DAILY REDMIKE USE
TURN ON THE REDMIKE
CHARGE BATTERIES
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 amplication (approximately 5 – 10 dB) above
ambient room noises.
Avoid wearing jewelry that may rub or bump against
the microphone.
Turn the REDMIKE off during private conversations with a
student, parent, or other classroom visitor. You can also cover
the LED lens on top of the REDMIKE 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.

      If you are experiencing no sound from the speaker of your Lightspeed Stereo System, here are a few things to check: * First, ensure that the 705iR is turned on and that the POWER light flashes RED once when you turn it on. * Next, confirm that a signal is being received at the 705iR. The IR signal light will be GREEN, indicating a signal is being received from the microphone. * Finally, verify that the REDMIKE is turned on.

      If your Lightspeed Stereo System is experiencing low volume or feedback, consider the following: * Make sure the pendant style microphone is correctly positioned just below the collar bone. * Also, check the volume level on the amplifier.
