 Message Scrolling Keys 
  The keys that can be used to manually scroll messages across the current screen are 
indicated. 
  :  Line–by–line scrolling by pressing / 
  :  Message–by–message scrolling by pressing
/
 
  NOTE: When a type–D message (SAR, piracy and armed robbery information) is received, 
automatic scrolling will be disabled until the user acknowledges the message with or with 
a software command from an IBS /INS terminal via the rear–panel RS–422 connector. See 
paragraph 7.4 for details. 
 Receiver Operating Status Indication 
 The current status of receiver operation is indicated here. 
  ABORTED: The receiver has failed to lock onto the current transmission, due, for 
example, to weak signal level or noise interference. No message will 
be displayed or stored. 
  NOTE: Signal propagation conditions change greatly with time. You might 
not be able to receive a signal in the daytime that can be received at night; 
this is normal and should not be considered as a sign of receiver 
malfunction. 
  ACQUIRING:  The receiver is currently in the process of locking onto the start 
of the current message transmission. 
  LOCKED:  The receiver has locked onto current NAVTEX transmission, allowing a 
message to be received. As soon as the equipmet starts receiving the 
message, this indication will be replaced by RCVNG MSG. 
  RCVNG MSG:  The receiver is properly receiving a message after locking onto 
current transmission. This blinking indication will stay until the 
end–of–message code NNNN () is received.  
    NOTE: Whether to display or output the message to external devices 
depends on the character error rate (CER,  ) and on the 
selection/rejection settings to be made via the procedure in paragraph 4.8. 
  STANDBY: The receiver is idling, waiting for a NAVTEX message transmission to 
begin. Most stations transmit messages every 4 hours. 
 Operating Status Line 
  The current status of receiver operation, text scroll keys, etc. are indicated here. 
 Examples: 
  1ST RCVR MSG:   Message received on the first receiver is currently displayed. 
  2ND RCVR MSG:  Message received on the second receiver (490 or 4209.5 kHz) is 
currently displayed. 
  :  Message can be scrolled line by line by pressing /. 
  STANDBY:  Receiver is idling, waiting for a NAVTEX message transmission. See   
above for details.

  Message Identification (Message ID) 
  The ID of the currently displayed message is shown here. A red–colored ID represents a 
warning message. A message ID consists of the following elements: station ID, message 
type, and message serial number, as in the following example. 
  Figure 1-2    NAVTEX Message ID Format – Example 
 *1: ID of the transmitter from which the message was received. 
 Examples: J in NAVAREA  :   Gislövshammar, Sweden 
 F in NAVAREA  : Cape Cod/Boston, U.S. 
 I in NAVAREA  : Las Palmas, Spain 
 *2: Type (category) of this message (subject indicator) 
 Examples: A: Navigational warnings 
 B: Weather warnings 
 D: Search and rescue, piracy and armed robbery information 
 *3: Serial number of this message 
 Each message within the same category group is allocated a serial number between 00 
and 99 by each transmitter. A message with number 00 is always received on each 
transmission regardless of rejection settings, and will be displayed and stored in memory. 
 Alarm Tag IIALARM!III 
 This tag represents a visual alarm and is turned on when a NAVTEX message of one of 
the following types has been received. 
  Type–A Message:  Navigational warning (initially disabled) 
  Type–B Message:  Weather warning (initially disabled) 
  Type–D Message:  Search and rescue, piracy and armed robbery information. All text 
characters will be displayed in red to distinguish it from other type alarm 
messages. 
  Type–L Message:  Additional navigational warning (initially disabled) 
 NOTE: When a type–D message has been received, 
an audible alarm will also be turned on, beeping at 
approx. 1–second intervals. To silence the alarm 
sound, press . A second keypress resets the alarm 
and removes the alarm tag. 
  The alarm for the message types A, B and L is initially disabled. It can be enabled via 
SYSTEM MENU – 9:TURN ON/OFF MESSAGE ALARM. See paragraph 4.14 for details.

  This indication ( tag) shows that the currently displayed NAVTEX text is a new message 
that you have not yet read or acknowledged. 
  To acknowledge it, simply press   or , turning the tag off. 
  If two or more new messages have been left unread, the following caution message will 
be displayed at the screen bottom, prompting you to read them. Press  again to 
display, or scroll the text up to, the next one by pressing  /. 
 The NEW MESSAGE tag for the current message will be automatically removed 24 
hours after its reception, if it is left unacknowledged ( i.e. if  is not pressed). 
 NAVTEX Message 
  If message text exceeds the screen display area, you can scroll it line–by–line by 
pressing  /. Holding down either key accelerates the scroll. 
  To read other messages, press /
 (for message–by–message scrolling). Holding 
down either key accelerates the scroll. 
  Type–D messages (SAR , piracy and armed robber y information) will be displayed in red. 
A new type–D message will remain fixed on screen until: 
  it is acknowledged by pressing   or by means of a *1software command through 
an INS/ IBS terminal interfaced to the rear panel RS–422 connector, or 
  another new type–D message is received on either receiver. 
 *1: See paragraph 7.4.5 for details. 
 NOTE: Forced carriage return  
  When the number of characters in a line exceeds 40, an internally generated carriage return symbol, 
shown above, will be automatically inserted in the 40th character position to divide the last word, 
forcing the rest of the characters in the word to shift to the top of the next line. This symbol will be 
replaced by an underscore ( _ ) (hex 5F ) when it is printed or output to an IBS / INS device via the RS–422 
port. 
 End–of–Message Indication NNNN 
  The appearance of these four successive N characters indicates the end of the currently 
displayed NAVTEX message. 
  NOTE: Some messages including those from Chinese stations, end with NN  ( 2 Ns) instead of 
NNNN (4 Ns), in which case, the equipment will consider that the transmission has not 
ended properly, and will not, therefore, display and store such a message, or will append it to 
a new message, if received within a specified period of time, and display the two messages 
combined. The RS–232C port (printer port) may be set to output such messages. See 
paragraph 4.9 for setting instructions.

