MAN 078L
Neckloop Telecoil Coupler
Instructions For Use
The NKL 001 Neckloop is designed to
magnetically couple the audio output from a
Williams Sound unit into a hearing aid equipped
with a telephone coil. It will also work with any
audio device which has a 8-16 Ohm audio
output through a 3.5mm jack. The neckloop
works only with hearing aids equipped with a
telephone coil (T-Switch).

Using the Neckloop
1. Place the neckloop over your head and around your neck as in the picture above.
2. Slide the cord lock upwards to a comfortable position. This helps keep the
neckloop in optimal position for coupling with your hearing aid.
3. Plug the neckloop into the earphone jack on the Williams Sound unit. Turn the unit
on and set the volume control to “3,” or about half of full volume.
4. Turn the switch on your hearing aid to the “T” position and adjust the volume for
comfortable listening.
5. If the sound is weak, increase the volume on the Williams Sound unit, then on your
hearing aid.
How the Neckloop Works
The neckloop is a miniature audio induction loop worn around a user’s neck.
It uses invisible magnetic energy to transfer the electrical signal from a sound
source (Pocketalker, FM Receiver, etc.) directly into a hearing aid equipped with a
telephone coil.
When the audio signal from an earphone or loudspeaker jack is fed into the neckloop,
a magnetic eld is created around the neckloop wire and user’s head. As the audio
signal varies, the magnetic eld also varies. The varying magnetic eld induces a small
electrical current in the hearing aid T-coil corresponding to the original audio signal.
The T-coil’s signal is then amplied and converted to sound by the hearing aid.
Using the optional Universal Extension cord
You can use the neckloop with the Universal Extension cord accessory (WCA 007
WC) to listen to a portable radio, TV, or other sound source. This 4m (13’) cord
allows you to sit at a comfortable distance for TV listening. Plug the neckloop into the
Universal Extension Cord, then plug the Extension Cord into the earphone or speaker
jack on the sound source Then follow the directions above for using the neckloop.
NOTE: Cord lock adjustment will slightly affect the induction eld strength.

Safety Breakaway Feature
