OPERATING PRECAUTIONS
WARNING
Do not place heavy objects on the receiver unit. Failure to observe this
warning could result in the unit becoming unbalanced and thus causing injury if
it falls.
Do not place heavy objects on the power cable or the antenna cable. Failure
to observe this warning could result in fire, electrical shock, product trouble,
and/or receiver signal deterioration.
Do not operate at voltages other than 10.8 - 35.0 VDC. Failure to observe this
warning could result in fire, electrical shock, and/or malfunction.
If an unusual smell, smoke, or other abnormality is detected, immediately turn
off the power to the unit and then turn off the power on the power distribution
panel of the vessel. After confirming that the unusual smell, smoke, or other
abnormality has cleared up, consult your dealer or nearest JRC service/sales
representative for repair. Continued use while the abnormality persists may
cause fire and/or electrical shock.

iv
OPERATING PRECAUTIONS
CAUTION
Do not place the receiver unit on an unstable surface. If placed on an unstable
table or an uneven surface, it could fall and result in personal injury and/or
damage or malfunction of the unit.
Secure the unit sturdily using the supplied screws.
Do not expose to water or moisture. Placement on exposed decks or in humid
places may cause electrical shock or product malfunction.
Do not open or remove the cover of the unit. Touching the parts inside could
result in electrical shock. If it is absolutely necessary to check the interior of
the unit for maintenance purposes, turn off the power switch on the power
distribution panel supplying its power.
Avoid exposure to direct sunlight, heat, moisture, and dust. Failure to do so
may cause fire, malfunction, and/or deterioration of print-out quality.
Always use the JRC-recommended printer paper. The use of any other paper
may cause printer trouble and/or deterioration of print-out quality.
When cleaning, do not use benzene, alcohol, thinner, or other volatile solvents.
These solvents may damage or cause deterioration to the coated surface.
Wipe the surface lightly with a soft cloth.

v

GLOSSARY
(1) NAVTEX Broadcasts
Maritime safety information that consists of navigational alert information, meteorological alert
information, and search-and-rescue information broadcast from coastal stations at a frequency of
518 kHz.
Alpha-numeric characters are broadcast narrow-band direct printing telegraphy in accordance with
predetermined transmission schedules.
These broadcasts cover a range of 400 nautical miles from coasts.
(2) Total Navigator (ECDIS)
Electronic chart system for navigational surveillance.
(3) Integrated Radio Communications System (IRCS) for Vessels
A system that connects GMDSS (Global Marine Disaster Safety System) equipment to a digital
interface network and provides integrated communications management using a GMDSS workstation.

CHAPTER 1
EQUIPMENT OVERVIEW
1.1 FUNCTIONS
οThe receiver (usually referred to as the equipment in this manual) executes the NAVTEX
function that automatically receives and prints out NAVTEX service broadcasts supplied in
English.
οThe NAVTEX function receives and prints out the various types of information broadcast at a
frequency of 518 kHz, such as: navigational alert information, meteorological alert information ,
search-and-rescue information, and other types of information. The equipment also provides a
method of programming so that you can select the type of information to be received and from
which receiving station to receive it.
1.2 FEATURES
οReceiving NAVTEX broadcasts
The equipment receives NAVTEX broadcasts automatically.
οReduced consumption of printer paper
Since the equipment has the capability of storing up to 128 message identification codes in
memory for up to 72 hours, duplicate printing of messages is avoided.
οPermanent storage of data settings
Once the types of messages to be received and their receiving stations have been set, these
settings are automatically stored into the internal memory (EEPROM) of the equipment. The
data, therefore, does not require re-setting, even after power has been turned off.
οHigh reliability based on digital demodulation
JRC’s unique digital demodulation circuit ensures high reliability.
οDual voltage supply input
The equipment can be used on either 24-VDC vessels or those with 12-VDC.
οSelf-diagnostics
The equipment contains self-diagnostic tools, making it easy to service.
οConnection to external equipment
The equipment can be used in conjunction with Integrated Radio Communications System
(IRCS) for vessels and the Total Navigator (ECDIS).

1.3 CONFIGURATION
The equipment consists of a main unit (NCR-330) and an antenna (NAW-330).
Although it operates on DC power, operation on AC power is also possible with an optional power
supply unit (NBG-4534A or NBG-122). Also, an external alarm buzzer can be attached so that the
alarm can be heard at remote locations when search-and-rescue information is received through
NAVTEX broadcasts.
In addition, it can be used in conjunction with the Integrated Radio Communications System (IRCS)
for vessels and the Total Navigator (ECDIS).
The overall configuration of the equipment, including major peripherals, is shown below.
