Unpacking Instructions
Immediately upon receiving a fixture, carefully unpack the carton, check the contents to ensure that
all parts are present, and have been received in good condition. Notify the shipper immediately and
retain packing material for inspection if any parts appear damaged from shipping or the carton itself
shows signs of mishandling. Save the carton and all packing materials. In the event that a fixture
must be returned to the factory, it is important that the fixture be returned in the original factory box
and packing.
AC Power
To determine the power requirements for a particular fixture, see the label affixed to the back plate of
the fixture or refer to the fixture’s specifications chart. A fixture’s listed current rating is its average
current draw under normal conditions. All fixtures must be powered directly off a switched circuit and
cannot be run off a rheostat (variable resistor) or dimmer circuit, even if the rheostat or dimmer
channel is used solely for a 0% to 100% switch. Before applying power to a
fixture, check that the source voltage matches the fixture’s requirement.
Check the fixture or device carefully to make sure that if a voltage selection
switch exists that it is set to the correct line voltage you will use.
Warning! Verify that the power select switch on your unit matches the
line voltage applied. All fixtures must be connected to circuits
with a suitable Earth Ground.

SETUP
Lamp
You will need to install a lamp prior to the initial operation of the fixture. An MSD250 high intensity
discharge lamp is included.
Warning! When replacing the lamp, please wait 15 minutes after powering down to allow the
unit to cool down! Always disconnect from main power prior to lamp replacement.
Do not touch the envelope (glass area) of the bulb with bare hands. If this happens, clean the lamp
with alcohol and wipe it with a lint free cloth before installation.
Lamp Installation
1. Remove screws labeled (S1) and pull out lamp socket plate.
2. If replacing the lamp, remove old lamp first.
3. Holding the new lamp by its base, align the pins on the lamp
with the small hole in the socket and insert the lamp squarely
until the retaining clips on the lamp socket secure the lamp
tightly.
4. Clean the glass/envelope of the bulb with an alcohol wipe or
equivalent.
5. Holding the lamp socket plate, insert the tip of the lamp into the
fixture with extreme care. Navigate the lamp all the way until it
reaches the reflector and the lamp base plate touches the
bottom plate of the fixture.
6. Align the screw holes and fasten the screws back onto the
lamp socket plate.
7. If you are replacing the lamp, you may want to log the fixture
hours in order to track the lamps use. Navigate to the H000 on
the menu display to obtain this information. Please note that it
is normal for the fixture to have logged a few hours of testing
prior to your use.
8. Turn the fixture on and adjust the lamp alignment screws (S2)
until the brightest most even area of the beam is in the center of your spot. It may be necessary
for you to use a controller in order to command the fixture to display a white beam on a flat surface
with no colors.
Maximizing the life of your lamp
To ensure the longest and most efficient use of the lamp always wait
between 10 and 15 minutes before re-applying power after a shutdown.
Failure to do so could result in premature aging of the lamp and failure to
the electronics that drive it.

Lamp Alignment How-To
Often, after a new installation of a lamp, you will find that there
is an uneven field of light or what is referred to as a hot spot.
This is due to the most intense point of the lamp source not
being positioned optimally within the reflector.
There are three lamp alignment screws provided at the base of
the projector head. Turning these screws allow you to optimize
the projection quality of the spot as well as the overall intensity
of the beam.
1. Project a white spot against any flat surface. Preferably the
surface should be white or pastel in color.
2. Turning the lamp alignment screws, try to position the hot spot in the
center of the beam as best as possible. This could require many
attempts on your part.
3. Once the hot spot is in the center of the spot, do your best to turn all
screws equally as to affect movement up or down within the reflector.
4. As you move in and out of optimum lamp focus, you will see the hot spot either gets wider or
narrower. The goal is to either totally diminish the hot spot by having it widen and spread across
the entire spot or moving the hot spot so that it covers as much of the beam spot area as possible.
Power Your product is equipped with switch-selectable AC power setting.
Warning! Verify that the power select switch on your unit
matches the line voltage applied. All fixtures must
be connected to circuits with a suitable Earth
Ground.
To determine the power requirements for a particular fixture,
see the label affixed to the back plate of the fixture or refer to the fixture’s specifications chart.
A fixture’s listed current rating is its average current draw under normal conditions.
All fixtures must be powered directly off a switched circuit and cannot be run off a rheostat
(variable resistor) or dimmer circuit, even if the rheostat or dimmer channel is used solely for a 0%
to 100% switch.
Before applying power to a fixture, check that the source voltage matches the fixture’s
requirement.
All fixtures must be connected to circuits with a suitable Earth Ground.

