present even after the power switch has been turned off.
Power source, fuse and power cable
The radar scanner will get its power from the display unit. Ensure that the
power cable is firmly attached to the appropriate port on the display unit.
Note: the appropriate fuse(s) must be employed, see fuse rating in the
specifications.
Maintenance safety
Beware of residual high voltages
High voltages may remain in the capacitors several minutes after you have
turned the power switch off and disconnected the cable between the radar
scanner and display unit. Wait for at least five minutes or discharge them to
ground before starting your inspection.
Main power supply must be disconnected
To prevent electrical injury due to erroneous power switching, make sure that
the main power supply and the system power switch are both OFF. Also attach
a safety label showing that service is in progress.
Avoid inhaling dust
When cleaning inside of the equipment, avoid inhaling the dust, as it could be
a temporary health hazard.
Avoid static electricity
Take care not to damage the ESDs (Electrostatic Sensitive Devices) due to
static electricity from carpeting and clothing.
Routine check
Periodically check that the scanner’s mounting bolts are tight and not cor-

roded. Every 6-12 months an even coating of grease should be applied to the
entire surface of the scanner drive gear with a spatula or brush. Most of the
maintenance of the radar scanner should be left to qualified personnel. If there
are problems with the performance, please contact your authorized dealer.
Surface cleaning
Wipe the scanner surfaces with a clean damp cloth. For heavier cleaning, use
a clean, damp cloth which has been dipped in a solution of mild dish detergent
and water. Wring out firmly before wiping the scanner.
)Never use cleaning solutions containing spirit, alcohol, gasoline or oils.
Repair and service
There are no user serviceable parts in the radar scanners. Unauthorized
handling of the scanner will void its warranty. If your radar scanner requires
servicing or repair, call your authorized SIMRAD dealer, but first check

1.2 How to determine the site of installation
A radar’s target detection capacity varies greatly depending on the fitted posi-
tion of the scanner. An ideal fitting position is a location high above the ship’s
keel line where there is no obstacle all around the scanner. In an actual ship,
such an ideal location is limited by various factors. Therefore, consider the fol-
lowing suggestions when you determine the place to install the scanner:
A. Install scanner away from smoke-stack and mast
If the scanner is installed at the same height as the smoke-stack or mast, radar
waves may be blocked, crating shadow zones or generating false echoes.
Therefore, do not install the scanner at such a position.
B. Install scanner forward away from obstacle
To avoid creating shadow zones or generating false echoes, install the scanner
at a position nearer to the ship’s bow away from obstacles. When installing
the scanner on a mast, position it in front of the mast. If obstacles cannot be
avoided for the ship’s structural reasons, refer to “Shifting away from obsta-
cles” described in section 1.2.1.
C. Do not install the scanner near hot or heat-generating items
Do not install the scanner at a position where it may be subjected to smoke or
hot air from smoke-stacks or heat from lamps.
D. Install the scanner away from antennas or other equipment
Install the scanner as far away as possible from the antennas of a direction
finder, radio transceiver, etc..

1.2.1 Shifting away from obstacles
Shifting from keel line: By shifting the scanner position from the keel line to
the starboard side of the ship, it is possible to move shadow zones to the port
side which makes it possible to keep a clear vision in the bow direction. The
distance to be shifted can be obtained by calculation depending on the dis-
tance from the scanner to obstacles using the following equation:
Ls=0.4R+D/2 [m] (when R<15 m)
Ls=0.025R+D/2 [m] (when R>15 m)
where Ls= distance to be shifted from keel line
D= diameter of obstacle on keel line
R= distance from scanner to obstacle
Scanner unit Obstacle
Keel line
Obtaining sufficient dip angle: Raise the scanner position so that there is a
sufficient dip angle available between the line of sight from the scanner to the
obstacle and the horizontal line. By raising the dip angle above 5° it is pos-
sible to prevent mid and long distance shadow zones. The radar cannot detect
objects below the line of sight.

1.2.2 Mounting of scanner
Deciding the place of installation, a minimum distance must be considered to
the master compass (2 meters) and steering compass (1.4 meters). If a mount
base like the one shown below is available, it may be easier to install the
scanner. If not available, you may install the scanner directly to the roof, etc.
In this case, pay attention to the water drain tube located at the bottom of the
scanner unit during installation.
)When the radar mast or mounting bracket has a curvature of more than
2 mm, repair it or use spacers.
Mount base Do not use an edge that might trap water
Which size bolts to use for mounting of scanner unit:
Thickness of mount base Bolt requirement Material Remarks
1-4 mm (0.04-0.16 in.) M10 × 15 (1.5 mm pitch) Steel

1.2.3 Connecting cables
(length of cables – see chapter 4. Specifications)
Run the cables by following the instructions below:
• Do not bind the cable for the radar collectively with cables of other equip-
ment (especially the power supply cable).
• Run the radar cable along the ship’s hull or wall surface, and fasten it at
intervals of about 40 cm.
• The scanner side of the radar cable has to be fitted inside the radome
scanner, see Interconnecting cable next page.
• The power cable delivered with the display unit must be fitted with two fuses
before connecting the radar scanner (see fuse types in specifications).
• After fitting the Interconnecting cable:
The radar cable has a connector fitted on the display side. Push the connec-
tor as far as it will go into the receptacle marked ‘RADAR’ on the rear of the
display cabinet and turn the connector’s coupling ring clockwise until it is
tight.

2. Initial start-up of radar function
Having completed the installation of the scanner and display units and con-
necting cables, refer to the operator manual for the display unit for initial start-
up of radar function and operation in general.
2.1 The scanner needs to warm up
Starting up for the first time after installation or after long storage (6 months),
the scanner will need an extra 20 minutes to warm up, so after Power on and
going into Standby, the radar function must be left in Standby mode for the
extra 20 minutes it will take to properly warm up the scanner. This way you
will contribute to the lifetime of the magnetron in the radar scanner.
Note: Normal start-up at regular usage will take approx. two minutes for the
scanner to warm up and be ready for transmission.
