4.4.2 RECORDER OUTPUT - This is a single RCA Phono jack (color-coded black) that
provides a transformer isolated of both the diver and tender communications. It is
designed to drive the standard line-level inputs of audio or video recorders with
input impedances as low as 600 Ohms. The RECORDER OUTPUT will not record
the signal from the AUXILIARY AUDIO INPUT.
4.4.3 AUXILIARY AUDIO INPUT - This is a set of two RCA Phone jacks (color-coded
red and white) that provides a means to connect an external audio signal for diver
entertainment. Although this input will accept a stereo audio source, it will be
converted into a monaural signal before going to the diver. This signal is not heard
in either the tender headset or via the PANEL SPEAKER. The earphone output of
most MP3 players can be connected to this input using an adaptor cable like the
Amron Audio Adaptor Cable (Amron Part Number 180-1000-00). This feature will
only work if the diver is wired in Full Duplex (4-Wire) mode.
There is no separate volume control provided for the diver entertainment signal.
The audio device provides the volume control. It is advised at the start of diving
operation, and before the external audio device is turned on, that the tender adjust
and verify the TENDER TO DIVER VOLUME level is correct and comfortable for
the diver. Then starting with the lowest volume, adjust the volume on external
device until a comfortable level is achieved. If the tender is connected in the Full
Duplex (4-Wire) mode, the volume level should not be so loud as to prevent the
diver from hearing the tender. If the tender is connected in the 2-Wire mode, then
the entertainment will be cut off whenever the PUSH-TO-TALK BUTTON or PUSH-
TO-TALK JACK is used. The PUSH-TO-TALK BUTTON can be used by the tender
to cut off the entertainment even if the tender is connected in the Full Duplex (4-
Wire) mode.
WARNING!
The EXTERNAL BATTERY input can be used to recharge the 2810E rechargeable sealed lead acid battery. It is
strongly advised to use the provided Amron External Charger, Model 2823-603, to charge or operate the
communicator. This charger has been designed with the necessary electrical isolation to prevent dangerous
currents from the AC lines from reaching the diver.
If you use an external power supply, the maximum voltage needs to be limited to 15 Volts if the rechargeable
battery is in the unit. If a higher voltage is to be used, it is advised that the battery be disconnected or removed
from the communicator to prevent possible damage to the battery.
