Once the correct amplification level is reached, the
reading (measurement) will be displayed in green
and a "smiley" :-) will appear in the place where
previously the triangular amplification guidance icon
was shown.
When the reading (measurement) is displayed in
red, the amplification is too high and will need to be
reduced by pressing the "arrow down" button.
When ''-.-'' is displayed on the default screen or in
orange in the streaming mode, the amplification
is too low and will require increasing by pressing
the "arrow up" button. In both cases, i.e. when the
amplification is too low or too high, the amplification
should be adjusted until the reading (measurement)
is displayed in green and the smiley :-) appears in
the left hand top corner.
To switch between the default screen and the
streaming screen press the on/off button (4)
once. An histogram giving a brief history of the
measurement is dynamically displayed. The
amplification adjustment is not available anymore.
2.1 Using the headphones:
To enhance the hearing experience, the audio
volume of the headset can be adjusted by pressing
the left and right arrows (5) until the sound level is
comfortable.
Avoid setting the sound too low as otherwise some
signals may not be heard and possible leaky spots
overlooked. Connect the headphones here (3).
The current volume setting is displayed (8) only
when a headset is connected.
2.2 Graphical streaming screen
Press the ON/OFF button once to toggle between
the default screen and the graphical streaming
screen.
