Microphone HFM-8 (Pos.6)
Note: The use of any microphone other than that supplied may impact the transmission
quality.
Mount the handsfree microphone approx. 30 cm from the user's head, and position it so
that it points towards the user's mouth. Experience has shown that the best locations are
near the rearview mirror or to the left of the sun visor (for lefthand drive vehicles) / to
the right of the sun visor (for righthand drive vehicles). Make sure to keep the micro-
phone a minimum distance of 1 metre away from the car phone loudspeaker to avoid
feedback.
Take care to mount the microphone so that it is not exposed to air streams from the
vents. Microphone cable must not be laid in the heating, ventilation or AC system. Use
double-sided adhesive tape to fix the microphone as this will prevent noise from the car
body being transmitted into the interior.
When an incoming call is accepted or an outgoing call is connected, the system will
automatically mute the car radio and the call will be switched over to the CarKit Phone
loudspeaker.
Power Cable PCU-4 (Pos.5)
The power cable connects the CarKit phone to the car's electronics system. See the wir-
ing diagram for exact instructions.
Wiring guidelines
When laying the cables, care should be taken to position them so that they are located
as far as possible from the electronics systems installed in the car in order to avoid elec-
tromagnetic interference.
Also ensure that cables are placed so that they will not be subjected to mechanical wear
and tear (e.g. not laid under car seats or over sharp edges).
GSM Antenna (Pos.7) (not included in the sales package)
The CarKit Phone is designed to be connected to an external GSM antenna. However, if
the car is equipped with a radio/GSM antenna with a frequency separating filter, this
may be used instead.
If the car does not have a GSM antenna, contact the relevant dealer for information on
the best location and for the relevant installation guidelines.

Audio settings

The CarKit Phone supports a variety of options for output over a loudspeaker.
• Direct connection to the supplied SP-2 loudspeaker.
• Connection to a compatible car radio loudspeaker over an additional relay that
switches audio output over to the loudspeaker.
