caring for the hearing instrument
Every ear canal produces ear wax (cerumen) which may clog up the sound outlet or the
ventilation opening of the ear mould. To prevent wax accumulation causing a change
in performance, the guidelines in this section should be followed.
When handling a hearing instrument, keep it over a soft surface to avoid damage
if dropped.
Before retiring at night:
• Make sure that there is no ear wax in any of the earmould openings since it may reduce
the hearing instrument's efficiency.
• Open the battery door to allow air to circulate.
