2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this apparatus near water.

6. Clean only with a dry cloth.

7. Do not block any ventilation openings. Install in accordance with manufacturer’s

instructions.

8. Do not install near any heat sources such as radiators, heat registers, stoves, or

other apparatus that produce heat.

9. Only use attachments / accessories specified by the manufacturer.

10. Use only with a cart, stand, bracket, or table

specified by the manufacturer or sold with the appara-
tus.   When a cart is used, use caution when moving
the cart / apparatus combination to avoid injury from
tip-over.

11. Refer all servicing to qualified service personnel. Servicing is required when an

apparatus has been damaged in any way, such as power-cord or plug is dam-
aged, liquid has been spilled, or objects have fallen into the apparatus, the appa-
ratus has been exposed to rain or moisture, does not operate normally, or has
been dropped.

12. To reduce the risk of fire or electric shock, do not expose this apparatus to rain 

or moisture.

13.  Hearing damage, prolonged exposure to excessive SPL, the loudspeaker 

is easily capable of generating sound pressure levels (SPL) sufficient to 
cause permanent hearing damage to performers, production crew and 
audience members. Caution should be taken to avoid prolonged exposure 
to SPL in excess of 90 dB.

The VRX Series loudspeakers covered by this 
manual are not intended for fixed installation in 
outdoor or high moisture environments. Moisture 
can damage the speaker cone and surround 
and cause corrosion of electrical contacts and 
metal parts. Avoid exposing the speakers to 
direct moisture. Keep speakers out of extended 
or intense direct sunlight. The driver suspension 
will prematurely dry out and finished surfaces may 
be degraded by long-term exposure to intense 
ultra-violet (UV) light. 

The VRX Series speakers can generate considerable
energy. When placed on a slippery surface such as
polished wood or linoleum, the speaker may move
due to its acoustical energy output. Precautions
should be taken to assure that the speaker does not
fall off a stage or table on which it is placed.
