With either TV or audio connected
• Press the transmission on/off key on the controller once to
start transmitting from the connected source. An acoustic
­signal will sound in your hearing aids, and the transmission LED
will turn green.
• Press the key again once to stop transmission. The hearing aids
will enter the Master program as indicated by a voice message
or beep tones. The green LED will change briefly to red and
then off.
With both TV and audio connected:
• Press the transmission on/off key on the controller once to
start transmission from the TV. An acoustic signal will sound in
your hearing aids, and the transmission LED will turn green.
• Press the key a second time to transmit sound from the audio
source instead. An acoustic signal will sound in your hearing
aids.
25
• Press the key a third time to stop transmission. The hearing
aids will enter the Master program, as indicated by a voice
message or beep tones. The green LED will change briefly to
red and then off.
If you carry your controller around with you and move outside the
operating range, transmission will be interrupted and your hearing aids will switch to the Master program. The LED will flash at
slow intervals to indicate that transmission has been interrupted.
The change will be indicated by a voice message. If your hearing
aids are set up with beep-tone indication instead, no acoustic
­indication will sound.
If you come in range again, the controller will detect the signal
from the TV/Audio and restart transmission. A sound will be
heard in the hearing aids. The LED will light constantly rather than
flash.
Note that the LED may continue to be red if you chose to turn off
the hearing aid microphones during transmission.
26

(Benefits) The use of wireless transmission allows convenient and synchronized control of hearing aid functions. The 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 hearing aids).
39
Synchronization of volume control setting 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 interruption.
Coordination of compression – The hearing aids maintain the intensity level
difference between ears (inter-aural level difference, 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 hearing aids distinguish between “true” hearing aid whistling (or feedback) and music sounds to prevent unnecessary feedback cancellation and preserve natural sound quality.
40
(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

43
Quality of Service for Wireless Technology in the WidexLink System
WidexLink wireless technology enables communication between two partners of a binaural pair of Widex wireless hearing aids and with their matched
external devices. The requirements for the quality of service (QoS) vary
among the various components and their intended user scenarios.
During daily use, the requirements on audio streaming from ­TV‑Controller to
hearing aids include a BER better than 10-3. The communication is simplex
with a bitrate of 212 kbits/s. For remote control commands the QoS requirements include a BER better than 10-2. The lower BER requirement results
from redundant transmissions. Each key press results in transmissions of 7
data packages of which only one is needed for a successful communication.
The requirements from TV-Base to TV-Controller include a BER ­better than
10-3. The communication is semi duplex with a bit rate of 2Mbits/s and a total latency <10ms (including the link from the ­TV-Controller to the hearing
aids) to insure high quality audio transmission.
Wireless Security Measures
Security of the wireless signals is assured through device system design that
includes:
44
• Individual MAC address for each unit which is checked during each
transmission.
• A built-in pairing table which specifies valid and legitimate pairing
among units
• A proprietary Widex communication protocol which checks the package numbers during each transmission.
• A Cyclic Redundancy Check (CRC) to check data validity and correct
errors.

Important notice for prospective hearing aid users
Good health practice requires that a person with a hearing loss have a medical evaluation by a licensed physician (preferably a physician who specializes in diseases of the ear) before purchasing a hearing aid. Licensed physicians who specialize in diseases of the ear are often referred to as otolaryngologists, otologists, or otorhinolaryngologists. The purpose of medical eval-
55
uation is to assure that all medically treatable conditions that may affect
hearing are identified and treated before the hearing aid is purchased.
Following the medical evaluation, the physician will give you a written statement that states that your hearing loss has been medically evaluated and
that you may be considered a candidate for a hearing aid. The physician will
refer you to an audiologist or a hearing aid dispenser, as appropriate, for a
hearing aid evaluation.
The audiologist or hearing aid dispenser will conduct a hearing aid evaluation to assess your ability to hear with and without a hearing aid. The hearing aid evaluation will enable the audiologist or dispenser to select and fit a
hearing aid to your individual needs.
If you have reservations about your ability to adapt to amplification, you
should inquire about the availability of a trial-rental or purchase-option program. Many hearing aid dispensers now offer programs that permit you to
wear a hearing aid for a period of time for a nominal fee after which you may
decide if you want to purchase the hearing aid.
Federal law restricts the sale of hearing aids to those individuals who have
obtained a medical evaluation from a licensed physician. Federal law permits
56
a fully informed adult to sign a waiver statement declining the medical evaluation for religious or personal beliefs that preclude consultation with a physician. The exercise of such a waiver is not in your best health interest and its
use is strongly discouraged.
Children with hearing loss
In addition to seeing a physician for a medical evaluation, a child with a hearing loss should be directed to an audiologist for evaluation and rehabilitation
since hearing loss may cause problems in language development and the
educational and social growth of a child. An audiologist is qualified by training and experience to assist in the evaluation and rehabilitation of a child
with a hearing loss.

are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged
58
to try to correct the interference by one or more of the following
measures:
— Reorient or relocate the receiving antenna.
— Increase the separation between the equipment and receiver.
— Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
— Consult the dealer or an experienced radio/TV technician for help.

This equipment complies with FCC radiation exposure limits set forth for
an uncontrolled environment. This transmitter must not be co-located
or operating in conjunction with any other antenna or transmitter.
Changes or modifications to the equipment not expressly approved by
Widex could void the user’s authority to operate the equipment.
Industry Canada Statement / Déclaration d’industrie Canada
Under Industry Canada regulations, this radio transmitter may only
operate using an antenna of a type and maximum (or lesser) gain
approved for the transmitter by Industry Canada.
To reduce potential radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent isotropically
radiated power (e.i.r.p.) is not more than that necessary for successful
communication.
59
This device complies with Industry Canada licence-exempt RSS
standard(s). Operation is subject to the following two conditions:
(1) this device may not cause interference, and
(2) t his device must accept any interference, including interference that
may cause undesired operation of the device.
Conformément à la réglementation d’Industrie Canada, le présent
émetteur radio peut fonctionner avec une antenne d’un type et d’un
gain maximal (ou inférieur) approuvé pour l’émetteur par Industrie
Canada.
Dans le but de réduire les risques de brouillage radioélectrique à
l’intention des autres utilisateurs, il faut choisir le type d’antenne et son
gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.)
ne dépasse pas l’intensité nécessaire à l’établissement d’une
communication satisfaisante.
Le présent appareil est conforme aux CNR d’Industrie Canada
applicables aux appareils radio exempts de licence. L’exploitation est
autorisée aux deux conditions suivantes:
(1) l’appareil ne doit pas produire de brouillage, et
(2) l’utilisateur de l’appareil doit accepter tout brouillage radioélectrique
subi, même si le brouillage est susceptible d’en compromettre le
fonctionnement.
