apparatus, shall use that apparatus, or cause or permit it to be used, in contravention of the notice.
(5) Any person who contravenes the provisions of paragraph (4) shall be guilty of an offence and shall be liable on summary conviction— (a) where the apparatus with respect to which the notice was given was sealed or a part of it was removed under and in accordance with paragraph (2), for the first such offence under this sub-paragraph, to a fine of one thousand dollars and to imprisonment for three months, and, for any subsequent such offence under this sub-paragraph to a fins of two thousand dollars and to imprisonment for six months; and
(b) in any other case, for the first such offence under this sub- paragraph, to a fine of seven hundred and fifty dollars, and, for any subsequent such offence under this sub-paragraph, to
a fine of one thousand five hundred dollars:
Provided that no person shall be convicted of an offence under this paragraph if it is made to appear to the court that at the time of the use of the apparatus in contravention of the notice an application had been made in writing to the Authority for revocation of the notice and that the Authority had, without reasonable cause (the burden of proof whereof shall be upon the Authority), failed or neglected to revoke the notice within a reasonable time after receipt of the application for revocation.
6. Where a magistrate is satisfied by information on oath. ()that there is reasonable ground for believing that, on Bay specified premises or in any specified vessel, aircraft or vehicle, apparatus to which these regulations apply is to be found which does not comply with the requirement applicable to it under these regulations; and
(b) that it is necessary to enter those premises, or that vessel, air- craft or vehicle, and to examine or test any apparatus to which these regulations apply which may be found therein or thereon for the purpose of determining whether any such apparatus does or does not comply with the requiremeal applicable to it under these regulations; and
(c) that, within fourteen days before the date of the application to such magistrate, access to the premises, vessel, aircraft or vehicle for the purpose aforesaid has been demanded by, or permission to examine any such apparatus as aforesaid which has been found therein or thereon has been requested by, the Authority or any public officer authorized in writing in that behalf by the Authority and producing sufficient documentary evidence of his identity and, in the case of a public officer
I
authorized as aforesaid, of his authority, but in either case has been unreasonably refused,
| the magistrate may issue his warrant empowering the Authority or any | public officer or officers authorized in writing in that behalf by the Authority and named in such authorization to enter the premises or, as the case may be, the vessel, aircraft or vehicle and any premises on which it may be and to search the promises, vessel, aircraft or vehicle with a view to discovering whether any apparatus to which these regulations apply is situate thereon or therein, and, if he finds or they God any such apparatus thereon or therein, to examine and test it with a view to determine whether it does or does not comply with the requirement applicable to it under these regulations,
7. (1) The requirement referred to in regulations 3 and 4 is that Requirement. the apparatus shall be so designed, constructed, assembled and id- walled, and that such precautions shall be taken in relation to it (by means of the fitting of suppressors or otherwise), as to ensure...
(a) that the noise voltage at the electric supply line terminals of the apparatus when it is used at any frequency within the defined frequency range does not exceed the given number (if any) of microvolts for that frequency range:
Provided that this sub-paragraph shall not apply in respect of any apparatus that is designed for connexion at its terminals to a distribution system having a declared volt- age between conductors greater than 750 volts or a declared voltage between any one conductor and earth greater than 375 volts, and
(b) that the field-strength of the electro-magnetic energy radiated in any direction from the apparatus when it is used at any frequency within the defined frequency range does not exceed the given number (if any) of microvalts per metre for that frequency range at any distance of not less than the given distance for the same frequency range.
(2) (a) In paragraph (1), "the defined frequency range" means, in relation to any apparatus, the frequency range or, where there is more than one, any of the frequency ranges specified
in either the third or the sixth column of the Schedule for Schedule. the class and sub-division, if any, of the class (indicated in the first column of the Schedule) to which the apparatus belongs according as to whether the expression is used in respect of noise voltage at electric supply line terminals or in respect of field-strength of radiated electro-magnetic energy. (b) lo sub-paragraph (a) of paragraph (1) "the given number (if any) of microvolts" means, in relation to any apparatus
