Description of device
Your hearing aid is used with an ear-set which consists
of an earwire and an earpiece, in which the receiver
is placed. The hearing aid uses a proprietary wireless
technology, the WidexLink, to enable communication
between the left and the right hearing aid, as well as
between the hearing aids and the DEX accessories.
Your hearing aid may be provided with a listening
program called Zen. It makes musical tones (and some-
times a rushing noise) in the background. These sounds
are shaped according to your hearing loss.
