    LED will start blinking at a rate of about once per second. When the battery reaches its end-of-charge, the LED will turn off and the 2810E will go into shutdown mode to prevent damaging the communicator or rechargeable battery. It is advised that the 2810E with rechargeable battery be connected to the charger as soon as possible once the BATTERY CONDITION INDICATOR starts blinking.
  • Page 12 PANEL SPEAKER and the microphone if the tender is near the 2810E. To prevent this, the PANEL SPEAKER can be turned off using the SPEAKER SWITCH. Another option is to move the tender away from the 2810E by using the Amron Model 2822-28 Walk-and-Talk Module accessory.

  • Page 13: Diver Connections

    If both are used at the same time, the PANEL SPEAKER is active as a microphone. This allows a crew member to talk to the diver using the PANEL SPEAKER even if the tender is away from the 2810E using the Remote Push-to- Talk Module in 2-Wire mode.

  • Page 22 SPEAKER SWITCH should be turned off to prevent acoustic feedback. Acoustic feedback can also be avoided by moving the tender away from the 2810E by using the Amron Model 2822-28 Remote Walk-and-Talk Module.

  • Page 24: Maintenance And Troubleshooting

    The following are a series of step-by-step procedures to perform a functional check of your 2810E communicator using only a headset. These steps check all communication functions of the 2810E 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 setup.
  • Page 25 If that does not resolve the problem, then go to the troubleshooting section to determine the cause. 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.

    The battery voltage can be measured independently using a Voltmeter by measuring the voltage across the EXTERNAL BATTERY JACK. The voltage has to be 9 Volts or greater for the 2810E with rechargeable battery to operate. It is recommended that the 2810E be recharged for at least 10 hours if the measured voltage is less than 12 Volts (depending on the age of the battery and the surrounding temperature).
  • Page 28 MODEL 2810E USER MANUAL The voltage has to be greater than 6.5 Volts for the 2810E-1 with alkaline batteries to operate. It is recommended that the battery be replaced if the voltage is below 10 Volts. Before replacing either battery, the battery connections should be checked by opening the battery compartment and inspecting the wires.

Alternatively, the PANEL SPEAKER can be turned off using the SPEAKER SWITCH located on the front panel.

  • Page 33: 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.
