This equipment consists of a single unit containing transmitting and receiving components and includes a charging panel, batteries and headphones.

It can be used for distress (SOS) signalling or for emergency CW communications by means of the telegraph hand key on the front panel. It uses a conventional long-wire type of antenna.
