Setting automatic fade-in
This adjustment is made exclusively by the hearing aid dealer!
An adjuster (
E
) for the reduction depth of the automatic fade-in is located at the top behind
a hole in the housing. It can be turned with a 1.6 mm dia. screwdriver. Turning clockwise
increases the reduction depth of the connected hearing aid microphones.
Switching automatic fade-in and built-in microphone on/off

Two toggle switches (

screwdriver (2.6 mm).
•
If the switch (
S2
) is tipped toward the back of the unit, the automatic fade-in
feature is switched on.
•
If the switch (
S1
) is tipped toward the upper side of the unit, the built-in microphone
is switched on.
