OTHER DIVER CONTROLS (4-WIRE MODE)
If conditions change as a group, the tender volume controls can be used as master volume
control.
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 d
ivers 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.
Or you can disconnect his microphone circuit, which will disable his microphone.

WIRELESS TENDER OPTION /28A
This option is installed in the right hand area of the Diver Communicator front panel. Amron’s
Full Duplex (Full Duplex™) Wireless Tender is designed to allow the top
-side tender to
communicate to divers with hands-free operation. This allows the tender to check equipment
and perform other tasks while still maintaining constant contact with the divers. This option
can also be used in the two wire mode to listen to the diver-tender communications.
The Wireless Tender Option operates on one of forty frequency channels. This allows
multiple systems to operate in close proximity without interfering with each other. There is a
master transceiver located inside the diver communicator. The channel is selected by setting
a set of eight dip switches (located under the battery). Both the remote and master
transceivers have to have the same dip switch setting. The factory default setting is
1,1,1,1,0,0,0,1 (1 is ON). In order to change the channel of operation; it is required to apply
changes to both units (master and remote). Amron recommends that the channel be changed
by a trained technician.
Additional 2829-11 Wireless Headset and Transceiver Kits can be purchased for use with the
AMCOM
as standby “listen only” devices. Only one transceiver ca
n be used to talk and listen
to the divers at a time but any number of transceivers can be used in listen-only mode. The
