with Cochlear Implants
There are three main manufacturers of Cochlear Implants and each provide specific wireless devices to go with their product.

Advanced Bionics

Med-el
Sonnet and Rondo Wireless connectivity is explained on the Med-el website
Each of these devices can be connected to a radio aid. Some Cochlear Implant devices will only connect to certain radio aid systems and in some cases, an upgrade of a speech processor may mean a change of radio aid system is needed. Each manufacturer has different ways of connecting a radio aid. In some instances, they also have their own system that may not be compatible with other systems. (This is something to consider when there is more than one radio aid user in one setting).
It is important that the family, Teacher of the Deaf, and the Cochlear Implant Centre all work together on this. The audiologists at the CI Centre will need to enable the speech processor to work with a radio aid and make adjustments to the internal settings through the manufacturer’s software.
The Ear Foundation Sounding Board website gives information on different systems and how they are set up with the different Cochlear Implant devices. This is especially useful for some of the older systems, but see also the websites of the Cochlear Implant devices above and the manufacturers of the radio aid systems.
Radio aid readiness for CI users
The fitting a radio aid with a Cochlear Implant user needs careful timing and planning. It may seem unusual that an older child who has previously been using a radio aid, post CI surgery may need to wait before resuming the use of a radio aid. This is because in the first six months post-implant, the CYP will have many tuning appointments at the Implant Centre. If the CYP is unhappy with their listening experience after a tuning appointment it would be difficult to know if was due to changes to the mapping of the speech processor(s) or the addition of a radio aid, therefore a stable map is needed. There may be the occasional exception where a CYP can report accurately on their listening experience.
The Cochlear Implant FM training tool and the FM ChIP are useful tools which can help with ascertaining the CYP's readiness to be fitted with a radio aid.
