Default Re: 706 Phone Conversion Help

There will be three wires coming from the on/off switch (as you say coloured brown, blue and slate - i.e. grey), which is a two-way switch. I don't remember off-hand which is which, but one will be the common, which will be connected to one on the "off" position and the other in the "on" position.

The use of this switch is entirely optional, but if you wish to use it to switch the ringer on and off (the purpose for which it would originally have been intended), you will need to connect the two wires that are connected in the "on" position in series with the ringer.

In a non-converted 'phone it is likely that the switch would have been wired in parallel with the ringer to short it out in the "off" position. Assuming this to be the case, remove both the orange wire from the ringer, and the slate wire from the switch from T16, and move the ringer wire to T13, along with one of the two switch wires identified above, and move the other wire identified above to T16.

The wiring will otherwise be the same as that given here.