the internal non–volatile memory. 
  *1STORED:  The message has been stored. 
  When message reception has been completed with a character error rate (CER) of 33% 
or less, the received NAVTEX message together with its ID will be stored in memory, 
making it possible to recall it onto the screen at a later time. 
  If the same message is received with a lower CER on the next transmission, the 
previously stored message will be replaced with the new one. However, if the first 
message was received with a CER of 4% or less, message replacement will not take 
place on subsequent reception of the same message with a lower CER. 
 When the CER exceeds 33%, the message and its ID will not be displayed and stored in 
memory, allowing a retransmission of the same message to be displayed and stored. 
 *1: If the message selection/rejection settings are made so that a particular message type is 
rejected from storage, this indication will not be displayed regardless of a CER being smaller 
than 33%. See paragraph 4.9 for the related setting instructions. 
  Character Error Rate (CER) Indication 
 CER is the percentage ratio of the total number of corrupt characters represented by 
asterisks (*) to the total number of characters received in a message, including control 
codes (sync. signal, carriage returns, line feeds, letter/numeral shift, etc.),   
  If a message is received with a CER equal to or greater than 33%, it will not be displayed 
and stored in memory, allowing the same message to be received again on its next 
transmission. No CER reading will be available on the current transmission. See 
paragraph    for more information on CER. 
 Message Prompt Line 
  This line indicates the receiver’s response for the user’s keypress or displays prompts 
related to reception of new or alarm NAVTEX messages on the first or second receiver, 
or related to message storage, like the examples below.

3.1. Introduction 
This section describes the basic operating procedure, allowing you to operate your NAVTEX 
receiver from the front keypad without prior knowledge of the NAVTEX system. The 
functions that are available from the keypad are summarized in section 2 (Control Panel 
Functions). It is assumed that a specified antenna and appropriate power supply are 
connected to the equipment. 
3.2.  Turning the Equipment On/Off 
To turn the equipment on, gently press   once. 
 Figure 3-1    Opening Message – Example 
An opening message like the example at right 
will show up and stay for approximately five 
seconds, indicating the model name, software 
version number and release date. The numbers 
shown are examples. 
Turning Equipme nt Off 
 Figure 3-2   Power–Shutdown Countdown Window 
To turn the unit off, press and hold down  for 
two to three seconds until a power–shutdown 
countdown window shows up as illustrated at 
right, indicating that a power–off sequence has 
just started. 
 Keep on pressing the key until all countdown bars have disappeared, and then release 
the key to completely switch the unit off. This delayed action avoids an accidental shutoff 
and loss of message data. 
 Releasing the key with at least one countdown bar still showing cancels the 
power–shutdown sequence. 
Turning Opening Message Off 
  After the unit is switched on, the opening message window will be replaced with another 
window listing the current settings of receiver control parameters, as in the example 
shown in Figure 2–4. 
 The above list will stay on for approximately 20 seconds before the NAVTEX message

3.7. Stopping Audible and Visual Alarm 
Your equipment will warn you audibly and visually upon reception of a vital NAVTEX 
message (type–D message), such as SAR information, piracy, or armed robbery warning. 
An example type–D alarm message is given below, showing the visual alarm ( called the 
alarm tag) attached to the message ID.    The ID and text are also displayed in red to indicate 
that the message below is a type–D alarm message, distinguishable from other alarm 
messages (type–A: navigational, type–B: weather, or type–L: other alarm). 
Figure 3-8    Visual Alarm Indication for Type–D Message – Example 
To silence the audible alarm, simply press  . 
If another D type message was received before the current 
one, its audible alarm will also be stopped. 
Pressing the key again will turn off the visual alarm indication (iALARM!ii, alarm tag), 
resetting the alarm. 
A type–D message will remain fixed and will not automatically scroll until it is 
acknowledged or until another D message is received on either receiver. 
NOTE: Each alarm can be acknowledged and reset individually with the appropriate software 
command via the RS–422 port. See paragraph 7.4.5 for details. 
If additional alarm messages are left unread in 
memory, that condition will be indicated as in the 
example above. Pressing  again will recall the 
next unread alarm message onto the screen. 
  Figure 3-9    Visual Alarm Indication for Type–A Message – Example 
The equipment can also be set to alert you 
to a navigational warning ( type–A message), a 
weather warning (type–B message) or other 
warning (type–L message) via the menu 
system described in paragraph 4.14.

