regulations, “Wireless microphone operations are unprotected
from interference from other licensed operations in the band. If any
interference is received by any Government or non-Government
operation, the wireless microphone must cease operation…” If you need
assistance with operation of frequency selection, please contact your
dealer or AmpliVox. Additionally There are models available for use in
Canada.
power soUrce
The transmitter and receiver are each operated by a 9V alkaline battery.
Before use, install a battery as shown. Make certain the battery is fully
seated in its compartment so the cover slides in place easily. Battery life
with alkaline batteries is approximately 8 hours of operating time. The
receiver also features an external jack for connecting a 9V DC power
supply (not included).
transmitter operation
If there is a “dead spot” in a room, try a slight change of position or try
changing frequencies. Each unit provides two selectable transmitting
frequencies.
1) Switch the Frequency Selector Switch to the desired channel
(A or B).
2) Belt clip on the back of the unit clips the transmitter onto a belt or
the transmitter simply can be put into a pocket.
3) Plug the microphone into the Mic Input Jack.
4) The microphone can be clipped to a necktie or other clothing, using
the supplied clip.
5) Slide the power ON/OFF switch to the ON position (the LED indicator
light will illuminate).
HelpFUl Hints
A) If the selected channel is noisy, switch both the transmitter and
receiver to the other channel.
C) Low ceiling fluorescent lighting, overhead telephone lines, or close
proximity to metal fences can all cause static. If this occurs, try a slight
change of position and/or try changing frequencies.
D) When the battery voltage drops below 6V, the LED indicator will go
out. This means you need a new battery.
E) Be sure to turn off the power whenever the units are not in use, and
remove the batteries if the units will be out of service for a long time.
F) Cellular telephones cause interference with the wireless mic. Please
ask your audience to turn off their cell phones.
NOTE: There are no user-adjustable parts inside the transmitter or
receiver Do not attempt to open or make any adjustments
belt clip
A detachable belt clip is included for convenience. Slide the tapered
end of the belt clip into the grooved area located on the back of the unit
until it clicks into place.

is the howl or screech often heard in sound reinforcement
systems. It is caused by sound from the loudspeaker returning to the
microphone. AmpliVox systems utilize proven acoustical principles
to minimize this; however, there is no way to completely eliminate
feedback under conditions of high amplification. If feedback occurs
check the following:
1. User’s hand covering the head of the microphone. (Hold microphone
under head slots.)
2. Sound can easily re-enter microphone. Keep loudspeaker turned
toward audience. Note: sound can be reflected from a hard surface
back through the microphone. (Turn speaker.)
3. User holding microphone in a reflecting position. (Turn microphone.)
4. Volume setting too high. (Reduce microphone channel volume;
compensate by speaking louder or closer to the microphone.)
