    MODEL 2810E-2001 USER MANUAL CONTROLS AND CONNECTIONS Before using the 2810E-2001 chamber communicator, the operator should be familiar with all the controls and connections. While reading this manual, you will find capitalized words such as PANEL SPEAKER. These words are to remind the reader that additional information can be found in this section of the manual.

It is advised that the 2810E-2001 be connected to an AC outlet as soon as possible once the BATTERY CONDITION INDICATOR starts blinking. While there should be enough time to safely complete a normal diving operation, the exact amount of time is dependent on the age and condition of the sealed lead acid battery.
  • Page 13 If both are used at the same time, the PANEL SPEAKER is active as a microphone. This allows another operation crew member to talk to the occupants using the PANEL SPEAKER even if the operator is away from the 2810E-2001 using the Remote Push-to-Talk Module in 2-Wire mode.

  • Page 25 Common sources are feedback between the operator's headset microphone and the PANEL SPEAKER of the 2810E-2001. If the operator wants to operate with the headset and leave the PANEL SPEAKER on, Amron recommends the operator move away from the 2810E-2001 by using the Amron Model 2822-28 Remote Walk-and-Talk Module.