3.8.  Protecting Messages for Permanent Storage 
3.8.1. Introduction 
Initially, all stored NAVTEX messages will be automatically erased one by one from memory 
on a first–in–first–out basis as the equipment continues receiving new messages after the 
message storage capacity limit (200 messages) is reached. If you wish to protect a specific 
message for permanent retention in memory, proceed via the  steps given below.  Up to 
50 messages can be protected across each receiver screen, and are saved in a separate 
area of the non–volatile memory, allowing an additional 50 new messages to be stored in 
each of the first receiver and the selected second receiver. 
3.8.2. Protecting Procedure 
Figure 3-10    Protecting a Specific Message from Automatic Erasure – Step 1 
(1) Using /
and/or  /, display 
the message you wish to save. If two 
or more messages are being   shown, 
the ID of that message should be 
brought to the top message line, as in 
the example at right. 
Figure 3-11    Protecting a Specific Message from Automatic Erasure – Step 2 
(2) Press  . This will attach a message 
protection tag (PROTECTED tag) to 
the message ID as   in the example at 
right, indicating that the message is 
now protected against automatic 
erasure. 
  NOTE: If the message you wish to protect is a new message, the NEW MESSAGE tag will 
be replaced with the  PROTECTED tag. 
 Storage Limit Indication 
  Attempting to protect messages in excess 50 will cause the following error message to 
be turned on blinking in the message prompt line for a few seconds.

4.8.  Selecting and Rejecting Transmitters 
4.8.1. Introduction 
Initially the equipment is set to *1display NAVTEX messages from all stations on the air 
within the coverage area, *1store those messages in memory and output them to the 
printer port (RS–232C),  *2I/O DATA port and INS port (RS–422). There may be cases 
where you do not wish to display, store, or output future messages from specific 
transmitters that are not of your concern to your navigational needs. Carrying out the 
following procedure allows you to select or reject transmitters independently for message 
display and storage in memory, for message output to the printer port, and message for 
output to the INS port. 
A list of the transmitters that are currently rejected from display and storage can be checked 
by pressing    with the message screen showing. 
*1: A message will be displayed and stored in memory unless its character error rate (CER) 
exceeds 33%. CER is the ratio of the number of the correctly received characters to the number 
of corrupt characters per message. 
*2: The I / O DATA port (I/O DATA) outputs the same message output as the printer port. 
4.8.2. Setting Procedure 
To reject a specific station, execute the following step–by–step instructions: 
(1) Highlight option “4: MAKE SEL/REJ SETTINGS” by pressing  /, and then  . 
This opens a submenu as shown below with the following options: 
  1: SYNCHRONIZE BOTH RECEIVERS:  Applies same settings to both receivers. 
  2: FIRST RECEIVER (518KHZ):  Makes settings for first receiver alone. 
  3: SECOND RECEIVER:  Makes settings for second receiver alone. 
< CAUTION > 
 There are NAVAREAs where the same ID is shared by two transmitters, one on 518 
kHz and the other on 490 or 4209.5 kHz, located in two different countries in the 
same service area. In such cases, choosing option “1:SYNCHRONIZE BOTH 
RECEIVERS” will result in unintended rejection settings on either frequency.

If you wish to select some of these types for storage in memory or for output to the 
printer/ INS ports, or to prevent other messages types from being stored, or from being 
output to the ports, follow the procedure outlined below. 
NOTES: 
(1)  Message types A (Navigational warning), B (Meteorological warning), D (SAR, piracy and 
armed robbery information) and L (Additional navigational warning) are always selected 
for storage in memory, output to the printer, I/O DATA and INS ports; these types cannot be 
rejected (i . e .  cannot be set to the “ RJ” status). 
(2) A message with serial number= 00 will always be displayed and stored regardless of storage 
rejection settings. 
(3)  Those settings can be externally controlled via the INS port with appropriate commands 
from a PC or IBS/I NS device. See paragraph 7.4 for details. 
4.9.2. Setting Procedure 
To select some of the above initially rejected message types (e.g. type G: AIS messages) or

5. User–Level Troubleshooting 
A list of common troubles the user may experience while operating the equipment is given 
below along with recommended remedies for such troubles. If a problem persists, contact 
your dealer for assistance, giving as much information as possible about the symptom, 
self–diagnostic tests results (paragraph 4.13), power supply voltage, antenna configuration, 
operating frequency, control and menu settings used, serial number of, and *1software 
version (VER.) and revision (REV.) numbers of, your equipment. 
*1 The software version and revision numbers are displayed in the opening message window 
that appears briefly at power–up. Those data will also be displayed when the self–diagnostic 
tests are conducted (paragraph 4.13). 
< WARNING > 
HIGH VOLTAGES EXIST INSIDE THE EQUIPMENT CABINET. NO USER–SERVICEABLE 
PARTS ARE INSIDE THE CABINET. QUALIFIED PERSONNEL SHOULD MAKE IT SURE 
TO SWITCH THE EQUIPMENT OFF AND UNPLUG THE POWER CORD BEFORE 
OPENING THE CABINET FOR INSPECTION OR REPAIRS. 
5.1. Power–Up Problems 
The following description of the symptoms assumes that the equipment was working 
correctly for some time after its initial installation. 
Symptom  Suggested Solution 
The equipment cannot be turned on. 
1.  Check if the power cord is plugged into the 
three–pin rear panel connector ( POWER). 
2.  Check if the power cord is connected to the 
ship’s DC power source with the correct 
polarity. 
 NOTE: Reversing the power cord polarity causes 
the fuse (3A) to blow. 
3.  Check the voltage of the power source. 
 NOTE: The nominal power supply voltage is 24 
VDC. The equipment works safely over the 
voltage range from 11 to 36 VDC. 
4. Check the fuse inside the rear panel fuse 
holder. If it is found blown, replace it with a 
correct replacement ( 3A, 5.2X20mm). 
5. If it blows again, unplug the active antenna 
cable from the rear panel connector, and 
then check if the problem persists. If it does 
not, suspect that the antenna amplifier or the 
cable developed a short. Replace the 
antenna and cable. 
6.  If replacing the antenna still does not correct 
the problem, suspect that either the power 
supply PCB or the DC/AC inverter PCB has 
become defective. Ask your dealer/qualified 
engineer to check each board by 
replacement. 
7. If all attempts above fail, ask your 
dealer/qualified service engineer to replace 
the CPU PCB. 

