IMPORTANT NOTE :
1) Before replacing the handset make note of the wires to each terminal on the existing unit (an easy way
is to cut each core off leaving a piece of the insulation in place with colour visible) twist unused cores
together (so you know they are not used, do not short them out).
2) Some older systems will have cable with one coloured core and a solid white core in this case mark
each core with a marker or tape.
3) Some systems may have loop on wiring, you w
ill have 2 cables into your handset (make sure any joins
remain, as these may be serving other flats on the system).
