FAQ's

Why does the speaker on my communicator sound muffled?

The simplest way to fix this issue is to unplug the red banana plug from the red microphone 5-way binding post on the communicator and rotate it 180 degrees then reinstall it. This should fix your problem. For a more detailed explanation of what happened, please read below. 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.

Can you stack the banana plugs from the diver's communicator cable so you can have two divers on each diver channel?

Although it may be possible, we strongly discourage such operation. The added workload would cause overheating and stress to the amplifier card. Prolonged use in this condition will eventually cause permanent damage and failure to the amplifier card.

What type of cable do I need to connect my Amron communicator to my Outland video system?

Amron communicators and Outland Technology’s video systems have a RCA Phono Jack. To connect the two systems together, you will need an audio cable with RCA Plugs on each end.

How do I install a new microphone in my Amcom II or III Communicator?

Please refer to the Panel Microphone Installation instructions located in the attachments tab.

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 fuse to blow on the amplifier card assembly. The power supply 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.

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.
