216MHz receiver)

Important Notes About Your MicroField

MicroField is a highly versatile product. It can receive various types of audio signals and

uses a variety of methods to convert the signals to a form you can use. The unit can re-

transmit the signals directly to an FM or external receiver; it can send audio to a headset or

an optional loudspeaker; or it can send audio signals via auxiliary connections to an exter-

nal transmitter that transmits to an FM receiver.

This manual frequently refers to “receive” and “transmit” channels. Please note that “re-

ceive” channels are frequencies received by MicroField from a portable, stationary or infra-

red transmitter in a room. A “transmit” channel is a channel MicroField uses to transmit to

your MicroLink, MicroEar or other FM receiver.
