SAFETY NOTICES
This radar equipment must be installed and operated in accord-
ance 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. Adjust-
ments require specialised service procedures and tools only avail-
able to qualified service technicians – there are no user
serviceable parts or adjustments. The operator should never
remove the scanner unit internal covers or attempt to service the
equipment.
2. Electromagnetic Energy. The radar scanner transmits electro-
magnetic energy. It is important that the radar is turned off when-
ever 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 Fre-
quency 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 han-
dling or use. It is the user’s responsibility to exercise common
prudence and navigational judgements. This radar unit should not
be relied upon as a substitute for such prudence and judgement.

Display Software Version
For full operation of the open array scanners, the display unit
requires an appropriate software version. For new displays, the
correct software version is normally already installed in the dis-
play unit and is fully compatible with the 2D and 4D radome
scanners.
Early display units may not have the correct software for use with
open array scanners and will therefore require upgrading.
The software version can be confirmed by switching-on the dis-
play and checking the version number during the magnetron
warm-up sequence.

This handbook is divided into three chapters as follows:
Chapter One provides an overview of the scanner installation. It
includes sections on Unpacking and Inspecting the Components,
Selecting the Scanner Site and a description of the Cable Runs.
Chapter Two provides detailed instructions on how to mount and
connect each type of scanner.
Chapter Three provides instructions on how to perform the system
checks, alignment and adjustments. It also provides information on
maintenance and what to do if you have problems.
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 is required to ensure that performance is not
compromised. 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.
The guidelines given here describe the conditions for optimum EMC
performance, but it is recognized that it may not be possible to meet
all of these conditions in all situations. To ensure the best possible
conditions for EMC performance within the constraints imposed by
any location, always ensure the maximum separation possible
between different items of electrical equipment.
For optimum EMC performance, it is recommended that wherever
possible:
•
Raytheon equipment and cables connected to it are:
•
At least 1 m (3 ft) from any equipment transmitting or cables
carrying radio signals e.g. VHF radios, cables and antennas.
Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 1: Overview
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 informa-
tion 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.

the Radome Scanner includes instructions on fitting a ferrite.
The following illustration shows a typical range of suppression
ferrites fitted to Raytheon equipment.

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 ship’s battery negative. If you can-
not do this, and encounter problems, you can fit insulating bushes be-
tween 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 per-
sonnel, preferablyaboveheadheight. Thisavoidsmechanical
danger and electromagnetic contact, particularly with the
eyes.
•
•
Radar operates at the line-of-sight, so a high mounting posi-
tion gives better long range performance.
Surrounding large objects, in the same horizontal plane, can
interferewiththeradarsignalandcause blindareasorshadow
sectors and false targets on the radar screen (see below).
However, do not mount the scanner so high that it is affected by
thepitchingandrollingofthe vessel. In addition, youmayneedto
lower the scanner to avoid creating a shadow sector underneath
the scanner’s beam.

•
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 con-
sidered, refer to Section 1.4 Cable Runs to determine appropriate
lengths.
•
Shadow sectorsandfalseechoes:Mount thescannerawayfrom
large structures or equipment, such as the fly bridge, large engine
stacks, searchlights, horns, ormasts. It isparticularlyimportantto
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
ofthebeamintensity, althoughnotnecessarilyacompletecut-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 bear-
ing 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. Thisinformationshouldbe posted nearthe 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:
•
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 (2½ in). When using the mast mount kit, appropriate
hardwareshouldbeusedforthestyle andstructureofthemast 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
properradarguardthemountingplatformandtheradarscannercould
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.

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.

Waterline
Ideal Radiation Plane
D3223-2
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.

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.
Avoidcuttingandre-joiningcables(ifnecessary,refertothenotes
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
otherend of the radome scanner cable isfitted withan 8-way plug
and power cores (covered by a clear protective sleeve) for con-
necting to the scanner.
For open array scanners, various length cables are available.
These cables have a connector plug at one end for connecting to

Powercable. Thescannerreceivespowerviathedisplayunit;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 Raytheon 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.

Pathfinder Radar Scanners
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.
On an open array scanner, the junction box should provide a 13-way
terminal strip with a 20A 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 ismountedon ahollow mast the cable maybe run insidethe 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:

Radome scanner cables
Inter-unit 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
minimize 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 scannertype (18" radome or24" radome), andthe
cable type (2 or 4 power cores): if a mix of light and heavy cables is
used, only 2 power cores are connected through.
Note: For vesselswith 24 V powersystems, 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 the table.

