Read Before Use
Read the enclosed instructions and cautions thoroughly before using
this product. Failure to observe the proper use of this product could
result in voiding your warranty.
Note: The products pictu red here are for illustrat ion purposes and may not l ook
exactly like the product you have purchased.
Adjusting Your Microphone
Do not bend the boom of the
microphone. Bending the boom or
earhook sections of the microphone will cause breakage and
render the microphone inoperative. This is not covered under
warranty. The CO-3 should be
handled delicately.
Storing Your Microphone
When storing the CO-3, do not
wrap the cable in a tight loop or
coil the cable in any way that
creates serious bends or strain on
the cable.
Using The CO-3
Note: The products pictu red here are for illustrat ion purposes and may not l ook
exactly like the product you have purchased.
1. Remove the CO-3 from its case and
carefully uncoil the cable so that it is
fairly straight and without kinks or
bends.
2. The CO-3 is designed to be worn
over the left ear and is pre-fitted to
accommodate this. Press the curved
ear-hook area of the CO-3 evenly from
all sides to form a secure fit over the
left ear. Avoid over-bending the
earpiece.
3. Carefully adjust the “boom” portion of the CO-3 to curve
around the face. The capsule portion of the CO-3 is at the tip
of the boom. Curve the boom so that the capsule is located
as closely as possible to the mouth without touching
anything. This positioning will provide for an optimal signalto-noise ratio and will also minimize popping and the effects
of breath noise.
4. Position the CO-3 cable down the
neck area. Attach the enclosed
cable “clip” to the wire, and secure
the cable to the collar area, or an
area of clothing near the neck. This
will provide strain relief to the
microphone so that movement of
the boom is minimized to ensure a
consistent audio level.
5. Terminate your CO-3 microphone to a wireless transmitter
according to the connector type shown below. To find more
detailed information on how to terminate your microphone, or
if you need a different connector to terminate with any other
wireless systems, please visit our website at
www.point-sourceau dio.com/support.html.
Do NOT attempt to re-terminate the microphone yourself.
Making physical changes to the CO-3, such as changing the
cable termination or electronics, will void your warranty.
