For testing purposes, basic instructions for wearing and operating the LightMic are provided below. For more detailed instructions, refer to page 11.

•Clip the LightMic to the lavaliere.

•Place the LightMic and lavaliere cord around your neck and adjust cord length so the top of the LightMic sits just below your collar bone.

•Slide the ON/OFF switch on the LightMic to ON. The red power indicator will light.

•Slide the channel select switch to “A.”

7.Testing

Test the system to ensure everything is correctly connected and working proper- ly before your first full day of use. A second person is helpful to listen and ensure your voice is clear but not loud.

•With the LightMic positioned properly around the neck, speak normally and turn the A VOLUME clockwise until an optimum voice level is achieved. You may not be able to hear your own voice when this is properly set. However, your students will.

[ note: ]

The system can generate feedback (a squealing or howling sound) if there is too much volume or the equalization (EQ) levels are incor- rectly set. Adjust the three EQ level knobs if necessary to eliminate feedback and to obtain a natural sound.

•With volume and EQ levels set, walk around the room, paying special attention to the areas farthest from the IR sensor. Your voice should remain clear and intelligible.

•Consult the troubleshooting guide for further assistance.
