"Unapproved Equipment
It is an offence to use, import, manufacture, sell, advertise or possess, without authorisation, non-approved cordless telephones. Use of such apparatus,
particularly high power models that are available in some other countries, can cause harmful interference to other authorised radio users. It is also an offence to connect them to the public telephone system.
Where necessary, the Agency will prosecute or take other enforcement action under the Wireless Telegraphy Acts to prevent the harmful interference caused by those who use non-approved apparatus or possess such apparatus without authority to do so. Agency officials can seize apparatus found in unlawful use or possession and the courts can order its forfeiture.
Importation: Travellers intending to purchase cordless telephones abroad for use in this country should beware. Such telephones are unlikely to meet the relevant performance specification or be approved for connection to the public telephone system in the UK. They are liable to be seized and forfeited by Customs and Excise and their use may not only cause harmful interference but may also be illegal. Even possession may be an offence."