DMX Mode
Operating in a DMX Control mode environment gives the user the greatest flexibility when it comes to
customizing or creating a show. You can tailor your programming to suit a specific event. Whether it
is a wedding where a spot light may be required or a lead singer requiring a color solo, the
opportunities are endless. In this mode you will be able to control each individual trait of the fixture
independently.
Daisy Chain Connection
1. Connect the (male) 3 pin connector side of the DMX cable to the output (female) 3 pin connector
of the first fixture.
2. Connect the end of the cable coming from the first fixture which will have a (female) 3 pin
connector to the input connector of the next fixture consisting of a (male) 3 pin connector. Then,
proceed to connect from the output as stated above to the input of the following fixture and so on.
Menu Functions
DMX-512 addressing
This mode enables the use of a universal DMX controller device. Each fixture requires a "start
address" from 1 to 511. A fixture requiring one or more channels for control begins to read the data
on the channel indicated by the start address. For example, a fixture that occupies or uses 6 channels
of DMX and was addressed to start on DMX channel 100, would read data from channels: 100, 101,
102, 103, 104, and 105. Choose start addresses so that the channels used do not overlap and notate
the start address selected for future reference.
If this is your first time addressing a fixture using the DMX-512 control protocol than I suggest jumping
to the Appendix Section and read the heading “DMX Primer”. It contains very useful information that
will help you understand its use.
Setting the starting address
1. Press the [Choose] button until the display reads “ANNN”where N represents a number from 0 to
9.
2. Press the [Up] and [Down] buttons to increase or decrease values until the desired value is
achieved.
3. Press the [Enter] button to activate selection.

P1 - Pan Invert / P2- Tilt Invert
It is possible to invert the pan and tilt mirror movement from within the fixture itself. This could be
helpful in situations where the positioning or rigging of a fixture led to a reverse orientation of the
fixture in relation to all or most other fixtures installed. When choosing to command the pan or tilt of
all fixtures at the same time you will notice that the fixtures whose orientation is different from the
others will most likely move opposite of the rest. You can apply a pan and tilt Invert by following the

APPENDIX
DMX Primer
There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A
fixture capable of receiving DMX-512 will require one or a number of sequential channels. The user
must assign a starting address on the fixture that indicates the first channel reserved in the controller.
There are many different types of DMX controllable fixtures and they all may vary in the total number
of channels required. Choosing a start address should be planned in advance. Channels should
never overlap. If they do, this will result in erratic operation of the fixtures whose starting address is
set incorrectly. You can however, control multiple fixtures of the same type using the same starting
address as long as the intended result is that of unison movement or operation. In other words, the
fixtures will be slaved together and all respond exactly the same.
DMX fixtures are designed to receive data through a serial Daisy Chain. A Daisy Chain connection is
where the DATA OUT of one fixture connects to the DATA IN of the next fixture. The order in which
the fixtures are connected is not important and has no effect on how a controller communicates to
each fixture. Use an order that provides for the easiest and most direct cabling. Connect fixtures
using shielded two conductor twisted pair cable with three pin XLR male to female connectors. The
shield connection is pin 1, while pin 2 is Data Negative (S-) and pin 3 is Data positive (S+). CHAUVET
carries 3-pin XLR DMX compliant cables, DMX-10 (33’), DMX-4.5 (15’) and DMX-1.5 (5’)
Fixture Linking
Note! If you use a controller with a 5 pin DMX output connector, you will need to use a 5
pin to 3 pin adapter. CHAUVET Model No: DMX5M.

Maintenance
To maintain optimum performance and minimize wear fixtures should be cleaned frequently. Usage
and environment are contributing factors in determining frequency. As a general rule, fixtures should
be cleaned at least twice a month. Dust build up reduces light output performance and can cause
overheating. This can lead to reduced lamp life and increased mechanical wear. Be sure to power off
fixture before conducting maintenance.
Unplug fixture from power. Use a vacuum or air compressor and a soft brush to remove dust
collected on external vents and internal components. Clean all glass when the fixture is cold with a
mild solution of glass cleaner or Isopropyl Alcohol and a soft lint free cotton cloth or lens tissue. Apply
solution to the cloth or tissue and drag dirt and grime to the outside of the lens. Gently polish optical
surfaces until they are free of haze and lint. Do not to touch the lamp glass when cleaning fixture. Oil
and dirt can cause damage and premature aging of the lamp. In the event that the lamp is touched or
becomes dirty, clean the lamps with an alcohol wipe.
The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically to
optimize light output. Cleaning frequency depends on the environment in which the fixture operates:
damp, smoky or particularly dirty surrounding can cause greater accumulation of dirt on the unit’s
optics. Clean with soft cloth using normal glass cleaning fluid. - Always dry the parts carefully. - Clean
the external optics at least every 20 days. Clean the internal optics at least every 30/60 days.
Returns Procedure
Returned merchandise must be sent prepaid and in the original packing, call tags will not be issued.
Package must be clearly labeled with a Return Merchandise Authorization Number (RA #). Products
returned without an RA # will be refused. Call CHAUVET and request RA # prior to shipping the
fixture. Be prepared to provide the model number, serial number and a brief description of the cause
for the return. Be sure to properly pack fixture, any shipping damage resulting from inadequate
packaging is the customer’s responsibility. CHAUVET reserves the right to use its own discretion to
repair or replace product(s). As a suggestion, proper UPS packing or double-boxing is always a safe
method to use.
Claims Damage incurred in shipping is the responsibility of the shipper; therefore the damage must be
reported to the carrier upon receipt of merchandise. It is the customer's responsibility to notify and
submit claims with the shipper in the event that a fixture is damaged due to shipping. Any other claim
for items such as missing component/part, damage not related to shipping, and concealed damage,
must be made within seven (7) days of receiving merchandise.