Power cable
The radome radar systems are intended for use on ships’ DC power
systemsoperatinginthe 10.7to32V DCrange(thatis, 12V and24V
systems, not 32 V systems). A 1.5 m (5 ft) power cable is supplied
(withthedisplayunit)forconnectingtheship’sDCpowertotheradar
scannerviathedisplayunit.RefertotheHSBSeriesDisplayOwner’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 endto the extension cable. The supplied power cable
2
has a cross-section of 2.0 mm .
Note: For vessels with 24 V power systems, the power cable may be
2
extended by up to 20 m using a wire gauge of 1.5 mm (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 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’smainpowersource andtheconnectorblock, andthenselectthe
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
2
the 10 m entry, in the column for 4.0 mm wire gauge.

Open array scanner cables
Inter-unit cable
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,
bothhave 4 powercores to minimize voltage dropsover 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.

24 V and 32 V Systems - 10kW scanners
10 kW open array scanners can use any combination of inter-unit
cable up to a maximum length of 35 m. However, these systems use
considerable power and installations should be planned to minimize
all cable lengths. Refer to the tables on page 1-19, Max. Extension
Power Cable Lengths (m) - 10 kW Scanner.
Power cable
The open array scanner systems are intended for use on ships’ DC
power systems operating in the following ranges:
4 kW
10.7 to 44V DCrange (that is, 12V, 24V and 32V systems)
10 kW 20 to 44 V DC range (that is, 24 V and 32 V systems).
CAUTION:
10 kW open array 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.
Open array scanners draw considerable power from the vessels
power source, especially in high wind speeds. It is essential for
reliableoperationthattheunitissuppliedwithalow resistancepower
cable system, especially when operated from a 12 V power system.
CAUTION:
Do not use the 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 (4 kW scanners only)
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
isolatorswitchviaitsowndedicatedcablesystem.Itisrecommended
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 MUST be included in the power
cable.
All power connections must be of high quality to minimize their
resistance and to remove the riskof accidental shorts. Recommended

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.

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 il-
lustration 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.
WARNING:
Support the pedestal unit until it has been secured to the
mounting platform. It is important that all four sets of nuts and
washers areused tosecure the pedestal tothemounting platform.
6. Referring to the following illustration, use the four nuts and asso-
ciated washerssupplied to secure the pedestal. Tighten the nuts to
20 Nm (14.7 lb ft); ensure the scanner is tightly fitted.
Grease the nuts.

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.
Power Connections
Thepowerconnectiontotheradarshouldbe madeateitherthe output
of the battery isolator switch, or at a DC power distribution panel.
Raytheon 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.

Chapter 3: Post Installation Checks and
Maintenance
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. In addition, for a 72" open array scanner you need to
set the antenna size to ensure the scanner rests in the correct position
when rotation stops.
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.
EMC Conformance
Always check the installation before going to sea to make sure that it
is not affected by radio transmissions, engine starting etc.
3.1 System Checks and Alignment
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 yourauthorised installationdealer tocheck theinstalla-
tion before going to sea.
Set up, alignment and timing checks
Switch on and initial set up
On the open array scanner, ensure the power switch on the pedestal is
set to ON.

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.
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
alignmenttoensurethattargetsappearattheircorrectbearingrelative
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.
It is advisable to check the display timing before using the system for
navigation.
72" open array position alignment
To ensure the 72" open array scanner rests in correct position when
rotation stops, you need to adjust the radar set up as follows:
1. With the display switched on in Radar mode, press MENU then
press the RADAR SET UP soft key.
2. Use the cursor to select the ANTENNA SIZE option, then press the
6 ft softkey.
press ENTER twice to return to the default display.
If the Radar Set Up menu option ANTENNA SIZE is not available,
then you have an older version of display software. The 72" open
array scanner will operate correctly with this display. However,
for details on adjusting the open array stopping-position, please
contact your authorised Raytheon dealer or distributor.

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
attempttoservice theequipment. Theoperatorshouldnot remove
the rear cover of the display or any internal covers in the scanner.
Alwaysturn the radarsystem off before carryingoutany 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 Ray-
theon service technicians. They will ensure that service proce-
dures 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 equip-
ment.
When powered, all electrical equipment produces electromag-
netic fields. These can cause adjacent pieces of electrical equip-
ment 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

enable you to ensure minimum interaction between different
items of equipment, i.e. ensure optimum Electromagnetic Com-
patibility (EMC).
•
•
Always report any EMC-related problem to your nearest Ray-
theon dealer. We use such information to improve our quality
standards.
In some installations, it may not be possible to prevent the equip-
ment from being affected by external influences. In general this
