Directly to your hearing aid (when equipped with a Phonak MicroLink or other type
216MHz receiver)
To your personal transmitter and FM receiver
To an earphone or neckloop
To an optional speaker

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.
