3 The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V (20 V for 10 kW open array scanners) in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. Raymarine specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual. If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. Section 2.1, Radome scanner includes instructions on fitting a ferrite. The following illustration shows a typical range of suppression ferrites fitted to Raymarine equipment.

Connections to Other Equipment
If your Raymarine equipment is to be connected to other equipment using a cable not supplied by Raymarine, a suppression ferrite MUST always be fitted to the cable close to the Raymarine unit.
1.2 Unpacking and inspecting the components
Unpack your system carefully, to prevent damage to the equipment. It is good practice to save the carton and packing for future use, in case you need to return the unit for service. Check that you have all the correct system components. These depend on your system package, as detailed in the following tables.

1.3 Selecting the scanner unit site
This section provides information that affects the possible locations of the scanner, and its position relative to the display unit and to the power supply. The dimensions of the each scanner unit are shown in the following diagrams. Selecting the best location for the scanner unit requires careful consideration of the following points, to ensure reliable and trouble free operation:
Note: In order to minimize potential interference to other systems on board ship (EMC), it is advisable to mount the scanner on a part of the boat that is insulated from the ships battery negative. If you cannot do this, and encounter problems, you can fit insulating bushes between the scanner and its mounting bracket.
Height: The scanner unit should normally be mounted as high as practical above the waterline, for three reasons: For safety reasons the scanner should be out of range of personnel, preferably above head height. This avoids mechanical danger and electromagnetic contact, particularly with the eyes. Radar operates at the line-of-sight, so a high mounting position gives better long range performance. Surrounding large objects, in the same horizontal plane, can interfere with the radar signal and cause blind areas or shadow sectors and false targets on the radar screen (see below). However, do not mount the scanner so high that it is affected by the pitching and rolling of the vessel. In addition, you may need to lower the scanner to avoid creating a shadow sector underneath the scanners beam.

Pathfinder Radar Scanners Access: The scanner unit site should be easily accessible to allow maintenance to be carried out safely. Magnetic compass: Mount the scanner unit at least 1 m away from a magnetic compass. Cable run: The maximum length of cable between the display unit and the scanner unit should not normally exceed 20 m (60 ft) for radome scanners, or 15 m (45 ft) for open array scanners. If you need to use a longer cable power cable lengths must be considered, refer to Section 1.4 Cable Runs to determine appropriate lengths. Shadow sectors and false echoes: Mount the scanner away from large structures or equipment, such as the fly bridge, large engine stacks, searchlights, horns, or masts. It is particularly important to avoid shadow sectors near the bow. Raising or even lowering the scanner may help to reduce these effects. In shadow areas beyond the obstruction there will be a reduction of the beam intensity, although not necessarily a complete cut-off; there will be a blind sector if the subtended angle is more than a few degrees. In some shadow sectors the beam intensity may not be sufficient to obtain an echo from a very small object, even at close range, despite the fact that a large vessel can be detected at a much greater range. For this reason the angular width and relative bearing of any shadow sector must be determined at installation. Sometimes shadowing can be seen by increasing the radar gain until noise is present. Dark sectors indicate possible shadowed areas. This information should be posted near the display unit and operators must be alert for targets in these blind sectors. It should also be noted that wet sails create shadow areas and thus sail boat operators should be aware that radar performance may reduce in rain. If you mount the scanner on a mast, echoes from the mast may appear on the radar display. These can be minimized by placing absorbing material, such as a block of wood, between the scanner and mast. Platform rigidity/stability: The scanner platform should not twist (causing bearing errors) or be subject to excessive vibration. Heat/fumes: Mount the scanner away from the top of exhaust stacks, since the scanner and cables can be damaged by excessive heat and the corrosive effects of exhaust gases. For open array scanners you should also consider the following points:

Wedge or washers

The shims may be made from aluminium plate wedges, simple flat washers, or an angled wooden block. For thick shims, you may need longer securing bolts than the M8x40 bolts supplied with the radome scanner, or the M10 studding supplied with the open array scanners.

