Connect
Hold the Roger inspiro microphone close to Roger X (within 10
cm 4 inches) and press the Connect button.
Your patient should now report that he she has heard the
confirmation beeps (a low tone followed by a high tone).
If your patient didn’t hear the confirmation beeps, you may need to
switch the processor into the DAI program.
Repeat this connect process until your patient hears the beeps.

Roger and Cochlear™ Baha® Sound Processors 3
Getting started
1. Turn all equipment off.
2. Plug the Roger X into the Baha sound processor.
3. Switch on the Baha sound processor.
4. Select the dedicated “DAI + Mic” program, the output of the
Roger X is mixed with the signal of the Baha microphones.
5. Test the patient’s speech recognition in quiet at normal
sensitivity with the Baha sound processor alone and then through
the Roger system only (out of range of the processor microphone).
Performance should be similar between these two conditions.
If the Roger signal is too loud or too soft, the Roger inspiro may be
required to optimize the Roger volume level on the Roger X.
