  First, ensure that the tone remotes are generating a function tone that the ITA2000A uses for keying the radio. Then, check that one of the ITA2000A PTT outputs is connected to the radio (Pin 6 for ground keying or active high). Also, check the telephone line continuity from the ITA2000A to the remote and ensure that the telephone line is balanced by making sure neither side of the telephone line is grounded.

  Verify that the radio is being keyed when transmitting to the ITA2000A from a tone remote. If the radio is not being keyed, refer to the section above describing the radio not being keyed. Ensure that the ITA2000A audio output (J2-12) is connected to a point in the radio that causes the audio to be transmitted when the radio is keyed. Verify that the ITA2000A TX output level is properly set and there is no more than 20 dB of loss in the telephone line. If appropriate, adjust the transmit audio output or desk set microphone sensitivity.

  Sarah LopezAug 26, 2025
  To resolve squelch noise or lack of RX audio, take these steps: 1. Ensure that the telephone line is balanced by making sure neither side of the telephone line is grounded. 2. Ensure that there is no more than 20 dB of loss in the telephone line. 3. Ensure that the ITA2000A audio input (pins 3 and 11) is connected to a point in the radio that has receive audio present when a valid carrier and PL/DPL (if needed) is detected. 4. Check that the volume pot has not been turned down if the ITA2000A RX audio is connected to the volume pot of the radio's speaker. Connect to the high side of the volume pot. 5. Ensure that the proper input polarity of the CSQ detect has been set with SW1-2. 6. Ensure that the scan rate is properly set using SW2-5 through SW2-7.

  First, ensure that there is a telephone line audio path from the ITA2000A to the tone remote desk set. Then, check that neither fuse is open on the telephone line. Finally, ensure that the ITA2000A is connected to a dc or ac (with a dc power supply option) power source.

  Ensure that the proper input polarity of the CSQ detect has been set with SW1-2. Also, ensure that SW2-1 through SW2-4 are set according to the maximum number of channels to be scanned. If SW1-8 is configured for resume scan after PTT, ensure that PTT is generated by the remote. Finally, ensure that there is no off-hook mic or shorting plug connected to the mic port of the ITA2000A, and that the monitor pin of the accessory connector is not asserted.
