A more serious problem is selection of wireless-microphone operating frequencies
which are inherently subject to interference due to intermodulation. Fortunately, a
proper initial selection or changing frequencies will usually correct any such
problem. Vega offers a free computerized frequency-selection service to
purchasers of our equipment. If the frequency of other wireless equipment to be
used in a given area is known, interference-free frequencies can be chosen.
However, if equipment is added later without frequency coordination, it is likely
that an interference problem will occur. Should this happen, contact the Vega
factory or your sales representative for assistance. Many wireless systems may be
used in an area. However, careful frequency coordination is essential.
Microphone Problems
Almost all electret microphones are sensitive to RF energy and require special
precautions to operate properly with wireless transmitters. If the sound quality of
a microphone changes drastically when its position with respect to the transmitter
changes, it is likely that RF susceptibility is the cause. Contact the Vega factory
or your sales representative if assistance is required. Lavalier mics purchased
from Vega are specially assembled with added components to avoid this problem.
The wires in lavalier electret microphone cables are usually very small. After a
period of heavy use, the conductors may fray, resulting in intermittent failure or
severe noise. The wire also may break. It is advisable to have a spare microphone
available in good working condition (it does not need to be a high quality unit). A
spare microphone enables easy localizing of problems due to bad microphone
cables by merely substituting the spare for the suspected unit.
Warranty (Limited)
All Vega wireless products are guaranteed against malfunction due to defects in
materials and workmanship for one year, beginning at the date of original
purchase. If such a malfunction occurs, the product will be repaired or replaced
(at our option) without charge during the one-year period, if delivered to the Vega
factory. Warranty does not extend to damage due to improper repairs, finish or
appearance items, malfunction due to abuse or operation under other than the
specified conditions, nor to incidental or consequential damages. Some states do
not allow the exclusion or limitation of incidental or consequential damages, so
the above limitation may not apply to you. This warranty gives the customer
specific legal rights, and there may be other rights which vary from state to state.
Vega authorized service centers enable Vega to give customers immediate service
on repairs. These service centers are fully qualified and equipped to handle the
servicing of Vega equipment, and turnaround time is excellent. To obtain the
address of your nearest authorized warranty service center, contact your dealer or
the factory.
If you should require service, pack the equipment carefully and return it to the
factory service center or the nearest authorized service center.
Important: Be sure the exact return address and a description of the symptoms are
enclosed inside the package with your equipment.
It is also advisable to return the transmitter and receiver for full system
performance test when practical.
