## What is CI Select?

For cochlear implant users. Request manual at CISelect.questions@gmail.com or https://med.nyu.edu/research/translational-auditory-research-lab/sites/default/files/ci-select-manual.pdf
NOTE: Instructions for users of Cochlear devices with 22 active electrodes and default frequency allocation table (188-7938Hz). Users with deactivated electrodes or non-default FAT should consult the manual.
1) Audio link to iPhone:
•	N7 processor or newer: Use MiniMic 2+ with audio cable between iPhone and Mini-Mic 2+ line-in jack.
•	N6 processor or older: Connect iPhone via audio cable to speech processor.
•	Deactivate microphone input by: 
o	Using accessory-only map (consult audiologist)
o	Using remote to set 100% accessory/0% microphone mix ratio
NOTE: Current version may not work well with Bluetooth connection between the iPhone and the speech processor. Use wired connection only.
Using CI Select:
•	Adjust iPhone volume to comfortable level using speech or continuous audio.
•	Select grid boxes (each one represents a different FAT) to compare sound quality and speech intelligibility. Use "LF edge" slider or click boxes to change settings. Red square shows current setting. Default is 188Hz (standard FAT).
•	Note: Slight audio delay may occur. If bothersome, minimize acoustic input by removing acoustic component, hearing device in other ear, or using ear plug in opposite ear.
•	Test different FATs until finding best intelligibility and sound quality. App makes no permanent changes—share preferred settings with audiologist for permanent map changes.
Grid Searching Tips:
•	Tried FATs appear lighter green. Current FAT is red.
•	Click "Save Favorite" to mark promising FATs (yellow). Select multiple favorites.
•	"Delete last" removes most recent favorite. Repeat to reset grid.
Advanced Option - Extended Frequency Mode: Default grid adjusts LF edge only (sufficient for most users). For full control:
•	Click "Extended Frequency Mode" (EFM) below LF edge bar
•	This gives access to full grid with LF edges (rows) and HF edges (columns)
•	Selected box shows LF & HF intersection
•	Toggle EFM switch to return to default view
For non-standard settings, reference the full manual for detailed instructions.
