Locating the serial number

Locate Kanso serial number

Should your Kanso Sound Processor require service or need repair, you may be asked for your serial number. Your serial number is located underneath the battery cover on the backside of the Kanso Sound Processor. In order to serve you better, please locate the serial number on your sound processor prior to calling Cochlear.


For everyday use, the Kanso Sound Processor uses two high power P675 zinc air disposable batteries designed for Cochlear implant use.

NOTE: You will need to use either LR44 alkaline or nickel metal hydride disposable batteries when using the Aqua+ for the Kanso Sound Processor.*

*The Kanso Sound Processor with the Aqua+ is water resistant to level IP68 of the International Standard IEC60529. This water protection rating means that the sound processor with the Aqua+ can be continuously submerged under water to a depth of 3 meters (9 feet and 9 inches) for up to 2 hours. This water protection only applies when you use the Aqua+ and LR44 alkaline or nickel metal hydride disposable batteries.

Battery life

Batteries should be replaced as needed just as you would with any other electronic device. Battery life varies according to the programs used each day, accessory usage, your implant type and the thickness of skin covering your implant. Your Kanso Sound Processor has been designed to provide the majority of users with a battery life of more than 16 hours for typical use with zinc air batteries. However this will vary depending on your system settings and hearing situations. To help you get the longest life from the batteries, your sound processor will turn off two minutes after you take it off your implant.

Lock/unlock the battery cover

The battery cover has a tamper resistant lock to help prevent children opening the battery cover.

1. To lock, turn the locking screw clockwise with the battery cover locking tool until it is horizontal.

2. To unlock, turn the locking screw counterclockwise until it is vertical.

CAUTION: Always check the locking screw is unlocked before attaching or removing the battery cover.

Pair with remotes

You need to pair your sound processor to your CR210 Remote Control or CR230 Remote Assistant to use their control and monitoring functions. Please see your remote’s user guide for details.

Pairing allows your processor to communicate to the remote assistant. If a Sound Processor is not paired with the remote assistant, the 'No Processor Paired' screen will display. Before pairing, ensure the processor is switched on.

Hold the Kanso Sound Processor on the coil guides at the back of the remote assistant.

The Pair Processor screen will display.

Press the OK button to pair.

When pairing is complete, the Processor Paired screen will display, followed by your Home screen.

If you are a bilateral user, you will need to repeat these steps for your second Sound Processor.
