How to Replace a Retention Lock on an Phonak Audeo S, Q, V or B Hearing Aid

A retention lock assists in keeping your hearing aid securely in your ear.

It may need changing from time to time, so that your hearing aid remains secure when inserted.

There are 2 different fits of retention locks, designed to match the size of your receiver - S and P.

Retention locks aren’t side-specific, so can be fit to both right and left hearing aid receivers.

Now have a closer look at the replacement retention lock. You will notice that the tail does not sit perpendicular to where it attaches to the receiver; rather it sits at an angle.

Line the retention lock up with the tail protruding on side of the receiver with the writing on it. For best fit, you will need to attach the new retention lock so that the tail angles TOWARDS the receiver wire. Slide the retention lock all the way to the end.
