Export versions may have an 'Emitron' brand badge. Provision is made for push-button pre-selection of three MW radio stations in addition to manual tuning. The receiver is comprised of two units, a control unit and a combined Amplifier/Power Unit Type A for 12 volts (the Type B is for 6 volts). High Tension power supply is provided by a non synchronous vibrator. The units are finished in black crystalline enamel with chrome plated bezel and knob trims on the control unit, or to car manufacturer's specification.
