How to fix interference in Contacta PRO Hearing Aid loop?
- D
  Deborah PenaJul 28, 2025
  If you're hearing interference like buzzing, whistling, or hissing through your Contacta induction loop, it could stem from poor input signals. To resolve this, power off the hearing loop driver and check if the interference is coming from an external source. If the issue persists, it might be an internal problem. Disconnect the input signals; if the sound disappears, examine the inputs.

What to do if Contacta Hearing Aid loop has output but no sound?
- H
  huntervasquezAug 7, 2025
  If the loop output level on your Contacta Hearing Aid indicates current is flowing, but you hear nothing in the loop, it could be due to a shorted feeder cable. Check the feeder cable, although the hearing loop driver will usually refuse to tune to shorted feeder. Another possibility is that the loop listener is not working or is being used too far from the loop; in that case, check the listener and location.

Why is my Contacta PRO Hearing Aid driver so hot?
- M
  Meghan BruceAug 16, 2025
  If your Contacta hearing loop driver is excessively hot to the touch, it could be due to a large amount of mains hum present on the input. In that case, check the input signal source. Another possible cause is that an incorrect hearing loop driver is being used.
