Before using REM AutoFit
Hearing aid settings during measurement
Step 2: Unaided
Perform an otoscopic examination of the ear canal prior to doing REM to ensure
no excessive wax or other contraindications.

a.
Position the client in front of the loudspeaker at the distance recom-
mended by the REM system (usually 0.5-1 m). Instruct the client to
remain still during each sequence of measurements.
b.
Place the probe tube in the client's ear canal. The recommended inser-
tion depth of the probe tube is 6 mm from the tympanic membrane and
a minimum of 5 mm beyond where the sound outlet of the instrument
will be positioned for the aided measurements in Step 3: Aided.
c.
Verify the probe tube placement in the ear canal by performing
otoscopy.
d.
Click Start on the relevant side to measure one side. To calibrate both
sides, click Both. Depending on the REM system, binaural measurement
may take place simultaneously or sequentially.
e.
The system automatically turns off the signal when the measurements
are complete. If you need to stop the measurement prior to completion,
click Stop.
f.
Ensure that the unaided gain at 6 kHz intersects the x-axis at approxi-
mately 0 dB (+/- 5), if possible. If it does not, reposition the probe tube.
The grey curve that is already shown is a predicted REUG.
g.
If you are satisfied with the unaided measurement, proceed to
Step 3: Aided.
h.
To re-measure the unaided measurement, repeat points d-g above.
Note: if REM AutoFit adjustments are subsequently applied to the fitting (in
Step 4: Finish), the unaided measurement (REUG) is saved to the REUG tool
and will overwrite any previous REUG. If REM AutoFit is discarded or exited
prematurely, the unaided measurement is not saved.
