SAFETY NOTICES
This radar equipment must be installed and operated in accordance with the
instructions contained in this manual. Failure to do so can result in personal
injury and/or navigational inaccuracies. In particular:
1. HIGH VOLTAGE. The scanner unit contains high voltages. Adjustments
require specialised service procedures and tools only available to qualified
service technicians – there are no user serviceable parts or adjustments. The
operator should never remove the scanner unit cover or attempt to service the
equipment.
2. ELECTROMAGNETIC ENERGY. The radar scanner transmits
electromagnetic energy. It is important that the radar is turned off whenever
personnel are required to come close to the scanner to perform work on the
scanner assembly or associated equipment.
It is recommended that the radar scanner is mounted out of range of personnel
(above head height).
Do not look directly at the antenna at close range as your eyes are the most
sensitive part of the body to electromagnetic energy.
When properly installed and operated, the use of this radar will conform to the
requirements of ANSI/IEEE C95.1-1992 Standard for Safety Levels with
Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 Hz
to 300 GHz and NRPB, Board Statement on Restrictions on Human Exposure
to Static and Time Varying Electromagnetic Fields and Radiation, Doc NRPB,
No. 5 (1993).
3. NAVIGATION AID. This radar unit is only an aid to navigation. Its
accuracy can be affected by many factors, including equipment failure or
defects, environmental conditions, and improper handling or use. It is the user’s
responsibility to exercise common prudence and navigational judgements.

EMC installation guidelines
All Raytheon equipment and accessories are designed to the best industry
standards for use in the leisure marine environment.
Their design and manufacture conforms to the appropriate Electromagnetic
Compatibility (EMC) standards, but correct installation configuration is
essential to maintain EMC performance and CE compliance. Although every
effort has been taken to ensure that they will perform under all conditions, it is
important to understand what factors could affect the operation of the product.
To avoid the risk of operating problems, all Raytheon equipment, and cables
connected to it, should be installed as follows:
• Ensuring you follow the installation instructions in Chapter 2, particularly
with reference to earthing details.
• With at least 1 m (3 ft) from any equipment transmitting or cables carrying
radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios,
the distance should be increased to 2 m (7 ft).
• Avoiding the beam from another radar scanner. A radar beam can normally
be assumed to spread 20 degrees above and below the radiating element.
• The equipment should be supplied from a different battery than the one used
for engine start. Voltage drops below 10.7 V in the power supply to our
products can cause the equipment to reset. This will not damage the
equipment, but will cause the loss of some information and can change the
mode of operation.
• Genuine Raytheon cables must be used at all times. Cutting and rejoining
these cables can degrade EMC performance and must therefore be avoided
unless specifically detailed in this handbook.
• If a suppression ferrite is attached to a cable, this ferrite must not be removed.
If the ferrite has 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.
154_2c1.p65
13/05/99, 13:17
Chapter 1: Overview
If your Raytheon equipment is going 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.
1.2 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.

Chapter 1: Overview
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 minimise 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 ship’s 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:
- Safety -the scanner should above head height of personnel. 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.
• Access: The scanner unit site should be easily accessible to allow
maintenance to be carried out safely.
• Magnetic compass: Mount the scannner 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.
• 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
154_2c1.p65

