Five troubleshooting tips to stay on air

Are you having any issues with your Cochlear™ Baha® 5 Sound Processor? Here are the most common questions raised by Baha 5 users – and how to troubleshoot them.

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. Watch a video about how to change batteries in a Baha 5 Sound Processor.

Make sure the battery is inserted correctly
It should sit with the + sign facing upwards.

Check the battery compartment is completely closed

My sound processor has stopped working

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 two sets of four short beeps.

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

Here are five tips to improve your sound quality.

Check the battery door
Is it completely closed? Is the external casing damaged?

Keep it dry
Use a dry aid kit overnight to remove any moisture.

Check your snap coupling connection (Baha Connect) 
The snap coupling connects your sound processor into your abutment: is there a loose connection?

Check your external magnet connection (Baha Attract)
Is there a loose connection between your external magnet and your sound processor?

You may need a programme adjustment
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.

Avoid causing feedback
Make sure anything you might wear on your head or in your hair, such as glasses, doesn’t touch your sound processor. Also ensure the sound processor is not touching your head or ear. 

Check the battery door
It must be completely closed.

Check for external damage
If there are any cracks in the casing of your sound processor, you may need a new one.
