USING THE 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 4 m (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.



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, PM 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 field is created around the Neckloop wire and user's head. As the audio signal varies, the magnetic field also varies. The varying magnetic field induces a small electrical current in the hearing aid T-coil conesponding to the original audio signal. The T-coil's signal is then amplified and converted to sound by the hearing aid.
