Mounting Plate and Swivel (MKE­1 and HHS­1)
The mounting plate MKE­1 and swivel mount HHS­1 mounting brackets are interchangeable. Either one can be used to mount both the MCH­8 or the HFJ­3. The MKE­1 is a fixed position mount and HHS­1 is a swivel mount which allows for adjustable mounting angles.

Mobile Holder (MBH­6)
The easiest way to attach the phone to the car is to use "Light Car Kit" installation. The mobile holder MBH­6 is attached the car by using mounting plate MKE­1 or swivel mount HHS­1.

Compact HF Holder (PHF­1)
Compact HF holder (PHF­1) provides and controls the supply voltage and charge current for the handportable. In addition, it controls the audio paths to handsfree equipment, and provides external antenna connection (mini­UHF).

Cigarette Lighter Cable (LCP­2)
The cigarette lighter cable LCP­2 connects to the compact HF holder (PHF­1) via the 5.5 mm d.c. plug. The other connector in the cable (LCP­2) is plugged to the standard cigarette lighter jack of the vehicle. Supply voltage may vary between 10.8 and 15.6 volts. WARNING! ­ MAXIMUM SUPPLY VOLTAGE IS 15.6 VOLTS, MINUS (­) IN THE CHASSIS OF THE

Holder Unit (MCH­8)
The holder unit MCH­8 is used for attaching the phone to the vehicle. It provides connections to external antenna and junction box HFJ­3. Holder unit will be attached in the vehicle by using mounting plate or swivel mount.

Junction Box (HFJ­3)
Handsfree junction box HFJ­3 provides connections between different functional parts of the car installation, supply feed, handset, holder unit and auxiliary connections. It is attached to the vehicle with mounting plate MKE­1, or swivel HHS­1. Supply feed is coming directly from vehicle battery via power cable PCH­4. Junction box provides supply feed for handset and handheld phone. It also includes charger for charging the battery of the phone. Optional handset HSU­1 is connected to the 8 pin modular female connector HANDSET/ACCESSORY located in the edge of the junction box. If the junction box is installed far away from the handset or holder unit, extension cable SCE­4 should be used. The cable from holder unit is connected to the other 8 pin female connector HOLDER next to handset connector. 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 (HFM­4 and HFS­6)
The safest and easiest way to have call while driving is use the handsfree option. The system consist of two components, the microphone HFM­4 and loudspeaker HFS­6. The handsfree microphone can usually be installed on the drivers sunvisor or A­pillar. 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 HFJ­3 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 HFJ­3 SPEAKER jack.

Power Cable (PCH­4)
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 grimp­connectors, 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"

Handset (HSU­1)
An optional handset offers more privacy during the call. The holder is attached with mounting plate MKE­1 or swivel HHS­1.

Modular 8 Pin Extension Cable (SCE­4)
This cable provides an extension between the HFJ­3 and MCH­4.

Mobile Holder (MBH­6) and Compact HF Holder (PHF­1) together
The holder unit MBH­6 offers firm attachment. It is usually attached to Compact HF Holder PHF­1 with the Cradle Adapter Kit (MKE­4N), which includes the cradle adapter, 4 screws and 4 nuts. To attach the MBH­6 to the PHF­1 first you have to remove the lower cover of PHF­1 by detaching the four crossheaded screws visible underneath the PHF­1 (Figures 1, 2). Insert the four provided nuts into the corresponding slots in the cradle adapter MKE­4N, and slide the cradle adapter into its place underneath the MBH­6 (Figure 3). Do not use mounting plate MKE­1 in place of cradle adapter MKE­4N. Mount MBH­6 to its slot in the front part of PHF­1, and finally attach it by using the provided screws (Figures 4, 5). It is also possible to use the MBH­6 as a separate mobile holder, it is then attached to the vehicle with MKE­1 or HHS­1.

Antenna
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 kit. 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 ground 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 rust­proofing 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 glass­mounted 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 anti­skid 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 non­radiating 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 TNC­female type antenna connector for reasons of reliability and attenuation.

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 loss­free 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 ABS­sensors and like should be avoided as far as possible. If the vehicle has + 24 V electrical system (trucks, all­terrain 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.

Some vehicles have a main switch (e.g. gas trucks), which separates the vehicles chassis from the negative lead of the battery. Under no circumstances do not pass this switch, i.e. the grounding of the reducer must be taken from the body of the vehicle, NOT directly from the battery. 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 (condensated 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, it is connected in series with the car radio main supply. Bosch P/N 0­332­204­150 12 V, 30 A. SPDT A 200 mA fuse should be used to 87A CAR protect the XCRM output in event of RADIO 12 V d.c. a short circuit. Some radios have 30 separate supplies for amplifiers and Supply for 87 car radio motors, and another for memory backup purposes. Very often these 12 V d.c. 86 85 radios also have a secret code system, Fuse 200 mA which activates itself if a break in the To XCRM line (not supplied) (PCH­4/yellow) 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 positioning 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 easily distracted 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.) or observing the traffic. 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 although that the housing doesn't like moisture or mechanical pressure. Handsfree microphone can usually be installed in the sunvisor of the driver, or in the A­pillar. 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 gets under any mechanical stress e.g. under seats or against sharp edges of car chassis. The holder unit should be always connected to the antenna via a non­radiating cable (e.g. coax). The antenna shall be mounted in a position such that no part of the human body will normally rest close to any part of the antenna unless there is an intervening metallic screen, for example, the metallic roof. All installations should take into account any special requirements of the customer. However, should the customer require an installation that is illegal on unsafe these facts must be pointed on the customer and a policy of non­compliance adopted.
