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

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 ( i nitially disabled)

Type–D messages (SA R , piracy and armed robbery 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 *1 software 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.

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.
*1 S TORED: 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.

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).

Int roduction
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.

Selecting and Re jecting Transm itters
4.8.1. Introduction
Initially the equipment is set to *1 display NAVTEX messages from all stations on the air
within the coverage area, *1 store those messages in memory and output them to the
printer port (RS–232C), *2 I/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. Set ting Procedure
To reject a specific station, execute the following step–by–step instructions:
(1) Highlight option “4: MAKE SEL / REJ SETTINGS” by pressing

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 *1 software
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).

TO SWITCH THE EQUIPMENT OFF AND UNPLUG THE POWER CORD BEFORE
OPENING THE CABINET FOR INSPECTION OR REPAIRS .
5.1.
Pow er–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
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.
The equipment cannot be turned on.
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.

User-Level Troubleshooting
The following description of the symptoms assumes that NAVTEX messages were properly
received for some time after initial installation time, and all message types and transmitter
IDs you wish to receive are selected ( via the steps in paragraphs 4.8 & 4. 9 ).
Symptom
Messages can be received in the
daytime, but with many error
characters ( ) at all times.
NAVTEX messages can be received but
with many error characters (asterisks)
and often cannot be stored.
Suggested Solution
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, NAVTEX signals can
travel distances in excess of 1000 nautical
miles depending on the season and
ionospheric conditions.
2. Run the self–diagnostic tests as per
paragraph 4.13, and check the receiver test
results. If the result for the receiver in
question
is
“ FAILED,”
ask
your
dealer/qualified service engineer to check
the related wiring harnesses to / f rom the
receiver PCB or replace the PCB.
3. Check if you have recently installed an
electronic device near the receiver cabinet
receiver or near the antenna. Turn off or
relocate such equipment away from the
NAVTEX receiver, and see if any
improvement can be obtained.
4. Unplug the antenna cable from the BNC
connector on the rear apron, and check the
voltage at the center conductor. It should be
8V+ on the ACTIVE ANT and 518 kHz
connectors, and 12V+ on the 490/ 4209.5
kHz connector. If no voltage is present or
the voltage is extremely low, ask your
dealer/qualified service engineer to check
the related connections to / from the power
supply PCB first and to replace the PCB, if
necessary.
5. Suspect that the preamplifier in the active
antenna unit is failing or water intruded into
the cable via the junction. Check by
replacing the amplifier unit and/or the cable.
If a correct replacement antenna is not
available, run at least 5 meters of insulated
wire from the center conductor of the

User–Le vel Maintena nce 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 Ser vice 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 Elec trical 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.

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.

Installation
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.

8.1.
Summarized Theory of Operation
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 *1 GMDSS
infrastructure, defined by *2 IMO 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 *3 ITU for NAVTEX broadcasting
service: 518 kHz, 490 kHz and 4209.5 kHz. All *4 SOLAS 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 a s B1 character), message type code ( B 2 character) and a
two–digit serial number ( B 3B 4 , 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.

NAVTE X 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–200 0 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.

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).

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.

(16) Message Scrolling:
Tag iNEW MESSAGEi is attached to message ID.
Indication “ STORED” is turned on at the end of each satisfactorily
received message together with a character error rate (CER=
XX%) readout
Live Messages :
Automatic, except for new type–D messages
Stored Messages :
Manual, line–by–line or page–by–page scrolling
(17) Message Storage:
Capacity :
200 messages ( average 500 characters per message) for each of 518
kHz, 490 kHz and 4209.5 kHz receivers. Up to an additional 50
messages can be stored (for each of 518 kHz and 490 kHz / 4209.5
kHz) if stored messages are protected.
Maximum storage of characters: 106,496 / frequency
Maximum characters/ message: More than 8000
If the equipment receives a message with a character error rate
33%, it will store the message but will receive
(CER) of > 4% and
the same message to be transmitted subsequently. If the
subsequent message has a lower CER, it will automatically replace
the previously stored one. If a message is received with a CER >
33%, it will not be stored.
Duration :
60 hours 20 minutes from successful reception of each message,
or until the storage limit is reached, after which old messages will
be automatically erased from memory on a first–in–first–out basis
except for user–protected messages that cannot be erased from
memory until their protection tags are removed manually. Time
source is derived from the CPU clock (24.00 MHz) to compute
message aging.
Storage without Power:
Protected messages are stored for at least 10 days after
power is removed continuously.

Specifications ( continued – 3 / 4 )
(18) Message Protection: Up to 50 messages can be protected on each receiver screen
against automatic erasure, and are saved in a separate area of the
non–volatile message memory. Protection of a user–selected
message can be cancelled to allow automatic erasure after a
60–hour time passage.
