• PRISM SELECTION (16 channel operation) - channel 15
From 0% to 49.7% the prism rotates
through 540° (1 1/2 turns).
From 50% to 75% the prism turns
more quickly at first, then slows down
to a complete stop.
From 75.5% to 100% the prism begins
turning in the opposite direction, slow-
ly at first and then more quickly.

IMPORTANT: for uniform distribution of the light
beam, the lamp must be positioned so that the
glass pip (37) on the bulb does not coincide with
the optical axis of the projector. With this in
mind, locate the pip as high up as possible.
• Opening the projector
Free the access cover (12) by loosening the knob (15), and remove from the projec-
tor. Once the necessary work has been completed, refit the cover (12) and retighten
the knob (15).
• Changing the lamp
Open the projector, loosen the two side nuts (35)
of the lamp to be changed and remove it from the
supports (36).
Remove the new lamp from its packaging, loosen
the two side nuts (35) and locate the lamp in the
supports (36). Finally, retighten the nuts.

IMPORTANT: isolate the projector from the electrical power supply before com-
mencing maintenance work of any description.
The maximum temperature on the outer surface of the projector under normal
operating conditions is 90 °C (194° F).
After switching off, do not remove any part of the projector for at least 10 minutes,
as indicated on the lamp change label (1).
Once this time has elapsed, the risk of a lamp exploding is practically zero. If the
lamp needs changing, wait a further 20 minutes to avoid the risk of burns.
In the event of a lamp exploding, the appliance is designed to prevent fragments of glass
from being scattered. Lenses and clear filters supplied with the appliance must be fitted
at all times, and if visibly damaged must be replaced promptly with genuine spares.
CAUTION: The projector uses a high pressure discharge lamp with
external starter.
- When fitting a new lamp, read the manufacturer’s instructions carefully.
- The lamp must always be changed without delay if damaged or deformed by heat.

• Zero setting the working hours and number of times the lamp is switched on
To zero the hours of the lamp’s life (“Bulb hours”) and the number of times it is
switched on (“Bulb strikes”) which are stored in the DMX Receiver microprocessor,
proceed as follows:
1. Set the TEST microswitch (38) to the ON position.
2. Shift the option 1 microswitch (39) from ON to OFF (or from OFF to ON) and vice
versa 3 times within a time of 6 seconds. If the procedure has been carried out
correctly, the three signal control LEDs (40) will light up simultaneously, while the
display (41) will go completely blank. This situation lasts for approximately
5 seconds.
3. Return the TEST microswitch (38) to the OFF position.

• Changing the colour filters
Having opened the projector, identify the filter
to be changed, grip firmly between thumb and
forefinger and push against the spring clip
(42) until free of the fixed clips (43).
Bend the filter outwards and remove.
Offer the new filter to the spring clip (42) and
anchor behind the two fixed clips (43).
• Changing metal gobos
Having opened the projector, identify the gobo
to be replaced and push gently toward the
clips (44) until free. Take the selected replace-
ment from the holder (45) on the gobos/iris
plate. Offer the new gobo to the two clips,
push gently and locate behind the third,
checking for flatness.
