Tips for Optimum Audio Performace:
Speak in a natural voice: A normal conversational speech level will provide an adequate signal. It is not necessary to increase the intensity of your voice. The audio system provides adequate amplification above ambient room noises.
Avoid wearing jewelry that may rub or bump against the microphone.
Mute the Flexmike during private conversations with a student, parent, or other classroom visitor. You can tell the mic is muted when the light turns white.
Recharge microphones each night. When recharged nightly, operating time for the microphones will last through a typical school day.
