Description and Installation

The Answering Set No. 3A is capable of automatically answering an unattended telephone with an announcement previously recorded by the customer. This is an answering only machine and differs from an Answering and Recording Set which will also record a message from the caller.

The Answering Set No. 3A measures 19.5 cm (width) x 30.5 cm (depth) x 6.0 cm (height) and weighs 1.5 kg. It is supplied with a separate mains transformer which is wired to the answering set. A cord connected to the answering set and terminated with a Plug No. 420. A hand microphone complete with a cord and a proprietary supplied multi-connexion plug.

The set is wired to receive automatic ringing only and is internally connected in a high impedance mode, and is therefore connected across the line. For this reason it cannot be used for the following:-

Shared Service

1 Answering Set No. 3A
1 Plugs for Socket-Outlet No 103 (Fused at 3 amps)
