domes no low-frequency gain is provided in the initial setting
due to the dominating natural sound.
Therefore the LF region is disabled (greyed out) in the fitting.
If you want to make adjustments in the LF region, expand the
region and you will get access to the underlying frequency
channels.
Reserve Gain
The VC Reserve Gain displays the volume range between the
preferred level and the instrument’s possible maximum gain in
the range of 0-10 dB, at 2.5 dB steps. To modify the Reserve
Gain, adjust the instrument’s gain or change the feedback
limit.
The volume control ranges 30 dB: -20 dB to m 10 dB
from the preferred level.
Compression Ratios
Click on the ‘CR’button between the right and left graphs to
check the compression ratio.
Program Manager
In the Program Manager you can activate, configure, delete, and
change the order of the programs. For general programs you can
choose between the NAL NL1 and DSL v5.0 fitting rationales.
Two phone programs exist, Microphone (M) or telecoil (T). You
choose whether you want to activate the phone program on the
left or right ear. By default a copy of P1 reduced will be placed in
the other instrument.
If you have an
Auto Phone
in the instrument, you can activate
the automatic functionality in the lower right corner. You do
not have to add a Phone program in P2 – P4. You can choose
whether the program should be a Microphone or a Telecoil pro-
gram (when Telecoil is available). This program is configured
either here or in the End Fitting Step.
If you are fitting ConnectLine to your Oticon Acto instruments,
adjustments to ConnectLine programs are done in the
End Fitting step.
RITE and BTE instruments are compatible with DAI and FM
shoes. When the shoe is attached to the instrument, you will
automatically have access to two extra programs:
• DAI/ FM + Microphone (default) and
• DAI/FM only.
The two programs are based on the settings in P1.
Any adjustments are handled in the End Fitting step.
