The HFW-1 is used in a fixed car installation and it offers a
wireless handsfree function, a fast charging function when a
phone is connected into i t by a cha r gi ng c abl e (ph one spe ci fic ,
not supplied with CARK-112) and a wireless connection to
external devices.
The HFW-1 unit is attached to the vehicle interior using the
mounting plate MKU-1. HFW-1 is secured to MKU-1 with a
screw (included with MKU-1).
Power is supplied to DC socket from the vehicle’s battery via
the power cable PCU-4.
The HF microphone HFM-8, connects to the MIC socket. And
the HF speaker HFS-12, connects to the SPEAKER socket.
PHONE socket is for the charging o f the phone (charging cable
phone specific - not included with car kit).
The HFW-1 is always connected to a car battery. To save the
car battery the HFW-1 goes to a sleep mode. Sleep mode is
activated if: 1. the car is not running and a phone is not connected by a charging cable and there is no wire less traf fi c or 2.
charging of the phone has been stopped.
Installation
After tightening the MKU-1 screws, secure HFW-1 installation
to the MKU-1 mounting plate with the screw going through
HFW-1. The Nokia logo lid is placed on the HFW-1 to cover the
recess.
5
Do not install the HFW-1 unit in a metal casing (or similar location) that can prevent the unit from transmitting radio frequencies. Aim the internal Bluetooth antenna (see picture) towards
the user (Bluetooth phone).
Mounting Plate MKU-1
MKU-1 is a fixed position mounting plate. It is used to attach
Wireless HF Unit (HFW-1) to the vehicle.
Remote Control Button CUW-2
The Remote Control Button (CUW-2) allows convenient operation of the phone. The car installation includes a Remote Control Button CUW-2, which is connected to the HFW-1 with a
cable (REMOTE socket). The speaker volume of the HFW-1
can be controlled with a ring (rotary switch) in the CUW-2. It is
possible to recei ve a c all or to dial b y press ing a s end/end push
button in the CUW-2 (also voice diali ng).
To read more about the use of CUW-2, see CARK112 User’s
Guide.
Installation
The positioning of the Remote Control Button CUW-2 is important, to achieve the most comf ortable position for the user. The
location of the CUW-2 should be selected so that the visibility
of the Remote Control Button is good under all lighting conditions, but not so that the driver’s attention is easily distracted.
The CUW-2 should be located so that the driv er can easi ly
reach it. Under no circumstances should the CUW-2 prevent
the driver from controlling or operating the vehicle in any way
or observing traffic.

HF Microphone HFM-8
The HF microphone should be installed according to the directions in the sep arat e m ic rop hon e i ns t al lat ion gu ide . En su re 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.

Power Cable PCU-4
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 s up pli ed fused connector. The black
wire must be attached to a good negative GND connection.
The blue ignition sens e (IG NS) w ire is co nne cte d to +12 V vol tage 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 ca ll. See sec tion "Car R adio Mu ting".

Cables
Ensure cables are routed as far away as possible from the
vehicle’s electronic systems (refer to WARNINGS)*. Also,
ensure that cables are not subjected to undue mechanical
stress e.g. under seats or against sharp edges.
* To prevent disturbance, cables should be routed as far away
from the interference source as possible.
Ignition Sense IGNS
The blue wire of the power cab le PCU-4 is us ed for the ignition
sense feature. The use of ignition sense is recommended to
prevent accidental drain ing of the c ar’s battery and mak in g the
automatic connecti on to the phone. The wire is co nnected via a
1 A fuse to a 12 volt potential that is controlled by the ignition
8
key. Do not connect it directly to the high voltage sections of
the ignition circuit.
Car Radio Muting CRM
The car kit offers a featu re that c an mut e the ca r radio a utoma tically during a conversation. The car radio muting feature is
based on a grounded line, so it means that in standby, the yellow wire (CRM) is not grounded and car radio works normally,
but during a call, line is grounded and car radio is muted.
Some radios have se parate s uppli es for am plifi ers an d moto rs,
and another for memory backup purposes. Very often these
radios also have a secret code system, which activates itself if
a break in the memory supply is detected. Be careful when
installing the relay not to break the memory supply (usually
marked ACC or +MEM)..
