setting FM volume

Follow steps 1 or 2 below to adjust FM volume setting to proper level. Two people are needed to set the volume level. It is difficult to hear your own voice and make adjustments to it.

NOTE: The average volume setting is in the 11:00 position (see photo), but may change depending on room acoustics and noise level.

1With a sound level meter - Take a level reading in the “A” setting in the center of the room during normal classroom activity, and another reading of the teacher's amplified voice (without the class activity). The level of the teacher's voice should be set between 10-15 decibels above room noise level.

2Without a sound level meter - First, ask someone other than yourself (if you are the teacher) to listen to the amplified voice and make volume adjustments. An ideal volume level is achieved when the listener can hear the amplified voice at a comfortable level and the vol- ume level from the speaker and teacher’s mouth is comparable. If you can hear yourself through the loudspeakers, the volume setting may be too high and should be decreased. 28
