INSTRUCTIONS FOR KEEPING THE RADIO LOG AND THE RADIO OPERATORS
OBLIGATION ACCORDING TO NATIONAL AND INTERNATIONAL REGULATION.
1. The radio log shall be kept in accordance with requirements in the Radio Regulations, SOLAS Convention, national
regulations regarding radio installations and the STCW Convention (STCW 95 including the STCW Code) including the
relevant regulation regarding watch keeping on board
passenger and cargo ships.
2. Unauthorized transmissions and incidents of harmful interference should, if possible, be identified, recorded in the
radio log and brought to the attention of the Administration in compliance with the Radio Regulations, together with an
appropriate extract from the radio log. (STCW Code B-VIII/2 No.32)
TEST OF RADIO EQUIPMENT AND RESERVE SOURCE OF ENERGY
Weekly:
GMDSS handheld VHF transceivers to be tested without using the mandatory required emergency batteries.
Monthly:
Float-free and manual EPIRBs to be checked using the means provided for testing on the equipment. Check data for
periodical maintenance requirement for float-free EPIRB search and rescue radar transponders (SART) to be checked
against 9 GHz radar.
False alerts transmitted by EPIRB
False alerts are a serious problem for the rescue service. Nearly 90% of EPIRB initiated distress alerts turn out to
be false alarms.
