HF Microphone HFM-8
The HF microphone should be installed according to the directions in the separate microphone installation guide. Ensure the microphone is as close to the driver�s mouth as possible, and attached to a surface that is mechanically quiet. The microphone should be mounted at least 3 ft./1 m away from the handsfree unit speaker to avoid acoustic feedback. Insert the HFM-8 plug into the MIC socket in HFW-1 and twist 90° clockwise to lock firmly in place.

HF Speaker HFS-12
Install the HF speaker so that it is at least 3 ft./1 m away from the HFM-8 microphone to avoid acoustic feedback. Insert the HFS-12 plug into the SPEAKER socket and twist 90° clockwise to lock firmly in place. Under no circumstances should the HFS-12 prevent the driver from controlling or operating the vehicle in any way or observing traffic.

The power cable connects the wireless handsfree unit HFW-1 to the vehicle�s power supply (DC socket). The red wire must be connected to the + voltage on the vehicle�s power supply via the supplied fused connector. The black wire must be attached to a good negative GND connection. The blue ignition sense (IGNS) wire is connected to +12 V voltage con trolled by the vehicle�s ignition key via the supplied fused connector. See section "Ignition Sense". The yellow wire is used for car radio muting (CRM). The line goes down to 0 volts during a call. See section "Car Radio Muting".
