2. INSTRUCTIONS
●CLEANINGANDMAINTENANCE
The accumulation of oil, smoke and dust on the lens will compromise the light output. Cleaning a projector is very necessary to
ensure a reliable use of it. Without the permissionbya qualified person for internal part replacement, it is forbidden to dismantle a
unit.
Cleaning frequency is to be decided byoperations and itsenvironment. Use soft cloth and normal detergent for glass for cleaning
work. It’s advised external optical system be cleaned every 20days. Keep lens clean and do not touch optical parts with bare
hands.
Special note:
For any waterproof projector, it's normal if there is some mild mist on the lens while in use.
●Beforeany maintenanceandcleaning,pleaseensuretheprojectisoffthepower

●RIGGING
Beforemovingtheunit,lock theadjustingknob.
Take 2 clamps and the safety cord out from the package and mount 2 clamps on the underside of fixture with 2 retainers attached
to each clamp. Hang the fixture on the structure and fasten the screws attached to each clamp. (See the WARNING on the
underside ofthe base as shown above) To pass the SAFETY CORD through the HOLES for safety! Always ensure that the
projector is firmlyanchored to avoid vibrationandslippingwhilstfunctioning. Alwaysensure thatthestructurethatyouaregoing

WARNING:
●The projectorMUSTbe liftedorcarriedbythe HANDLESinsteadofclamps.
●.Forsafetythesafetycord should afford10times the Projector’s weight.
●POWERCONNECTION

Note:Beforepowerconnection,pleaseensurethe powersuppliedmust matchwhatthenameplatesays.
●The earth wire(yellow/green) must be connected to the ground. And electrical connection must be in

●DMXCONTROLCONNECTION:
Connection between controller and projector and between one projector and another must be made with a twin-screened cable, with
each wire having at least a 0.5mm in diameter. Connection to and from the projector is via cannon 3 pin (which are included with the
projector)or3pinXLRplugsand sockets.The XLR'sareconnectedasshownin thefigureabove.
Note: care should be taken to ensure that none of the pins touch the metallic body of the plug or each other. XLR plugs and sockets
mustn’t be connected in any way other than mentioned in the above figure. The projector accepts digital control signals in protocol
DMX512(1990).
Connect the controller’s DMX output to the first fixture’s DMX input, and connect the first fixture’s DMX output to the second
fixture’s DMX input and connect the rest fixtures in the same way. Eventually connect the last fixture’s DMX output to a DMX
terminatorasshowninthe figurebelow.
●DMXTERMINATOR
In the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX terminator. This prevents
electrical noise fromdisturbingandcorruptingtheDMXcontrolsignals.
The DMX terminator is simply an XLR connector with a 120(ohm) resistor connected across pins 2 and 3, which is then plugged
intotheoutputsocketonthe lastprojectorinthechain.Theconnectionsare illustrated below.

6. SETUPANDCONFIGURATION
●FRONTPANELOPERATION
Projectorconfigurationcanbesetconveniently via pushbuttonandLCDdisplay.
Launch the projector and pressbutton ENTER for more than 3 seconds to unlock the panel, the LCD will show the function menu of
the projector, each main menu has its submenus and each submenu has a specific function. For details, please see the
“OPERATION MENU” section.

Pressbutton ENTER tosave your settingsorenter thesubmenu.
Pressbutton UP or DOWN tochangevalues(plusor minus)
Pressbutton FUNC,it willreturnto theupper menu.Ifbutton FUNC notpressed,thedefaultwillshowdisplaystatusautomatically.
●DMX STARTADDRESS
EachProjectormust be givena DMXstartaddressso thatthecorrectprojectorrespondsto the correct controlsignals.This DMX start
address is the channel number from which the projector starts to “listen” to the digital control information being sent out from the
controller. The Unit has 2 DMX modes. Thereare standard mode and extended mode. For example standard mode has6 channels,
so set the No. 1 projector’s address 001, No. 2 projector’s address 007, No. 3 projector’s address 013, No. 4 projector’s address019,
andsoon.

●DMXWIRELESSCONTROL(Iftheprojectorhasthefunction)
Theprojectorhaswirelesscontrol functionwith wirelessreceivermoduleandantennafor remotecontrol.
Thesetupofitisbelow:
1. Enter into the projector’s menu. Select the menu “Config Settigns” via the bottoms of UP and DOWN
2. Select DMX control Mode---- Wireless First (Note: do not select XLR ONLY),then wireless indication in the
front panel will beon, meaning wirelesscontrolfunction isactivated.
Only after the projector is linked with a transmitter, can it receive wireless signal sent by the transmitter. If unlinking it,
Press “Enter” for the menu of Unlink Wireless under the upper level menu of Config Settigns.

●STAND-ALONEMODE
Operate the projector without connecting with a controller, enable the master mode through the operation panel, the
projector will run in Stand-Alone mode automatically.
DMX address can be set at any number within 512.
●MASTER/SLAVEMODE
Many projectors can run synchronously in the Master/Slave mode by linking them with each other. First,
connect the first fixture’s DMX output to the second fixture’s DMX input using XLR-XLR controlcable and then connect the second
fixture’s DMX output to the third fixture’s DMX input, and so on until all projector are connected in this way. Eventually connect the
last fixture’s DMX output to a DMX terminator. Set 1st projector as the master and others are Slaves.
StartAddressesofall Slaves are 001; Operation mode of the Master can be set any mode for a Master’ and Slaves’ operation mode can
besetaccordingly.
AfterPoweredon,the group willruninMaster/Slave Mode
