Setting maximum volume control and bass reduction
Note: Setting and adjusting hearing
instruments is best performed by
your hearing care professional.
This is especially true when your Comfort Duett
is used with Hearing Aids.
Maximum volume control
Comfort Duett is equipped with a control that limits
the amplification level. Too high amplification level
increases the risk of an unpleasant acoustic feedback,
plus damage to the ear drum. The maximum volume
control is placed on the back of Comfort Duett, as
seen in the picture. The control is adjusted with a 2
mm screwdriver. The level used, 1-9, is shown in the
small, square display window. Level 1 is the lowest
amplification level with level 9 is the highest, giving
an amplification boost of 60 dB. The factory default
level is pre-set to level 2.

Using a neck loop
Appropriate maximum amplification level when
using a neck loop is 1-6. If a max level 6 is too weak,
adjust the T-level on the hearing aid.
Warning: Do not adjust the maximum volume
control to a higher level than needed when the
volume control is in its maximum level!
If the maximum volume control is incorrectly
adjusted the maximum volume might be harmful!
Bass control
The bass level can be adjusted with the bass reduction
control. The control is the red switch found when
you remove the battery cover. If you prefer less bass,
the small red switch should be moved towards the
top of Comfort Duett (with a pen, paper clip or small
screw-driver).
This adjustment also adjusts the sound from external
sources connected to Comfort Duett.
