1 GENERAL DESCRIPTION
The Main parts of the Capsule (Tron S-VDR CAPSULE) are the
EPIRB (EPIRB module) and the S-VDR Server module. The
Capsule is developed to meet the regulations and rules for use on
ships, vessels and life rafts in the maritime service. The Capsule
meets the following specifications for S-VDR and 406MHz EPIRB
for use in search and rescue operations at sea:
• IEC 61996 ed.2
• IEC 61097-2 ed2
• IEC 60945
• C/S T.001
• IMO MSC.163 (78)
• IMO A.810 (19)
• MED 96/98/EC
1.1 EPIRB MODULE
The Capsule is buoyant, and is designed to automatically release and to
automatically activate the EPIRB in case of an emergency where the
Capsule and its bracket is submerged into the sea. The EPIRB can also
be manually operated. One mounting bracket is available to mount it as
an automatic and manual EPIRB. The purpose of the EPIRB is to give
a primary alarm to the search and rescue authorities. The EPIRB gives
an immediate alarm when activated, transmitting the ID of the ship in
distress. The EPIRB will at the same time transmit the position of the
ship. Care must be taken not to activate the EPIRB unless in an
emergency situation, in such cases the user will be held responsible.
For periodic testing a test function is implemented. During the test
cycle the EPIRB does a self-test off the transmitters and the battery
status. No emergency signal is transmitted during the self-test. The
battery of the EPIRB will last for at least 168 hours from activation.
10 82310_UM_ SVDR_E
1.1.1 System description
The COSPAS/SARSAT system was introduced in 1982 as a
worldwide search and rescue system with the help of satellites
covering the earth’s surface. Since the introduction of the system
more than 11200 persons have been rescued by the
COSPAS/SARSAT system. Currently the system consists of 8
different satellites in a polar orbit Constellation. These satellites
cover the entire earth’s surface and receive the emergency signal
from the 406MHz transmitter within the EPIRB. In addition several
geostationary satellites are equipped with a 406MHz transponder.
These satellites are not able to locate the Capsule but will give an
early warning to the rescue forces, minimizing the time from an
emergency occurs till the rescue forces are at the site. Each
emergency EPIRB in the system is programmed with its own
unique code, therefore it is vital that the ships data that is given to
the dealer you obtained your Tron S-VDR CAPSULE, is correct. If
the EPIRB is programmed with serial protocol, it is important that
the EPIRB is registered in the database for each country. This
database is normally located in the same country that the ship is
registered.
1.1.2 Signal detection
When the EPIRB is activated (manually or automatically) it
transmits on the frequencies 121.5MHz and 406.028MHz.A
homing signal is emitted on 121.5MHz and a burst is transmitted
on 406.028MHz every 50 second after activation. This burst
contains all necessary information about the ships in distress. After
the EPIRB is activated, the next passing satellite will detect the
transmitted signal and relay it to an antenna at a ground station,
called a LUT (Local User Terminal). For the 121.5MHz signal the
satellite must be within line of sight of both the EPIRB and a
82310_UM_ SVDR_E 11
ground station. The ground station or LUT has a 2500 km satellite
reception radius centered at the LUT. In areas without LUT
coverage (mostly less populated areas in the southern hemisphere),
signals from the 121.5MHz transmitter will not be detected by the
satellites, only by passing aircraft’s. From the year 2006,no new
satellites will be launched including 121.5MHz receiver, and from
the year 2009,satellitedetection of the 121.5MHz EPIRB is
terminated. This is not the case with the 406MHz transmitter,
because the satellites have a memory unit, which stores the signals
for relay to the next available LUT giving it a truly global
coverage. Once the signal is received by the LUT, it is processed
for location and sent to a Mission Control Center (MCC).The MCC
sorts the alert data according to geographic search and rescue
regions and distributes the information to the appropriate Rescue
Co-ordination Center (RCC), or if outside the national search and
rescue area, to the appropriate MCC that covers the area that the
distress signal was detected. The RCC in turn takes the necessary
action to initiate search and rescue activities.
1.1.3 Distress location determination
The location of the distress signal is determined by taking
measurements of the doppler shift of the EPIRB frequency when
the satellite first approach and then pass the EPIRB. The actual
frequency is heard at the time of closest approach (TCA). Knowing
the position of the satellite and using the received doppler signal
information, it is possible to determine the location of the Capsule
from the satellite at the TCA. At the LUT, actually two positions
are calculated. One is the actual position (A) and the other is the
mirror image (B) position [FIG.1.1.3]. A second satellite pass
confirms the correct location (A).With the 406MHzsystem the real
solution can be determined on the first pass with a reliability of
nearly 90% and down to an accuracy of less than 5 km (3.1 miles).

