A more serious problem is selection of wireless-intercom operating frequencies, which are
inherently subject to interference due to intermodulation. Fortunately, a proper initial selection of
or changing frequencies will usually correct any such problem. Vega offers a free computerized
frequency-selection service to purchasers of its 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, an interference problem
will likely occur. Should this happen, contact the Vega factory or your sales representative for
assistance.

General

It is best to contact the Vega factory or your sales representative prior to returning equipment
for repair. Oftentimes, the problem can be resolved by telephone, avoiding downtime for
unnecessary returns. However, should repairs be necessary, Vega will promptly correct the
problem and return the 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, or malfunction due to abuse or operation under
other than the specified conditions, nor does it extend to incidental or consequential damages.
Some states do not allow the exclusion or limitation of incidental or consequential damages,
so the above limitation might not apply to you. This warranty gives the customer specific
legal rights, and there might be other rights which vary from state to state.

Vega's 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 to the nearest authorized service center.

IMPORTANT: Be sure your exact return address, name and telephone number, and a
description of the symptoms are enclosed inside the package with your equipment.

It is essential to return the entire system for a full system performance test, if at all practical.
