6. The voice is amplified by the upper electronics module and routed through the ComRope Connected to the ComRope at the diver s end is the earphone microphone assembly typically an EMA 2 for the Interspiro FFM The tender s speech is reproduced by the earphone part of the EM cable When the diver speaks his voice is picked up by the mask micro phone located inside the mask being used The voice is routed through the ComRope received by the upper electronic module amplified and then routed to the tender s headset If a second diver is on line he will hear and talk as well in the same manner The volume of the tender and diver s is controlled by separate volume controls on the outside of the upper electronics module IMPORTANT SAFETY NOTES It is extremely important that the divers are dressed out in a manner that will strain relieve the ComRope Commercial dive schools typically instruct students to have the ComRope tethered to the diver s harness or buoyancy compensator with a quick release If someone pulls on the ComRope and the diver loses control of the ComRope the pull is on the harness not on the diver s mask This setup prevents accidental removal of the diver s mask 3 Additionally the divers should be dressed out to allow a quick disconnect from the ComRope to allow for a situation where a diver must free himself from the ComRope In the event divers and the surface tender lose voice communications both shou