1.1.4 Added value in the EPIRB
The EPIRB module has been designed to operate with the
COSPAS-SARSAT system and will enhance further the lifesaving
capabilities of conventional beacons. An integrated 12 channel GPS
module accepts continuous positional information from the
standard GPS system using 27 satellites providing an accuracy of
approximately 100m.Upon activation of the Capsule in an
emergency situation the positional information is incorporated into
the distress message transmitted to LUT.
The main advantage with integrated GPS in the EPIRB is the rapid
response and positional accuracy providing vital information during
a rescue operation practically eliminating valuable time spent
searching for the distressed. Whenever a distress message
transmitted by the EPIRB is detected by a polar orbit satellite
(LEOSAR) the delayed alert remains the same as for non-GPS
integrated EPIRB`s (max.90 min.), but the position accuracy is
improved considerably from a radius of 5 km. to amazing 100m.
Whenever a distress message transmitted by the EPIRB is detected
by geostationary satellite (GEOSAR) the alert is immediate (max.5
min.), still providing the accurate position of 100m. Please note
that the positional accuracy delay is depending on the actual
protocol used and programmed into the EPIRB and the location of
the emergency. The information is based on the capacity of the
LEOSAR/GEOSAR COSPAS-SARSAT system.
14 82310_UM_ SVDR_E
1.1.5 EPIRB registration
Normally the MCC will contact the vessel or the contact person
registered in a shipping register and/or an EPIRB register (Ships
owner, family member etc.) before alerting the RCC. This is to
determine if the alarm from the EPIRB for some reason is a false
alarm, and an expensive rescue operation can be avoided.
Because of this it is important that the ships data is correct in the
shipping register or in the EPIRB database. The Capsule purchased
in some countries will have a registration form attached to it, it is
important that this registration form is completed by the owner and
returned to the place the Capsule was purchased or to the address
specified on the registration form.
Other countries use the already available shipping register to obtain
the necessary information for a vessel in distress, in these countries
the ship is already registered and no registration form is necessary,
however it is vital that the coding of the EPIRB is kept up to date
with data on the ship (nationality, call.sign, etc.), to minimize the
time from an alarm to the start of the search and rescue operation.
Reprogramming the EPIRB can be done at authorized Jotron AS
agents in more than 250 different places throughout the world. If
you are a resident of the United States, you must register this
beacon with the National Oceanic and Atmospheric Administration
(NOAA) using the registration card included with the unit. Fill out
the form and send it to: SARSAT Beacon Registry, NOAA-
SARSAT, E/SP3, FB4, Room 3320, 5200 Auth Road, Suitland,
MD 20746-4304 Vessel owners shall advise NOAA in writing
upon change of vessel or EPIRB ownership. Transfer of EPIRB to
another vessel, or any other change in registration information,
NOAA will provide registrants with proof of registration and
change of registration postcards.

1.2 S-VDR SERVER MODULE
The S-VDR Server module consists of S-VDR Server module house
including Flashdisc. The S-VDR Server module is DC powered from
the ship via the bracket connector. The S-VDR data is fed from the
ships S-VDR system to the S-VDR Server module through the same
connector. When the Capsule leaves the automatic release bracket, all
electrically power and data connections between the ship S-VDR
system and the S-VDR Server module inside the capsule is broken.

