The Made for iPhone Difference

Thanks to Made for iPhone compatibility, you can stream phone calls and FaceTime® audio calls directly to your Nucleus 7 Sound Processor and enjoy music and entertainment on the go.1

You will need to pair your processor to your Apple® device to get these benefits.

Pair Your Processor with the CR310 Remote Control

Pairing allows your processor to communicate to the remote control.

1. The Cochlear CR310 Remote Control allows you to change programs, turn volume or sensitivity (if available) up and down, control audio streaming from True Wireless devices, and turn telecoil on and off.


2. Before you can use your remote control for the first time it must be paired with your Nucleus 7 Sound Processor.


3. To pair your processor with your remote control, first turn off your processor and remote control.


4. Turn back on your processor and remote control. They must both be ‘awake’ and on at all times while pairing.


5. Place the coil on the back of your remote control.


6. The remote control will show pairing in process.


7. The remote control then shows successful pairing of you left (L) or right(R) processor.


8. If you have two processors, repeat steps 3-7 for your second processor.


Locating the serial number

Should your Nucleus 7 Sound Processor require service or need repair, you may be asked for your serial number. Your Sound Processor serial number is located on the inside curve of your Sound Processor. In order to serve you better, please locate the serial number on your Sound Processor prior to calling Cochlear.
