Star Trek Original Series Classic Communicator

This is the first generation of subspace communication devices. The Communicator's compact and lightweight design along with its powerful range of 1200 kilometers made this communication device standard issue to all officers in Starfleet. This classic model was used for ground-to-orbit and global audio contact. Once aboard a Starship, the main computer handled all intership communications. Though this communicator was obsolete by the 24th century standards, its simple design allowed for easy field maintenance and modifications. Of particular note are the manual dials which controlled emergency signals and frequence response of the communicator. These manual overrides were later replaced by an internal sub-matrix processor.