1.4 Cable Requirements

This section provides details on selecting the appropriate cables for your system. Permissible cable lengths depend on the scanner type and the boats power system. Information on inter-unit and power cables is provided for both radome and open array scanners in the following sections. You need to consider the following before installing the cables: You need to connect the scanner to the display unit and to power. The cable required depends on the display unit and the scanner type as described below. All cables should be adequately clamped and protected from physical damage and exposure to heat - avoid running cables through bilges or doorways, or close to moving or hot objects. Acute bends must be avoided. Where a cable passes through an exposed bulkhead or deckhead, a watertight gland or swan neck tube should be used. Avoid cutting and re-joining cables (if necessary, refer to the notes below).

Scanner Cables

The cable used to connect your scanner to the display unit and power depends on the type of scanner and display as follows: A radome scanner connected to a Pathfinder or C-Series display requires an inter-unit cable. The scanner receives power via the display unit, the power cable is supplied with the display unit but cable details are provided in this section. An open array scanner connected to a Pathfinder display requires an inter-unit cable. The scanner receives power via the display unit, the power cable is supplied with the display unit but cable details are provided in this section. An open array scanner cannot be powered from a C-Series Display; it requires a split pedestal cable which combines the inter-unit and power cores. If you are connecting a C-series display to an existing open array scanner unit with a standard inter-unit cable, you can use the adapator cable instead of the split pedestal cable; connect the adaptor between the inter-unit cable and the display. These cables are illustrated in the following diagram. Cable lengths and part numbers are listed in Unpacking and inspecting the components on page 3. CAUTION: The cable for connecting an open array scanner to a C-series display cannot be extended.

Notes: (1) For vessels with 24 V power systems, any combination of inter-unit cables

can be used.

(2) This table applies to systems using the standard 1.5 m power cable. If you
extend the power cable you may need to select different inter-unit cable(s), as discussed in the following section Power Cable.

Power cable

The radome radar systems are intended for use on ships DC power systems operating in the range 10.7 to 32 V DC (that is, 12 V and 24 V systems; not 32 V systems). A 1.5 m (5 ft) power cable is supplied (with the display unit) for connecting the ships DC power to the radar scanner via the display unit. Refer to the Display Unit Owners Handbook for details on connecting this cable. This section provides details for extending the length of the power cable. If a longer power cable run is required, use the supplied power cable to connect to the display unit. Then use a suitable connector block to connect the free end to the extension cable. The supplied power cable has a cross-section of 2.0 mm2.
Note: For vessels with 24 V power systems, the power cable may be extended by up to 20 m using a wire gauge of 1.5 mm2 (AWG 16) or greater, irrespective of the inter-unit cable length.
For vessels with 12 V power systems, longer power cable runs may require larger wire gauges to minimize any voltage drop in the cable. The type of scanner, type of inter-unit cable and cable length also affect the wire gauge required for the extension power cable. To determine the correct supply cable size: 1. Estimate the length of cable between the ships main power source and the connector block. 2. Use the followings tables (one for each scanner size) to determine, for each inter-unit cable combination, the wire size required for that length. For example, you might have a 24" scanner, with 20 m between the scanner and display unit, that you plan to connect by extending the supplied 15 m heavy interunit cable with a 5 m extension cable. In addition, your 12 V power supply might be 10 m from the display unit, requiring an extension of 8.5 m. To determine the wire gauge required for the power cable extension, refer to the table for the 24" scanner, go to the row labelled 15 m Heavy + 5 m ext, and read across until you come to a maximum cable length greater than 8.5 m. This is the 10 m entry, in the column for 4.0 mm2 wire gauge.

Open array scanner cables for Pathfinder displays
The Pathfinder display inter-unit cables have a connector plug at one end for connecting to the display unit or extension cable; the other end is prepared ready to fit to the power and signal connectors (see Section 2.2). Heavy duty cables are available in 15 m and 25 m lengths which should be sufficient to complete the cable run required on most small vessels. For longer runs, 5 m and 10 m extension cables are available, both have 4 power cores to minimize voltage drops over the cable run and incorporate in-line moulded plugs. The maximum inter-unit cable length is limited by the minimum supply voltage and the scanner type. CAUTION: 10 kW scanner systems cannot be used directly with 12 V systems; they require a 12 V to 24 V converter rated to 180 W. Contact your authorized Raymarine dealer or distributor for details. 12 V Systems (4 kW scanners only) For vessels with 12 V power systems, the recommended cable(s) for different run lengths are given in the following table, which assumes a minimum supply voltage of 10.7 V (the lowest voltage likely to be reached by a 12 V battery in normal marine use). Do not use cable combinations that are not included in the table. Table 1-6: Recommended 4 kW Open Array Scanner Inter-Unit Cable(s) for Vessels with 12 V Power Systems

