39 information on the intended use of frequency bands and on the most important radio-technical characteristics required of radio equipment using the frequency bands. Ficora shall re-examine regulations issued pursuant to subsection 1, if it is possible to assign additional frequencies for the activity subject to a licence referred to in section 95(3) or if a telecommunications operator or other party representing frequency band user groups presents a justifiable request for re-examination. When issuing regulations on the use of frequencies suitable for the provision of electronic communications services, Ficora shall comply with technology and service neutrality. Ficora may, in the regulation referred to in subsection 1, derogate from: 1) technology neutrality of network and communications services if this is necessary to: a) avoid harmful interference; b) protect public health against electromagnetic fields; c) ensure technical quality of the service, common use of radio frequencies or the fulfilment of general interest objectives; and 2) service neutrality, if this is necessary to: a) ensure the safety of human life; b) promote social, regional or geographical cohesion; c) avoid inefficient use of frequencies; and d) promote cultural and linguistic diversity as well as media pluralism. When preparing the regulations referred to in subsection 1, Ficora must work in cooperation with the Ministry of Transport and Communications. If a regulation concerning use of an individual frequency band could have a significant effect on the general development of the communications market, the frequency Ficora plan for the frequency band in question will require confirmation by a Government Decree issued pursuant to section 95(1). In order to promote common use of radio frequencies, provided there is justifiable cause, Ficora may also permit other radio communications than those which accord with the purpose of use for a radio frequency band assigned by a Government Decree pursuant to section 95(1) or by a regulation as referred to in subsection 1 if these other radio communications would not restrict use of the frequency band for its primary purposes nor cause interference in the radio communications appropriate to the primary purposes. Section 97 Special regulations regarding spectrum administration This Act applies to radio equipment on board Finnish vessels and aircraft and in any Finnish equipment sent into space, even when this equipment is not within Finnish territory. Ficora issues regulations on the radio frequencies that can be used by electrical appliances, other than radio equipment, that are designed to generate radio waves and are used for scientific, industrial, medical or other corresponding purposes, as well as the conditions that must be observed in the use of such appliances. Ficora issues regulations concerning the construction and use of amateur radio stations as well as other regulations to be followed in the amateur service concerning the frequencies to be used, transmission powers, spurious emissions, addressing of transmissions and unidirectional transmissions. A radio licence whose granting provisions are laid down in section 40, a radio frequency reservation referred to in section 44, a proficiency certificate referred to in section 265, a certificate endorsement referred to in section 266, and a decision concerning a call sign of a radio station by virtue of section 304(1)(5) may be signed using a digital signature.
