Fitting RotaTone to a GPO 332
Below shows a RotaTone converted GPO 332.
Note A – Rectifier no. 205 – should already be fitted, email us if you require one.
Note B – 3.3k resistor – should be fitted (if required), if not there will be a strap/link. A 3.3kΩ REN should be fitted if your telephone has 2 x 500Ω bell coils. If there are 2 x 2000Ω bell coils, only a strap/link is required.