The DC system should be either: Negative grounded, with the negative battery terminal connected to the ships ground. Floating, with neither battery terminal connected to the ships ground. CAUTION: This radar is not intended for use on positive ground vessels. The power cable Earth screen connections must be connected to the ships ground.
Pathfinder Radar Scanners Grounding the radar system It is important that an effective RF ground is connected to the radar system. You must ground the radar by connecting the drain wire (screen) of the power cable to the nearest ground point of the ships RF ground system. Refer to your display unit Owners Handbook for details. If you need to extend the wire, the extension wire should be an 8 mm braid or AWG 10 (6.0 mm2) multi-stranded cable. If your vessel does not have an RF system, connect the drain wire to the negative battery terminal.
Note: Use only this ground connection.
Power Connections The power connection to the radar should be made at either the output of the battery isolator switch, or at a DC power distribution panel. Raymarine recommends that power is fed directly to the radar via its own dedicated cable system and MUST be protected by a thermal circuit breaker or fuse, fitted close to the power connection. Refer to the table below for isolator switch, circuit breaker or fuse value ratings. Check all terminal connections are clean. CAUTION: If you do not have a thermal circuit breaker or fuse in your power circuit, e.g. fitted to the DC distribution panel, you MUST fit an inline breaker or fuse to the positive (red) lead of the power cable.

Chapter 2: Installing the Scanner

2.1 Radome scanner

Securing the radome scanner to the mounting surface
CAUTION: The drain tube must always be used, but may be shortened if necessary 1. Using the paper template supplied with the scanner mounting kit, mark the flat mounting surface with the mounting holes and drain tube hole, and drill the holes as indicated on the template. If it is impractical to drill a hole for the drain tube, then the scanner unit should be mounted on 4 suitable spacers 10 mm high and the drain tube length reduced by 10 mm. It will then be clear of the flat surface and can still perform its function.

27 9. Connect the red +and black - power cores (7). If you have a 10 m or light 15 m inter-unit cable, there is one pair of cores. Connect the red cable lead to one of the terminal sockets marked +, and the black cable lead to one of the sockets marked -. If you have a heavy 15 m inter-unit cable, there are two pairs of cores. Connect the red cable leads to the terminal sockets marked +, and the black cable leads to the terminal sockets marked -, with one lead in each socket. The terminal clamps (8) are operated using a screwdriver (9), as shown in the inset diagram on the previous page. 10. Secure the nut (1) on the watertight gland (2), making sure that it grips the cables outer sheath. 11. Secure the cable with the top clamp (11), using the two screws (12) provided. Ensure that the clamp goes around the exposed wire braid, and that the wire braid makes contact with the earthing clamp. Tighten the screws until the top clamp deforms just enough to contact the lower earthing clamp (see inset). CAUTION: It is essential that the drain tube is fitted and that the nut on the watertight gland is adequately tightened. If this is not done, water could become trapped in the scanner and cause irreparable damage. 12. Tighten the securing nut (1) again to ensure a waterproof seal. 13. If you have a 4D scanner, replace the inner cover over the connectors. 14. Untie the cord from the scanner cover, and coil it up in the base of the scanner unit so that it cannot foul the rotating antenna. 15. Replace the scanner cover, aligning the mark on the cover with the mark on the scanner base above the cable gland, and tighten the 4 or 7 captive screws. Do not over-tighten these screws.

