This equipment has been specially designed to work in connection with private automatic exchanges, and is primarily for use in an executive's office so that communications may be carried on without engaging either hand, which is necessary when using an ordinary telephone instrument.

Reception is by means of a loudspeaking receiver and transmission by means of a sensitive microphone. Should, however, privacy of reception be desired, the loudspeaker can be cut off and the Bakelite micro-telephone used.

The polished wood case contains an amplifier suitable for 200-250 volts a.c. supply, a microphone, a loudspeaking receiver and a call buzzer. Switches are provided for connecting power to the amplifier and for cutting off the loudspeaker.

Direct calling on 5, 10 or 20 lines by means of lever keys, can be arranged by the addition of a plinth, as illustrated, and extra keys can be incorporated to provide secretarial, preference or silence facilities, the last-named enabling all incoming calls to be suppressed when the executive wishes to be undisturbed.

When ordering, the facilities required, the number of direct lines and the exchange voltage (24v or 50v) should be stated.
