The case is built up from pressed steel, finished with a pleasing and durable black enamel, relieved by nickel-plated metal fittings and incorporating a convenient writing desk.

A separate receiver and transmitter, hanging micro-telephone or micro-telephone resting on a cradle, as desired.

The generators will operate a 1000 ohm ringer satisfactorily through a line resistance up to 30,000 ohms.

Polarised ringers-for resistance see table below.

The transmitter arm on N2800 type is adjustable for height.

The terminals are enclosed, mounted on ebonite, and all parts of the circuit are very efficiently insulated from the case.

A lightning arrester is fitted.
The battery compartment will accommodate 2 dry cells each having maximum dimensions up to 2.25 x 2.25 x 6.5 inches.