2.2 Open array scanner

Installation of the open array scanner should only be undertaken by a competent installer. If you have any difficulty with the installation, please contact your local Raymarine dealer or distributor. The open array scanner is supplied in two sections; the pedestal unit and the antenna. The pedestal unit is secured from below the mounting platform. The open array is then secured to the pedestal. Full details for mounting the scanner are given below. CAUTION: The pedestal unit has a cap fitted over the open array mounting shaft to protect the protuding co-axial pin. This cap must be left in place until the open array is fitted. The pedestal base is fitted with a seal: DO NOT grease this seal. WARNING: The open array scanner weighs: 48" scanner - 30 kg (66.2 lb); 72" scanner - 33.4 kg (73.7 lb). For safety reasons it is recommended that the unit is not lifted by one person. The unit is fitted with lifting eyes (maximum SWL 40 kg) to facilitate the use of standard lifting accessories, e.g. rope, chain or strop. The safe working load (SWL) of the lifting accessories should be 150 kg. Suitable lifting equipment could include a crane, hoist, or an appropriate rigid, overhead structure. Alternatively, the unit is suitable for a two person lift. Care must be taken to ensure that each person is standing on a stable surface, and that the pedestal is held carefully to ensure it cannot slip. The T-bar beneath the open array antenna can be used to aid lifting. You should never lift the scanner by holding onto the open array antenna.

3.2 Maintenance

Warnings
The display unit and scanner unit contain high voltage. Adjustments require specialized service procedures and tools only available to qualified service technicians - there are no user serviceable parts or adjustments and the operator should not attempt to service the equipment. The operator should not
remove the rear cover of the display or any internal covers in the scanner.
Always turn the radar system off before carrying out any routine maintenance on the scanner or nearby equipment. Switch off the display unit before removing the power cord.

Routine Checks

The radar scanners are sealed units. Maintenance procedures are therefore limited to the following periodical checks: Examine the cables for signs of damage, such as chafing, cuts or nicks. Check that the cable connectors are firmly attached. Make sure the scanner and pedestal are still attached securely to the mounting. Once a year, remove, grease and re-attach the mounting bolts securing the scanner and pedestal.

Servicing and Safety

Raymarine equipment should be serviced only by authorized Raymarine service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raymarine product. Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment. When powered, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimize these effects and enable you to get the best possible performance from your Raymarine equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC).
Pathfinder Radar Scanners Always report any EMC-related problem to your nearest Raymarine dealer. We use such information to improve our quality standards. In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.

3 In the case of SSB radios, the distance should be increased to 2 m (7 ft). More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally be assumed to spread 20 degrees above and below the radiating element. The equipment is supplied from a separate battery from that used for engine start. Voltage drops below 10 V (20 V for 10 kW open array scanners) in the power supply to our products, and starter motor transients, can cause the equipment to reset. This will not damage the equipment, but may cause the loss of some information and may change the operating mode. Raytheon specified cables are used at all times. Cutting and rejoining these cables can compromise EMC performance and so must be avoided unless doing so is detailed in the installation manual. If a suppression ferrite is attached to a cable, this ferrite should not be removed. If the ferrite needs to be removed during installation it must be reassembled in the same position. Section 2.1 Installing the Radome Scanner includes instructions on fitting a ferrite.
The following illustration shows a typical range of suppression ferrites fitted to Raytheon equipment.

D3548-2

Connections to Other Equipment
If your Raytheon equipment is to be connected to other equipment using a cable not supplied by Raytheon, a suppression ferrite MUST always be fitted to the cable close to the Raytheon unit.

1.3 Selecting the scanner unit site
This section provides information that affects the possible locations of the scanner, and its position relative to the display unit and to the power supply. The dimensions of the each scanner unit are shown in the following diagrams. Selecting the best location for the scanner unit requires careful consideration of the following points, to ensure reliable and trouble free operation: Note: In order to minimize potential interference to other systems on board ship (EMC), it is advisable to mount the scanner on a part of the boat that is insulated from the ships battery negative. If you cannot do this, and encounter problems, you can fit insulating bushes between the scanner and its mounting bracket. Height: The scanner unit should normally be mounted as high as practical above the waterline, for three reasons: For safety reasons the scanner should be out of range of personnel, preferably above head height. This avoids mechanical danger and electromagnetic contact, particularly with the eyes. Radar operates at the line-of-sight, so a high mounting position gives better long range performance. Surrounding large objects, in the same horizontal plane, can interfere with the radar signal and cause blind areas or shadow sectors and false targets on the radar screen (see below). However, do not mount the scanner so high that it is affected by the pitching and rolling of the vessel. In addition, you may need to lower the scanner to avoid creating a shadow sector underneath the scanners beam.

