Wall telephone instruments for LB systems

With the exception of the magneto the instruments comprises chiefly the same parts as a normal wall instrument for CB or automatic systems; this allows for using the instrument with but slight modifications when changing over to another system. The generator is of a new type having small dimensions but giving great output.
The transformer has a closed iron core of sheet alloy and is anti-sidetone connected, which in combination with the good properties of the handset ensures considerably better transmission qualities than those of earlier instruments of similar kind.
Normally the instrument is connected so that its own bell does not ring when calls are sent out, but the connection can easily be modified on the terminal block of the instrument in order to make the bell ring.
Each instrument requires two dry cells RK 210. A suitable battery case is RK 2300.
