Daily maintenance
It is important to keep your hearing instrument clean and dry. On a daily basis, clean the hearing instru-
ments using a soft cloth or tissue. Remove any wax or debris from hearing instruments using a brush and/
or a wire loop. In order to avoid damage due to humidity or excessive perspiration, the use of a drying kit
is recommended.

of the dial.
