Rack Mount 4-channel Round Robin Communications System

Image Gallery


The design of the C-Phone 4R Diver Communications System incorporates 4 channels which are typically used for two working divers, one standby diver and an auxiliary channel, making underwater communication simpler than ever. Each channel, including the tenders, has its own individual audio record output to allow end users to easily identify communications during playback. 2 tender inputs allows the capability for the Dive Supervisor to add an additional tender, such as a Client Representative or Crane Operator for direct communication with the divers. The C-Phone 4R has a simplified user interface which allows easy activation/de-activation of diver to diver and operates in both 2 wire and 4 wire (round robin) modes.
