Electromagnetic compatibility and Radio spectrum Matters (ERM); Maritime Personal Homing Beacon intended for use on the frequency 121,5 MHz for search and rescue purposes only; Part 1: Technical characteristics and methods of measurement

Scope

The present document lays down the minimum requirements for maritime "Personal Homing Radio Beacon for 121,5 MHz
search and rescue purposes", and incorporates the relevant provisions of the International Telecommunication Union (ITU)
radio regulations.
Operational radio beacons described in the present document are intended only for transmission of radio signals on the
frequency 121,5 MHz for locating purposes.
Beacons for training purposes will be frequency programmed in accordance with national licensing. It should be noted
that licensing for such use is also dependent on the administration responsible for the waters where the equipment is
operated and not the registered flag state.
The present document applies to radio beacons intended for short-range maritime personal homing applications. For this
application, both the radiated power and the length of time of operation are reduced to enable the equipment to be
sufficiently small and light to be worn comfortably at all times.
