Tips on Using Classroom

Amplification

These helpful suggestions are provided to maximize the successful use of

your new LES 780iR Infrared Classroom Amplification System.

•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 amplification system provides adequate amplification (approximately 5 - 10 dB) above ambient room noises.

•Avoid wearing jewelry that may rub or bump against the microphone.

•Turn the LightMic off during private conversations with a student, parent, or other classroom visitor. You can also cover the LED lens on top of the LightMic to block the signal.

•Recharge batteries each night. When recharged nightly, operating time (actual usage) for the transmitters will last through a typical school day. Your rechargeable batteries will last for a normal school year when cared

for properly.

[ caution! ]

Do not attempt to charge alkaline

batteries̶they will overheat and expand, creating a significant hazard and damaging the transmitter. (This type of damge is not covered under warranty.)
