•PROTECTION AGAINST FIRE
1) This unit has been made to work only with the Lamp: MSD 250/2 (PHILIPS).
!ABSOLUTELY NEVER USE OTHER KIND OF LAMPS.
2) Keep a minimum distance of 0,3 mt. from walls or any inflammable surface.
3) Keep a minimum distance of 1 mt. from lighted objects.
4) Replace the fuses with others of the same kind and value (MAIN FUE 5x20 250V 5A; ELEC FUSE 5x20 250V 2A).
5) Do not install the projector close to heat sources. Do not lay the connection cables on the projector when it is hot.
•PROTECTION AGAINST ELECTRIC SHOCKS
1) This projector must be earthed.
2) Class I equipment. The protection conductor must be part of the power supply cable.
3) For the connection to the main power supply proceed as in fig. 2, page 6.
4) Disconnect the power supply before the Lamp replacement or before opening the unit.
5) Do not install the projector outdoors, exposed to rain or moisture.
•PROTECTION AGAINST MECHANICAL HAZARDS
1) When installing the projector use a safety chain.
2) To avoid explosion risks, open the projector only after 5 minutes after the lamp is off.
3) The temperature of the projector can reach 85°C. Wait for almost 5 minutes before operating on it.
4) Replace the Lamp if it is damaged or deformed by the heat.
•PROTECTION AGAINST UV RADIATIONS HAZARDS
1) Do not start on the projector without the protecting screen or if the lenses and the ultra-violet filters are
damaged.
2) The protecting screens, the lenses and the ultra-violet filters must be replaced if visibly damaged and if their
efficiency has been reduced, for example by slits or deep cuts.
3) Do not directly look at the Lamp when it is on.
•WARNINGS
1) Do not dismantle and modify the unit.
2) To avoid any inflammable liquids, water or metal objects entering the unit.

BEFORE USING THE PROJECTOR
!Carefully read the precautions on page 3 before installing the projector.
In particular read the following points:
1) Disconnect the power supply before replacing the lamp or doing any maintenance job.
2) Do not open the projector if are not passed at least 5 minutes after it went off.
3) Always wear protective gloves and goggles to replace the lamp or to work inside the projector.
4) The protecting screens, the lenses and the ultra-violet filters must be replaced if visibly damaged.
Slits or deep cuts remarkably reduce their efficiency.
5) To avoid any bad performance of the projector or that the lamp breakage could damage its optic,
replace the lamp as soon as it reaches its average life time (2000 hrs).
6) Periodically clean the in/out air grates.
7) In case the projector must be held on a structure (truss), make sure that it is well and safely fixed,
even using a safety chain from the projector to the structure.
8) Do not install the projector outdoors, directly exposed to rain and moisture.
9) Before connecting the projector to the main power supply, make sure that the working voltage and
frequency correspond to the values indicated on the label (fig. 2/a).
The MH-250 is supplied to work at a working voltage of 230V 50Hz (60Hz on request); 1,8A.
For being supplied with a voltage of 100-120V it is absolutely necessary an auto-transformer with
the following characteristics:
• Output voltage 230V.
• Output current 4A.
10) The connection of the projector to the mains is described in fig. 2:
10 a) Do not install the projector close to heat sources. Do not lay the connection cables on the
projector when it is hot.
10 b) The unit must be placed where it could be easily aerated. To avoid obstructing the in/out air
gratings.
10 c) The projector must be distanced almost 0,3 mt. from walls or any inflammable surface
and almost 1mt. from lighted objects.
11) Temperature on the unit’s external surface:
• after 5 minutes Tc = 65°C.
• when the thermic balance has been reached Tc = 85°C.
The unit must be connected to the earth. The inobservance of these
instructions automatically makes the guarantee expiring.

DMX LINE TERMINAL
Do not connect or wrongly connect the DMX line terminal is probably the most common cause of a defective
functioning of a DMX line.
The DMX line terminal is a resistance placed between the two data pin 2 and 3 at the end of the line.
The terminal resistance should ideally have the same value of the impedance of the DMX connecting cable.
On the MH-250 is inserted a resistance value of 100 Ohm that can be started by a switch placed on the base rear panel
(fig. A).
!It is suggested for all DMX systems to use a DMX line terminal (DMX line terminator ON, fig. A) only on the
last connected unit.
!Usually the DMX connection is insulated from the unit mass. In some cases (very rarely) it is suggested to act
in a different way. On the base rear panel there is a switch that connect electronical the two masses (DMX Gnd).
Use this switch (DMX Gnd ON, fig. A) only if the DMX line functioning is not stable although connection and
termination are correct.

DMX SIGNAL CONNECTION
The DMX signal connection to the MH-250 must be done through the input signal connectors XLR 5 pins, placed
on the rear panel of the projector (fig. 5).
The nomenclature of the pins of the DMX input connectors is listed in the table reported in fig. 5/a.
To avoid any problem in the transmission of the signal it is recommended to use a cable for very fast data transmissions.
A normal audio cable is suitable only for lines long not more than 100mt.
The best performances and the maximum stability are obtained using a shielded microphonic cable which section
must be of at least 2x0,25mm, or, a data transmission cable.
In case of lines long more than 150/200mt. it is recommended to use a DMX Repeater Amplifier.
On the MH-250 control panel (fig. 6) besides the display there are some led and buttons which allow the projector
correct configuration.
LED
• Led “DMX” flashing: the DMX input signal is On;
off: the DMX input signal is Off..
• Led “LAMP OFF” flashing: the control board lamp is Off;
off: the lamp is On.
BUTTONS
There are four buttons which allow the complete programming and management of the projector:
• MENU allows the selection of the
programming options;
• DOWN allows to run the selected options
back;
• UP allows to run the selected options
forward;
• ENTER confirms the options selected.
DISPLAY
It shows the different configuration menu and the options selected.
