Handsfree microphone and loudspeaker have male plugs, which are connected
to their female counterparts in the junction box. The diameters are 2.5 and 3.5
mm respectively. Connectors are marked MIC and SPEAKER.
Handsfree Microphone and Speaker (HFM–4 and HFS–6)
The system consist of two components, the microphone HFM–4 and loudspeaker HFS–6.
The handsfree microphone can usually be installed on the sunvisor or A–pillar.
The main idea is to get the microphone as close to the mouth as possible, and
to attach the microphone to a surface that is mechanically quiet. The microphone connects to the HFJ–3 MIC jack.
The loudspeaker should be mounted at least 3 ft/1 m away from the handsfree
mic to avoid acoustic feedback The loudspeaker connects to the HFJ–3
SPEAKER jack.

Power Cable (PCH–4)
The power cable includes supply wires, ignition sense and car radio muting.
The power cables are connected directly to the vehicles battery via fuses, red
wire to the positive pole (+12 V) and black one to the negative pole (GND), unless vehicle has other main voltage than 12 V. The last 1 m part of the cable is
connected by using standard grimp–connectors, which makes power cable
routing from the battery easier. For additional information see section ”Power
Distribution”
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 must be done by using an auxiliary relay, or a muting unit provided by the manufacturer, see ”Car Radio Muting”.
The blue ignition sense (IGNS) wire is connected to +12 V voltage controlled by
the car ignition key. The ignition sense can utilize voltages up to 24 V, see section ”Ignition Sense”

Booster BSH–4 Installation (BSHK–4)
The booster BSH–4 can be used when the handportable is installed in a vehicle. Booster improves the phone’s ability to receive and send calls.
BSH–4 is connected to the holder unit and junction box HFJ–3 by front mount
cable SCE–8. SCE–8 will be connected to the power cable PCH–4. BSH–4 will
be connected to the holder unit MCH–8 by RF extension cable and booster will
also be connected to the mobile antenna by mobile antenna cable.
BSH–4 is attached in the car by using mounting bracket MBM–3. The booster is
attached to the bracket by sliding the two pivots in the booster chassis to the
respective holes in the bracket, pressing the booster down so that it touches
the supports of the bracket and finally tightening the lock screw.
The booster can be installed to the rear or to the front of the car. If the booster
is installed to the front of the car, it will be connected to the junction box by using front mount cable SCE–8. If booster is installed to the rear of the car, it will
be connected to the junction box by using front mount cable SCE–8 and
SCE–9. SCE–9 is extension cable. RF extension cable XRH–1 is same in both
cases. Note that the the extension cable must always

Note! The car kit is designed to operate with a high quality external
antenna. However, due to many different types of antenna available
an antenna is NOT included as part of this kits. It is the responsibility
of the dealer to advise on the most suitable type for a given
installation.
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 interventing metallic screen, for example, the metallic roof.
• highest place in the car
• proper grund place
• omnidirectional radiation pattern
• minimum risk for disturbances
• user safety
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 to its place. Consult the antennas manuals for determing 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 radio equipment shall be connected to the antenna via a non–radiating cable (eg.
coaxial cable).
Most of the antennas today have adapted the minigrimp connector system
which eliminates the need for special grimping tools and connectors. If however
the purchased antenna has traditional connectors, use only proper connectors
and tools. The mounting bracket uses TNC–female type antenna connector for
reasons of reliability and attennuation.

Power Distribution
The main supply for car kit is obtained from the vehicle battery, the supply voltage may vary between 9 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 4 A 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–sencors 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 to maintain stabile output during rapid changes in
load current.

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. When in standby, the yellow wire’s potential is +12 volts, but during a
call it drops down to 0 volts. 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, it is connected in
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 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 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 left the wire unconnected, and protect the end of
the cable with insulating tape.

Positioning
The best guide for positiong the units is your own experience, skills and common sense. However, some aspects requiring special attention will be discussed here.
The positioning of the holder unit is the most important factor when trying to
achieve the most comfortable usage for the user. The location of the holder unit
should be selected so that the visibility of the phone display is good in every
lighting condition, but not so that the drivers attention gets too easily stolen
from driving itself. The holder unit should be located so that the driver can easily reach the keypad. Under no circumstances should the holder unit obstruct
the driver from operating car controls (i.e. handbrake, etc.).
If handset is used like a phone & a holder unit, the handset’s place should be
located according same rules as holder unit is located. If using handset, the
location of the phone is not so critical. In this case location of the phone is determined by the connecting cables and the the obtainable of the phone.

Junction box can also be installed in hidden location, since usually there is no
need to detach cables in normal operation. Remember allthough that the box
doesn’t like moisture or mechanical pressure.
Handsfree microphone can usually be installed in the sunvisor of the driver, or
in the A–pillar. The main idea is to get the microphone quite close to the drivers
mouth, and also to attach the microphone in surface that doesn’t carry the mechanical vibrations of the car body, since these will increase the background
noise when using handsfree.
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 the the 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.
The system cable routing isn’t usually critical; however it should not be routed
next to electronic ignition systems or ABS braking systems wires or boxes to
prevent interference to important automotive electrical components. Take also
care not to run the cable so that it’s gets under any mechanical stress e.g. under seats or against sharp edges of car chassis.
The customer is paying for the installation and expects to get a very good return for his money. Therefore installers first duty is to discuss all the locations
with him/her. Sometimes the customers may have starnge ideas of the locations. Then it is your job to point out politely why these solutions won’t work.
