Maintain distance between the calling radio and the Loudmouth

In general, the calling radio should be at least 50 feet away from the speaker when the Loudmouth

 is set for 

50% volume.  The necessar

Y

can also reduce feedback. 

 

Use a noise canceling microphone 

Equip your calling radio with an optional noise-canceling microphone. 
 

Record and Play feature eliminates feedback 

The Record and Play feature completely eliminates feedback by recording your 

message and playing it back immediately after you have finished sending it to the 

Loudmouth

 receiver.   See page 18 to enable the Record and Play operation. 

The calling radio is not transmitting while the message is broadcast, so speaker 

audio cannot get into the calling radio microphone.
