IMPORTANT SAFETY INSTRUCTIONS

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.