Chapter 1: Overview For open array scanners you should also consider the following points:
Mounting Platform: The platform must be mechanically secure and capable of supporting the mass and inertia of the open array scanner. The complete unit weighs: 48" scanner - 30 kg (66.2 lb); 72" scanner - 33.4 kg (73.7 lb). The site must be clear of ropes and moving rigging. Sufficient clearance must be allowed to fully open the open array pedestal for maintenance.
Mounting surface: sailboats
The scanner unit can be installed on a mast platform, an arch, or a bridge structure. Make sure that the platform surface is flat and the scanner unit drain hole (radome scanners) is not obstructed. Raytheon recommends that radome scanner units are best suited for sailboat operation as open array systems are more difficult to protect from ropes and sails. For sailboat installations, Raytheon offers a universal mast mount kit for each radome scanner type. This optional mount is used to fit a radome scanner to a flat surface on a mast with a minimum diameter of 60 mm (2 in). When using the mast mount kit, appropriate hardware should be used for the style and structure of the mast aboard the vessel. Typically, the scanner will be mounted near the first set of mast spreaders. If there is any doubt concerning the appropriate type of hardware, consult your boat dealer or representative for their recommendations. Depending on the type of sailboat, a radar scanner guard should be installed if the sails could touch the scanner or platform. Without a proper radar guard the mounting platform and the radar scanner could be severely damaged.
Mounting surface: power boats
On many small vessels the scanner unit can be installed on a mast platform, an arch, or a bridge structure, but take care to follow the scanner site guidelines, particularly regarding height. If necessary, construct a radar mounting platform to obtain a sufficiently high mounting position. Make sure that the platform surface is flat and the scanner unit drain hole (radome scanners) is not obstructed. Ensure the platform is strong enough to support the maximum shock loads likely to occur.

Open array scanner cables
Heavy duty cables are available in 15 m and 25 m lengths which should be sufficient to complete the cable run required on most small vessels. For longer runs, 5 m and 10 m extension cables are available, both have 4 power cores to minimize voltage drops over the cable run and incorporate in-line moulded plugs. The maximum inter-unit cable length is limited by the minimum supply voltage and the scanner type. CAUTION: 10 kW scanner systems cannot be used directly with 12 V systems; they require a 12 V to 24 V converter rated to 180 W. Contact your authorized Raytheon dealer or distributor for details. 12 V Systems (4 kW scanners only) For vessels with 12 V power systems, the recommended cable(s) for different run lengths are given in the following table, which assumes a minimum supply voltage of 10.7 V (the lowest voltage likely to be reached by a 12 V battery in normal marine use). Do not use cable combinations that are not included in the table. Table 1-7: Recommended 4 kW Open Array Scanner Inter-Unit Cable(s) for Vessels with 12 V Power Systems

Note: If the required extension results in unacceptably large diameter cables, use two or more smaller gauge wires to achieve the required copper wire cross-section. For example, using two pairs of 2 mm2 is equivalent to using two single 4.0 mm2 cables. 24 V and 32 V systems These systems are less sensitive than 12 V systems to voltage loss in the power cables. However, it is still necessary to use adequate cables to prevent excessive power loss. The table below gives the recommended wire gauge for different power cable extension lengths. Raytheon recommends that power is fed directly from the output of the battery isolator switch via its own dedicated cable system. CAUTION: The display unit does not include a fuse for scanner power, so an in-line fuse or circuit breaker MUST be included in the power cable. Note: If the required extension results in unacceptably large diameter cables, use two or more smaller gauge wires to achieve the required copper wire cross-section. For example, using two pairs of 2 mm2 is equivalent to using two single 4.0 mm2 cables.

2.2 Open array scanner

Installation of the open array scanner should only be undertaken by a competent installer. If you have any difficulty with the installation, please contact your local Raytheon Marine dealer or distributor. The open array scanner is supplied in two sections; the pedestal unit and the antenna. The pedestal unit is secured from below the mounting platform. The open array is then secured to the pedestal. Full details for mounting the scanner are given below. CAUTION: The pedestal unit has a cap fitted over the open array mounting shaft to protect the protuding co-axial pin. This cap must be left in place until the open array is fitted. The pedestal base is fitted with a gasket: DO NOT grease this gasket.

