to a fine at level 2 on the first occasion on which the person is convicted of the offence; and
to a fine at level 3 on each subsequent occasion on which the person is convicted of the offence.
If the person acts as an agent for another person in carrying out an act mentioned in paragraph (3), that other person is liable under paragraph (5) as if that other person had personally carried out the act.
The requirement referred to in regulation 7 shall be complied with in the case of every apparatus to which these regulations apply, whether manufactured, assembled, installed, imported, purchased, hired or otherwise obtained before or after the day on which these regulations are published in the Gazette, if such apparatus is to be used in Hong Kong: (L.N. 256 of 1994)
Provided that in the case of an apparatus belonging to the class specified in regulation 2(1)(a) or (ab), the use of the apparatus shall be deemed to comply with the said requirement if the person using the apparatus establishes— (L.N. 72 of 2014)
that suppressors were fitted to the apparatus by the manufacturer, assembler or importer of— (L.N. 72 of 2014)
the apparatus; or
if the apparatus belongs to the class specified in regulation 2(1)(a), the boat or vehicle concerned; and
that the suppressors so fitted remained fitted to the apparatus at the time of use, or that suppressors having the same electrical characteristics had been correctly fitted to the apparatus at that time in substitution for those fitted as aforesaid, and in either case that the suppressors were then in good electrical and mechanical repair and condition; and

or that any components that had been substituted for those components had the same electrical characteristics and had been correctly fitted.
Save as provided in paragraph (3) and in regulation 9, it shall not be unlawful for any person to use any apparatus to which these regulations apply by reason only that it does not comply with the requirement referred to in regulation 7, but the non-compliance therewith shall be a ground for the giving of a notice under regulation 5.
Any person who uses an apparatus belonging to the class specified in regulation 2(1)(a) or (ab) that does not comply with the requirement referred to in regulation 7 shall be guilty of an offence and shall be liable on summary conviction, in the case of the first such offence, to a fine at level 1 and, in the case of any subsequent such offence, to a fine at level 2. (L.N. 153 of 1993; L.N. 256 of 1994; E.R. 1 of 2013)
If the Authority is of the opinion—
that any apparatus to which regulation 4 applies does not comply with the requirement referred to in regulation 7; and either
that the use of the apparatus is likely to cause undue interference with the working of any apparatus for telecommunications used for the purpose of any safety of life service or for any purpose on which the safety of any person or of any vessel, aircraft or vehicle may depend; or (36 of 2000 s. 28)
that the use of the apparatus is likely to cause undue interference with the working of any other apparatus for telecommunications and in fact has caused or is causing such interference in a case where the Authority considers that all reasonable steps to minimize interference have been taken in relation to the station or apparatus receiving the telecommunications, (L.N. 72 of 2014)
the Authority may serve on the person in possession of the apparatus a notice in writing requiring that, after a date fixed by the notice, not being less than 14 days from the date of service of the notice, the apparatus is not to be used, whether by the person given the notice or any other person, or, if the Authority thinks fit so to frame the notice, the apparatus may only be used in such manner, at such time and in such circumstances as may be specified in the notice: (L.N. 72 of 2014)
Provided that if the Authority is satisfied that the use of the apparatus concerned is likely to cause undue interference such as is referred to in sub-paragraph (b), the date fixed by the notice may, in the discretion of the Authority, be the date of service of the notice or any other date earlier than 14 days from the date of service. (E.R. 1 of 2019)
If the Authority is satisfied that the use of any apparatus to which regulation 4 applies is likely to cause undue interference such as is referred to in paragraph (1)(b) and that the circumstances of the case warrant the service of a notice under that paragraph requiring that the apparatus shall not be used from the date of service of the notice, it may, in addition to the service of such a notice and either before or after the service of the notice, seal the apparatus in such manner, or remove such part thereof, as ensures that the apparatus is not used, but in such a case, where the apparatus is sealed or a part thereof is removed before the service of the notice, the notice aforesaid shall be served within 3 days after the apparatus is sealed or the part removed therefrom. (E.R. 1 of 2019)
A notice under paragraph (1) may be revoked or varied by a subsequent notice in writing by the Authority served on the person in whose possession the apparatus then is:Provided that—(a)where a notice under this paragraph has the effect of imposing any additional restrictions on the use of the apparatus, the provisions of paragraph (1) relating to the coming into force of notices shall apply in relation to the notice as if it had been a notice served under that paragraph; and(b)where the Authority is satisfied that the apparatus has been altered or otherwise made to comply with the requirement referred to in regulation 7, it shall revoke the notice and forthwith break the seal (if any) on, or replace the part (if any) removed from, the apparatus.
