Vega R-662A PRO PLUS, Руководство пользователя, Страница: 3 / 17

Vega UHF wireless microphones operate in the radio frequency band from 494 to
608 MHz, and from 614 to 806 MHz. These systems must be licensed by the
FCC before operation. There are some restrictions on the issuance of such
licenses; if you are not aware of the rules for licensing, contact your Vega sales
representative or the Vega factory.
Compatibility
The Vega Model R-662A PRO PLUS DYNEX
®
III UHF diversity receiver is
designed to work with Vega T-677 Series PRO PLUS DYNEX
®
III UHF
bodypack wireless microphone transmitters or T-680 Series handheld transmitters.
If the transmitter was not purchased with the receiver, it is not necessarily
compatible. Call the Vega factory or your Vega sales representative if you are not
certain the transmitter and receiver are compatible. Generally speaking, Vega
receivers will not function properly with transmitters manufactured by other
companies.
Operating Frequencies
The R-662A receiver is designed to work in the 494-to-608-MHz and 614-to-806-
MHz UHF ranges and must be precisely matched to the frequency(ies) of the
associated transmitter(s).
The R-662A receiver is available with up to four switch-selectable operating
frequencies installed. The operating frequencies are marked on the data label on
the bottom of the receiver.
If more than one frequency is installed in the receiver, the receiver operating
frequency can be changed in the field by means of a rear-panel-mounted rotary
switch. This allows the receiver to be tuned easily to any one of up to four T-677
Series bodypack transmitters or T-680 Series handheld transmitters. Consult your
Vega representative for assistance in selecting compatible frequencies to install in
the receiver.
The T-677 Series bodypack transmitter and T-680 Series handheld transmitter are
available tuned to a single frequency. If the transmitter and receiver frequencies
are not precisely the same, the frequency of one of the units must be changed. It's
usually easier to change the frequency of the transmitter; however, it is advisable
to return both units to the factory or authorized service location when changing
frequencies, to ensure the best results.
Because of the very high performance of these units and the specialized test
equipment required to adjust them properly, it is not recommended that users
attempt to change frequency themselves.
If two or more systems are to be used in the same location, proper frequency
selection and spacing are required to avoid possible interference. Vega offers a
free frequency-coordination service for purchasers of our equipment. Frequencies
are selected by computer to avoid any possible interference from other wireless
systems and broadcast stations.
Individuals wishing to take advantage of this free service should contact the Vega
factory or their local Vega sales representative.
