Connecting Micro Receiver DT20 to the MED-El OPUS 2 and performing functional listening evaluation
a.
Insert Micro Receiver DT20 into the bottom of the FM battery pack cover.
b.
Turn on the sound processor
c.
The sound processor will automatically detect Micro Receiver DT20 .
d.
Perform a functional listening evaluation test as follows:
•
Turn off Micro Receiver DT20. Conduct a listening test in quiet, at a Speaker-to-Listener distance of 1 metre.
•
Turn on Micro Receiver DT20. It automatically turns on in the R-only mode. Repeat the same listening test in quiet, at a Speaker-to-Listener
distance of several metres this time. The user´s speech recognition performance should be almost the same in the both cases.
•
If not, use Programmer DT20 to optimize the output level of Micro Receiver DT20 until almost the same performance is obtained.
•
Note: The R+M mode is recommended to be used in quiet. The R-mode provides the user with a good speech recognition performance in
noise.
