Product FAQ's

Ask a Question

  • 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.

  • 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 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.

  • 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.

  • Can two batteries be charged at the same time if I run a splitter inline?

    Yes, but it will take twice as long to charge the batteries.

  • How can I test for a blown fuse on my Amcom II series communicator?

    If the unit is plugged into a live outlet and turning on the switch does not cause the AC POWER LED to light up, then the fuse(s) are probably blown. Unplug the unit from the outlet, remove the fuses and check continuity with a multimeter. Replace any fuse that does not show continuity.

  • 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.

  • 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.


    1. Unplug your communicator and turn on the POWER switch. 
    2. 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. 
    3. Plug the communicator into an AC source and verify that the AC POWER LED on the front panel turns on. 
    4. Re-measure the voltage across the PTT jack and note it down for future reference. It should be higher than the previous measurement. 
    5. If the 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). 
    6. Allow the communicator to charge overnight. 
    7. Unplug the communicator and re-measure the voltage across the PTT jack. 
      1. 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
      2. If the voltage higher than previous measurement but less than 13.5 Volts, then the battery is bad and needs to be replaced. 
      3. 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.
