How to discard a used battery

Some FURUNO products have a battery(ies). To see if your product has a battery, see the chap­ter on Maintenance. Follow the instructions below if a battery is used. Tape the + and - terminals
of battery before disposal to prevent fire, heat generation caused by short circuit.

In the European Union
The crossed-out trash can symbol indicates that all types of batter­ies must not be discarded in standard trash, or at a trash site. Take
the used batteries to a battery collection site according to your na­tional legislation and the Batteries Directive 2006/66/EU.

In the USA

The Mobius loop symbol (three chasing arrows) indicates that
Ni-Cd and lead-acid rechargeable batteries must be recycled.
Take the used batteries to a battery collection site according to
local laws.

In the other countries

There are no international standards for the battery recycle symbol. The number of symbols can
increase when the other countries make their own recycle symbols in the future.

SAFETY INFORMATION

Read these safety instructions before installing or operating the equipment.

WARNING

Indicates a potentially hazardous situation which, if not avoided,
can result in minor or moderate injury.

Warning, Caution

Prohibitive Action

CAUTION

Mandatory Action

Indicates a potentially hazardous situation which, if not avoided,
can result in serious injury or death.

Safety Information for the Operator Safety Information for the Installer

Wear a safety belt and hard hat when
working on the antenna unit.

Serious injury or death can result if
someone falls from the radar mast.

Do not open the equipment.

The installation does not require you
to open the radar sensor.

Be sure the power source is compatible
with the voltage rating of the equipment.

Connection of an incorrect power source
can cause fire or damage the equipment.

Turn off the power at the power source
before beginning the installation.

Fire, electrical shock or serious injury can
result if the power is left on or is applied
while the equipment is being installed.

WARNING

WARNING

ELECTRICAL SHOCK HAZARD
Do not open the equipment.

There are no user servicable parts inside.

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.

Distances at which RF radiation levels of
100, 50 and 10 W/m

exist are given in

the table below.

Do not disassemble or modify the
equipment.

Fire, electrical shock or serious injury can
result.

Wear a safety belt and hard hat when
working on the antenna unit.

Serious injury or death can result if
someone falls from the radar mast.

CAUTION

Observe the following compass safe
distance to prevent interference to a
magnetic compass.

It is recommended that you connect
the sensor to a disconnecting device
(circuit breaker, etc.) to control the
power.

N/A

Use the proper fuse.
Use of a wrong fuse can damage the
equipment or cause fire.

Do not depend one navigation device
for the navigation of the vessel.

For the safety of vessel and crew, the
navigator must check all aids available to
confirm position.

ii

WARNING LABEL

A warning label is attached to the sensor. Do not
remove the label. If the label is missing or
damaged, contact a FURUNO agent or dealer
about replacement.

CAUTION

Do not use high-pressure cleaners
to clean this equipment.

This equipment has the waterproof
rating outlined in the specifications,
at the back of this manual. However,
the use of high-pressure cleaning
equipment can cause water ingress,
resulting in damage to, or failure of,
the equipment.

NEVER handle, transport, or turn the
radome upside down unless the 4 large
flat washers and bolts at the bottom of
the radome are securely in place.

Since the transceiver inside the radome is
only taped to the bottom, the transceiver
can come loose, causing damage to the
RT unit and W-LAN antenna if the 4 bolts
and large flat washers are not in place and
secured.

The radar picture may not be updated
when the WLAN signal is weak.

If the WLAN signal is weak, discontinue
use of the sensor, to prevent trouble
associated with un-updated picture.

Keep the sensor and iOS terminal away
from products which use the 2.4 GHz
wireless LAN radio band (Bluetooth
devices, microwave range, etc.), to
prevent malfunction.

Discontinue use of the sensor if it receives
microwave interference.

The sensor cannot function properly if
there is trouble (equipment trouble, low
battery voltage, etc.) with the iOS
terminal.

For this reason, it is recommended to
keep more than one iOS terminal on
board in case of trouble.

operated and maintained properly. Please
carefully read and follow the recommended
procedures for installation, operation, and
maintenance.

We would appreciate hearing from you, the
end-user, about whether we are achieving our
purposes.

• Two iOS terminals can be connected to the
radar sensor at the same time.

• Guard zone alarm watches for targets en­tering or exiting an alarm zone.

• Echo stretch lengthens echoes in range
and/or bearing direction.

• Automatic adjustment of sea clutter
(echoes from waves), gain, noise and inter­ference.

• Off center feature lets you look focus on a
specific area ahead of or around your ves­sel without losing track of position.

• Self test checks the radar sensor for correct
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.

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.
