My sound processor won’t turn on

This might be your battery, which can be affected by daily use, the volume setting, use of wireless audio streaming, the sound environment, and battery strength. There are three things you can do to troubleshoot this common problem.

  • Replace the battery.
    • Ensure you remove the sticker on the side of the battery.
  • Make sure the battery is inserted correctly.
    • It should sit with the + sign facing upwards.
  • Check the battery compartment is completely closed.
    • Watch this video below about how to change the battery in a Baha 5 Sound Processor.

My sound processor works for 5-10 minutes, then stops

Try replacing the battery. Your Baha 5 Sound Processor plays a chime to let you know it’s time to change the battery. It plays three notes, followed by a lower note twice.

The sound quality from my sound processor is poor or isn’t as good as it was

Here are five troubleshooting tips to improve your sound quality.

  • Check the battery door.
    • Is it completely closed? Is the external casing damaged?
  • Use a dry aid kit overnight to remove any moisture.
  • Check your snap coupling connection, if you have the Baha Connect system.
    • The snap coupling connects your sound processor into your abutment: is there a loose connection?
  • Check your external magnet connection, if you have the Baha Attract system.
    • Is there a loose connection between your external magnet and your sound processor?
  • You may need a new program.
    • If none of the above solves the issue, your sound processor may need a programming adjustment. Check with your clinician.

I hear feedback or whistling

There are four things you can try.

  • Make sure anything you might wear on your head or in your hair, such as eyeglasses, doesn’t touch your sound processor. This can cause feedback.
  • Check the battery door is completely closed.
  • Check for external damage. If there are any cracks in the casing of your sound processor, you may need a new one.
  • You may need a new program. If none of the above solves the issue, your sound processor may need a programming adjustment. Check with your clinician.
