More Information
	This item number has been replaced by 2830A-16 NEWLY DESIGNED ENHANCEMENTS: • High Audio Fidelity Ultra-low noise circuit combined with noise suppression circuitry produces crystal clear speech. Automatic gain adjustment will guard audio signal from distortion, enhance speaker protection and audio quality. Increases band width 47%. • Extended Battery Operation Time Audio amplifier card deploys the state-of-the-art Class-D digital audio power amplifier. Has very low power dissipation, produces less heat, and extends battery life up to 32%. • Flexible Gain Settings The audio amplifier card has adjustable gain settings to accommodate different communication applications and environments. • Ultra-Low Electromagnetic Interference (EMI) EMI is achieved through spread-spectrum and de-phase control techniques providing for optimum integration with diving systems. FEATURES: The wireless tender master transceiver is conveniently installed in the option panel of this portable communicator allowing the tender to communicate to divers with hands-free operation and no required buttons to push. The transmitter/receiver unit is housed in a rugged plastic casing that can be clipped to a belt or slipped into a pocket. A single charge of the NiCad battery from the included AC adapter is capable of operating (transmitting and receiving) continually for up to 5 hours. In standby mode, battery will last for up to 8 hours. Diver umbilical connections on the front panel are 5-pin MS (Military Standard) connections. Separate channels and volume controls for each diver and tender to accommodate individual earphone and microphone adjustments, equipment variations and individual comfort levels. Divers’ umbilicals can be set to 4-wire mode (full duplex) or 2-wire mode (push-to-talk) or any combination of the two modes for any diver. Ability to use both dynamic and pre-amplified diver microphones with a unique circuit that detects microphone type and automatically adjusts volume levels. Weatherproof push-to-talk microphone for better voice intelligibility topside. For optimum clarity, see Tech Note (below) for other recommended equipment. Internal charger allows for simultaneous charging and operation of the unit while protecting the rechargeable battery from being over-charged. Automatically supplies power to the audio amplifier when AC power is disconnected to allow for continued operation.

To eliminate background noise at the surface, use the 2829-11 Wireless Tender Kit or the 2405-28 Push-to-Talk Microphone, included with this model. As an option, the 2401-28 Deluxe Headset with Boom Mic can be purchased for optimum communications along with the 2822-28 Remote Walk-and-Talk (4-wire mode) or the 2821-28 Remote Walk-and-Talk (2-wire mode) for tethered tender mobility, when the wireless tender module is not being used.

Information

This item number has been replaced by 2830A-16

The AMCOM™ III 2830A-06 Three-Diver Deluxe Portable Communicator with Wireless Tender and MS Connections includes a built-in 4-wire full duplex wireless tender module that allows the tender to be in constant communications with all three divers while having hands-free mobility to attend to other matters. The Wireless Tender option operates on 2.4 GHz with range up to 120 yards (110 meters). Multiple Wireless Tender Kits can be used together as "listen only" devices, as only one remote headset on the system has priority to listen AND talk to the divers. This design allows the capability to add an unlimited number of remote listen only wireless headsets for other topside personnel such as dive supervisors and crane operators. Note: Depending on the age of the unit, existing non-wireless communicators in the field can be sent back for retrofitting a Wireless Tender transceiver in the option panel.

This deluxe communicator includes three 5-pin MS (Military Standard) umbilical connections on the front panel and features separate channels and volume controls for up to three divers and the tender so that uplink and downlink paths can be customized for varying equipment configurations and individual comfort levels.

The newest version of the AMCOM™ III has the same versatile user-interface, rugged durability and great sound quality as its predecessor with several new digital enhancements: (1) High-Audio Fidelity; (2) Extended Battery Operation; (3) Flexible Gain Settings and (4) Ultra-Low Electromagnetic Interference (EMI). The Overview tab outlines the many outstanding features that continue to make this model the most popular and powerful communicator on the market today.

FAQ's

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.

Can my Amcom communicator work on 240V / 60Hz?

Yes, the unit has an operating range of 90-264 VAC, 50-60 Hz..

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 charging circuitry, you will need to verify if the battery is being charged.

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 the AC POWER LED does not light up when the communicator is plugged in, then check fuse located on the amplifier card.
Allow the communicator to charge overnight.
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.

What are the environmental parameters that Amron's comms units can be used in?

Temperature: Class C Ambient Temperatures –25°C to +55°C Humidity: Class A Relative humidity up to 96% at all relevant temperatures, no condensation Vibration: Class A On bulkheads, beams, deck, bridge EMC: Class B All locations including bridge and open deck
