4. ENSURE THAT NORMAL CONTROL AND OPERATION OF THE VEHICLE IS NOT IMP AIRED BY THE INST ALLATION, P ARTICULARL Y THE
BRAKES AND STEERING. ENSURE THA T AIRBAG OPERATION IS NOT
OBSTRUCTED.
5. ELECTRONIC AND OTHER SOPHISTICATED SYSTEMS (e.g. SPEED
CONTROL, ABS ANTI–LOCK BRAKE, FUEL INJECTION–, NAVIGATION–, AND AIR–BAG SYSTEMS) ARE RELA TIVEL Y IMMUNE T O MALFUNCTION CAUSED BY NEARBY RADIO TRANSMISSIONS. HOWEVER, SHOULD YOU EXPERIENCE FALSE OPERATION OF THESE
SYSTEMS OR ARE IN ANY DOUBT WHA TSOEVER AS TO THEIR FUNCTIONALITY, PLEASE CONSULT THE VEHICLE’S DEALER.
6. THE CAR KIT IS SUIT ABLE FOR USE ONLY IN VEHICLES WITH A 12 V
NEGA TIVE GROUNDING. USE ON OTHER SUPPLY VOLTAGES OR ALTERNATIVE POLARITY WILL DAMAGE THE EQUIPMENT.

Component Parts
Advanced Active Holder MCC–1
The holder allows the phone to be firmly located in a convenient position.
The holder is attached to the vehicle’s interior using the swivel mount
HHS–9. The mounting must be secured with a screw (included with
HHS–9). The screw recess can then be covered with the NOKIA logo
plate.
Advanced HF Unit HFU–2
The handsfree unit enables the phone to operate in handsfree mode.
The unit is attached to the vehicle interior using the mounting plate
MKU–1. The mounting must be secured with a screw (included with
MKU–1). A temporary installation can be achieved using installation belts
(not supplied).
Power is supplied from the vehicle’s battery via the power cable PCH–4J.
The handsfree unit provides the power supply to the phone via the system connector.
Technical Documentation
The HF microphone HFM–8, connects to the
MIC socket. And the HF
speaker HFS–12, connects to the socket.
Mounting Plate MKU–1 and Swivel Mount HHS–9
MKU–1 is a fixed position mounting plate; HHS–9 is a swivel mount which
allows for adjustable fixing. The two mounting plates are interchangeable.
HF Microphone HFM–8
The HF microphone connects directly to the handsfree unit (
MIC socket).
Insert the plug into the MIC socket and twist 90° to lock firmly in place.
HF Speaker HFS–12
The HF speaker connects directly to the handsfree unit (
Insert the plug into the
socket and twist 90° to lock firmly in place.

Power Cable PCH–4J
The power cable connects the standard handsfree unit HFU–2 to the vehicle’s power supply. 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 controlled by the vehicle’s ignition key via the supplied fused connector.
See section ”Ignition Sense”.
The yellow wire is used for car radio muting (XCRM). The line goes down
to 0 volts during a call. See section ”Car Radio Muting”.
The green wire is used for motor antenna (AMC). The voltage in this output is +12 V whenever the phone is on. See section ”Antenna Motor Control”.
External Mobile Antenna (not supplied)
CARK–91
The cellular phone is designed to operate with a high quality external antenna. However, due to many different types of antennas being available,
an antenna is NOT included as part of this kit. Please, consult the dealer
to find out which is the most suitable antena type for your installation.

Installation
There are some important aspects that require special attention in positioning car kit accessories.
The positioning of the phone holder is the most important factor when trying to achieve the most comfortable position for the user. The location of
the holder should be selected so that the visibility of the phone’s display is
good under all lighting conditions, but not so that the driver’s attention is
easily distracted. The holder should be located so that the driver can easily reach the keypad. Under no circumstances should the holder prevent
the driver from controlling or operating the vehicle in any way or observing traffic.
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.
Technical Documentation
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 ignition sense feature prevents your car kit from draining the car battery by executing an auto power off in 20 seconds after the ignition key
has been turned off. The blue wire of the power cable is used for the ignition sense feature. The use of ignition sense is recommended to prevent
accidental draining of the car’s battery. The wire is connected via a 1 A
fuse to a 12/24 volt potential that is controlled by the ignition key. Do not
connect it directly to the high voltage sections of the ignition circuit.
Car Radio Muting CRM
The car kit offers a feature that can mute the car radio automatically during a conversation. This feature is convenient and provides for safer
handsfree operation. The car radio muting feature is based on a
grounded line, so it means that in standby, the yellow wire (XCRM) is not
grounded and car radio works normally, but during a call, line is grounded
and car radio is muted. Note that an auxiliary relay or muting unit must
be used when the car radio doesn’t have a mute feature available.
CARK–91
When a relay is used, connect of series with the car radio main supply. A
200 mA fuse should be used to protect the XCRM output in event of a
short circuit. Some radios have separate supplies for amplifiers and motors, 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), but to install
the relay in the main supply feed.

Another possibility is to use a special muting unit, which mutes the radio

Antenna Motor Control AMC
The antenna motor control offers a feature, green wire of the system
cable (AMC), that may be used to control different devices on and off.
The voltage in this output is +12 V whenever the phone is on. If the phone
is turned off, the voltage disappeares. The maximum output current is 200
mA, therefore for example motorized antenna must be controlled via a
relay, see picture below.

All installations should take into account any special requirements of the
customer. However, should the customer require an installation that is
illegal or unsafe these facts must be pointed out to the customer and a
policy of non–compliance adopted.
Testing
Once installed, the equipment should be tested to ensure that it is operating satisfactorily and that the position of the units does not impair on the
driver’s ability to control and operate the vehicle in any way.
Use the phone to make a call when the vehicle is parked with the engine
running. During the call, switch off the engine. Ensure that the phone is
operational with the engine running and with the engine switched off. For
operating information refer to the User’s Guide supplied with the phone.
