  Andrea BrooksAug 12, 2025
  If there is no sound in the built-in loudspeakers, verify the ‘Loudspeaker Volume’ setting using the interactive menu on the CU or the browser control. Also, using the browser control, check that the setting ‘CU 5905 Setup * Audio * Loudspeaker Control * Microphone ?> Loudspeaker’ is set to ‘On’. Finally, check in ‘CU 5905 * Audio * Audio Output * Group Setup‘ that the seats are selected in ‘Group A’, as this group is used as the source for the built-in loudspeakers. If a unit is not selected in ‘Group A’ the sound from this unit will not be heard in the built-in loudspeakers.

  If the light rings in the microphone are constantly flashing, check the cables to ensure the digital communication from the central unit to the conference units is established. Also, check that all the connectors on all cables are firmly inserted in the socket on the units and that the feeding cables from the conference units are inserted in the ‘DCS?LAN’ socket on the CU 5905.

  If the sound from an interpreter unit cannot be heard in the headphone, check if the unit is configured as an interpreter unit. Also, check the headphone volume control on the units, the channel selection on the conference units, and ensure the plug from the headphone is firmly inserted in the headphone socket. Finally, verify that the light ring on the microphone on the interpreter unit is lighting and that the gooseneck microphone is firmly inserted in the microphone socket.