AE-2000 Manual 
User-Level Troubleshooting

5.2. No Message Reception 
The following description of the symptoms assumes that NAVTEX messages were properly 
received for some time after initial installation. 
Symptom  Suggested Solution 
No messages can be displayed 
except for warning messages. 
No NAVTEX messages can be received, 
except for navigational warnings, 
weather warnings, SAR/piracy/armed 
robbery warnings or other warnings. 
1. Check the current message rejection (RJ) 
settings by pressing . 
2. Select all desired message types for display 
and memory storage, via the steps given in 
paragraph 4.9. 
No messages can be displayed 
from desired transmitters. 
No NAVTEX messages can be displayed 
from some transmitters at any time even 
if you are within the coverage areas. 
1.  Check the current station rejection (RJ) 
settings by pressing . 
2. Select the IDs of all desired transmitters for 
display and storage in memory, via the steps 
given in paragraph 4.8. 
No messages can be displayed 
despite correct selection settings 
and appearance of “RCVNG MSG.” 
No NAVTEX messages can be displayed 
regardless of the correct display and 
storage selection (SL) settings for all 
desired messages or transmitters, or 
regardless of the “RCVNG MSG” status 
indication during reception. 
1. The same message was received before or 
the currently receiving message has a 
character error rate (CER) > 33%.   See 
subparagraphs  ,   and  in paragraph 
1.1 for details. 
2. Run the self–diagnostic tests via the steps 
given in paragraph 4.13, and check if the 
receiver test result is “OK.” 
  If the test result indication shows “FAILED,” 
suspect that the corresponding receiver PCB 
has become defective. Ask your dealer or 
qualified engineer to check all wiring 
harnesses to/ from the PCB and to replace 
the PCB if necessary. The chance of any 
receiver being out of tune is very small in 
normal usage. 
3. Check if you are located within the service 
area covered by the ground wave of the 
desired station. The ground wave coverage 
normally extends to 200 – 400 nautical miles 
from each station during daytime hours. 
4.  Check the broadcast schedule of the desired 
station. Each station usually transmits 
messages for 5 to 10 minutes at intervals of 4 
hours. 
5. Check the active antenna unit and/or 
cabling by replacement. 
 (continued on next page) 
5.2. No Message Reception – 2/3 

AE-2000 Manual 
User-Level Troubleshooting 
 5-3
Symptom  Suggested Solution 
No messages can be received in 
the daytime. 
No NAVTEX messages can be received 
on 518 kHz or 490 kHz during daytime 
hours despite appropriate station and 
message type selection (SL) settings. 
1.  Check if you are located within the service 
area covered by the ground wave of the 
desired station. The area is normally 200 to 
400 nautical miles from each station during 
daytime hours. At night, MF NAVTEX signals 
( 518 / 490 kHz) can travel  distances in 
excess of 1000 nautical miles depending on 
the season and ionospheric conditions. 
Nighttime signal propagation is usually 
unstable, changing greatly with the season. 
2.  Check the broadcast schedule of the desired 
station. Each station usually transmits for 5 to 
10 minutes at intervals of 4 hours. Currently 
transmitting stations may be outside the 
coverage area. 
No messages can be received even 
during a broadcasting time and 
while in the service area. 
No NAVTEX messages can be received 
regardless of being in the service area of a 
currently transmitting station and of 
appropriate message type and station 
selection settings. 
1. Check if the antenna cable is correctly 
plugged into the appropriate rear apron BNC 
connector receptacle. 
2. Check if the connector (BNC) plug is 
properly installed onto the cable. Check also 
the coupling connectors, if used for cable 
extension. 
3.  Check by replacing the active antenna. 
 The antenna preamplifier unit may have 
been destroyed by static discharges. 
 If a correct replacement is not available, run 
at least 5 meters of insulated wire from the 
BNC connector’s center conductor as a 
temporary long wire antenna, and place it as 
high as possible from the ground level. 
< WARNING > 
 DO NOT SHORT THE OTHER END OF 
THE WIRE ANTENNA TO GROUND, 
OR DAMAGE TO THE UNIT’S POWER 
SUPPLY WILL RESULT. 
4. If replacing the antenna still does not solve 
the problem, check the voltage at the center 
conductor of each antenna connector. It 
should be 8V+ on the 490 and 518 kHz 
connectors, and 12V+ on the 4209.5 kHz 
connector.  If no voltage is present or if it is 
extremely low, ask your dealer/qualified 
engineer to check the wiring to / from the 
power supply PCB first and to replace the 
PCB, if necessary. 
5. If all attempts above fail to correct the 
problem, ask your dealer/qualified 
engineer to check the related connections 
to/from the CPU PCB first and to replace the 
PCB, if necessary.

