Line telephone sets with cordless handsets

1. Scope and Applicability

This PCR applies to a complete fixed-line cordless telephone configuration placed on the market as one set: a base station connected to a landline telecommunications network, one or more radio-linked cordless handsets, the rechargeable batteries installed or supplied for those handsets, and all power supplies, charging cradles, cables and accessories supplied as necessary for normal operation. It covers household, office and public-communication applications and analogue, VoIP or hybrid landline network interfaces when the product remains a cordless line telephone set.

The declared configuration shall identify the base-station and handset count, radio standard and actual operating frequency band for the intended market, network interface, power-supply and charging arrangement, battery chemistry, capacity, standardized physical size and end-user replaceability, display, keypad, printed circuit boards, housings, acoustic components, cables, accessories and packaging. Packaging is inside the life-cycle boundary but outside the reference product mass.

This PCR excludes cellular or satellite mobile phones, corded-only telephone sets, Wi-Fi-only handsets without a landline-connected base station, independent base stations, independent charging cradles, separately sold additional handsets, network routers and switching equipment, and component-only products. A product with cellular connectivity is not included merely because it can relay a cellular call through a cordless base.
