1. General
The Mobile Inductive Loopset LPS-4 for people with hearing aids is developed to
facilitate the use of a compatible mobile phone together with T-coil equipped
hearing aids.
When using the inductive loopset, you can speak directly to the microphone inside
it. You do not need to hold a mobile phone near your ear, but you can carry it using
a carrying case, belt clip, or other accessory. The loopset does not require any
separate batteries.
The operation of the device is based on induction technology used in public
places: a loop system sends out sounds wirelessly to be picked up by the telecoil of
the hearing aid that is switched to the T mode.
The device described in this guide is compatible with phones with a Pop-Port™
interface connector (for example, the Nokia 6681 and Nokia 6682 mobile phones).
The inductive loopset can also be connected to the speech processor of a
compatible cochlear implant by using the audio output connector.
Read this user guide carefully before using the loopset. Also read the user guide
for your phone, which provides important safety and maintenance information.
Keep the loopset out of reach of small children.

4. To answer or end a call, press the answer button on the
device or use the keys on your phone. Calls can be made in
the normal way (see the user guide of your phone).
Notes
• The lead does not need to be connected to the Pop-Port connector of the
phone all the time. You can choose to connect it only when you wish to make
or receive calls.
• When you receive a call, both the phone and the loopset sound an alert if the
lead is connected to the phone and if the hearing aid is in the T or MT mode.
• To adjust the volume of the loopset, use the volume keys of the phone. For
normal use, keep the volume low, where you can clearly hear your own voice.
In a noisy environment or if the received speech is weak, increase the volume
so that the background noise becomes weaker and the caller’s voice becomes
stronger.