3.1.2 S-VDR Server module
The S-VDR Server module consists of S-VDR Server module
house including Flash disc and a double-sided PCB board with
power regulator and PC circuits.
The S-VDR Server module is DC powered from the ship via the
bracket connector. The S-VDR data is fed from the ships S-VDR

20 82310_UM_ SVDR_E
3.1.3 EPIRB module
The EPIRB module consists of four printed circuit boards, which
are mounted in the upper housing:
1. The main board w/GPS patch antenna, Xenon flash and an
indicator LED
2. Antenna board. (121.5 / 406 MHz)
3. GPS interface board
4. GPS receiver
For automatic activation of the EPIRB module, put the capsule in
the upright position into the water, and the transmission starts when
the seawater completes the circuit between the two external
electrodes (sea water contacts).
When the capsule is mounted in the automatic release bracket
mechanism, there is a safety switch in the EPIRB module, a reed
contact activated by a magnet at the FBR-3 bracket, which disables
the seawater contacts. See figure 3.1.5.
If submerged in water, the hydrostatic release mechanism will
release the capsule at a depth of 2-4 meters. The transmission will
start when the circuit between the seawater contacts is closed and
the capsule is out of the bracket.
The EPIRB module may be manually activated with the main
switch, and is then independent of seawater contacts. The EPIRB
module will also operate while placed in the bracket when
manually activated.
The capsule may easily be released from the mounting bracket
manually.
82310_UM_ SVDR_E 21
3.1.4 Battery module
The Battery module is feeding the EPIRB module with 7.2VDC
power to keep the EPIRB transmitters active for 168 hours when
activated, and for test sequences.
The battery module consists of eight SAFT LSH20 Lithium-
Thionyl chloride (Li-SOCL2) batteries connected in series and
parallel and is attached inside the lower house.
3.1.5 Automatic release bracket, FBR-3
The FBR-3 bracket is the docking station for the capsule. A
connector and a cable connected to the ships 24VDC power and S-
VDR data keeps the S-VDR Server module alive and working
when the capsule is in the bracket.

4.2 Mounting the FBR-3
Bolt the unit to the vessel using the mounting holes.
The Float Free Bracket FBR-3 must be connected to the fixed
installation S-VDR installation
through the junction box according to the connection diagram in
paragraph 3.1.7.
When the Capsule is mounted in the FBR-3 release mechanism, it
operates as a float free automatic unit.
Therefore it is important that the bracket is mounted in a place
where there are no obstructions that can endanger the automatic
release of the beacon.
The location where the bracket is mounted should be as high as
possible on the vessel, protected from environmental conditions
such as direct sea spray, chemicals, oil, exhaust and vibrations. The
location must also be easily accessible for testing and maintenance.
4.3 Mounting of the Capsule into the FBR-3
Strain the spring loaded lower arm with the connector at the lower
part of the bracket.
Place the higher part of the Capsule into the top grip of the bracket
with the main switch facing out. Then push the Capsule into the
bracket and slowly release the lower arm, checking that the
connector pins at the bracket hits the connector holes at the
Capsule. Place the locking bolt into the corresponding holes in the
lower arm, and mount the clamp at the bolt.
82310_UM_ SVDR_E 27
4.4 Replacement and mounting of the Hydrostatic Release
Mechanism
The Hydrostatic Release Mechanism must be mounted before the
Capsule is placed into the FBR-3 bracket.
To replace the Hydrostatic Release Mechanism, remove the
Capsule from the bracket:
1. Remove the clamp on the locking bolt on the spring-loaded
lower arm.
2. Remove the locking bolt.
3. Whilst holding the Capsule, strain the spring-loaded lower arm
and gently remove the Capsule from the bracket.
4. Now the H20 unit is accessible. Unscrew the plastic bolt (3)
and remove the unit.
5. Replace the old unit with a new one and tag in expiration date
for 2 more years.
6. Screw the new plastic bolt on. Make sure the distance piece
(4,5,6) is in place on the plastic bolt. Tighten the bolt using hand-
force only until rubber seal (5) starts to compress.
Replace the Capsule into the bracket, reversing paragraph 1, 2 and
3.
28 82310_UM_ SVDR_E
4.5 Junction box
The junction box is connected to the connector on the FBR-3
bracket with a special cable.
All connections to the ships systems are done at the Junction box.
See figure 4.5.a.
The two fuses are for protection of + DC supply and Ground.
The fuses act as short circuit protection and will automatically reset
some minutes after the short circuit is removed.