No person, being a person who knows that a notice of the Authority under this regulation is in force with respect to any apparatus, shall use that apparatus, or cause or permit it to be used, in contravention of the notice.
Any person who contravenes the provisions of paragraph (4) shall be guilty of an offence and shall be liable on summary conviction—
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 at level 3 and to imprisonment for 3 months, and, for any subsequent such offence under this sub-paragraph to a fine at level 4 and to imprisonment for 6 months; and (L.N. 256 of 1994)
in any other case, for the first such offence under this sub-paragraph, to a fine at level 2, and, for any subsequent such offence under this sub-paragraph, to a fine at level 3: (L.N. 256 of 1994)
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.
Where a magistrate is satisfied by information on oath—
that there is reasonable ground for believing that, on any 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
that it is necessary to enter those premises, or that vessel, aircraft 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 requirement applicable to it under these regulations; and
that, within 14 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 identity and, in the case of a public officer authorized as aforesaid, of the officer’s authority, but in either case has been unreasonably refused, (E.R. 1 of 2019)
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 premises, vessel, aircraft or vehicle with a view to discovering whether any apparatus to which these regulations apply is situate thereon or therein, and, if the Authority, public officer or officers find 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.
The requirement referred to in regulations 3, 3A and 4 is that the apparatus must be designed, constructed, assembled and installed, and precautions must be taken in relation to it (by fitting suppressors or otherwise), so as to ensure that when the apparatus is used—
for an apparatus belonging to the class specified in regulation 2(1)(a)—the interference of the boat or vehicle concerned complies with at least one of the standards or regulations specified in Part 1 of Schedule 1; or
for any other apparatus—its interference complies with at least one of the standards or regulations applicable to the apparatus as specified in Schedule 1. (L.N. 72 of 2014)
(Repealed L.N. 72 of 2014)
The requirement in paragraph (1) shall be deemed to be complied with for the purposes of regulations 3 and 4, in the case of a sale, offer or advertisement for sale, letting on hire, offer or advertisement for letting on hire or use of electrical lighting and similar equipment, if the person selling, offering or advertising for sale, letting on hire, offering or advertising for letting on hire or using, as the case may be, the apparatus, establishes— (L.N. 72 of 2014)
that suppressors were fitted to the apparatus by the manufacturer, assembler or importer;
that the suppressors so fitted remained fitted to the apparatus at the time of the sale, letting on hire, offer or advertisement for letting on hire or use, as the case may be, or that suppressors having the same electrical characteristics had been correctly fitted to the apparatus at that time in substitution for those fitted as aforesaid, and in either case that the suppressors were then in good electrical and mechanical repair and condition; and
that the apparatus at the time of the sale, offer or advertisement for sale, letting on hire, offer or advertisement for letting on hire or use, as the case may be, consisted of the same components as those which were fitted at the time when the apparatus was manufactured or assembled, or that any components which had been substituted for those components had the same electrical characteristics and had been correctly fitted. (L.N. 153 of 1993)
(Repealed L.N. 72 of 2014)
During the transitional period, the requirement referred to in regulation 7 is to be regarded as having been complied with in respect of a continuously regulated apparatus in the circumstances specified in paragraph (2).
The circumstances are that the apparatus is designed, constructed, assembled and installed, and precautions are taken in relation to it (by fitting suppressors or otherwise), so as to ensure that when the apparatus is used, at any defined frequency or at any frequency within the defined frequency range—

The limit increases linearly with the logarithm of the frequency.
If the average limit is met when using a quasi-peak detector receiver, the test unit is deemed to meet both limits, and measurement with the average detector receiver need not be carried out.
The power of any heating device is to be excluded.
The limits for continuous conducted interference specified in paragraph 1 of this Part, as increased by the following amount, apply—
44 dB (for N[9] < 0.2);
20 log1030/N dB (for 0.2 ≦ N ≦ 30);
0 dB (for N > 30).
N is the click[10] rate determined from the formula N = n/T, T being 120 minutes or the observation time in minutes, whichever is less to produce 40 clicks, and n being the number of clicks registered during the observation time.
A click is defined as a disturbance which—
exceeds the maximum limit[11] specified in paragraph 1 of this Part;
lasts not more than 200 ms; and
is separated from a subsequent disturbance by at least 200 ms.
The apparatus under test is deemed to comply with the maximum limit if not more than a quarter of the number of clicks registered during the observation time exceed the limit.
