| Here are two diagrams - you have to make up your mind which is the correct one
for your telephone. Under each diagram are instructions on how to wire the
telephone up for the UK Plug and Socket system. The telephone in the
upper diagram can be identified by only having 7 terminals in the main block,
whilst the lower diagram has two sets of terminal blocks of which the left hand
block is labelled "A Terminals". Diagram
