|MAGNETO, GENERAL SERVICE (1000)
The need for a magneto telephone of contemporary styling is met by this instrument which has been designed solely for magneto working and is suitable for lines of up to 1000 ohms loop resistance. It replaces Type N2121A and is made in the colours listed below.
The shapely, lift-off case is a one-piece moulding with a ribbed front and no dial aperture.
The handset is ideally shaped for comfort in use and maximum transmission efficiency. It has an inset transmitter and an inset receiver with rocking armature. Cradle switch plungers and springsets operate in a practically frictionless movement.
The internal apparatus comprises a rotating-magnet generator, anti-side-tone induction coil with closed-iron circuit, 1000 ohm ringer, a capacitor for the induction coil circuit, and the cradle switch springs. These are all fixed to the metal base plate, which has rubber feet and is secured to the case by captive screws.
The telephone has perforations under the ringer gongs and ventilation cups on each side of the case near the handset giving free circulation of air.
Line wires terminate at screw connections in a rectangular moulded terminal block connected to the telephone by a 4 way close-braided cord which enters the instrument via a rubber protector.
Cord conductors and all connecting wires are insulated with p.v.c.
Cells for transmitter battery are not supplied unless ordered.
