Set - to be placed in the apartment with which it is desired to communicate - comprising a Granular Carbon Transmitter, Watch Receiver, Cord, Automatic Switch, Buzzer, two No. 4 Dry Cells, and 12 yards of flexible Cord, with a 2-pin Connector, for the purpose of readily connecting the two instruments together.
This Set is complete in itself, and is intended for establishing immediate
communication between two rooms, etc.
If it is so desired, the Hand Combination can be replaced by another 'House' Set, thus enabling a call to be effected either way, by means of the buzzer, and a ringing key which is provided.