Pathfinder Radar Scanners
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 minimised 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:
• 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 30 kg.
• 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 (2½ in). When using
the mast mount kit, appropriate hardware should be used for the style and
structure of the mast aboard the vessel. 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.
154_2c1.p65
13/05/99, 13:17
Chapter 1: Overview
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.
Setting the radiation plane
The scanner unit should be mounted so that the array rotates parallel to the
waterline. The radar beam is approximately 25° wide in the vertical direction,
providing good target detection during the vessel’s pitching and rolling.
Planing hull vessels, and some displacement hull vessels, adopt a higher bow
angle when the vessel is at its cruising speed. In many cases this substantially
alters and raises the radar’s main radiation plane, and can cause poor detection
of nearby targets. It may be helpful to lower the radar beam back towards the
parallel, by shimming the rear of the radar, so that the beam points slightly
downwards with respect to the waterline when the vessel is at rest.
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 runs
You need to consider the following before installing the system cables:
– You need to fit the inter-unit cable and the power cable.
– 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)
You need to run the following cables:
CAUTION
Do not pull the cable through bulkheads using a cord attached to the
connector. This could damage the connections.
• Inter-unit cable . A vinyl-covered and shielded cable is supplied with the
radome scanner unit. The cable has a connector plug at one end for
connecting to the display unit or extension cable; the other end of the radome
scanner cable is fitted with an 8-way plug and power cores (covered by a
clear protective sleeve) for connecting to the scanner.
For open array scanners, various length cables are available. These 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)
• Power cable, the scanner receives power via the display unit. The power
cable is supplied with the display unit. However, cable details are provided in
this section.
Rejoining Cables
You should avoid cutting and re-joining cables. If this is necessary you must:
• Fit a ferrite on each side of the join. The specific ferrite to use depends on the
cable type - contact Raytheom Marine for details.
• Take care not to damage any of the wires. Make sure that all the wires and, in
particular, the screen are reconnected correctly.
If you are mounting the scanner on the mast of a sailboat, and will need to
unstep the mast, you should install a suitable junction box inside the boat.
On a radome scanner, the junction box should provide an 11- or 13-way
terminal strip, depending on the number of power cores in your cable, with a
10 A rating. Also, you should keep the length of the un-screened coaxial cores
to less than 30 mm to maintain EMC conformance.
154_2c1.p65
10
13/05/99, 13:17
Chapter 1: Overview
11
On an open array scanner, the junction box should provide a 13-way terminal
strip with a 20 A rating for power cores. It is essential that all 4 power cores are
connected and that the connection is of very low resistance as considerable
power passes through this connection. Also, you should keep the length of the
un-screened coaxial cores to less than 30 mm to maintain EMC conformance.
Inter-unit cable
The inter-unit cable entrance is at the rear of the scanner unit. If the unit is
mounted on a hollow mast the cable may be run inside the mast and then fed
through the radar’s cable entrance. Make sure that the cable does not chafe
where it enters and exits the mast.
Note: Route the cable from the display up to the scanner, since this will require
the smallest clearance hole.
CAUTION
The display connector on the inter-unit cable is a moulded plug that
cannot be replaced. DO NOT remove this moulded plug.
The inter-unit cable, for connecting the scanner to the display unit, depends on
your scanner package as follows:

The minimum bends permitted are:
Minimum bend, light cable
Minimum bend, heavy cable
60 mm (~2.5 in) radius
82 mm (~3.75 in) radius
Radome scanner cable
The length of the supplied cable should be sufficient to complete the cable run
required on most small vessels. For longer runs, additional or replacement
cables are available, which have 4 power cores to minimise voltage drops over
the longer cable run: these optional cables include 5 m and 10 m extension
cables, and a 25 m replacement cable.
The maximum inter-unit cable length is limited by the minimum supply
voltage, the scanner type (18" radome or 24" radome), and the cable type (2 or 4

connected through.
Note: For vessels with 24 V power systems, any combination of inter-unit
cables can be used.
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

Power cable - radome scanners
The radome radar systems are intended for use on ships’ DC power systems
operating in the 10.7 to 32 V DC range (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 ship’s DC power to the radar scanner via the display unit. Refer
to the HSB Series Display Owner’s 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.

Pathfinder Radar Scanners
For vessels with 12 V power systems, longer power cable runs may require
larger wire gauges to minimise any voltage drop in the cable. The scanner type
and the length and type of the inter-unit cable (see tables) also affect the wire
gauge required for the extension power cable. In order to determine the correct
supply cable size if the power cable must be extended, estimate the length of
cable between the ship’s main power source and the connector block, and then
select the wire size indicated by the distance and inter-unit cable in the
appropriate table following.
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
inter-unit 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.