WARNING:

The open array scanner weighs: 48" scanner - 30 kg (66.2 lb); 72" scanner - 33.4 kg (73.7 lb). For safety reasons it is recommended that the unit is not lifted by one person. The unit is fitted with lifting eyes (maximum SWL 40 kg) to facilitate the use of standard lifting accessories, e.g. rope, chain or strop. The safe working load (SWL) of the lifting accessories should be 150 kg. Suitable lifting equipment could include a crane, hoist, or an appropriate rigid, overhead structure. Alternatively, the unit is suitable for a two person lift. Care should be taken to ensure that each person is standing on a stable surface, and that the pedestal is held carefully to ensure it cannot slip. The T-bar beneath the open array antenna can be used to aid lifting. You should never lift the scanner by holding onto the open array antenna.
154_4.book Page 28 Wednesday, October 25, 2000 3:02 PM
Securing the pedestal to the mounting platform
1. Using the paper template supplied with the scanner mounting kit, mark the flat mounting surface with the holes and drill as indicated on the template. Refer to Section 1.2 when selecting the scanner unit site. 2. Stick the four self-adhesive bitumen washers over the mounting holes. 3. Ensure the lifting eyes are securely fitted to the top of the pedestal, and the yellow protective cap is in place. CAUTION: To prevent damage to the internal mounting bar, ensure the stud penetration is no more than 32 mm into the pedestal base. We recommend you mark each stud with tape, 32 mm from one end, to act as a gauge. 4. Grease the studs. Using two nuts locked together on the stud, screw each stud into the pedestal to a maximum of 32 mm, or until they bottom out. Remove these two nuts. Note: If the studding supplied is not long enough, use M10 stainless steel, grade A4 studding of a suitable length. Refer to the following illustration for details. 5. Using suitable lifting equipment, raise the pedestal over the mounting surface. Carefully lower into position, taking care that the studs pass through the holes without damaging the threads. Ensure that the cable inlet is pointing aft.

Support the pedestal unit until it has been secured to the mounting platform. It is important that all four sets of nuts and washers are used to secure the pedestal to the mounting platform. 6. Referring to the following illustration, use the four nuts and associated washers supplied to secure the pedestal. Tighten the nuts to 20 Nm (14.7 lb ft); ensure the scanner is tightly fitted. Grease the nuts. If required, cut-off any excess stud.

3.2 Maintenance

Warnings
The display unit and scanner unit contain high voltage. Adjustments require specialised service procedures and tools only available to qualified service technicians - there are no user serviceable parts or adjustments and the operator should not attempt to service the equipment. The operator should not remove the rear cover of the display or any internal covers in the scanner. Always turn the radar system off before carrying out any routine maintenance on the scanner or nearby equipment. Switch off the display unit before removing the power cord.

Routine Checks

The radar scanners are sealed units. Maintenance procedures are therefore limited to the following periodical checks: Examine the cables for signs of damage, such as chafing, cuts or nicks. Check that the cable connectors are firmly attached. Make sure the scanner and pedestal are still attached
securely to the mounting. Once a year, remove, grease and re-attach the mounting bolts securing the scanner and pedestal.

Servicing and Safety

Raytheon equipment should be serviced only by authorised Raytheon service technicians. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any Raytheon product. Some products generate high voltages, so never handle the cables/connectors when power is being supplied to the equipment. When powered, all electrical equipment produces electromagnetic fields. These can cause adjacent pieces of electrical equipment to interact with one another, with a consequent adverse effect on operation. In order to minimise these effects and enable you to get the best possible performance from your Raytheon
154_4.book Page 42 Wednesday, October 25, 2000 3:02 PM
Pathfinder Radar Scanners equipment, guidelines are given in the installation instructions, to enable you to ensure minimum interaction between different items of equipment, i.e. ensure optimum Electromagnetic Compatibility (EMC). Always report any EMC-related problem to your nearest Raytheon dealer. We use such information to improve our quality standards. In some installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to spurious resetting action, or momentarily may result in faulty operation.

3.3 Problem Solving
