All communicators will transfer topside noise to the diver when using the radio speaker only. To eliminate background noise and achieve clear communications, use a Push-to-Talk microphone, headset, or a Remote Walk-and-Talk with a headset.
2 and 3 Year Extended Warranties are available for this product. Please refer to the Attachments tab for further information on the warranty program.
The Amcom III Series 2830A has all of the same features of our Amcom II Series Communicators. These superior communicators utilize separate volume controls for each diver and the tender, both for the uplink and downlink paths.

Can you stack the banana plugs from the diver's communicators cable so you can have two divers on each diver channel?
Although it may be possible, we stronly discourage such operation. The added workload would cause overheating and stress to the amplifier card. Prolonged use in this condition will eventually cause perment damage and failure to the amplifier card.
Should I use a GFI when operating my radio off AC power?
When operating your Amron Diver Communicator on AC, it is critical to use a Ground Fault Circuit Interrupter (GFCI) or isolation transformer for tender and diver safety. Surges and spikes are common on AC lines found on ships, generated locally, or at the end of long extension cable runs and can exceed 1kVolt. Such surges and spikes can cause the fuses, F1 and F2, to blow on the battery charger board and in extreme cases damage the charger circuitry. The battery charger is designed so that such a failure will be isolated and will not cause a safety issue to the tender or divers. It is strongly advised that your Amron Diver Communicator be operated on an AC circuit with a high quality surge arrester or an AC isolation transformer.
When my battery does not appear to be holding a charge, how do I know if the problem is a bad battery or if the charger is broken?
To determine whether the problem is with the battery or charger you will need to verify if the charger is properly charging the battery.
Troubleshooting: Unplug your communicator and turn on the POWER switch. Measure the voltage across the yellow PUSH-TO-TALK (PTT) jack and write down this value for future reference. It should be greater than 9 Volts. Plug the communicator into an AC source and verify that the AC POWER LED on the front panel turns on. Re-measure the voltage across the PTT jack and note it down for future reference. It should be higher than the previous measurement. If this AC POWER LED does not light up when the communicator is plugged in, then check fuses F1 and F2 on the charger Printed Circuit Assembly (PCA). Allow the communicator to charge overnight. Unplug the communicator and re-measure the voltage across the PTT jack. If it is the same or less than the voltage you measured previously, then the charger is broken and the communicator needs to be sent in for repairs If it is the same or less than the voltage you measured previously, then the charger is broken and the communicator needs to be sent in for repairs. If the voltage higher than previous measurement but less than 13.5 Volts, then the battery is bad and needs to be replaced. If it is greater than 13.5 Volts but it still appears that the battery is not holding a charge, contact Amron for additional support. less than 13.5 Volts, then the battery is bad and needs to be replaced. If it is greater than 13.5 Volts but it still appears that the battery is not holding a charge, contact Amron for additional support.
How do I install a new microphone in my Amcom II Communicator?Please refer to the Panel Microphone Installation instructions located in the attachments tab.
Can my Amcom communicator work on 240V / 60Hz?Yes, the unit will operate on 240V 50/60Hz.
Can I operate my communicator while I’m charging the internal battery?Yes, however, the charger will charge the battery at a slower rate as some of the charger power is being used to operate the communicator. For the communicator only, units without options, about 20% of the charger’s power is being used by the communicator but units with HSU (Helium Speech Unscrambler) most of the battery charger energy is going to the communicator and HSU.
Why does the speaker on my communicator sound muffled?The issue is not with the communicator, it is with the wiring of the umbilical. There is always the potential for wiring the speakers and microphone out of phase, similar to wiring the speakers on a car stereo system. There is an orientation to the banana jacks and they should be wired for proper phasing with the communicator. A banana plug does have an identified ground side marked on the plug. Amron always sets up their umbilicals so that the ground side is located on the left side so the user can consistently plug in their umbilical and avoid phasing issues. If a banana plug is plugged upside down or is wired out of phase, the sound quality will be significantly reduced. If the phasing is out and the orientation of both plugs are the same, then the banana plug wiring should be reversed on “only one plug” to avoid this issue again. It does not matter which plug you choose to reverse the wiring on.
