    Custom cable lengths are available upon request. 2.2.11 Item No. 190-0650-01 AMRON WIRELESS TENDER HEADSET (Single Ear Muff) A single ear muff headset that is compatible with the 28B Wireless Tender option. Additional headsets can be ordered to allow other crew members, supervisors, crane operators, etc.
  • Page 12 To prevent this, the PANEL SPEAKER can be turned off using the SPEAKER SWITCH. Another option is to move the tender away from the communicator by using the Amron Model 2822-28 Walk-and-Talk Module accessory. This allows the tender to communicate while other members of the surface crew listen using the PANEL SPEAKER.
  • Page 13 If the tender requires more mobility at the dive site, the Amron Model 2821-28 Remote Push-to-Talk Module can be used to extend the headset cable. It includes a push-to-talk button on a clip- on belt module and comes standard with 25 feet (7.6 meters) of cable (custom...

    Acoustic feedback can also be avoided by moving the tender away from the communicator by using the Amron Model 2822-28 Remote Walk-and-Talk Module with 25-foot-long cable or the 28B Wireless Tender Option.

  • Page 27: Volume Controls Full Duplex (4-Wire)

    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. Amron NRF automatically captures the frequency spectrum of applied background noise within the audio frequency bandwidth and reduces it without affecting the diver’s speech.

  • Page 28: Inhalation Noise Reduction (Inr) Operation

    4.8.2 The Inhalation Noise Reduction feature has been fully integrated with both Amron’s portable and rack mount communicators. The built in INR module can recognize the inhalation noise through the use of high frequency content characteristics of inhalation noise.

  • Page 29: Active Noise Reduction (Anr) Operation

    ACTIVE NOISE REDUCTION (ANR) OPERATION 4.9.1 Not all noise cancellation headsets are the same. Amron’s new series of Active Noise Reduction (ANR) headsets isolates and reduces topside noise in very loud environments dramatically, allowing the tender and divers to communicate more clearly and comfortably with increased intelligibility.

  • Page 34 5.4.4 YEARLY CHECK For maximum service life, it is recommended that the diver communicator be sent back to Amron for a yearly check. 5.4.5 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 35: Troubleshooting

    2830A-XX SERIES THREE DIVER PORTABLE 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 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 follow the check-out procedures in sections 5.1 or 5.2.
  • Page 36 INDICATOR and test the battery if necessary. If the problem persists, disconnect the diver umbilical and perform the communicator check out procedure per section 5.1 or 5.2. If the communicator fails the check-out procedure, contact Amron for further assistance. If the communicator checks out, then the problem is likely in either the diver umbilical communication cable, the wiring of the diving hat/helmet, or the diver's microphone/earphone.
  • Page 37 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.
