) Select Adjust (Source) → Lens Memory → Reference/Custom and set
to Reference.
4) Press Store to store the lens values for this signal into memory.
5) Project a different signal (in the above example, a signal that is not 4:3
aspect ratio or a signal with 4:3 aspect ratio that you wish to adjust with
different values) and adjust shift, focus* and zoom.
6) Select Adjust (Source) → Lens Memory → Reference/Custom and set
to Custom
7) Press Store to store the lens values for this signal into memory.
The difference between Reference and Custom
Reference is a memory with adjustment values stored for either a no-
signal condition or a newly input signal. Usually a signal with 4:3 aspect
ratio would be used since it is the native resolution of the projector.
Reference is a one-time only memory location.
Custom is a memory for a signal that would need adjustment values
stored that would be different from the values stored in the Reference
memory. Custom can be stored for each individual input signal.
Note that when Reference is stored, all values will be overwritten since
they are not adjustments that change with each signal.
In the example above, signals with 4:3 aspect ratios are recommended
for Reference, but signals having other aspect ratios can also be used.
Another method to store is to press the INFO button while holding the
CTL button of the remote control.
Note that when using the remote control for storing, storage will be in
Reference when the Lens Memory setting of the menu is Refer-
ence, and storage will be in Custom when the setting is Custom.
Defaults such as newly input signals are Reference.

46 for more information.Lens Memory
