How to wire a Trimphone with a standard BT style lead

Items you will need to complete this:-

A Trimphone (obviously!)
A flat bladed screwdriver
Tweezers or pointy nose pliers
3.3K Ohm 1/4Watt resistor (there may be one aready in the phone)

The first thing you need to do is remove the cover. If you lift the handset you'll see a single white nylon screw where the earpiece rests. Remove this screw. The body will then lift off the base. You may have to wiggle it over the dial. Once the cover is removed you should see a board that looks similar to this (probably including and the dust and fluff!)
You can see 2 rows of screw connectors.
T1 - T9 are on the inner row with T1 towards the rear of the phone
T10 to T19 are on the outer row with T10 towards the rear
You'll probably need the tweezers or pointy pliers to remove the links

Remove link T6 - T7
Remove link T4 - T5
Insert link T5 - T6
Connect red wire of line cord to T8
Connect blue wire of line cord to T6
Insert links T16 - T17 - T18 - T19
Connect white wire of line cord to T18
Connect green wire of line cord to T15
Insert a 3.3K resistor between T4 - T5

Make sure all wires are neatly tucked up out of the way
Replace the cover and nylon screw
Plug you phone into a BT style socket (make sure you have a phone/internet splitter)
If you have a mobile phone (who hasn't these days) try ringing your mobile
Assuming that conversation went well (I have my best conversations when I'm talking to myself on the phone) hang up and ring your home number from your mobile. Make sure the ringer volume control on the Trimphone isn't turned off first, and you should hear your Trimphone warble away merrily :-)
