(Benefits)
The use of wireless transmission allows convenient
and synchronized control of hearing aid functions. The CLEAR
wireless hearing aids share input information between the two
partner hearing aids. In so doing, the wearers would experience
the following additional user benefits (only when wearing binaural
CLEAR hearing aids).
Synchronization of volume control settings between hearing
aids
– The volume in both hearing aids will change when the VC is
adjusted on one ear.
Synchronization of listening programs between hearing aids
– The
same listening program is used in both hearing aids when one is
changed by the user.
Surveillance of partner hearing aid
– The hearing aid(s) will signal
an alert (“partner check”) when a hearing aid battery has expired,
or that one of the hearing aids has fallen off. In rare instances, a
much stronger wireless source nearby may activate this alert. This
serves as an early warning to the wearer of such service interrup-
tion.
Coordination of compression
– The CLEAR hearing aids maintain
the intensity level difference between ears (inter-aural level dif-
ference, ILD). In some situations where speech is presented to
one side and noise the other side, this coordinated action could
enhance the relative loudness of the speech sounds to the noise
background and improve speech understanding for some wearers.
More accurate identification of feedback
– The CLEAR hearing aids
distinguish between “true” hearing aid whistling (or feedback) and
music sounds to prevent unnecessary feedback cancellation and
preserve natural sound quality.
(Contraindications):
• Congenital or traumatic deformity of the ear
• Active drainage from the ear within 90 days
• History of rapid progressive hearing loss within previous 90
days
• Acute or chronic dizziness
• Sudden unilateral hearing loss in previous 90 days
CauTion
(risks)
The use of the CLEAR/DEX should not interfere with
other devices such as a pacemaker . However, to be extra cau-
tious, Widex follows the guidelines recommended by the manu-
facturers of implantable defibrillators and pacemakers for their
patients when using cell phones . Specifically, hearing aid wear-
ers who also use a pacemaker should
• Keep the hearing aids at a distance of at least 15 cm/6 inches
away from the pacemaker and
• Do not carry the hearing aids (and/or any of the DEX accesso-
ries) in a shirt pocket or close to the chest .
• If any interference is observed, do not use the hearing aids
(and/or DEX) and contact your pacemaker manufacturer and
hearing healthcare professional immediately .
