Why are my Phonak hearing aids regularly beeping?

My hearing aids play a beep regularly.

Some hearing care professionals offer dedicated trial hearing aids marked PHONAK Trial™. The trial period is limited. A tone is played in the hearing aids 1x/hour for 6 days after the expiration time. Then, the tone will play 1x/minute.
Please contact your hearing care professional to replace the hearing aids or to renew the trial period.
