Before starting to use your new hearing instrument it is
important that you spend some time learning the user
operated controls on the instrument.
BaTTERy COMPaRTMENT
Before you start to use your hearing instrument, open
the swing-out battery door and make sure there is a
fresh battery in the compartment.
TuRNiNg ON aNd Off
Turn your hearing instrument
on by closing the battery
door. Turn your hearing in-
strument off by pushing in on
the small knob located on the
battery door. This will cause
the battery door to open.
The hearing instrument will
always be in program 1 when
it is first turned on. Additional
information about the pro-
grams can be found on page
10.
Turning your hearing instru-
ment off, when not in use,
will increase the battery life.
Therefore, it is recommended that you turn off your
hearing instrument at night and open the battery door
completely. It will also allow moisture in your hearing
instrument to evaporate and will increase the instru-
ment’s lifespan.
