CHAPTER 1. REGISTRATION OF INFORMATION
1.1 Necessity of Registration
The users of 406MHz beacons need to fill out the registration card containing vessel name,
Identification Data and Nationality and register the equipment to the government and the service
company. If you use unregistered equipment in the emergency situation, the search and rescue
operation cannot be done immediately owing to nothing information about ships in distress. The
SEP-500 GPS EPIRB will be delivered to the customers after saving all information for the users.
1.2 RadioStationLicense
An EPIRB is a radio transmitter and must therefore be added to your radio license.
If you have been allocated a radio callsign, then you already have a radio license for your VHF
or MF radio set. You should update your license to include your EPIRB.
For further details see your license or use these contact numbers.

CHAPTER 2. FALSE ALARMS
2.1 Prevention of False Alarms
The EPIRB operates under the following situations.
zIf the main unit is in the sea, its sea switch operates and it transmits a distress signal.
zIn case [ON] switch on top of the equipment is pressed, it transmits a distress signal.
Please be aware of the following to prevent the wrong distress signal TX.
zStay the equipment away 1meter from magnetic objects (speaker, compass etc.).
zDo not clean the equipment with water.
zStore it in a case with the sticker on the front side.
zDo not take out the wet equipment from the case.
zDo not store it in water.
zIn case no stopping by the button, put it in the case with the front sticker on the face. The
whole function is stopped by compulsion so that it cannot be transmitted.

2.2 ReportingofFalseAlarms
Should there be, for any reason, an inadvertent activation or false alarm, it must be reported to
the nearest search and rescue authorities. The information that should be reported includes the
EPIRB 15-digit Unique Identifier Number (UIN), date, time, duration and cause of activation, as

When COSPAS-SARSAT satellite receives a distress signal, the signal transmits to the MCC
(Mission Control Center) via the LUT(Local Users Terminal). The MCC delivers the distress
signal to the nearest RCC(Rescue Coordination Center) and the RCC performs Search and
Rescue operations. The SEP-500 receives the GPS information and it transmits more accurate
distress position than the EPIRB without the GPS so that it makes to perform prompt search &
rescue operations.
