Safety Issues: This unit may “pop” the fuse if the maximum allotted 
load of 2 amps is reached.
•  To reduce the risk of electrical shock or re, do not expose this unit
     rain or moisture.
•   Do not spill water or other liquids  into or on to your unit.
•   Do not attempt to remove or break o the ground prong from the
    electrical cord. This prong is used to reduce the risk of electrical  
   shock and re in case of an internal short. Do not attempt to oper-
   ate this unit if the power cord has been frayed or broken.
•   Disconnect from main power before making any type of connection.
•   Do not remove the cover under any conditions. There are no user  
   serviceable parts inside.
•   Always be sure to mount this unit in an area that will allow proper  
   ventilation. Allow about 6” (15cm) between this device and a wall.
•   Do not attempt to operate this unit, if it becomes damaged.
•   This unit is intended for indoor use only, use of this product out-
   doors voids all warranties.
•   During long periods of non-use, disconnect the unit’s main power.
•   Always mount this unit in safe and stable matter.
•   Power cords should be routed so they are not likely to be walked  
   on, pinched by items placed upon or against them.
• Cleaning -The fixture should be cleaned only as recommended by  
   the manufacturer. See page 24 for cleaning details.
•   Heat -The appliance should be situated away from heat sources  
   such as radiators, heat registers, stoves, or other appliances    
   (including amplifiers) that produce heat.
•   The fixture should be serviced by qualified service personnel when:
    A.  The power-supply cord or the plug has been damaged.
    B.   Objects have fallen, or liquid has been spilled into the unit.
    C.  The unit has been exposed to rain or water.
    D.   The unit does not appear to operate normally or exhibits a
            marked change in performance.
LASER RADIATION AVOID

 Boom Box FX1 Safety Precautions
NON-INTERLOCKED HOUSING WARNING
The Royal Sky contains high power laser devices internally. Do not 
open the laser housing, due to the potential exposure to unsafe levels 
of laser radiation. The laser power levels, if the unit is opened, can 
cause instant blindness, skin burns and res.
STOP AND READ ALL LASER SAFETY DATA
OPERATION INSTRUCTIONS AND LASER SAFETY
The light source emitted from this product can potentially cause eye 
injury if not set up and used properly. The light source emitted from a 
laser is very dierent from any other light sources with which you may 
be aware of. Laser light is thousands of times more concentrated 
than any light from any other kind of light source. This concentration 
of light can cause instant eye injuries, primarily by burning the retina 
(the back of your eyeball contatining cells that are sensitive to light). 
Even if you cannot feel “heat” from a laser beam, it can still poten-
tially injure or blind you or your audience. Even very small amounts 
of laser beam light are potentially hazardous even at long distances. 
Laser eye injuries can be sustained faster than you can blink.
Do not think that because this laser splits the laser beam into hun-
dreds of beams and that the laser beam is scanned out in high 
speed, that an individual laser beam is safe for eye exposure. This 
laser uses dozens of milliwatts of laser power (Class 3B levels inter-
nally) before it splits into multiple beams (Class 3R levels). Many of 
the individual beams are potentially hazardous to the eyes.
Do not that because the laser light is moving, it is safe. This is not 
true. Nor, do the laser beams always move. Since eye injuries can 
occur instantly, it is critical to prevent even the smallest possibility of 
any direct eye exposure. In the laser safety regulation, it is not legal 
to aim Class 3R lasers in areas which people can get exposed. This 
is true even if it is aimed below people’s faces, such as on a dance 
oor.
Do not operate the laser without rst reading and understanding 
all safety and technical data in this manual.
Always set up and install all laser eects so that all laser light is at 
least 3 meters (9.8 feet) above the oor on which people can stand.
