Avoidance of live transmissions is required to prevent unnecessary loading of the satellite channels. 5.2 Attention is drawn to paragraph 3 on the prevention of false distress alerts. 5 Self-test 5.1 Prior to carrying out any maintenance and, upon completion, a self-test should be performed, following the instructions on the equipment, and the results noted. It is recommended that the maintenance be performed at the time when the battery is to be changed. 2 Shore-based maintenance of all satellite EPIRBs, as defined in paragraph 1.2, should be carried out in accordance with these guidelines at intervals specified by the flag Administration and not exceeding 5 years. 4 Maintenance service interval 4.1 406 MHz satellite EPIRBs should be inspected and tested in accordance with MSC/Circ.1040. 3.4 If a distress signal is transmitted accidentally, the local RCC should be contacted immediately and informed of the coordinates of the test site. 3.3 Provision of a 121.5 MHz monitor receiver is required this will pick up the homing transmitter and give a warning if the EPIRB is accidentally activated outside the screened enclosure. ![]() 3.2 A radio-frequency-screened room or enclosure should be used for all maintenance procedures involving, or likely to involve, any transmission from an EPIRB. The transmissions may be picked up by aircraft as well as satellites. 3 Prevention of false distress alerts 3.1 Throughout the testing and maintenance process, great care must be taken to avoid the transmission of false distress alerts. 7 issue a shore-based maintenance report with a list of the test results and maintenance performed. 6 ensure that all personnel responsible for supervising and for carrying out the maintenance procedures are adequately trained and fully competent to perform their duties and. 5 keep records of maintenance, available for inspection by the Administration as may be required. #Shore based maintenance software#4 have access to up-to-date technical manuals, service bulletins and the latest software versions as provided by the original equipment manufacturer. 3 have access to batteries and other spare parts to the original equipment specification. 2 have access to adequate calibrated test equipment and facilities to carry out the SBM in accordance with these guidelines. 1 have a quality control system audited by a competent authority in respect of its servicing operation. 2 Shore-based maintenance (SBM) provider 2.1 The SBM provider should. #Shore based maintenance registration#1.3 The guidelines also apply to service exchange EPIRBs which should be properly encoded to match the appropriate registration database. EPIRBs may include 121.5 MHz transmitters, or Global Navigation Satellite System (GNSS) receivers. ![]() 1.2 The guidelines are intended to be applicable both to 406 MHz EPIRBs and to L-band EPIRBs, as either type may be carried to comply with the requirements of SOLAS regulation IV/7.1.6. GUIDELINES FOR SHORE-BASED MAINTENANCE OF SATELLITE EPIRBs MSC/Circ.1039 1 Introduction 1.1 The purpose of these guidelines is to establish standardized procedures and minimum levels of service for the testing and maintenance of satellite EPIRBs to ensure maximum reliability whilst minimizing the risk of false distress alerting. ![]()
