Section 55

Any person who establishes, installs, maintains, provides or operates a radio‑communication system or service or any radio‑communication equipment in any place or on board any vessel, aircraft or in any vehicle in Singapore without a licence granted under section 5 or any regulations made under this Act shall be guilty of an offence.

Any person who is in possession of any radio‑communication equipment is deemed, until the contrary is proved, to have operated the same.

The occupier of any dwelling house or premises in which is installed any radio‑communication equipment in respect of which a licence is not in force shall be guilty of an offence.

It is a defence in any proceedings for an offence under subsection (3) that the occupier was not aware and could not with reasonable diligence have become aware of the existence in the dwelling-house or premises of the radio‑communication equipment.[35
