 8.1  SWITCH ON FROM STAND-BY
By remote control: press one of 1...9
By keyboard: press Arrow Up or Arrow Down.
Fig. 32
When switching on from stand-by, the projector will turn
on the lamp (flashing green LED); after a brief warm up
period the image will be displayed (green LED on).  The
input automatically selected will be the last one memorised
prior to switch off 
(Fig. 32).
  8.2 SWITCHING OFF AND RETURNING TO STAND-BY
By remote control: press 
By keyboard: press key 
When switching off, the projector goes in to stand-by (red
and green LED flashing) memorising the input selection
at the time of switch-off.
The fans will continue to work until the lamp has cooled
down. They will stop automatically after this period.
  8.3  FAILURE OF THE LAMP TO LIGHT
Switching on from stand-by. If the lamp fails to come on
(the projector will automatically make five attempts), an
error will be registered by a flashing red LED. This can be
reset by switching the power switch to position O.
9. DESCRIPTION OF CONNECTIONS
To obtain the best performance from your projector, we
recommend the use of good quality “video cables” to the
various signal sources (75 ohm Impedance).
Poor quality cables will cause inferior picture performance.
For optimum connectivity we recommend you follow these
simple steps:
- With exception of coaxial RCA/Phono type connectors,
always double-check that the plug is inserted the correct
way round to avoid damaging the plugs or the sockets
on the projector 
(Fig. 33).
75 
Fig. 33
-   Remove cables by the plug and do not pull on the
cable itself.
- Avoid tangled cables.
- Position the cables carefully to avoid a trip hazard -
especially in low light areas 
(Fig. 34).
Fig. 34
You may experience difficulties switching on
the projector shortly after turning off into stand-
by mode. This is not a fault. The lamp is still
too hot for the switch-on procedure to take
place.
Wait a few minutes before turning on again (position I),
this will allow the lamp to cool down to the correct tempe-
rature.
The life of the lamp is dependant on the number
of times the projector is switched ON and OFF.

10 INPUT SIGNALS
 10.1  COMPOSITE VIDEO INPUT
CVBS 
COMPOSITE VIDEO
Fig. 35
This input is suitable for a “Composite Video CVBS”. Via
a cable with an RCA/Phono connector 
(Fig. 35).
 10.2  S-VIDEO INPUT
S-VHS
S-VIDEO
Fig. 36
This input is suitable for equipment fitted with a S-Video output
to give improved picture performance (S-VIDEO / S-VHS)
Connection is made via a 4-pin mini-DIN  (
Fig. 36).
  10.3 VGA INPUT
Fig. 37
Personal Computers, Video Processors (scalers) and Vi-
deo Game consoles can be connected to the projector
via the HDB 15-Pin (VGA) terminal. Ensure the output ofequipment connected is RGB with one of the following
synchronisation options: separate H/V Sync, H+V Composite
Sync, (RGsB) composite sync on the green signal (
Fig. 37).
This input accepts a Horizontal Scan Frequency of
between 15-80 kHz and a Vertical frequency of between
40-100 Hz. Computer Resolutions of VGA, SVGA, XGA,
SXGA and UXGA can be displayed. The true native
resolution of the HT200 is SVGA (800 x 600) and the true
native resolution of the HT250 is XGA (1024 x 768).
10.4  RGB/YCRCB INPUT
RGSB - YS CR CBCOMPONENT 
VIDEO
Fig. 38
This input is suitable for a RGB video signal, or for a
Component Video (YCrCb) type, with composite
synchronisation on the green signal (RGsB) or on the
luminance (Y) signal (YsCrCb) through a cable with RCA/
Phono type connector 
(Fig. 38).
Only horizontal scanning frequencies of 15 kHz (standard
video resolution) or 32 kHz (high definition video, with pro-
gressive scanning) can be applied to this input.
  10.5 REMOTE INPUT INTERFACE CONNECTING CABLE
With a special cable (optional), it is possible to connect
the Remote Input Interface (optional) to the projector.
CAUTION: Connect/disconnect the special
Remote Input Interface cable only when the
projector is switched off and disconnected Upon switch on via the power switch, the projector
will automatically detect the Remote Input Interface,
identify which inputs are connected and these will
be added to the Input selection on the menu. If a single signal is applied to the projector and
that source was selected, the image coming
from that input will be projected.
If signals are applied to several inputs, you can
select the desired input by one of the following
methods:
- browsing the Source Selection menu, by re-
mote control or rear key pad
- pressing the remote controls digit key
corresponding to the desired input

never connect a computer to this socket. the
projector and the computer may be damaged
(Fig. 40).  10.7 RS232 INTERFACE CONNECTOR
RS 232
Fig. 42
It is possible to control the projector through a personal
computer. First, load the appropriate projector control
software onto your PC, then simply connect this input to
a cable from your PC’s RS232 serial port 
(Fig. 42).
The CD-ROM enclosed in the manual, provides all the
information needed to prepare the PC for RS232
connection, including the interface protocol and the
communication software.

  10.6 MOTORISED PROJECTION SCREEN OUTPUT
Fig. 41
The projector is equipped with two outputs (Voltage: 12
Vdc) for motorised projection screen and screen masking
systems. These 12V outputs should be connected to the
appropriate screen interface provided by the screen
manufacturer 
(Fig. 41).
The +12V output is activated when the projector is
switched on (green LED on) and is de-activated when the
projector is in stand-by mode (red LED on).
The output 
 is active when one of the following modes,
from the Image Aspect Ratio Selection Menu, is
selected: Normal, Letterbox and Zoom.
The output is inactive when the Anamorphic mode is
selected on the same Image Aspect Ratio Selection
Menu.
This output allows reduction in the area of a 16:9 screen,
into a 4:3 format, by activating a screen masking system
(refer to screen manufacturer for further information).

Change the batteries in the remote control if experiencing
difficulty in sending commands to the projector.
If the remote control is not to be used for a long period of
time remove the batteries. Replace all batteries at the
same time; do not replace one new battery with a used
battery. If the batteries have leaked, carefully wipe the
case clean and replace with new batteries.
The remote control sends commands to the projector via
infrared signals.
It is possible to control the projector by pointing the remote
control at the screen; the sensor at the front of the projector will
pick up the reflected infrared commands. 
(Fig. 44).
Fig. 44
Avoid placing obstructions between the remote control
and the infrared sensor at the front of the projector; this
will impair the remote control performance.

13.3.2  KEYSTONE
  If the projector is at an angle in relation to the screen,
keystone distortion will occur. Use the keystone
adjustment to restore the projected image to the correct

degrees.  If the projector is level then use the lens shift feature
to correctly position the image on screen 
(Fig. 47).
Fig. 47
To obtain maximum quality of the projected image, we
recommend the installation of the projector on a level
platform parallel and central to the screen. In the event
that the picture is not correctly positioned use the lens
shift feature.
Should it not be possible to centralize the image by
adjusting the lens height, tilt the projector, but this will
create keystone error (please refer to 13.3.2).
