Introduction

Univox® Loop Listener is a useful loop receiver and a

small, user friendly testing device. Listener can be used

as a receiver to listen to the induction loop system,

either through the built-in speaker or through separate

headphones. As a testing device Listener can check that

the system works and verify the basic signal strength

according to the international standard IEC 60118-4.

Thank you for chosing a Univox product. We hope that you

will be satisﬁed!

Use Listener as a loop

receiver

Turn on Listener with the on/oﬀ switch. When Listener

is on, the red LED on the front is ﬂashing. The sound can

either be heard through the built-in speaker or using

separate headphones or an earphone with 3.5 mm

stereo plug which is connected to the outlet at the

bottom.

Put the neck strap around your neck and make sure

Listener is hanging vertically all the time. Adjust the

volume with the volume control wheel on the right side

and the treble/bass with the tone control wheel on the

le side. Hanging around the neck on a person of normal

height, Listener will be approximately 120 cm above

the ﬂoor, i.e. at the same height as the hearing aid on a

seated person, making it easy to walk around the looped

area and listen to the sound of the loop.

Use Listener as a testing

device

Turn on Listener using the on/oﬀ switch. When Listener

is on, the red LED on the front is ﬂashing.

Yellow light indicates -6 dB (re 400 mA/m) and green

indicates 0 dB. If the green light is ﬂashing the ﬁeld

strength level meets the international IEC standard.

A yellow light indicates that the loop is working but

the ﬁeld strength level does not meet the IEC-standard

requirement.

To measure the magnetic ﬁeld strength levels more

exactly and to carry out other important measurements

(for example background noise and frequency

distribution) a professional measuring instrument, like

the Univox FSM 2.0 has to be used.

It may be diﬃcult to monitor the LED if wearing the

Listener around the neck by the strap. We therefore

recommend to hold the Listener in front of you at the

height where you want to check the ﬁeld strength.

A hearing aid is approximately located 120 cm above the

ﬂoor when the user is seated. For standing height, hold

Listener 160-170 cm above the ﬂoor.

Note!

Hold Listener in a straight vertical position to receive the

signal at full strength. If Listener is tilted, its ability to

receipe the signal will decrease.

Warranty

Please note that warranty is not valid for any damage or

defects due to incorrect or incautious usage.

Maintenance and care

Under normal circumstances the product does not need

maintenance.

Should the unit become dirty, wipe it with a slightly

damp cloth. Do not use solvents or heavy cleaning

agents.

Troubleshooting and service

Make sure that Listener is turned on (red LED ﬂashes). If

the red LED does not start ﬂashing, make sure that the

batteries are correctly inserted and are working properly.

If the batteries are not working, please replace them

with new.

If the loop receiver sound is weak, make sure that

Listener is hanging/held in a vertical position. Adjust the

volume if necessary. A weak signal might indicate that

the loop system does not comply with the international

standard IEC 60118-4. Check the level using LED

indicators. Yellow veriﬁes correct function but does not

comply with the standard.

Should the product not work aer having made the tests

as described above, please contact the local distributor

of the product for further instructions. Please attach

error description, name, address, telephone number and

receipt or invoice.
