CAUTION FOR PACEMAKER USERS
(Risks) The use of the CLEAR/DEX should not interfere with
other devices such as a pacemaker. However, to be extra
cautious, Widex follows the guidelines recommended by the
manufacturers of implantable defibrillators and pacemakers for
their patients when using mobile phones. Specifically, hearing
aid wearers who also use a pacemaker should
•Keep the hearing aids at a distance of at least 15 cm/½ foot
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.

INSTRUCTIONS FOR LANYARD USAGE

The breakaway buckle of the lanyard must be positioned at the
back of your neck (1).

TRANSMISSION
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 indicat-
ed 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 trans-
mission 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.
• Press the key a third time to stop transmission. The
hearing aids will enter the Master program, as indi-
cated by a voice message or beep tones. The green
LED will change briefly to red and then off.

20-04-2011 15:27:35

If you carry your controller around with you and move
outside the operating range, transmission will be inter-
rupted 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 acous-
tic 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 trans-
mission.
