Connecting cables to hands-free unit HF-7
Power cable CA-60P
Plug the power cable into the corresponding port of the hands-free unit. The
wires in the cable harness are to be connected as shown in the wiring
diagram.
1. Connect the black wire to the vehicle ground (GND).
2. Connect the yellow wire to the MUTE connection of the car radio. When a
call is accepted, the car kit switches the yellow line (MUTE) to ground,
muting the car radio. When the call is ended, the yellow line is separated
from ground, and the car radio is unmuted.
If your car radio does not have a mute connection, this line may remain
unconnected. In this case, your car radio is not muted automatically during
a call.
An additional relay can be installed to switch the hands-free unit to the
loudspeakers of the car using the yellow line.
3. Connect the red wire to a suitable 12-V line controlled by the ignition key
using the 2-A fuse supplied (terminal 15, ignition sense cable, IGNS).
When you turn on the ignition of your car, you automatically switch on the
car kit. When the ignition is turned off, the car kit is deactivated. Note,
however, that this does not automatically turn the mobile phone in the
phone holder on or off, respectively.