Power cable - open array scanners
The 48" 4 kW open array scanner is intended for use on ships’ DC power
systems operating in the 10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V
systems). Open array scanners draw considerable power from the vessels
power source, especially in high wind speeds. It is essential for reliable
operation that the unit is supplied with a low resistance power cable system,
especially when operated from a 12 V power system.
CAUTION
Do not use the 48" Open Array Scanner with an SL70 or Autohelm 7”
LCD display unit. Failure to observe this may result in permanent damage
to the display unit.
12 V systems
Extensions to the supplied power cable must be kept to a minimum and the
power should be fed directly from the output of the battery isolator switch via
its own dedicated cable system. It is recommended that no additional power
switch is included in this power cable.
CAUTION
The display unit does not include a fuse for scanner power, so an in-line
fuse or circuit breaker rated at 20 A MUST be included in the power cable.
All power connections must be of high quality to minimise their resistance and
to remove the risk of accidental shorts. Recommended maximum power cable
extensions are given in the table below. These figures relate to the total cable
extension, from the end of the supplied 1.5 m power cable to the system battery
terminals. Do not exceed these lengths as unreliable operation may result.

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.

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.
Note: If you are using a Raytheon mast mount bracket, the surface is preprepared.
Note: If you are mounting the scanner on a flat surface, you may find it
easier to fit the drain tube, as described in the following section, before
securing the scanner.
2. Position the scanner on the mounting surface, ensuring that the cable inlet is
pointing aft.
3. Locate the bolts and washers supplied with the scanner, grease the bolts,
and secure the scanner to the mounting surface as shown in the following
diagram.

Connecting the radome scanner inter-unit cable
CAUTION:
Before wiring the scanner unit, make sure that the inter-unit cable is not
connected and power is not applied to the display unit.
When you have run the inter-unit cable to the scanner location, connect the
cable as follows:
1. Loosen the 4 (18") or 7 (24") screws securing the scanner cover. These
screws are captive and should remain assembled to the lower flange
assembly. Press the radome inwards to release the top. This breaks the seal
and makes removal easier.
2. To avoid losing the scanner cover, tie the cord, attached to the inside of the
base of the scanner, to the eye provided in the cover.
3. If you have a 24" scanner, unscrew and remove the inner cover:

7. Cut and remove the protective sleeve to expose the 8-way plug (4) and
power cores (6).
8. If the scanner is connected to an HSB Series Pathfinder Radar display, fit
the ferrite clamp (11), supplied loose with the display unit, as follows:
CAUTION
If any wires are damaged when the clamp is fitted, the scanner unit will
not function correctly.
- the ferrite clamp is supplied open. If the clamp has been closed, insert a
small, flat-blade screwdriver into the slots at the end of the clamp
opposite the hinge and twist gently.
- Position one-half of the clamp around the eight cores of the inter-unit
cable between the 8-way plug (4) and the cable clamp, as close to the 8way plug as possible. (It may be necessary to fit the clamp over the
154_2c2.p65

cable tie closest to the 8-way plug – this will not affect the ferrite
clamp’s function).
Note: on the 24" scanner, the clamp must be contained inside the inner
cover.
- With the clamp positioned correctly, close the clamp ensuring none of
the cores are trapped by the hinge, latch or the ferrite itself.
9. Connect the 8-way plug (4) to the connector (5). The correct fitting is with
the small arrow marked on the body of the plug facing upwards and to the
left hand side. The grey wire will then be at the left hand side and the white
wire will be at the right hand side.
10. Connect the red and black power cores (6).
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 (7) are operated using a screwdriver (8), as shown in
the inset diagram on the previous page.
CAUTION:
Do not earth the cable screen to the scanner. The radar system is earthed
via the display unit.
11. Secure the nut (1) on the watertight gland, making sure that it grips the
cable’s outer sheath.
12. Secure the cable with the cable clamp (9), using the two screws (10)
provided. The clamp can be installed either way up, depending on the
thickness of the cable: use the position that matches the profile of the cable.
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 irrepairable damage.
13. Tighten the securing nut (1) again to ensure a waterproof seal.
14. If you have a 4D scanner, replace the inner cover over the connectors.
15. 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.
16. 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 Raytheon Marine dealer.
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 protective cap fitted over the open array mounting
shaft. This cap must be left in place until the open array is fitted to the
pedestal in order to protect the co-axial pin which protrudes from the
pedestal.
WARNING
The open array scanner weighs 30 kg. 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 esure 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.
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.
4. Grease the studs. Using two nuts locked together on the stud, screw each
studs into the pedestal until they bottom out. Remove these two nuts and
secure the studs with the fixings as shown in the following illustration.
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.

