Exchanging The Earpiece - Phonak Bolero M Series User Manual

18. Exchanging the earpiece

If your hearing aid is fitted with a SlimTube, you may need
to exchange or clean the earpiece.
Please check the earpiece regularly and exchange or clean
it if it looks dirty or if the hearing aid volume or sound
quality is reduced. If a dome is used, it should be
exchanged every 3 months.
