TELEPHONE No. 724L

This telephone was used on subscriber push button VF signalling systems. There is provision for one press button switch to be fitted.

It was produced from a Telephone No. 706 but modified as follows:-

• A push button keyset replaces the dial.
• The dial aperture in the cover is enlarged to cater for the keyset.
• The oscillators are located on a special mounting above the terminal strip.
• Two special brackets are fitted to take a Buzzer No. 32A and a Capacitor.

Introduced around 1963 and available only in Grey.
