Why Does Echo Occur on a Hard Terminal?

  • The echo may be caused by environmental factors. It is recommended that sound-absorbing materials be used.
  • The sound pickup device of the hard terminal is too close to the speaker. The recommended minimum distance is 50 cm.
  • The speaker volume is too high. Lower the speaker volume.
  • The hard terminal volume is too high. Use the default 15 volume levels of the hard terminal.
  • If the audio is output from the TV speaker, the echo may be caused by a large TV delay or the TV sound effect. Disable the sound effect.
  • Contact the after-sales personnel of the hard terminal to check whether the configuration of the hard terminal is correct.
