The telephone needs to be restrapped as follows:
Telephone is wired as follows. The standard diagrams are (N806, N810, N841 & N846).
The bell or ringing device should be 4000 ohms resistance. This can be rectified by either fitting the correct ringer or by inserting a 3.3K resistor in series with the ringer. The telephone should already be fitted with a Rectifier No. 205. If one is not fitted then it is recommended that one is fitted.
