Component Parts
Mounting Bracket MBE–2
The mounting bracket MBE–2 shall be installed using three screws. The
bracket itself can to a certain degree compensate for unevenness of the
mounting surface. However, should additional spacers be required, two
different types are supplied with the bracket.
The transceiver may be installed in the bracket in two ways: either by
sliding the transceiver into the bracket or by vertically inserting the
transceiver from the top.
Handset Cradle CRE–1
The cradle CRE–1 acts as a holder for the handset. The cradle is attached
to the vehicle interior using mounting plate MKE–1 or swivel mount
HHS–1.
Mounting Plate MKE–1 and Swivel Mounting Plate HHS–1
MKE–1 is a fixed position mounting plate; HHS–1 is swivel mounting plate
which allow adjustable fixing of the CRE–1 cradle. Both mounting plates
are interchangeable.
System Cable SCM–1/SCM–3 and Vehicle Installation Cable DKS–3
The system cable connects the phone to the vehicle supply and
accessories. The long System Cable SCM–3 is optional.
The power wires red (+) and black (–) shall be routed to the battery itself
(alternatively to the main distribution point of the vehicles fuse box) both +
and – must be fuse protected (3 A).
The blue ignition sense (IGNS) wire is connected to +12 V voltage
controlled by the vehicle’s ignition key via the supplied fused connector.
The ignition sense can utilize voltages up to 24 V, see section ”Ignition
Sense”
The yellow wire is used for car radio muting (XCRM). The line goes down
to 0 volts during a call. The maximum sink current is 250 mA, hence the
actual muting operation may have to by done using an auxiliary relay, or a
muting unit provided by the manufacturer, see ”Car Radio Muting”.
The orange wire is used for motor antenna (ANTC). The voltage in this
output is +12 V whenever the phone is on. The maximum sink current is
200 mA, so the actual motor antenna operation may have to be done by
using an auxiliary relay, see ”Power Antenna Control”.
The RJ45 handset connector is performed by non–assembled. Locate the
correct position, fasten the bottom shell with two screws, place the
connector and cable and click the top on.

Handsfree Microphone HFM–14 and Handsfree Speaker HFS–10
The safest and easiest way to have call while driving is use the handsfree
option. The system consist of two components, the microphone HFM–14
and loudspeaker HFS–10.
The handsfree microphone can usually be installed on the drivers sunvisor
or A–pillar. The main idea is to get the microphone as close to the drivers
mouth as possible, and to attach the microphone to a surface that is
mechanically quiet. The microphone connects to the system cable MIC
molex connector.
The loudspeaker should be mounted at least 3 ft/1 m away from the
handsfree microphone to avoid acoustic feedback. The loudspeaker
connects to the system cable SPEAKER molex connector.
External Mobile Antenna (not supplied)
The 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 car kits. Please, consult the dealer to
find out which is the most suitable antenna type for your installation.
External SIM Card Reader
The CAE–2 is installed using a extension cable which is plugged into one
of the modular connectors on the card reader and into the connector on
the system cable normally used for the handset. The handset is then
connected to the second modular connector on the card reader. After
power up the system is ready for insertion of a SIM card. The SIM card is
inserted with the arrow on the SIM card facing the light guide for the LED
on the CAE–2. If the card is inserted upside down it will be rejected by the
card reader, and the message CARD REJECTED is written in the display
of the handset. If this happens, draw out the SIM card and insert it in the
right way.
Installation
There are some important aspects that require special attention in
positioning mobile phone accessories.
The positioning of the handset 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 handset’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 phone mounting bracket may be installed in a variety of places
including:
Ensure the location does not subject the phone to moisture or mechanical
pressure or where there isn’t adequate amount of air for cooling (under
the carpet, etc.).
. centre console below dash on either left or right side
.any available shelf above or below dash
.vacant DIN slot (consumes only half the height of a DIN slot)
.under seats
.trunk (with use of the SCM–3 system cable)
The handsfree microphone can be installed on the driver’s sunvisor or the
A–pillar. 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. Ensure the microphone gain
setting is in nokia position (default setting) with PCLocals or with handset
by entering command xxxx and M.
The loudspeaker isn’t so sensitive for vibrations, thus it can be located
more freely. The main idea is to optimize two requirements: The driver
should hear the signal from the loudspeaker without any special efforts,
but attenuation between loudspeaker and microphone should be as high
as possible, i.e. they must ”look” in other directions in order to minimize
the acoustic feedback.
Ensure cables are routed as far away as possible from the vehicle’s
electronic systems (refer to WARNINGS). Also ensure cables are not
subjected to undue mechanical stress e.g. under seats or against sharp
edges.
The most important component of the installation is the antenna. The
location of the antenna as well the quality of the antenna and its
installation have a considerable influence to the overall performance of the
whole system. Therefore it is necessary to emphasize some aspects,
which too often have caused unnecessary service work.
The best place for the antenna is the rooftop. The overall performance of
a rooftop antenna is clearly superior to any other antenna type or location.
The Antenna shall be mounted in a position such that no part of human
body will normally rest too close to any part of the antenna unless there is
a an intervening metallic screen, for example, the metallic roof.

