the vertical bands (see illustration).TUNE
· Adjust the tuning up/down keys to stabilize the
image. Preferably all the “sideways swimming” lines

800x600, select SCALE.  This will scale the source
resolution to fit the LCD screen resolution by
adjusting the number of vertical and horizontal pixel
lines at intervals throughout the image.

							USER GUIDELCD PROJECTOR22 7 USING THE LCD PROJECTOR
The LCD projector has a set of features and functions with which you
need to be familiar with in order to operate the unit efficiently and to
allow you to make a smooth, problem-free presentation.
7.1 INFRARED REMOTE CONTROL
The infrared remote control is the main user interface with the projector.
The remote control is used to set the LCD projector correctly so that the
best viewing conditions are achieved, and also to control your
presentation.  The functions performed by the keys on the remote control
are described below.LEFT DRAG

							USER GUIDELCD PROJECTOR26 7.2 TOP PANEL KEYBOARD
The settings most likely to be adjusted during the set-up process are also
accessible via a secondary keyboard panel on the top of the LCD
projector, known as the Top Panel Keyboard. The Power ON/OFF
Indicator is also located on this panel.  The panel layout is shown below.
The buttons function exactly as the corresponding remote control keys,
with the exception of TUNE which uses a single button to adjust settings
in a wrap-around scale.LCD PROJECTORRESET

							USER GUIDELCD PROJECTOR27 8 SPECIAL FEATURES OF YOUR LCD
PROJECTOR
8.1 INTELLIGENT COOLING 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.
8.2 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 function table in section
Using the LCD Projector.
8.3 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 PROJECTOR28 8.4 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.8.5 POWER SAVE FEATURE
If ON/OFF is pressed on the remote control, the screen goes blank, and
after five minutes if there is no futher action the LCD projector lamp will
also switch off.  Full power on is returned by pressing ON/OFF again on
the remote control. 
						

							USER GUIDELCD PROJECTOR29 9 TROUBLE-SHOOTING
This is a checklist to help you pinpoint any problem that may arise.
Check the symptoms carefully if you experience any problem.  The cure
may be at your fingertips!Always check that the OSD appears when the OSD key on
the remote control is pressed.  This indicates that the LCD
projector is receiving signals from the remote control.SYMPTOMSOLUTIONLCD projector
