Check
Dthe ALARM−Messages (detailed information
see chapter 2.3.6.4).
Dthe position indication between radar information
panel and position sensor.
Dthe radar video with the real area, make a bearing
to a known target (bouy, beacon, church).
Dthe magnetron quality. Check it with the performance
monitor (see chapter 2.5.5).
PPI adjustments
Select your required Range Scale (highest value
96.0 NM, lowest value 0.125 NM).
Fade the Range Rings, Rings are used to make quick
assessment of target’s approximate range from own ship.
The ship symbole appears in the range scale between
0.125 NM to 96.0 NM or in the ring scale
0.02 NM to 16 NM.
SITUATION SETTINGS
Antenna Sensitivity controls
AUTO mode for TUNE.
The TUNE control is used to tune the Receiver
Frequency to match that of the Transmitter.
The tune adjustment should be made on the
medium or long range scales that show radar returns.
The GAIN control adjusts the sensitivity of the radar
display.
AUTO mode for SEA, RAIN, FTC (SFAR).
The SEA control is used to suppress radar returns which
are the result of radar signals reflected from waves.
The RAIN control is used to suppress radar returns
which are the result of radar signals reflected from rain
drops.
FTC performs differentiating, or filtering of rain clouds.
Search and rescue transponder SART ON is to improve
detection of SART.
Select the puls length, from short to long pulse and vice
versa to optimize the target discrimination with respect
to selected range.
Select the interference function (ON or OFF).
Select the echo expansion (ON or OFF).

IMPORTANT NOTICE AND SAFETY INFORMATIONS
This Radar is an aid to navigation. Its accuracy can be affected by
many factors such as equipment defect, environmental conditions, or
improper operation. It is the user’s responsibility to exercise common
prudence and navigational judgement at all times.
This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant IEC 60936 to IEC 60872, IEC
60945.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial
environment.
This equipment generates, uses and can radiate radio frequency en-
ergy and, not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. Operation
of this equipment in a residential area is likely to cause harmful inter-
ference in which case the user will be required to correct the.
interference at his own expense.
ATTENTION

3748DOC020102 Edition: 14.JAN.2005
There is absolutely no danger in handling the external controls of the radar
while the radar is in operation. In the radar‘s interior, however, are high
voltages which are fatally dangerous to anyone careless handling interior
components. Be absoluteley sure that the radar power switch is OFF before
performing repair work or maintenance .
Furthermore, even when the power switch is turned off, a high voltage remains
in certain parts of the radar circuits. In particular, be careful of the magnetron
heater circuit, cathode−ray tube anode circuit, etc.. Utilizing a length of wire
with one end fully grounded or an insulated srewdriver, ground all high voltage
sections to discharge the residual charges and ensure that no charges remain
before touching any part of the high voltage sections. In any case, the most
dangerous thing to do is to touch any part of the high voltage sections without
making sure that the radar power switch is off.
HIGH VOLTAGE
Exercise care when approaching a rotating antenna. Be sure to turn off the
radar power switch before performing maintenance or inspection of the
antenna. Also, make sure that nothing or no one is near the antenna when
turning on the radar power supply.

A short exposure to the microwaves radiated by the radar antenna is harmless.
However, avoid prolonged exposure to the microwaves. Never look directly into the wave
guide while checking transceiver operation, since microwaves are especially harmful to the
eyes.
The radiation of microwaves can be checked with a neon tubel . The neon tube will glow in
the presence of microwaves.

for showing the NSC Radar System
chapter 2 for operation
short operation
chapter 3 for theory of operation
The NSC Radar is designed in accordance with the rules of the International
Maritime Organization IMO*.
* The International Maritime Organization is the specialized agency of the
United Nations with responsibility for safety and security at sea and the
prevention of marine pollution from ships.
The main components of the NSC Radar system include (see Figure: 1):
−the Flat Screen Display (TFT Technology)
−the Track ball, or alternatively the Radar Operator Panel to operate the Radar
−the Radar Processor which is, in addition to the NSC software, the interface to
the radar antennas (X/S−Band) and peripheral equipment (Gyro Compass,
GPS, Log Sensor, AIS, SART).
The operating surface of the NSC Radar:
The NSC Radar can be completely operated via the trackball−controlled cursor.
The Radar Operator Panel is designed for the execution of certain NSC func-
tions.
