5.3 Visor Microphone Installation
1. Carefully select the installation location for the visor-mounted microphone. Achieve optimum
performance of the microphone’s hands-free circuitry by mounting the microphone in one of two
locations:
• on the sun-visor directly above the driver, or
• on the headliner just above the driver.
The microphone should never be mounted near the window or in a place where the road and ambient
background noise would be substantially high (above 85 dB SPL).
5.3.1 Connecting to the Mobile Radio
The visor-mounted microphone cable connects to a 16-pin connector block (part of the hardware
supplied): one wire connects to pin 2, and the other wire connects to pin 7 (Figure 5.3).
