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.

START OF THE DAY

Turn the

microphone

ON using the

ON/OFF switch

on the side of

the REDMIKE

and speak

normally. Set

the channel

switch to A.

Return the

REDMIKE to

the cradle

charger and

recharge the

REDMIKE at

the end of

the day.

Remove the REDMIKE

from the charger and

place it around your

neck. Adjust the neck

strap so the top of the

microphone rests just

below your collarbone.

CONGRATULATIONS!

Congratulations on your purchase of the 705iR Portable Infrared

Audio System! Please take a moment to review this manual, as it will help

you operate this easy-to-use system, and maximize your investment by

caring for and maintaining each component.

The 705iR is a lightweight, multi-purpose, portable audio system powered

by rechargeable batteries or AC power. It is designed to allow teachers to

speak in normal conversational tones and yet be heard clearly by every

student in the classroom.

The 705iR comes standard with the REDMIKE™ pendant-style

classroom microphone. The system may be used with two microphones

accommodating team teaching or student interaction. The second

microphone can be an additional REDMIKE, LT-71 or the HM-70 handheld

microphone.
