The Oticon CROS transmitter coupled with a compatible Oticon hearing
aid (see overview below) is a solution for people with single‑sided
deafness (SSD).
A CROS fitting is appropriate when hearing on the better ear is normal,
whereas a BiCROS fitting is appropriate when hearing on the better ear
is impaired and hearing loss must be compensated for.
In this guide, both fitting scenarios are described in a few simple steps.
1. Place CROS transmitter and receiving hearing aid within 8‑12 inches of each
other on a table or on the patient’s ears.
2. Family/Selection step:
Detect the hearing aid on the better ear. If the hearing aid family and/or style
supports a CROS fitting, the CROS transmitter will appear for selection in the
Style list for the other ear.
The CROS transmitter only exists as a miniRITE T style.
3. Selection step:
Select CROS transmitter for non‑hearing aid ear. Once selected, the CROS
transmitter and receiving hearing aid will automatically pair.
The CROS transmitter is not detected or connected to the software, but it is
actively streaming throughout the fitting. Make sure both devices have fresh
batteries (or are fully charged) and are turned on.
4. Fitting step:
The patient can now hear streamed sound from the CROS transmitter in the
receiving hearing aid.
Check active streaming by running a finger along the transmitter microphone
and listen for the microphone activity in the receiving hearing aid.
5. Fitting step:
Go directly to CROS/BiCROS tab in left taskpane to select mode: BiCROS, CROS,
or No CROS/BiCROS.
The selection of mode controls which microphones are in use. It is possible to
create several programs in the hearing aid, each with its own mode.
6. Fitting step, CROS mode:
Ask your patient to listen to the sound coming from the right and left sides
to determine appropriate transmission level. In CROS mode, the hearing aid
microphone is off by default.
In Fine‑tuning, choose appropriate adaptation step (1, 2 or 3) and adjust
overall gain of transmitted signal as needed.
Go to step 8.
