Your hearing instrument specialist can program the possible
adjustment range for you. If you do not want to use the
volume control, then your hearing instrument specialist can
also switch it off. Turning the volume control then does not
change the adjustment of your PRISMA 2 D SP hearing
instrument.
PRISMA 2 D SP hearing
instruments are fully auto-
matic. It is therefore not
necessary for you to change
the loudness manually.
However, if you still wish
to do so, PRISMA 2 D SP
offers you a volume control.
