1)
Place a probe module on each ear and insert the probe tube into the good ear
only. Position the CROS instruments on (in) the ears and turn them ON.
2)
Position the speaker at 45° to the good ear and set Instrument to [BTE].
3)
Select REAR 1 and
record a response using
[Pink noise] at Soft (55).
It should be like a normal
REUR. If not, the ear
may not be fully open.
4)
Position the speaker at
45° to the poor ear.
5)
Set Instrument to
[CROS].
6)
Select REAR 2 and
obtain a response using
[Pink noise] at Soft (55).
Adjust the response to
match that obtained in
step 3.
7)
Position the speaker directly in front of the client. Select REAR 3 and use [Pink
noise] at Soft (55) to check for a smooth response. Repeat with Instrument set
to [BTE]. An irregular response may be the result of reflections from nearby
objects (including the operator) or it may indicate phasing problems in the aids.
