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.

obstructions.

CAUTION

Avoid bundling the antenna of the NAW-330 together with any other antennas.

Failure to observe this caution may cause deterioration of the signal to the

receiver due to noise radiated from other antennas. Further, noise radiated

from the antenna of the NAW-330 could cause signal deterioration to other

equipment.

Avoid routing the antenna cable near other cables such as power cable,

transmission antenna cables, or radar waveguides. Noise induced to the

antenna cable could deteriorate the receiver signal.

Do not install the whip antenna in a place exposed to strong vibration.

Antenna damage could result.

The connectors of the antenna cable must be waterproofed. Further, the

antenna connectors of the NAW-330 float from the ship earth could cause turn

on the earth lamps due to contact with the ship earth use battery power source.

Criteria for antenna site

(a) Using a pole up to 9 cm in diameter and resistant to hull vibration

If the antenna is to be mounted using a pole such as a handrail, reinforce the pole by providing

stays so that the antenna can maintain its initial anti-vibration characteristics.

(b) There should be no obstructions within a radius of 1 meter of the installation location. The

presence of any obstructions may bring the whip antenna into contact with them if it is swung

significantly by the wind.

(d) The installation location should be sufficiently distanced from the antenna of the transmitter.

CHAPTER 6

MAINTENANCE AND INSPECTION

6.1 MAINTENANCE

To maintain the equipment always in its best condition, it is important to perform maintenance

checks and record the results. Thus, potential problems can be detected early and trouble can be

avoided.

6.1.1 Daily check

Without printer paper, you cannot obtain necessary information. Therefore, check the remaining

quantity of printer paper as follows:

(1) Open the paper cover on the front panel.

(2) Check the quantity of printer paper remaining. If red lines appear at the edges of the

paper, replace it with a new roll (the red lines indicate there is one meter or less

remaining).

(3) If there is a sufficient quantity of paper, or after a new roll of paper has been set, close

the paper storage cover.

6.1.2 Periodic check

The self-diagnostic tests check the status of each function of the equipment on a per-block basis.

Conduct periodic checks as directed below.

(a) Operating procedure

See Section 5.5, Self-Diagnostic Tests, for further details.

(b) Self-diagnostic tests

Self-diagnostic tests begin with testing of the receiver/demodulator circuit and end with testing

of message-processing. The results are printed out, and if the tests detect no abnormalities,

the print-out will look like this:

The contents and results of diagnosis are in the following.

1) Receiver/demodulator circuit tests

A loop test of the receiver circuit is executed. When this check is completed correctly, it

prints as following:

“518kHz Receiver: Good”

If any errors are found, the following error message is printed:

“518kHz Receiver: Failed”

･･････････ Press “ALARM OFF”････････････

･･･････････････Self Test End･･･････････････

2) ROM tests

A test of the computer and memories are executed. When this check is completed

correctly, it prints as following:

“Main Processor: Good”

If any errors are found, the following error message is printed:

“Main Processor: Failed”

3) Message-processing tests

Loop tests are carried out to check for normal operation of the processes from NAVTEX

message receiving to printing. The RECEIVE and ALARM lamps blink during normal

execution of the tests.

When this check is completed correctly, it prints message identification code as following:

“ID00”

If any errors are found, the message is not printed.

･････････Main Processor : Failed

･････････

･･･････････ Press “ALARM OFF”･･･････････

･･･････････････Self Test End ･･･････････････

･････････････ Overall Test Start ････････････

4) Other checks by the self-diagnostic tests

a. Checking the receiving tone

During tests, if the equipment is normal, a soft tone will be heard. If this tone is not

heard, or if the tone is unusually loud, either the CMN-2330 receiver board or the

CDJ-2330 is likely to be malfunctioning.

b. Checking the alarm buzzer sound

During message-processing tests, if the equipment is normal, the alarm buzzer will

sound. This alarm can be deactivated by pressing the ALARM OFF switch. If the

alarm does not sound or if it is unusually loud, either the CMN-2330 receiver board

or the CDJ-2330 main processor board is likely to be malfunctioning.

After the alarm has sounded, if it cannot be deactivated using the ALARM OFF

switch, either the H-7SZJD0002A main switch or the CDJ-2330 main processor

board is likely to be malfunctioning.

c. Lamp tests

The lamps on the front panel blink for about three seconds prior to the start of the

message-processing tests.

During the tests, if the equipment is normal, all LEDs other than POWER will blink

at intervals of about 0.5 seconds. If blinking is abnormal, the H-7SZJD0002A main

switch or the CDJ-2330 main processor board is likely to be malfunctioning.

Also, the alphabetic display unit will display characters A to Z. If the display is

abnormal, the CDJ-2330 main processor board is likely to be malfunctioning.

6.1.3 Other general maintenance and check items

In addition to periodic checks by the self-diagnostic tests, it is recommended to check the

following periodically.

CAUTION

When loading the printer paper, cut the leading edge straight. Uneven cutting

may cause the paper to jam.

NOTE:If the “out of paper” alarm activates to warn of paper outage, the receiver cannot be

reset to stand-by status just by adding paper. The alarm must be cleared by

pressing the ALARM OFF switch after adding paper.