82310_UM_ SVDR_E 31
5 OPERATING INSTRUCTIONS
5.1 FBR-3 Float Free Bracket
When the capsule is mounted in the FBR-3 bracket release
mechanism, it operates as a float free automatic unit.
5.2 Manual operation of EPIRB module
Figure5.2, EPIRB Main switch
The manual operation can be done when the capsule is mounted in
the bracket or when the capsule is removed from the bracket.
Break the seal on the main switch and pull the locking pin. Push in
the leftmost part of switch mechanism and the switch will
automatically go to the ON (Emergency) position.
The red indicator lamp and the Xenon flash on the main board will
start operating, indicating that the EPIRB module is active.
32 82310_UM_ SVDR_E
NOTE!
The EPIRB module performs a complete self-test before any
emergency signals are transmitted. The Transmitters will start after
approx. 70 seconds. At the same time GPS receiver is started. This
is done to prevent the GPS receiver to start in TEST position.
Turning the switch back to the READY position stops the
transmission. If the Capsule is out of the bracket, make sure the
battery compartment is dry to prevent activation of the seawater
contacts.
5.3 Automatic operation of EPIRB module
When the capsule is removed from the release mechanism and
placed into water it will automatically activate due to the seawater
contacts. Transmission will stop when the capsule is lifted out of
the water, and if necessary dried off.
When placed in the automatic release mechanism the seawater
contacts are disabled.
When the mechanism is reaching a depth of 2-4 meters, the capsule
will be released and transmission will start automatically.
Note! There is a time delay of approx. 10 seconds of
activation/deactivation with the seawater contact.
5.4 Testing the EPIRB module
To perform the self-test, the Capsule has to be removed from the
bracket.
82310_UM_ SVDR_E 33
WARNING
Releasing the Capsule from the bracket will interrupt all
connections between the ships S-VDR system and the FRM
inside the Capsule, and all recordings will be interrupted.
The regulations require the Capsule not to be removed for
more than 10 minutes.
1. Press the spring-loaded switch on top of the Capsule to the TEST
position, see paragraph 5.2. Keep hands and other objects away
from the upper part of the Capsule. (Away from the antenna).
2. A successful test will consist of a series of blinks on the LED
test-indicator, followed by a continuous light and a strobe flash
after app.15 seconds.
3. If the procedure fails to end up with a continuous light, this
indicates a fault in the EPIRB module. (See paragraph 6.2.1).
4. Release the switch and put the Capsule back into the bracket.
What the self-test actually does is first to wait app.15 seconds to
allow the reference oscillator inside the EPIRB module to warm up.
Then a short burst is transmitted by the 121.5MHz transmitter,
while the output level of the transmitter is checked. Finally, a test
signal is transmitted by the 406 transmitter. During this test signal
the battery voltage, output power and frequency is checked. While
testing the 406 MHz transmitter a test message is transmitted. This
test message is coded with a special synchronization code and will
not be detected by the COSPAS/SARSAT satellites. The purpose
of this test message is to control the actual coding of the EPIRB
module. This can be done with the Jotron AS test unit Tron
UNIDEC or another EPIRB tester.

5.5 Operation of the S-VDR module
5.5.1 Operating software
The software operating system of the S-VDR module is Linux. The
system includes SAMBA, which enables other software platforms
to access Linux file system, and a FTP (File Transfer Platform)
server.
For more detailed information, see the Technical manual.

5.6 Change of battery
5.6.1 MSC Circ. 1039
If the S-VDR Capsule is the main EPIRB on board the ship, the
rules of MSC CIRC 1039 apply, and the battery must be changed at
an authorized workshop.
If the S-VDR Capsule is the second EPIRB on board the ship,
authorized personnel can change the battery on board.
To change the battery, the lower Capsule Assembly is replaced
with a new one.
1. Remove the clips and the recovery ring around the equator ring.
2. Remove split pin and pull the U-shaped bolt from the
equator ring.

5.6.2 Battery disposal
Dispose in accordance with applicable regulations, which vary
from country to country.(In most countries, the thrashing of used
batteries is forbidden and the end-users are invited to dispose them
properly, eventually through non-profit organizations, mandated by
local governments or organized on a voluntary basis by
professionals).Lithium batteries should have their terminals
insulated prior to disposal.
5.6.2.1 Incineration
Incineration should never be performed by battery users but
eventually by trained professionals in authorized facilities with
proper gas and fumes treatment.

