opportunity to express itself in this regard or to rectify its violation within one month of the date of such notification, or within a shorter period if the undertaking agrees or PTA prescribes in the case of a repeated violation, or within a longer period if PTA agrees to such. Should an electronic communications undertaking fail to cease its violation within the prescribed time limit, PTA shall take appropriate measures. In this connection, PTA may apply daily fines, cf. Article 74. The electronic communications undertaking shall be notified of PTA's decision, together with the grounds for it, and allow it a reasonable length of time to comply with the decision. In addition to the authorisations in the second and third paragraph, PTA may apply daily fines to an electronic communications undertaking which fails to provide the information it is obliged to deliver within a reasonable period determined by PTA. In the case of serious or repeated violations of the requirements for a general authorisation or conditions connected to rights or special obligations, if measures to ensure compliance with the law have failed, PTA may suspend an electronic communications undertaking's network operations or service or revoke its rights temporarily or permanently. PTA may, if there is evidence of violation of the requirements for general authorisations or conditions connected to rights or special obligations which result in immediate danger to public health or safety, or could create serious financial or operating difficulties for other electronic communications undertakings or users of electronic communications networks or services, take provisional decision to improve the situation prior to taking a final decision. The electronic communications undertaking concerned shall, following a provisional decision, be granted an opportunity to express its opinions and suggest improvements. If appropriate, PTA may confirm its provisional decision. Article 74 Penalties Violations of this Act and Regulations issued by virtue thereof shall be liable to fines or imprisonment of up to six months in the case of serious or repeated violations. Violations due to negligence shall only be liable to fines. Violations of Chapter IX of the Act, on Protection of personal data and privacy, shall be liable to punishment as prescribed in the first paragraph. If such a violation is carried out for material advantage, whether of the individual concerned or others, such may be punished by imprisonment of up to three years. Electronic communications equipment, which has been operated without authorisation, may be confiscated, cf. Article 69 of the Criminal Code, as subsequently amended. When an electronic communications undertaking does not comply with legal provisions, the requirements for general authorisation, conditions for special rights or individual decisions of PTA, the Administration may decide, in accordance with the provisions of Article 73,to cancel the undertaking's registration, revoke its rights, add further conditions or apply daily fines amounting from ISK 50,000 to 500,000 to ensure compliance with its instructions. 32/34