2.3 System connections
DC power connection
Power is supplied to the scanner via the display unit; the power cable is supplied
with the display unit, refer to your display unit Owner’s Handbook for details
on connecting power. However, you should be aware of the following.
The DC system should be either:
• Negative grounded, with the negative battery terminal connected to the
ship’s ground.
• Floating, with neither battery terminal connected to the ship’s ground.
CAUTION:
This radar is not intended for use on “positive” ground vessels.
The power cable Earth screen connections must be connected to the ship’s
ground.
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/
NMEA Input cable to the nearest ground point of the ship’s RF ground system.
Refer to your display unit Owner’s Handbook for details.
Note: Use only this ground connection.
Radome systems
The Radome radar system is intended for use on ships’ DC power systems
operating in the 10.7 to 32 V dc range (12 V and 24 V systems, not 32 V
systems). The connections should be made at a DC power distribution panel,
through an isolation switch or circuit breaker that is fused or trips at not greater
than 10 A. Check that all connection terminals are clean.
CAUTION:
If you do not have a breaker in your power circuit, you must fit an in-line
6.3 A quick-blow fuse to the positive (red) lead of the power cable.
Open array systems
The 5S 48" open array radar system is intended for use on ships’ DC power
systems operating in the 10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V
systems). 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, rated at 20 A for 12 V systems or 10 A for 24 V and
32 V systems, MUST be included in the positive supply lead (red) of the
power cable.

Pathfinder Radar Scanners
The open arrray scanner has a power switch fitted to the pedestal. This switch
can normally be left ON. However, if the scanner is being serviced or if any
personnel are in the vicinity of the open array, the switch should be set to OFF.
Scanner connection
The inter-unit cable is connected to the scanner as described in Sections 2.1 and
2.2. If you are using an inter-unit extension cable, connect this to the display
unit, and connect the supplied cable to the extension cable. The scanner
connector pins are shown in the following diagram, together with the
connections and core colours.
CAUTION
The display connector on the inter-unit cable is a moulded plug that
cannot be replaced. DO NOT remove this moulded plug.

Chapter 3:
System Tests and Post Installation Alignment
Once you have installed your radar scanner and display unit, and made all the
connections, you need to check your installation. You can then set up the radar
system, align the scanner and check the display timing.
Set up, alignment and timing checks are performed from the radar system
display unit. The procedures are outlined below; full details are provided in the
display unit Owner’s Handbook. You should read the Pathfinder radar display
unit Owner’s Handbook and familiarise yourself with the operation of the
radar.
System check
Before performing the functional test, check the following:
• All securing bolts are fully tightened and mechanical locking arrangements
as specified are in place
• All connections have been made
• All connecting wires are secured and protected as necessary
Note: If you are the boat owner and have performed the installation yourself,
ask your authorised installation dealer to check the installation before going to
sea.
Set up, alignment and timing checks
Switch on and initial set up
On the 48" open array scanner, ensure the power switch on the pedestal is set to
ON.
To switch on the display unit, press and hold the POWER key until the unit
beeps. The magnetron warm-up sequence should start, after which the unit
should enter Standby mode.
If necessary, adjust the lighting and contrast.
If required, change the default language settings.
Checking transmission
WARNING:
The radar scanner transmits electromagnetic energy. Ensure that the
scanner has been installed according to the recommendations given in
Chapter 1, and that all personnel are clear of the scanner, before switching
to transmit mode.

Pathfinder Radar Scanners
Run through the radar operations described in the display unit Owner’s
Handbook and check that all the expected data is displayed.
Bearing alignment
When the system is correctly installed, you must check the bearing alignment to
ensure that targets appear at their correct bearing relative to the ship’s bow, and
adjust the alignment if necessary.
Display timing adjustment
The display timing can be affected by the length of the cable used to connect the
scanner to the display unit. This in turn affects the short range accuracy shown
on the display.
If you have extended your inter-unit cable, you will need to check the display
timing before using the system for navigation.
