1. OPERATION

1.1 System Overview

The radar sensor transmits pulses of micro­wave energy that bounce off any object in
their path. The object returns a tiny part of the
wave's energy to the radar sensor. Radar de­termines the distance to a target by calculat­ing the time difference between the trans­mission of a radar signal and the reception of
the reflected echo. The bearing to a target
found by the radar is determined by the direc­tion in which the antenna is pointing when it
emits an electronic pulse and then receives a
returning echo.

The radar sensor forwards the returning ech­oes to the iOS terminal (iPhone, iPad), using
its wireless LAN module. The radar applica­tion in the iOS terminal displays the radar ech­oes on the terminal’s display and provides
controls for adjustment of the radar picture.

3.2 Installation Considerations

General considerations:

• Do not apply paint, anti-corrosive sealant or contact spray to coating or plastic parts. Those items
contain solvents that can damage coating and plastic parts.

• The radar sensor has no power switch. Therefore, it is recommended that you connect the sensor
to a disconnecting device (circuit breaker, etc.) to control the power.

Sensor placement:

• The radar sensor uses the 2.4 GHz wireless LAN radio band to forward radar echoes to the iOS
terminal. Separate the sensor well away from products which also use this band (microwave
range, Bluetooth devices, etc.) to prevent mutual interference.

• Install the radar sensor on the hardtop, radar arch or on a mast on an appropriate platform. (For
sailboats, a “radome mount” is optionally available for fixing the sensor to a mast.) Place the sen­sor where there is a good all-round view with, as far as possible, no part of the ship’s superstruc­ture or rigging intercepting the scanning beam. Any obstruction will cause shadow and blind
sectors. Be sure there are no metallic objects near the antenna. See the next page for typical
placement on a sailboat and powerboat.

• Observe the wireless LAN communication range noted in the illustration on the next page.

• In order to reduce the chance of picking up electrical interference, avoid where possible routing
the power cable near other electrical equipment onboard. Also, avoid running the cable in parallel
with other power cables.

• Select a location that does not allow water to accumulate at the base of the sensor.

• A magnetic compass will be affected if the radar sensor is too close to the compass. Observe the
compass safe distances mentioned on page ii to prevent interference to a magnetic compass.

3.3 How to Install the Radar Sensor

Determine the suitability of the mounting loca­tion BEFORE permanently mounting the sen­sor. Incoming and outgoing signals may
overlap one another depending on the shape
of the vessel, preventing communication be­tween the terminal and the sensor. Set the
sensor on the selected location and connect
the sensor to the power source. Turn on the
sensor. Open the terminal, turn on the radar
application and try to connect the terminal to
the sensor (see section 3.4.1 for how to start
the system). If the connection is successful,
change the range to check if the sensor re­ceives your command. Check that the picture
is updated with each sweep. Some trial and
error may be necessary to find a suitable loca­tion.

Guidelines for laying the power cable

• The connectors must not strike any part of
the vessel by wind, etc.

• The load applied to the connectors must
not be more than its own weight.

• If the cable is passed through a mast on a
sailboat, be sure the cable does not touch
ropes (sheet, halyard, etc.).

• Do not fasten the cable to the hull.

• The cable must be fixed so no tension is ap­plied to the connectors. To prevent tension,
create a loop in the cable close to the sen­sor and tie the loop with cable ties, as in the
figure below.

3. INSTALLATION

Heading line

Heading alignment

You have mounted the radar sensor facing
straight ahead in the direction of the bow.
Therefore, a small but conspicuous target
dead ahead visually should appear on the
heading line (zero degrees).

In practice, you will probably observe some
small error on the display because of the diffi­culty in achieving accurate initial positioning
of the sensor. The following adjustment com­pensates for this error.

1. Open the menu, Picture menu:

1) iPad: Tap the menu tab at the bottom
right corner to open the menu.
iPhone: Tap anywhere to open the
menu.

2) iPad, iPhone: Tap the ( ) icon to
open the Picture menu.

0.125 to 0.25 miles.

4. Point your boat’s bow directly toward the
target selected at step 3.

5. Locate the target selected at step 3 on the
display and choose a range which places
the target in the outer half of the picture.

6. Adjust the slider bar so the target be­comes centered on the heading line.

3.4.5 Sector blank

A sector blank is an area on the radar display
where no radar echoes appear because an
obstruction near the radar sensor (for exam­ple, a mast) blocks reception within that area.
This area should be marked on the display to
alert you that no echoes will be shown there.
If you do not have this problem, skip this pro­cedure.

As an example, the procedure below shows
how to set a 20° sector blank between 170°
and 190°.