5.2. No Message Reception – 3/3 

AE-2000 Manual 
User-Level Troubleshooting 
 5-4
Symptom  Suggested Solution 
No messages can be received at any 
time on the first or the second 
receiver with a good replacement 
antenna plugged in, but the results of 
the self–diagnostic tests are “OK” for 
both receivers. 
No NAVTEX messages can be received at 
any time and anywhere on either the 
first or the second receiver after  the 
antenna is replaced with one known to 
be good. The self–diagnostic tests 
(paragraph 4.13) show that both 
receivers are working properly. 
The symptom is an indication that the antenna 
circuit has become defective. 
1.  If the active antenna is used, replace it with 
one known to be good. 
2. If a correct replacement antenna is not 
available, run approx. 5 meters of insulated 
wire from the center conductor of the 
appropriate connector as a temporary long 
wire antenna, and place it as high as 
possible from the ground level. 
< WARNING> 
 DO NOT SHORT THE OTHER END OF 
THE WIRE ANTENNA TO GROUND, OR 
DAMAGE TO THE UNIT’S POWER 
SUPPLY WILL RESULT. 
3. If replacing the antenna still does not solve 
the problem, ask your dealer/ qualified 
engineer to check the antenna 
coupler/selector circuit inside the rear apron 
for faulty or broken connections. 
No messages can be received at any 
time on the first or the second receiver 
with a good replacement antenna 
plugged in, and the results of the 
*self–diagnostic tests are “FAILED” 
for both receivers. 
*  30 minute warm–up period required 
before test. 
1. The symptom suggests that both receivers 
have got out of alignment. Ask your 
dealer/qualified engineer to check the 
connections to/ from the receiver PCBs 
and/or replace the PCBs. 
2: The CPU PCB has also become defective 
and/or some of the internal connections to

Some stored messages disappear 
from memory after some time. 
Messages will be erased from memory after 60 
hours, unless they are protected from 
automatic erasure. 
Put the “PROTECTED” tag to each desired 
message via the steps in paragraph 3.8. 
None of the received messages is 
stored after power–off. 
The symptom indicates that the memory 
backup circuit on the CPU PCB is failing. Ask 
your dealer or qualified engineer to replace the 
CPU PCB. 
All messages disappear from memory 
after continued power–off for some 
time. 
The memory retains stored messages for at 
least 10 days after power–off. Print out desired

6.  User–Level Maintenance Instructions 
To ensure long–term trouble–free operation, the user should regularly follow the 
maintenance instructions described in this section. 
6.1.  Maintenance on the Equipment Cabinet 
Keep the equipment, away from sea splashes, direct sunlight and other heat–generating 
sources, and make sure that air around the cabinet is circulating freely. If the equipment is 
not going to be used for extended periods of time, dismount the cabinet  from the vessel 
and place them in dry storage. Be sure to switch the equipment off before removing 
electrical connections from the rear panel. 
< WARNINGS > 
1. HIGH VOLTAGES EXIST INSIDE THE EQUIPMENT CABINET WHEN IT IS 
ENERGIZED. BE SURE TO TURN IF OFF AND UNPLUG THE POWER CABLE 
BEFORE OPENING THE CABINET FOR INSPECTION. 
2. CHEMICAL SOLVENTS, SUCH AS PAINT THINNERS AND BENZENES, MUST NOT 
BE USED TO CLEAN THE CABINET OR SCREEN FILTER, OR PERMANENT 
DAMAGE TO THOSE PARTS WILL RESULT. 
3. ALL MESSAGES STORED IN MEMORY, INCLUDING PROTECTED ONES, WILL BE 
ERASED IF THE UNIT IS TO BE TURNED OFF CONTINUOUSLY IN EXCESS OF 10 
DAYS. IMPORTANT MESSAGES SHOULD BE PRINTED OUT OR SAVED INTO  
APPROPRIATE STORAGE MEDIA VIA A PC CONNECTED TO THE RS–422 PORT. 
To clean the cabinet surface, a neutral type household detergent intended for office 
equipment is recommended. Cleaning the acrylic filter on the LCD screen should be a 
maintenance routine to avoid using a high brightness level. To clean the screen filter, use a 
piece of slightly wet cloth. If stains persist, the cloth may be moistened with a neutral type 
household detergent. 
To prolong LCD Screen’s Service Life 
To increase the service life of the LCD screen (life of the fluorescent lamp for backlighting), 
it is recommended that the screen sleep mode be activated as per the instructions in 
paragraph 4.5. 
6.2.  Maintenance on Electrical Connections 
The high humidity marine environment can cause electrical contacts in the rear panel 
connectors to corrode over time. Vibrations and shocks normally encountered on the 
vessel in motion can cause the electrical contacts to become loosened. Corroded or loose 
contacts will become responsible for erratic, intermittent operation or performance 
degradation. To avoid such possible problems, conduct the following maintenance 
operations at least once a year: 
●  Unplug all the cables from the rear panel, and check to be sure that contact surfaces, 
including the pins in the rear–panel mounted receptacles are free from corrosion. 
●  Check the connections at the ship’s DC power source for freedom from any sort of 
corrosion. 
●  Correct any problem using a high quality contact–cleaning agent (contact rejuvenator). 
< WARNINGS > 
1. BE SURE TO TURN THE EQUIPMENT OFF BEFORE REMOVING / INSTALLING THE 
CONNECTIONS FROM / TO THE REAR PANEL CONNECTORS.

