EPIBB 406.028 MHz # 2
Country Code: 211 ON-AIR TEST MODE
Standard Location Protocol
MID: 123456 Beacon no: 0
N 53 deg 30' +4'32 E 10 deg 00' -6'40
Internal Navigation Device, 121.5MHz Homing B112 = 1/Yes
Programmed Message (Bit 25-144): 8D321E240035814786AB779206A979
Programmed Identifier (Bit 26-85): 1A643C48006B028
Freq:406,028.8 kHz Level: 222
The level figure is only an indication of the signal strength – not an exact measurement. The
purpose of this figure is to ensure a reliable test. A level figure of 140 or more is advisable.
Bit 26-85 (15 Hexadecimal), Bit 25-112 (22 Hexadecimal) and Bit 25-144 (30 Hexadecimal)
can be decoded by using the decode program made available by Cospas-Sarsat on the website
www.cospas-sarsat.org
Please note that it may not be possible to make 121.5 MHz frequency measurements of all
EPIRBs, as the AM modulation in some cases will prevent this. If so, select AF instead of Frq.
In the AF mode the internal loudspeaker is switched on and the AM modulated signal can be
heard during transmission. This proves that the EPIRB is transmitting on the correct frequency.
AIS-SARTs and MOB Devices
When performing AIS-SART and MOB tests, always use the test mode on the beacon. Doing
so, the beacon will radiate an AIS message of type 14 with the text "AIS TEST" along with three
AIS messages of type 1 containing the beacon's actual position and other AIS data. By
receiving these two message types the test box confirms that the AIS SART is working all right.
If the beacon is accidentally activated in the emergency transmission mode, it will radiate the
text "AIS ACTIVE". This will alert nearby ships and coast stations. Then, the device should be
turned off at once and the false alert reported to the nearest coast guard station or Search and
.
Rescue centre
Use this setup:
1) Select the AIS-SARTs test mode and press OK.
2) Set number.
As you may wish to test several beacons in a row, each AIS-SART can be given its own
individual set number for recognition. Default number is 1. Press OK to confirm, or press ↑ or ↓
to change to another number. Then, press OK and go to the test.
