Ericsson followed the trend to produce modern thermoplastic telephones in 1962 with the Dialog. Their 1947 bakelite phone was looking rather old fashioned. The new Dialog, following the UK 700 type and the US 500 type was, if anything, even more modern in design. It featured a very lightweight handset (250g), printed circuit board, line regulator and adjustable bell. It retained however the traditional Ericsson front number label and side cord entry. Some examples of this phone would have been used in Britain on ‘Swedish Ericsson’ PABXs.
