CONSUMER ALERT

Most  users  do  not  need  a  license  to  operate  this  wireless  microphone  system.  

Nevertheless, operating this microphone system without a license is subject to certain 

restrictions: the system may not cause harmful interference; it must operate at a low 

power level (not in excess of 50mW); and it has no protection from  interference received 

from any other device. Purchasers should also be aware that the FCC is currently 

evaluating use of wireless microphone systems, and these rules are subject to change.

For more information, call the FCC at 1-888-CALL-FCC 

(TTY: 1-888-TELL-FCC)

or visit :  www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html

Please note that wireless frequencies are shared with other radio services. 

According  to  FCC  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 or change frequencies. The above statement is valid only for 

use in the U.S.A.

If you encounter slight receiving interference when the transmitter is far from the 

receiver (from other than an operating TV station on the same frequency), it can 

often  be  overcome  by  relocating  the  receiver  to  a  different  place,  away  from  RF 

sources, e.g., TV, radio, computer, electric  motors. 

                    PRECAUTIONS AND TROUBLESHOOTING

Audio Feedback

Avoid  acoustic  feedback  (howling  or  screeching)  by  taking  care  in  selecting  P.A. 

volume, transmitter location and speaker placement.

[  Note:  the  pickup  pattern  characteristics  of  the  microphone  selected:  Unidirectional 

microphones are more resistant to feedback. However, they pick up sound sources best 

that are directly in front of the microphone. Mics that are farther from the sound source 

(such as a lavalier) require more acoustic gain and thus are also more prone to feedback 

than close-source Mics.] 

No Or Low Audio

If  you  are  not  getting  audio  through  the  system,  carefully  re-check  all  setups. 

Especially note that the receiver and transmitter must be set to operate on the same 

RF channel. 

Also confirm that the BODYPACK transmitter’s POWER SWITCH (17) is not in the 

MUTE/STBY position. The receiver’s UNBALANCED MIX OUT (8) is adjustable so 

make sure the VOLUME CONTROL (6) is set properly.

RF Interference and Finding Open Channels

The FCC mandates that the following information be provided to all users of this 

equipment:
