allows them to be worn as a lavalier, or hidden
in loose clothing. For normal lavalier use, attach
the microphone about 6" (15 cm) below the
user’s chin. Anticipate movements that may
cause the microphone to rub against or be
covered by clothing and position the microphone
to avoid it.
Note: The MT830cW-TH microphone’s beige
“theater” color permits easy concealment.
