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.

FeedbacK

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.)
