
While diver is talking, tender adjusts this volume control to a comfortable
hearing level.
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.
