ELECTRICAL SHOCK HAZARD
Do not open the equipment.
There are no user servicable parts inside.
Wear a safety belt and hard hat when

Serious injury or death can result if
someone falls from the radar mast.
The radar antenna emits electromagnetic radio frequency (RF) energy
which can be harmful, particularly to
your eyes. Never look directly into the
antenna aperture from a close distance
while the radar is in operation or
expose yourself to the transmitting
antenna at a close distance.

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.

1.2 How to Start, Stop the System
Power the radar sensor to activate the system. Open your iPad
or iPhone terminal and click the
[Marine Radar] application icon
(see right figure).
The splash screen appears for a few moments, then the application tries to connect to
the radar sensor, which normally takes no
more than three seconds. If the connection is
successful, the [Preheating] display appears.

If the connection
failed, the window
shown right appears.
Tap the [Search
again] button to try to
connect to the radar
sensor. If you cannot connect to the radar
sensor, check for interfering objects near the
sensor and make sure the wireless LAN function is enabled on your terminal.

Search again
The preheating stage, which warms the magnetron (the device responsible for transmitting
radar pulses), takes approx. 90 seconds. The
time remaining until the completion of the preheating is counted down at the center of the
screen. After the completion of the preheating, the STBY display appears.
To deactivate the system, disconnect the radar sensor from the power source.
Note: To connect an iOS terminal to another
DRS4W, reset the application first.

1.3 Transmit, Standby
Tap the [STBY-TX]
icon at the top right
corner on the screen
to put the radar in
standby, transmit
state alternately.
When you don’t need the radar, set it to standby to extend the life of the magnetron.
Note: The radar application is set to standby
when you switch to another application, or
there is no operation for one minute. However, the picture is continuously updated. The
notifications banner, which alerts you to received mail, etc., works while the radar application is active.

1.7 How to Adjust the Screen Tone
The screen tone (brightness) can be adjusted
to suit lighting conditions. Open the menu
then tap the ( ) icon. Drag the slider bar to
adjust the screen tone.
1.8 How to Select a Display Range
The range selects how far you want the radar
to “see”. The range selected automatically determines the range ring interval, the number
of range rings and pulse repetition rate. The
current range is shown at the top left corner
on the screen.
1.9 How to Reduce Rain Clutter
The antenna picks up rain
clutter (rain, snow, or hail) in
the same manner as normal
targets, as in the right figure. When rain clutter
masks targets, use the
[Rain] control to reduce the
clutter. The higher the setting the greater the
reduction of rain clutter
To adjust the rain clutter, open the menu then
tap the ( ) icon. Select the [Rain] screen.
Tap the [Manual] or [Auto] button. For manual
adjustment, drag the slider bar to reduce the
rain clutter.

1.10 How to Measure
the Bearing and
Range to a Target
(iPad only)
The bearing and range from own ship to a target can be measured with the cursor. Long
push the screen to show the cursor, which is
a cross (+). Drag the cursor to put it on the
center of the target. See the bearing and
range to the target in the [Bearing/Range]
box, which is to the side of the cursor. After
several seconds, the cursor is erased from
the screen.

1.12 Echo Stretch
On long ranges, target echoes tend to shrink,
making them difficult to see. To enhance target video on long ranges, use the echo stretch
feature to lengthen echoes in the bearing
and/or range direction.
Note: A slight difference exists between finger position and cursor position in order to
see the cursor while dragging it.
1.11 How to Off Center the Display
Own ship position, or sweep origin, can be
displaced manually or automatically to expand the view without switching to a longer
range. The maximum amount of shift is 75%
of the range in use.
To off center the display, drag the own ship
mark to the position you want to make the
screen center. To return to the normal display,
double tap the display area.