6 MAINTENANCE AND TROUBLESHOOTING
6.1 EPIRB module / battery module
The EPIRB should be tested and batteries replaced according to
MSC circ.1039. See chapter 5.6.1.
6.2 Testing EPIRB module
6.2.1 Self-test with sea water contacts activated
To perform the self-test with seawater contacts activated, the
capsule has to be removed from the release mechanism. Authorized
personnel should annually test the seawater contacts.
WARNING
Releasing the Capsule from the bracket will interrupt all
connections between the ships S-VDR system and the FRM
inside the Capsule, and all recordings will be interrupted.
The regulations require the Capsule not to be removed for
more than 10 minutes.
Remove the capsule from the release mechanism and go to paragraph
6.2.2.
6.2.2 Self-test with sea water contacts deactivated
Turn the switch to the «TEST» position. The red indicator will start
flashing for approx. 15 sec. This is to allow the internal TCXO
(Temperature Controlled Xtal Oscillator) to be stable.
Then the output power of both transmitters are checked, the battery
voltage and the PLL of the 406 Transmitter.
A complete message on the 406 Frequency is transmitted, with
inverted frame sync.
38 82310_UM_ SVDR_E
If all tests are passed there will be one flash in the Xenon bulb, and
the red indicator light will turn on and stay on until the switch is
released.
A successful test will then consist of a series of rapid flashes in the
test indicator, followed by one Xenon flash and continuous light in
the test indicator.
Any other behavior indicates a fault in the EPIRB module.
6.3 Maintenance of EPIRB
WARNING
Releasing the Capsule from the bracket will interrupt all
connections between the ships S-VDR system and the FRM
inside the Capsule, and all recordings will be interrupted.
The regulations require the Capsule not to be removed for
more than 10 minutes.
Every Month:
Perform EPIRB self-test. (See chapter 6.2.1).
What the self-test actually does is to send out a short test signal on
121,5 and 406,028Mhz,testing the output of the transmitter. While
transmitting the test signal, the battery voltage, output power and
phase lock is tested. During the test of the 406Mhz transmitter a
test message is transmitted, this test message is coded with a
special synchronization code and will not be recognized as real
alert by the COSPAS/SARSAT satellites. Carry out visual
inspection for defects on both the Capsule and Bracket. The
Capsule should be easily removed and replaced in the Bracket.
Make sure that the Capsule and Bracket is not painted or otherwise
covered with chemicals, oil, etc. Check the expiry date of the
82310_UM_ SVDR_E 39
EPIRB Battery and the Hydrostatic Release Mechanism. Check the
presence of a firmly attached lanyard in good condition and that it
is neatly stowed and is not tied to the vessel or the mounting
bracket. If the Tron S-VDR CAPSULE is the main EPIRB on
board, these rules must be followed: Every 12th Month: Perform
extended annual test according to IMO’s MSC/Circ.1040 (Annual
testing of 406 MHz satellite EPIRBs) as required by SOLAS
IV/15.9.This test can be carried out by one of Jotron AS authorized
representatives or any other service provider in possession of a
Tron UNIDEC, Tron DEC or any other Cospas/Sarsat EPIRB
tester/decoder.
The test ensures that the EPIRB is within its specifications and
complies with IMO and the COSPAS/SARSAT system.
Documented proof of test or Test Certificate containing test results
and EPIRB data issued by service provider must be kept onboard
for future inspections the next 12 months.
Every 2ndYear:
Hydrostatic Release Mechanism including Plastic Bolt on the Float
Free Brackets must be replaced.(Check expiry date on label).
Every 5thYear:
The EPIRB Battery must be replaced every 5th year, unless
otherwise instructed by the vessel flag state or local
authorities.(Check expiry date on label).

6.4 Test of GPS receiver without transmitters activated
This information is restricted and is included in the Technical
manual only.
6.5 S-VDR module
In accordance with SOLAS Chapter V Regulation 18.8; -the S-
VDR shall be subject to an annual performance checks. A ship
required under International rules to carry a functioning simplified
voyage data recorder (S-VDR), and under Paris Memorandum Port
State Control requirements a ship may be detained if the S-VDR is
not functioning properly.
The person carrying out the annual checks should be approved by
the ship’s Flag Administration and show evidence that he has been
authorized by the S-VDR manufacturer to service the particular
make and model of equipment. To act in accordance with the
requirements for bit-error-rate monitoring the status of the Tron S-
VDR flash disk memory is to be checked during the annual survey
to be specified by the S-VDR manufacturers procedures.