7. Installation 
7.1.  Receiver Cabinet Installation 
7.1.1. General Precautions 
The receiver cabinet is constructed to withstand the humid and corrosive marine 
environment, but is designed to be installed or operated inside the wheelhouse or 
chartroom. The cabinet is a “protected” category product under the IEC 60945–2002 
standard, and is not waterproof. Serious damage will result to the electronics inside the 
cabinet when it is exposed to salt water spray or splash. 
Additional Requirements: 
(1)  For long term trouble–free service, the proposed site for installation should be: 
  dry, well–ventilated and free as much as possible from shocks and engine vibrations. 
  away as much as possible from high temperature outlets (such as exhaust fans and 
heaters), and as much as possible from areas where the unit is likely to be constantly 
exposed to direct sunlight. 
(2) To prevent reception of weak NAVTEX signals from being interfered with, the unit should 
also be located away as much as possible from other onboard electronics, especially 
those emitting pulsed signals, such as echo sounders and radars. 
7.1.2.  Mounting the Receiver Cabinet 
The receiver cabinet is primarily designed to be mounted on a tabletop with the mounting 
bracket supplied and weights approximately 3.7 kg in total. The dimensions necessary for 
installation are given in Figure 7–2. Provide sufficient clearance behind the cabinet for 
cabling termination and maintenance checks. 
Using a total of four appropriate wood screws or bolt/nut combinations through its four 
mounting holes (9 mm in diameter each), secure the bracket to the selected site. 
Make sure that the mounting surface is strong enough to support the unit against shocks or 
vibrations that are likely to be encountered with the ship in motion. 
Compass Safe Distances ( in energized condition): 
  Receiver Cabinet alone:  0.60m ( standard),        0.40m ( steering) 
  Cabinet with Bracket:  0.80m ( standard),  0.45m ( steering) 
< WARNINGS > 
1.  DO NOT PLACE THE UNIT IN AN UNVENTILATED, SEALED ENCLOSURE, 
SUCH AS A THEFT–DETERRENT CABINET, OR OVERHEATING AND 
MALFUNCTION WILL RESULT. 
2. DAMAGE CAUSED BY EXPOSURE TO WATER SPRAY OR TO DIRECT 
SUNLIGHT WILL NOT BE COVERED BY THE MANUFACTURER’S WARRANTY.

long wire is to be used permanently, it should be insulated and at least five meters long. 
7.2.1.  Installation Site Requirements 
Active Antenna 
For best results and a prolonged service life, the active antenna unit should be installed: 
  at a site free from continuous, heavy shocks and vibrations, 
 away as much as possible from the feedpoint or radiating elements of HF/MF 
communications antennas, radar scanners and INMARSAT antennas, and 
  away as much as possible from, and above, any metallic obstructions. 
 < WARNING > 
LOCATING THE ACTIVE ANTENNA CLOSE TO THE FEED POINT OR RADIATING 
ELEMENTS OF AN HF/MF TRANSMITTING ANTENNA CAN DESTROY THE 
PREAMPLIFIER IN THE CYLINDRICAL HOUSING. 
Long Wire Antenna 
  A long wire antenna should be of insulated type and at least 5 meters long. Bare wire can 
short–circuit the antenna to ground and must not be used. 
  Before connecting the wire to the appropriate rear apron antenna connector, ask your 
dealer/qualified service engineer to change the internal wiring (two jumpers) on each 
receiver PCB in the cabinet and on the frequency converter board in the rear apron so 
that an input impedance match is achieved and that no DC voltage is present on the 
connector’s center conductor. 
 For best results, the wire should be raised as high as possible from the ground, and as 
much away as possible from nearby walls or surrounding structures as well as from the 
onboard devices listed above, or very poor, noisy reception will result. 
7.2.2.  Precautions for Cabling 
  To minimize the effect of interference from other onboard electronics, the coaxial cable 
from the antenna unit should not be run close to, and in parallel with, transmit antenna 
feed lines, radar waveguides, echo sounder transducer cables, control cables, power 
cables, etc. from such equipment. The same requirements apply to the routing of the 
long wire antenna. 
 If the cable is extended with coaxial connectors ( e.g. PL–258/PL–259 pairs), be sure to 
make the junctions waterproof using self–bonding tape or other appropriate sealant. 
< WARNING > 
THE CENTER CONDUCTOR OF THE COAXIAL CABLE IS AT +8 VDC (OR AT +12V 
WHEN WORKING ON 4209.5 KHZ) WITH THE EQUIPMENT SWITCHED ON. DO 
NOT SHORT THE CENTER CONDUCTOR TO GROUND OR DAMAGE TO THE 
POWER SUPPLY PCB CAN RESULT. 
 < CAUTION > 
Water intrusion into the coax cable will seriously degrade the reception performance.

