Using the boom microphone accessory
A directional boom (headset) microphone is supplied with your system as a
standard accessory. The boom microphone picks up speech very closely, improving
performance in noisy environments, and will help to avoid any acoustic feedback.
Plug the microphone into the 3.5mm
microphone
input jack on the top of the
transmitter [12]. Note that if the microphone is inserted into the auxiliary input
jack speech will not be amplified. Place the frame earhooks [33] over your ears and
adjust the boom arm to position the mic capsule [35] to point to the corner of your
mouth. It is not necessary to place the microphone in front of your lips and doing so
may diminish sound quality. The boom microphone frame can be adjusted to rest
comfortably over both ears, with no other contact or pressure points against the
head or face.
Using the handheld transmitter / microphone
To turn the handheld transmitter ON, press the power button [25] for 2 seconds.
The display will show the transmitter channel selection and the battery status. To
turn the transmitter OFF, press and hold the power button for 2 seconds. There is
a separate MUTE button [21] located on the back of the handheld transmitter. The
mute button will be lit by a green indicator when the transmitter is in TALK mode,
and by a red indicator when it is muted.
The microphone capsule of the handheld transmitter [20] is highly directional. Hold
the microphone close and pointing directly towards the mouth for best acoustic
performance.
