microphone's display. Buttons you press appear in
bold type and text that appears on the display
appears in italic type.
How The Microphone’s Controls Appear
in This Manual
To help navigate the microphone's menus, the steps
shown in this manual describe the displays you see
and the keys you press or control you operate to get

Engine Noise Suppression
Interference from the noise generated by the
electrical systems of engines is sometimes a
problem with microphones. Your microphone has
been designed to be essentially impervious to
ignition noise and alternator noise. However, in
some installations it may be necessary to take
measures to further reduce the effect of noise
interference.
In severe cases of noise interference, it may be necessary to install a noise suppression kit. Contact the
dealer where you purchased the microphone for
more information.
