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.

PROBLEM SOLVING

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.)
