eXtra - Frequently Asked Questions
Information regarding the technical aspects of Phonak hearing aids relevant to Audiology and the hearing aid fitting.
The end of battery life beep cannot be turned off. Digital Bionics products end-of-life battery life process is as follows:
Once a low voltage level is reached, an acknowledgement beep is heard and DataLogging is turned off. This beep is, in fact, 2 beeps separated by 2 seconds. The hearing instrument is muted between the two beeps. As battery current falls further, every 30 minutes a beep will be heard, reminding the wearer to change the battery. If the battery is not changed and the battery current reaches a critical level, one more end-of-life beep is heard, all manual controls are disabled and the power-down process is started. This process involves a decrease in gain of 5 dB, every 10 seconds. After this, if the battery has not been changed, the instrument will turn off.
The eXtra tamperproofing is the same style as the Eleva, Una, and Certena. A replacement nameplate and battery door are used to tamperproof the eXtra. A paperclip or similar item is used to release the tamperproof mechanism. To re-engage the tamperproofing, simply push on the nameplate.
The Digital Bionic products offer a range of acoustic acknowledges, or beeps. These can be changed in terms of frequency and loudness. Within the schematic, acoustic acknowledges are inserted before the gain model, therefore the beep loudness is hearing loss dependent. Limiting (MPO) is applied to and affects the loudness of the beeps, too. Turning the beeps off applies only to manual interventions, not to the AutoPilot melody, warning beeps such as end-of-life, different input source (EasyPhone, EasyFM) and max/min volume reached.

eXtra BTE’s (except micro) are compatible with the ML9i receiver. The AS9 audioshoe can also be used with a universal receiver. The MyLink will also work with all Eleva models with a t-coil. The battery door will need to be changed to the FM battery door for use with the audioshoe or receiver.
Yes, the eXtra BTEs (except micro) can be used with either a wired Cros/BiCros or a wireless CrosLink System. For the wired Cros, the components are the hearing instrument, audioshoe, Cros cord, and offside mic. For the CrosLink, the components are the hearing instrument, audioshoe, CrosLink Transmitter and CrosLink Receiver.
