Wireless Microphone System Operating Manual
Fit an Alkaline AAA battery into the battery compartment, re-fit the lid and push the
sealed on/off button. A tiny blue LED illuminates to let you know it’s on. When that LED
starts flashing then the power is running low and it’s time to change the battery. One
AAA battery should supply over 5 hours of air time. Re-chargeable AAA batteries can
also be used.
6. REMARKS
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 must 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 un-
wanted 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.
