Gain
Adjusts the preset overall gain of the instrument.
Ideally this should be set to a comfortable level when
the volume control is around 3. This will leave the
user with approximately 10 dB reserve gain. But
for many profound hearing losses, the prescribed
VC setting might be set higher than 3 to provide
sufficient gain.

Step 2c: Check the Frequency Response
Crossover Frequency
Adjusts the frequency at which point
the A-Gram slope circuit cuts the
low and high frequencies. The
trimmer may be used to fine-tune
the frequency response to provide
a better setting if feedback is a
problem. Alternatively it may be
adjusted automatically as part of
the Feedback Management routine
to provide an optimal setting if
feedback is a problem.
A-Gram Slope
Adjusts the low frequency sounds
(LC) or high frequency sounds
(HC) according to the slope of the
audiogram.
