3 INTRODUCTION
Congratulations, thank you for choosing the  HT 200/250,
a 
 Multimedia SpA product (Fig. 1).
Fig. 1
Using the very latest in  technology (TI copyright),
this projector has been designed specifically for high quality
“Home Cinema” applications. The HT 200/250’s portability and
versatility also means it can be used to display images from
PCs for presentations, computer games and Internet.
Sophisticated digital processing and a wide choice of
inputs enable the connection of a variety of sources such
as DVD players, analogue and digital VCRs, analogue
and digital satellite receivers and personal computers etc.
The long throw projection lens has been designed to allow
the position of the projector to be located behind the
viewer, similar to that of a real cinema 
(Fig. 2).

The carton should contain the following:
projector remote control, four 1.5V, AAA batteries (for re-
mote control), three power cables (EU, UK, USA) and
users manual and CD-ROM.
To unpack the projector safely and easily please follow
steps 1 to 6, as per drawing 
(Fig. A).
It is recommended that the carton and packaging is
retained for future use and in the unlikely event that your
projector needs to be returned for repair 
(Fig. B).

Only replace the safety fuse (on the power socket at the
rear of projector) with a fuse identical in type and
characteristics (T 3.15A H) 
(Fig. 8).

CAUTION: A special EVC socket on the
projector’s rear panel will allow connection to
the optional Remote Input Interface (a special
cable is required).
This is not to be confused with a VESA “Plug
& Display”
Never connect a computer to this socket, as
the projector and the computer may be
damaged (Fig.4).
Connect the projector to a power supply with a nominal
voltage within the following values: 100-240 Vac, 50/60 Hz,
earthed 
(Fig. 5).
100-240 Vac50/60 Hz
Fig. 5
The mains plug is the disconnect device. Take care when
installing, that the mains plug and socket outlet are easily
accessible. Never pull on the cable to take it out of the socket.
If the system is unlikely to be used for a number of days,
disconnect the power cable and other apparatus connected to
it; also disconnect the aerial cable (where applicable).
Fig. 6
To save energy, switch off the projector by using the power
switch at the rear; in stand-by (red light on) the projector
continues to draw a minimal amount of power 
(Fig. 7).

ENGLISH
Do not obstruct the cooling air inlets on the top cover, or
the air outlets underneath the projector 
(Fig 11).


CAUTION: Do not switch on the projector if it
is standing on soft surfaces such as cushions,
pillows, blankets, mattresses and carpets: the
air cooling outlets underneath, could become
obstructed
.
Fig. 12
Take care not to shake the projector whilst carrying it by
the handle 
(Fig 15).
Fig. 15
Always position the projector on a stable, suitable surface,
away from direct heat sources.
Do not touch the surface of the projection lens.
Do not rest the projector on the side panels or on the rear
panel when in operation 
(Fig. 16).
OK! OK!
Fig. 16
Take care to position cables safely, especially in dark
places, in order to avoid a trip hazard  
(Fig. 17).
Fig. 17
CAUTION: Intense Light Source!  Do not stare
directly into the projection lens as possible eye
damage could result.  Be especially careful that
children do not stare directly into the beam (Fig. 13).
Do not open the projector’s cover; no user serviceable parts
are inside. Refer servicing to qualified service personnel.
Opening the projector’s cover will invalidate warranty 
(Fig .14).
Fig. 14


Do not switch-on the projector if it is standing
on surfaces sensitive to heat, as this may result
in damage caused by the hot air outlets
underneath. Should this be unavoidable take
extra precaution of protecting the surfaces with
a layer of heat resistant material (Fig. 12).
Fig. 11
Fig. 13


CAUTION: For installations using a ceiling or
wall-mounted bracket, carefully follow the
installation and safety instructions provided
with the bracket’s literature.
Please remove batteries from the remote control if not in
use for a long period of time.

6 INSTALLATION
LOCATION OF PROJECTOR AND SCREEN
The long throw projection lens has been designed to allow
the position of the projector to be located behind the
viewer, similar to that of a real cinema 
(Fig. 2).
Position the projector on a stable, suitable platform or
utilise the optional bracket for a fixed ceiling or wall
installation.Should the projected image appear not to be level, adjust
the feet underneath to obtain a level position, lining up
the base of the projected image to the base of the
projection screen 
(Fig. 21).


CAUTION: In the case of ceiling or wall mounting
using a suspension bracket, follow the instructions
carefully and comply with the safety standards you
will find in the box together with the bracket. If you
use a bracket different to the one supplied by 
Multimedia, you must make sure that the projector
is at least 6.5 cm (2.6”) from the ceiling and that the
bracket is not obstructing the air vents on the lid
and on the bottom of the projector.

The Orientation adjustment in the Set up menu will allow
the projector to be used for desktop front, ceiling front,
desktop rear and ceiling rear installations 
(Fig. 26).
Fig. 26
To activate an electric motorised screen a 12 Volt output
is provided at the rear of the projector or with the optional
Remote Input Interface.  This can be connected to a screen
interface unit, which can be supplied by screen
manufacturers 
(Fig. 27).
Fig. 27
The output is activated (Voltage: 12 Vdc) when the
projector is switched on (green LED on) and is de-activated
(no Voltage output) when the projector is in stand-by mode
(red LED on). Adjust the motorised zoom lens to enlarge or reduce the
projected image.
Adjust the motorised focus of the lens to achieve maximum
clarity.
With optimum focus you should be able to clearly see
each single pixel of the DLP when within close proximity
to the screen 
(Fig. 23).

Enter the Set up menu, by remote control or keyboard, to
adjust the motorised Zoom and Focus; alternatively
directly press the Focus or Zoom 
 button on the remo-
te control or 
-Focus-Esc on the keyboard pad. V+ and
V- should be used for adjustment.
The manual lens shift adjustment allows the projected
image to be moved vertically, up or down, in relation to
the centre of the screen; the maximum adjustment being
equal to half the height of the image in either direction
(Fig. 24).
Fig. 24
In the event you are unable to centre the image within the
screen area, tilt the projector until the image is correctly
positioned. Any Keystone error can be removed by the
keystone adjustment in the Set up menu 
(Fig. 25).

Fig. 28
Some manufacturers offer screen-masking systems to
help frame the projected image and improve picture
contrast.  This can be controlled by the second 12V output
on the projector 
(Fig. 28).
The screen-masking interface can be connected to output
,  at the rear of the projector, or on the optional Remo-
te Input Interface.
- Rear projection: the screen must be translucent.
- Front projection: preferably, use a screen with black,
non-reflecting borders, which will perfectly frame the
projected image.
Avoid light shining directly on the screen during projection
as this will reduce contrast and black level detail on the
projected image.  For the true cinema experience best
results are achieved with little or no ambient light.
Furniture and other objects with reflecting surfaces, as
well as light coloured walls should be avoided, as they
are likely to interfere with the screen’s characteristics.
We recommend the use of screens with low gain
specifications (i.e. 1.3 to 2).  The use of high gain screens
should be avoided due to their limited viewing angle, which
is undesirable for a large audience.

CAUTION: Connect the projector to a power
supply with a nominal voltage within the
following values:  100-240 Vac, 50/60 Hz. It
must be earthed (Fig. 30).
Do not install - or operate - the projector on its
side: this position will dramatically shortens
the life of the lamp (Fig. 29).
