Signal unit
From Halopedia, the Halo wiki
Signal units are small Covenant devices used for communication.[1] They are kept strapped to one's belt, and can be activated at the touch of a button.[citation needed]
The crew of the Rapid Conversion repeatedly used signal units to communicate with one another throughout the course of the First Battle of Harvest.[citation needed]
