Selecting a Location for the Microphone
The hands-free directional microphone must be properly positioned
in the vehicle to ensure optimum performance.
When selecting a location for the microphone, consider these
guidelines:
Mount the microphone near the centre of the vehicle, either on
•
the driver-side sun visor or on the head-liner above the driver.
Do not position the microphone where it may be blocked by the
•
visor.
Position the microphone so that it faces the user of the mobile
•
when the user is seated normally.
Do NOT position the microphone near a window or in any
•
location where road noise or any ambient background noise may
be high (above 85 dB SPL).
Do NOT position the microphone where it will be affected by the
•
output of the speaker (see below).
INSTALLING THE
DIRECTIONAL
MICROPHONE
NOTE:
The microphone should be installed in a location that is no
greater than 45cm / 1’6” away from the driver. Distance greater
than this will cause an attenuated voice level to be received.
