							USER GUIDELCD PROJECTOR22 9 FEATURES
The LCD projector has a variety of different features implemented. This
chapter explains each feature in detail.
9.1.1 INTELLIGENT SAFECOOL SYSTEM
The fan operates as long as the LCD projector is switched on. Provided
that the power cord is connected, the fan continues to run for 2 minutes
even after the unit has been switched off. This ensures a continuous
protection against high temperature inside the projector. The cooling
system is designed to minimize stray light and noise. If the air flow is
blocked, a temperature safety fuse will automatically shut off the projector
to protect it from overheating.
9.1.2 SET-UP MEMORY
The user controlled set-up, that usually is done when the projector is
connected to a new computer, is automatically memorized for future use.
The set-up information is stored in a non-volatile memory approximately 5
seconds after the last key is pressed.
The memory can store 40 different sources/modes. Some sources are
predefined, while the remaining are available for customer set-up. See the
Technical Data section for compatibility.
Custom sources are added to the memory only if their sync pattern differs
from any of the previous selections. The projector automatically selects a
new memory location.
Most settings are stored individually for each mode, including contrast,
brightness, tune etc. See the remote control table in the Remote Control
section.
OSD SYSTEM
The OSD (On Screen Display) system echoes on screen your keypad or
remote control actions. The OSD may be switched off and on by pressing
the OSD key on the remote control. 
						

							USER GUIDELCD PROJECTOR23 9.1.3 CONTRAST
The contrast of an image is defined as the relation between dark and light
colors. An image of high contrast is often regarded as ‘hard’, as compared
to the ‘soft’ feeling of a low contrast image. Low contrast is recommended
for long term viewing, while high contrast is used to enhance details. Use
the CONTR keys on the remote control (RC) to adjust the contrast. Also
see Brightness. The contrast setting is stored individually for each mode.
9.1.4 BRIGHTNESS
The brightness is the amount of white in an image. The brightness is
adjusted to the ambient lighting conditions. Usually, a bright, low contrast
image is preferred. Use the BRIGHT keys to adjust brightness. See also
Contrast. The brightness setting is stored individually for each source.
9.1.5 TUNE
This feature enables a stable image. An unstable image can be seen as
sideways instability or “swimming”. Press TUNE until a stable image is
achieved. The setting is stored individually for each source. Observe that
TUNE only works provided the FREQUENCY setting is correct.
9.1.6 ON/OFF
This switch controls the operation of the projector. When switched on, all
functions are active. When switched off, the fan is still operating, but the
image is turned off. If the unit is left off for more than 5 minutes, the lamp
is also turned off and after another 2 minutes the fan terminates. The
ON/OFF switch is a toggle key.After the lamp is turned off, the unit can only be turned on
again after a safety delay of 60 seconds. If the projector is
turned on during the safety delay period, the On/Off indicator
will blink slowly until the 60 seconds have passed and the lamp
is turned on.9.1.7 RESET
This feature enables standard settings of most controls. RESET will only
reset the active mode.A fundamental master reset may be performed by pressing all
four top panel keys simultaneously. All settings will return to
factory defaults, so do not perform a master reset unless it is
really required. This operation will also erase all custom
sources and modes that have been memorized. 
						

							USER GUIDELCD PROJECTOR24 9.1.8 SOURCE 1/2/3
These keys select between the 3 analog RGB inputs. Only one input can
be active at a time. All three inputs have the same properties and can be
used for either computer/workstation or RGB video sources.
The Projector defaults to input source 1 at power on. If no signal is
connected, the message NO SOURCE appears on the screen.
9.1.9 FREEZE
Press the FREEZE button on the RC to lock the image displayed. This
feature is useful if you want to make changes locally on your computer that
should not be presented to the audience. Press FREEZE once more to
resume on-line operation. Any other key pressed will also release
FREEZE.
9.1.10 BLANK
Use the BLANK key on the RC, if you temporarily want to suspend the
display of images. The BLANK key is a toggle function, and the screen
goes blank when activated. Any key pressed will release BLANK.
9.1.11 REAR
The projector can be set to project a mirrored image for rear projection.
Rear projection is used when only the actual image is displayed, without
showing the projection equipment. A special transmissive screen is
needed. A typical application is in exhibitions. REAR is a toggle function on
the RC.
9.1.12 FREQUENCY
This setting is provided for adaptation to Workstations and special
graphics adapters that are not recognized automatically by the projector.
An incorrect frequency setting can be seen as an image to wide or too
narrow, combined with vertical, unstable bands. To better see this effect,
fill a large portion of your screen with a 50% grey pattern (alternating black
and white pixels). Make sure that Expansion/Compression is deactivated
i.e. your image is viewed in default 1:1 mode. This is done by pressing the
SCALE key on the remote control. Press the FREQUENCY keys left or
right to adjust the setting until all vertical banding disappears. The final
setting is stored individually for each source.
9.1.13 POSITION
Due to minor variations in graphics adapters, the horizontal and vertical
position may need adjustment. Press POSITION, then use the cursor keys
to position the image. The position is stored individually for each mode. 
						

							USER GUIDELCD PROJECTOR25 9.1.14 SCALE
Scaling is applicable to images that have a lower or higher resolution than
the 1024x768 active LCD area. Pressing SCALE toggles between direct
mapping (1:1) and compression of oversized images (1280x1024 or
1152x900), or expansion of undersized images (640x480 or 800x600).
Default power on setting for oversized images is to view the image in 1:1,
undersized images are expanded.
9.1.15 PAN
Panning is only applicable with oversized images (1280x1024 and
1152x900) when displayed in 1:1 (not compressed, see SCALE). Press
PAN , then use the cursor keys on the remote control to perform the actual
panning.Observe that the mouse cannot be controlled from the remote
while PAN is activated.The PAN function is automatically deselected after 5 seconds of no key
activity.
OSD
The OSD (On Screen Display) is switched on or off with this toggle key.
9.1.16 MOUSE
The BatMouse remote control (RC) employs a unique mouse functionality
that enables full mouse control of your PC, PS/2 or Macintosh computer.
By default, the cursor keys of the remote control emulate the mouse
movement.
The LEFT and RIGHT keys emulate the left and right keys on a standard
two-key mouse (for Macintosh, only the DRAG key is used).
The DRAG key is used to emulate the click-and-hold action. To move an
object, position the mouse cursor, press DRAG to tag the object, position
the object as desired using the cursor keys, then press DRAG again to
release the object. DRAG is automatically released after 5 seconds of no
key activity.The mouse control can only be used with computers that fully
support PC, PS/2 or MAC ADB mouse - electrically and
functionally.
