I Recently purchased yet another Service Manual from Owner-Manuals.com, this time for a Sony EVS700ES/UB Videocassette Recorder. The Manual was available for upload within two hours and is an Extremely Good copy, as some of this I was able to enlarge to get even better detail.
Once Again, Very happy with the result!

INSTALLATION GUIDE
4.2.4 Installing the Handsfree Microphone
The following points should be considered when installing the handsfree microphone: That it does not obstruct the operation of the vehicle. That it does not affect the normal passenger accommodation. That the microphone should face the driver�s mouth, at a distance of approximately 30cm.
Mounting the Microphone to the Sun Visor
1. Mount the microphone onto the sun visor clip by inserting the projection of the clip into the hole of the microphone base. 2. Mount the microphone onto the sun visor as shown in figure 5. 3. Connect the microphone to the flying lead from the handsfree cradle.
Mounting the Microphone to the Dashboard
1. Attach the adhesive pad to the dashboard clip. 2. Drill a 1mm hole at the mounting location and mount the clip using a M2.5 self-tapping screw. 3. Insert the projection of the clip into the microphone base, ensuring that it points towards the driver mouth. 4. Connect the handsfree microphone to the handsfree cradle.
