2830R THREE DIVER COMMUNICATOR USER MANUAL
2830R-UM
REV 5.0
21
Connect d
iver 1’s
umbilical to the Diver 1 input. Repeat for diver 2.
Connect tender headset earphones to Headset (input), and headset microphone to Tender
Microphone (input). Turn speaker off to avoid acoustic feedback. Operation with speaker is
possible by extending tender's headset away from the speaker. Use Amron Model 2822-28
headset extension cable (25 foot).
Operating the PTT (push-to-talk) switch will establish a priority channel for communication.
PTT cuts out the diver’s microphone and prevents divers from talking.
This allows an important conversation to be carried on without interruption, or the ability to
establish a clear channel of communication.
NOTE
: When operating with a standby diver who does not have his hat/helmet on, acoustic
feedback may occur. This can be avoided by turning his volume down Diver to Tender, which
cuts off his microphone, yet will enable him to monitor the diver/tender conversation.

5.7.4
Push-To-Talk Jacks (Yellow)
Connection for remote control of the push-to-talk function: plug the hand held
microphone yellow banana plug into this jack. Operation of the hand held
microphone is simple and straight forward, hold the microphone in your hand, place
the microphone within one half inch of your mouth, depress lever on side of
microphone and speak clearly and distinctly into the microphone.
The communicator has an automatic speaker disconnect relay which disconnects
the front panel speaker when using the hand held microphone. This greatly
reduces the background noise during transmissions to the divers. This feature is
also functional when using an AMRON headset, and headset extender (Model
2821-28).
