    These spikes can exceed 1kV! Such spikes can be high enough to cause the input fuses on the 2810E-02 internal battery charger to blow and, in extreme cases, actually damage the charger circuitry. Amron has designed this battery charger to isolate such faults to ensure that they will not cause a safety issue for the operator or chamber occupants.

  • Page 16: Maintenance

    The following are a series of step-by-step procedures to perform a functional check of your 2810E-02 communicator using only a headset. These steps check all communication functions of the 2810E-02 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 17 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.

  • Page 18: General Maintenance

    Select a work area where the communicator and wires connecting to it are out of everyone's way so it does not get knocked over. The 2810E-02 rechargeable battery should be recharged after use or as soon as possible when the BATTERY CONDITION INDICATOR starts blinking.

Plug 2810E-02 into AC power and allow battery to charge for 4 hours (depending of the age of the battery and the surrounding temperature). 4.2.2 RECOMMENDED MAINTENANCE SCHEDULE The following sections outline the recommended scheduled maintenance for the 2810E-02.

  • Page 20: Troubleshooting

    The BATTERY CONDITION INDICATOR indicates the battery level or state-of- charge by monitoring the battery voltage. The voltage has to be 9 Volts or greater for the 2810E-02 communicator to operate. If the BATTERY CONDITION INDICATOR indicates a low (blinking LED) or bad (off LED) after charging, then either the battery is bad and needs to be replaced or the charger has malfunctioned.
  • Page 21 4.3.7 FEEDBACK - FULL DUPLEX (4-WIRE) MODE There are two forms of feedback that can affect the 2810E-02: acoustic feedback and cable crosstalk. Acoustic feedback occurs when an active microphone is close enough to pick up and amplify the signal from a speaker or earphone. The required distance between the microphone and speaker/earphone is dependent on the volume setting and the amount of acoustic isolation.
  • Page 22 Common sources are feedback between the operator's headset microphone and the PANEL SPEAKER of the 2810E-02. If the operator wants to operate with the headset and leave the PANEL SPEAKER on, Amron recommends the operator move away from the 2810E-02 by using the Amron Model 2822-28 Remote Walk-and-Talk Module.
