These telephones require a power source for the transmitter.  Batteries were used and these would have been 3 volts and connected to MC (positive) and MZ (negative).

This phone cannot be connected to your normal exchange line as the bell will not ring and the transmitter requires batteries.

These phones were in use on the L.N.E.R Eastern Area in 1934.