After drilling the hole for the antenna remember to clean the hole from the
drilling swarf, so that surface is even. This is needed in order to ensure
proper and reliable connection between the ground plane and the
antenna. After cleaning it is advised to apply some rust–proofing
compound to the hole.
Mount the base of the antenna tightly in position. Consult the antennas
manual for determining the maximum bending angle before attempting
any bending operation.
To avoid drilling a hole in the vehicle’s bodywork, a glass–mounted
antenna can be chosen and located on the rear window of the vehicle.
Try to route the antenna cable so that possible sources of disturbances
are avoided, as well anti–skid brake systems. The shorter the antenna
cable, the smaller the attenuation, and the better the performance of the
antenna. The antenna coupler should always be connected to the antenna
via a non–radiating cable (e.g. coax).
Most of the antennas today have adapted the mini–crimp connector
system which eliminates the need for special crimping tools and
connectors. If however the purchased antenna has traditional connectors,
use only proper connectors and tools. The phone uses mini a UHF female
type antenna connector for reasons of reliability and attenuation.
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.
Power Distribution
The main supply for mobile phone is obtained from the vehicle battery, the
supply voltage may vary between 11 and 16 volts. Both the positive
voltage and the grounding are taken directly from the battery, unless the
vehicle has other main voltage than +12 V. This minimizes the risk of
disturbances from or to the telephone as well as guarantees loss–free
power distribution.
The connections to the battery should be carried out with care. Both the
negative and positive leads have 3A fuses, which must always be used. If
a fuse blows, replace it only with the same type and size fuse.
The power cables should be routed so that possible sources of
disturbances are avoided. Also ABS–sensors and like should be avoided
as far as possible.

If the vehicle has +24 V electrical system (trucks, all–terrain vehicles ,
etc.), an external voltage reducer must be used. Since the properties of
the reducer are critical, it is recommended to use a reducer supplied by
the manufacturer. This reducer has good protections against transients
produced by vehicles electrical system and it is also capable of
maintaining stabile output during rapid changes in load current.
Figure 2. Reducer
Some vehicles have a main switch (e.g. gas trucks), which separates the
vehicles chassis from the negative lead of the battery. Do under no
circumstances pass this switch, i.e. the grounding of the reducer must be
taken from the body of the vehicle, NOT directly from the battery.
WARNING : DO NOT INSTALL REDUCER
– To engine compartment
– Where there isn’t adequate amount of air for cooling (under the
carpet, etc.)
– Where there is risk of moisture (condensed water, etc.)
Car Radio Muting (XCRM)
The phone 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 based on 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. The maximum load that this line can handle is 250 mA.
Note that an auxiliary relay or muting unit must be used when the car
radio doesn’t have a mute feature available.

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 (SR59), which mutes the
radio by connecting load resistors to the speaker lines of the car radio.
Four loudspeakers can be muted and the maximum permitted power is 20
watts per channel. The muting unit can also be used as a relay to cut the
main supply feed of the car radio.
Ignition Sense (IGNS)
The ignition sense feature prevents the transceiver from draining the car
battery by executing an auto power off 3 minutes after the ignition key has
been turned off (unless the Auto Power Off feature is activated).
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 200 mA fuse to a
12/24 volts potential that is controlled by the ignition key. Do not connect it
directly to the high voltage sections of the ignition circuit. If the feature is
not used, just leave the wire unconnected, and protect the end of the
cable with insulating tape.
Power Antenna Control (ANTC)
The orange wire of the system cable (ANTC) 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 disappears. The
maximum output current is 200 mA, therefore for example motorized
antenna must be controlled via a relay, see picture below.

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 Guide’ supplied with the phone.
