    Amron’s advanced NOISE REDUCTION FILTER (NRF) incorporates a complex DSP algorithm which filters out background noise while allowing the diver’s speech to be clear and intelligible.

  • Page 28: Maintenance And Troubleshooting

    The following are a series of step-by-step procedures to perform a functional check of your 2830R/24 series communicator using only a headset. These steps check all communication functions in both 2-Wire and Full Duplex (4-Wire) mode. If the communicator checks out using these procedures, then any communication problems are probably located somewhere else in the system.

  • Page 29: General Maintenance

    If that does not resolve the problem, then go to the troubleshooting section to determine the cause. 4. Identify the microphone and headset leads. When using an Amron headset, the microphone is the red banana plug and the headset is the black banana plug.

  • Page 30: Recommended Maintenance Schedule

    6.3.4 Yearly Check For maximum service life, it is recommended that the diver communicator be sent back to Amron for a yearly check. 6.3.5 Long Term Storage If the diver communicator is to be stored for a period greater than 30 days, it is recommended that it be stored in a cool dry location.

  • Page 31: Troubleshooting

    2830R THREE DIVER COMMUNICATOR USER MANUAL Troubleshooting Most problems are usually simple issues that can often be found by careful inspection of the diver communicator, diving umbilical, and diver helmet wiring. The following section will describe the troubleshooting procedure for several common issues. If these sections do not cover your particular issue, it is recommended that the diving umbilical be disconnected from the diver communicator and the check-out procedures in section 6.1 be conducted.
  • Page 32 If the fuse is open, replace with the same type: 3.15 Amp, 250V, Fast Acting. Close the lid; re-install the screws and re- test the communicator. If the communicator still appears dead, contact Amron per section 3.2 for further assistance.
  • Page 33 If this does not solve the problem and the umbilical cannot be immediately replaced, then operate in 2-Wire mode until a replacement umbilical can be used. Amron strongly recommends the use of the Amron CC1 communication cable. It has been specially designed for clear communications and long service life.

  • Page 35: Full Duplex (4-Wire) - What, Why And How

    2830R THREE DIVER COMMUNICATOR USER MANUAL FULL DUPLEX (4-WIRE) - WHAT, WHY AND HOW Amron has designed the AMCOM Full Duplex (4-WIRE) mode from the ground up, taking advantage of state-of-the-art electronics technology to provide a superior hard wire communication experience.

  • Page 36: What Is Full Duplex (4-Wire)

    On the surface, a tender using a headset may get some acoustic feedback via the PANEL SPEAKER. The solution is to put some distance between the tender and the PANEL SPEAKER by using the Amron Model 2822-28 Walk-and-Talk Module accessory. Alternatively, the PANEL SPEAKER can be turned off using the SPEAKER SWITCH located on the front panel.

  • Page 37: Why Full Duplex (4-Wire)

    Amron Diver Communicator uses an independent microphone amplifier for each diver circuit as well as for the tender. This allows Amron Diver Communicators to use the power of common-mode rejection to cancel any coupled noise for each microphone as well as providing less loading of the microphone than in 2-Wire mode.
  • Page 38 To revert back to 2-Wire mode, simply remove black banana plug from DIVER EARPHONE (black) jack and plug it on top of DIVER MICROPHONE (red) plug. Things to keep in mind when using Amron's AMCOM diver communicators: With the AMCOM diver communicators you can mix 2-Wire and Full Duplex (4-Wire) modes of operation.
