Wireless Microphone System Operating Manual

6. REMARKS
The V Series Receiver
Your receiver comes with 3 VHF channels to choose from. In the USA these are the travelling
frequencies around 169MHz and 4 channels elsewhere in the world ie UK 175MHz.
The single frequency transmitter supplied will match one of these channels. If it does not
work well on the frequency supplied then please contact your supplier to exchange for a
different channel transmitter.
RF Interference
If you encounter receiving interference (from other than an operating TV station), it can
often be overcome by adjusting the receiver’s squelch control, as described below. Please
note that wireless frequencies are shared with other radio services, and according to FCC
regulations wireless microphone operations are unprotected from interference from licensed
operations in the band. If any interference is received by any Government or
non-Government operation, the wireless microphone must cease operation. (The above
statement is valid for the U.S.A.)
Receiver Squelch control
The squelch control on the back panel of the receiver is preset at the factory, but can be
adjusted if you use the system in a high RF interference area. If there is audio output from the
receiver when your transmitter is OFF, adjust the squelch control so the system will receive
the signal from your transmitter but squelch or eliminate the unwanted background RF noise.
This adjustment can cause a reduction in usable range of the wireless transmitter, so set the
control to the lowest position which reliably mutes the unwanted RF signal.
Batteries
Many batteries are known to leak conductive and/or corrosive liquid when not used for a
period of time. Please remove the batteries from the transmitter if it is not to be used for a
period of a few days or more.
Multiple Transmitters
Please note that you can only use one mic transmitter at a time with the FA Series Receivers
so make sure that all other transmitters on the same frequency are turned off.
