MANUAL OPERATION AND ACTIVATION
It is not recommended to operate the beacon inside a life raft or under a cover
or canopy. Do NOT tie the lanyard to the ship in distress, as this will prevent the
unit to functioning if the ship sinks.
1. Remove the locking pin from bracket cover
2. Remove the cover
3. Take out the EPIRB from the bracket
4. Break the seal and pull the locking pin holding the main activator switch
5. Push slider to move switch to ON position (the switch is spring-loaded and will
automatically go to the ON position)
6. Tie the beacon lanyard to you or to the survival craft
7. The strobe light, located at the top of the EPIRB, will start flashing indicating
that the EPIRB is operating
If possible keep the EPIRB in an open area, away from any metal objects (ship
construction etc.) that may limit the satellite coverage. Transmission can be
stopped by turning the switch to READY position and take it out of the water.

1 GENERAL DESCRIPTION
The Tron 40VDR is emergency equipment consisting of:
• Tron 40VDR Cospas-Sarsat emergency EPIRB.
• FB-40 - Automatic float free bracket.
• VDR storage module.
The Tron 40VDR EPIRB is developed to meet the regulations and rules for use
on vessels and life rafts in the maritime service. Tron 40VDR meets the following
specifications for 406 MHz EPIRBs for use in search and rescue operations at
sea.
See “Declaration of Conformity” document at www.Jotron.com for information
of required standards.
1.1 TRON 40VDR
The Tron 40VDR is buoyant and have water activated contacts which will start
DISTRESS transmission if deployed into water. Tron 40VDR are currently available with one float free bracket. The bracket prevents DISTRESS transmission if
water spray are applied to the EPIRB.
The Float free bracket, FB-40 is a covered bracket with an hydrostatic release
unit (HRU) which will release the Tron 40VDR if the bracket is submerged to a
depth of 2-4 meters if the ship are about to sink.
The purpose of the Tron 40VDR 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. 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 on the transmitters and on 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 of the
EPIRB.

1.2 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 28000 persons have been rescued by
the Cospas-Sarsat system (2009). Currently the system consists of 5 functional
satellites in a polar orbit constellation, these satellites cover the entire earth’s
surface and receive the emergency signal from the 406 MHz transmitter within
the Tron 40VDR, more polar orbiting satellites will be available in the future, giving a faster location and rescue time.
In addition several geostationary satellites are equipped with a 406 MHz transponder, these satellites are not able to locate the Tron 40VDR but will give an
early warning to the rescue forces, minimising 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 40VDR, is correct. It is also important that your EPIRB is registered in
the database for each country. This database is normally located in the same
country that the ship is registered.
1.2.1 SIGNAL DETECTION
When the Tron 40VDR is activated
(manually or automatically) it transmits on the frequencies 121.5 MHz and
406.037 MHz. An analogue signal is
emitted on 121.5 MHz and a digital
signal is transmitted on 406.037 MHz.
After the Tron 40VDR is activated, the
next passing satellite will detect the transmitted signal and relay it to an antenna at a ground station, called LUT.
The International Cospas-Sarsat System has ceased satellite processing of
121.5/243 MHz beacons from 1 February 2009.

1.2.2 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 Tron 40VDR 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. A second satellite pass confirms
the correct location (A). Doppler-only accuracy is within 5 km (3 mi) (3.1 statute
miles or 2.6 nautical miles)— that is, the position is sufficiently accurate for SAR
purposes even after only one pass. What’s more, the most likely of the two ’mirror’ positions can be determined valid with 98.5% accuracy after only one satellite pass. This accuracy can be increased to 99.3% using so-called ”combined
Leo-Geo processing,” and this technique also enables accurate positions to be
generated with as little as two or three bursts from the beacon (i.e. less than 4
minutes of transmission) and thus greatly increases the chances of being found
even if the beacon is ultimately consumed by fire or is otherwise destroyed
1.2.3 GPS ADVANTAGE
Tron 40VDR has been designed to operate with the Cospas-Sarsat system and
will enhance further the lifesaving capabilities of conventional beacons.
Please see picture on next page for comparison between Tron 40VDR and
EPIRB without GPS depending on detection by polar orbiting or geostationary
satellites.
GPS position is updated every 6-16 minutes, and can also be tested in SELFTEST.

1.2.4 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.
You should register your beacon with the national authority associated with the
country code in the hexadecimal identification (15 Hex ID) of your beacon. You
can register your beacon online with the Cospas-Sarsat IBRD if your country
does not provide a registration facility and your country has allowed direct registration in the IBRD: www.406registration.com
If your country operates a national beacon registry, consult the document
C/S S.007 ”Cospas-Sarsat Handbook of Beacon Regulations” available at
www.cospas-sarsat.org to obtain the point of contact.

USA REGISTRATION CARD
For registration of the beacon, use this link:
http://www.beaconregistration.noaa.gov
Follow instructions you see on your screen.
Other registrations methods are mail or fax. Forms are ready with correct information and it may be downloaded from the above web site.
The Emergency Contact information has to be accurate, especially regarding
the telephone number, as this will be used to validate an alert. Only if the beacon registration and approximate location details can be confirmed will USCG
(United States Coast Guard) launch an immediate rescue, otherwise there will be
a delay whilst further alerts from the same source are received and verified.