  LSB = station A, bit 1 = station B,    bit 25 =   station Z,    bits 26 to 32 = reserved 
  To select a station, its corresponding bit should be set to “1.” To reject a station, its 
corresponding bit should be set to “ 0.” 
      For example, to select only stations E, J, M and T for storage, or output to the INS or printer 
port, set the transmitter ID masks as follows: 
00081210 hex 
 0 0 0 8 1 2 1 0 (hex)

8.  Summarized Theory of Operation 
8.1. What is NAVTEX? 
NAVTEX, a system of broadcast and automatic reception of global maritime safety 
information by means of direct display/printing telegraphy, is part of the *1GMDSS 
infrastructure, defined by *2IMO Assembly resolution A.706 (17). Broadcasting is 
accomplished by a worldwide network of dedicated coastal stations regularly sending 
weather information, navigational warnings, search–and–rescue (SAR) information and 
other related messages, all in an easy–to–read text format, to mariners free of charges. 
8.2. Operating Frequencies 
At present three frequencies are officially allocated by the *3ITU for NAVTEX broadcasting 
service: 518 kHz, 490 kHz and 4209.5 kHz. All *4SOLAS convention vessels are required to 
carry a receiver dedicated to receiving NAVTEX transmissions automatically on all the 
above frequencies. 
Transmissions on 518 kHz are in English and of general interest to vessels navigating 
international waters, while the 490 kHz service is primarily targeted at those working most 
of the time in areas close to transmitting stations, providing more localized information in 
national languages. Some stations also broadcast information to local users on 4209.5 kHz. 
Stations on each frequency transmit NAVTEX messages usually for a period of 10 minutes 
on a time–sharing basis to avoid cross–station interference. 
8.3. Service Area 
The coverage area of a 518 kHz station is normally 200 to 400 nautical miles in daytime 
hours, depending on the transmitting power level, and a signal travels along the surface. At 
night some of the signal often travels more than double the daytime coverage by being 
reflected a number of times between the surface and the ionosphere, a band of ionized 
atmospheric layers 50 to 400 km above the surface. The 490 kHz service area is less than the 
518 kHz coverage due to lower transmit power levels, but the nighttime coverage often 
extends greatly because of ionospheric reflections. The 4209.5 kHz broadcast, though 
catering mainly for inshore users and covering much less areas in the daytime, can be 
received from more than 1000 miles away during hours of darkness. 
8.4. Error Correction 
Signal propagation conditions constantly vary with time of the day and also with the season. 
The signal arriving at the receiver can be corrupted or distorted at any time by static 
discharges, natural noise, abnormal solar activity, unstable ionospheric conditions, 
interference between the signal coming directly from the transmitter and the one reflected 
from the ionosphere, etc. It is therefore likely that a vital NAVTEX message can be missed 
due to signal corruption or distortion at the receiving end. 
In order to ensure that each message is properly received within its intended area of 
coverage, a station sends out the same message twice, some hours apart, each with its  
identification code ( known as  B1 character), message type code ( B2 character) and a 
two–digit serial number (B3B4, ranging 00 to 99).    In addition, the system employs a mode 
of transmission called forward error correction (FEC), transmitting each alphanumeric 
character in the message twice at very short intervals. If the same character is received 
twice, the receiver considers it to be a true character. If either of the received characters is 
different or corrupted, the receiver treats it as an invalid letter, and displays or prints an 
asterisk (*) in its place, thereby securing the reliability of a received message.

8.5.  NAVTEX Receiver – General 
A NAVTEX receiver that complies with the relevant IMO resolutions and regulations for 
wheel mark certification is programmed to automatically receive and display/print a 
message, and avoids a repeated reception of the same message by checking the ID and 
numbering of each message. Using the ID and message type data attached to each 
message, the user can also program the receiver to reject certain transmissions and 
message types that are not of importance while in the current area, except for SAR and 
other urgent warning messages classified as type D messages. An audible and visual alarms 
are automatically triggered upon reception of such a message. To silence the alarm, the 
user must manually, or via an appropriate command from an INS terminal,    acknowledge 
the message arrival. Received messages are either printed on paper (for a receiver with a 
built–in printer) or displayed on a screen with memory for storage and retrieval (for a 
receiver with an integral LCD screen). 
8.6.  The AE–2000 NAVTEX Receiver 
The AE–2000 receiver has two built–in receiver, with the first receiver devoted to receiving 
518 kHz broadcast and the second receiver receiving either 490 kHz or 4209.5 kHz signal as 
selected by the user. Received messages are displayed across an 8–inch liquid crystal 
display (LCD) and stored permanently or temporarily as specified by the user. Up to 200 
messages, each with an average of 500 characters, received on the first and second 
receivers are separately stored and then automatically erased from memory 60 hours after 
the time of reception on a first–in–first–out basis. However, up to 25 messages can be 
protected against automatic erasure, and are stored in a separate area of the non–volatile 
message memory, in which case an additional 50 new messages can be stored in memory 
across each receiver screen. 
When a transmission occurs on the first and second receiver frequencies at the same time, 
the equipment receives both signals, displaying the first receiver message while storing the 
second receiver message in memory for later retrieval. An appropriate caution message 
shows up in the screen bottom prompt line to indicate the reception of a new NAVTEX 
message on the second receiver. 
Reception of a type–D message (SAR, piracy and armed robbery information) activates the 
audible and visual alarms. The received message text then is shown in red, making it easy 
to discriminate it from navigational (type–A) and weather (type–B) warnings. The audible 
alarm also sounds differently to indicate that a type–D message has been received. The 
alarm can be acknowledged remotely by an INS terminal connected to the RS–422 port on 
the rear panel. 
The stored messages can be output via three interface ports mounted on the rear panel for 
IBS/INS or other onboard applications The user can specify the ID, frequency and type of 
the messages you wish to output.  An optional printer can also be plugged in to print the 
current message in real time or those recalled from the non–volatile memory.

8.7. Operating Principle of AE–2000 
Figure 9–1 shows interconnections between the printed circuit boards (PCBs) comprising 
the AE–2000 system and interface connections from the PCBs to data input/output ports 
and peripheral devices. Figure 9–2 is the schematic of the antenna selector which allows 
selection of the desired antenna from a single keystroke on the keypad. 
To follow the circuit description below, see also the schematics of the receivers, CPU PCB 
and power PCB attached. 
Receiver Circuit 
To receive the three NAVTEX frequencies (518 kHz, 490 kHz and 4209.5 kHz), the system 
incorporates two independent receivers (first and second receivers) plus a frequency 
converter. The 518 kHz international broadcast is picked up by the first receiver (NT–2000A), 
and the 490 kHz national broadcast, by the second receiver (NT–2000B). The second 
national broadcast frequency of 4209.5 kHz is first converted down to 490 kHz by the 
frequency converter (N501–F/ C–A) and then fed to the second receiver. 
Each receiver is of straight amplifier type, consisting of two stages ( field–effect transistors 
V6 and V7) of amplification, followed by an IC amplifier (U1) and an amplitude limiter 
( diode pair V8 and V9 ). Located at the end of the amplification chain is an FM detector that 
consists of crystal–controlled oscillator B1, its associated parts and part of the IC circuitry), 
which demodulates a frequency–shifted (±85 Hz) RF NAVTEX signal into a stream of 
baseband DC pulses at 100 baud using a quadrature detection technique. The detected 
output is then fed to the CPU via opto–isolator K2. 
To test whether each receiver is functioning properly, a NAVTEX signal generator is provided 
on the PCB, consisting of quartz crystal B2, IC (N1) and their associated parts. When the 
self–diagnostic test function is activated via the menu, the CPU PCB supplies a test signal 
(modulating signal) to the generator via opto–isolator K4 and transistor switch V13, 
allowing the generator to produce a simulated frequency–shifted signal at the receiver 
frequency, and feeds it to the receiver input through relay K1. 
CPU Circuit 
The CPU PCB (N501–CPU–C) is built around a 16–bit single–chip microcomputer (U10) that 
has a CPU clocked at 24 MHz by crystal–controlled oscillator X1, and on–chip flash ROM for 
program software and on–chip RAM providing memory space for data processing of the 
demodulated signal. An external static RAM (SRAM) chip (U5, 512 kB) is mounted for 
message and ID storage, and is backed up by large capacity capacitor C6 (1.0 farad) for 
approx. 10 days in the event of continuous power–off. 
Another external SRAM (U1, 256 kB) is used to hold text for display on the LCD screen. U3 
and U4 are factory–programmed to jointly act as a display controller to perform various 
display control functions and text scrolling. The input/output interface between the CPU 
and externally connected devices consists of three external ports: U7 for the RS–232C port, 
U12 for the *RS–422 port and an opto–isolator for the I/O DATA port. 
*Input lines to the RS–422 port are insulated from ground by opto–isolators (ISO2, ISO3).

8.7.  Operating Principle of NT–2000/DEBEG 2902 ( continued –2 / 2 ) 
Power Supply Circuit 
The power supply PCB (N501–PWR–A/B) consists mainly of a switch–mode voltage 
regulator (U2) and a three–terminal voltage regulator (U1), supplying regulated DC outputs 
(3.3V, 5V, 12V) from an input voltage ranging 11 to 36 volts, though the nominal voltage is 24 
volts at which the performance specifications are fully met. Should the power line polarity 
be reversed accidentally, diode D1 will cause the fuse F1 (3A) to blow, thereby protecting 
the input circuit from possible damage. The regulated outputs from the power supply PCB 
are fed to the CPU PCB, through which the 12V output is also derived to operate the 
receivers and frequency converter. 
Another power supply board, termed the FL Inverter PCB (CXA–L0612A–VJL ), is also 
installed. This PCB is a DC–to–AC inverter unit, generating an AC voltage of approx. 1600V at 
approx. 60 Hz out of 12V supplied via the CPU PCB to power the fluorescent lamp used to 
backlight the LCD screen.
