INTRODUCTION

LoopHEARTM20 is a Personal Sound Amplifier which
can be used by people with impaired hearing or by

people with normal hearinghearing impairment who do
not have “T” coil equiped hearing aids. It amplifies

speech together with sounds from a variety of sources
like TV, radio and telephone.

The LoopHEARTM20 can be used as an alternative to
Hearing Aids. If you use an inductive neck loop instead

of the headset, the built in T-coil in the LH20 enables the
device to act as a compliment to your Hearing Aid.

Note: users of digital Hearing Aids must make sure
their aids have been programmed for use with the “T”
setting.

WARNING: This product can produce high sound

pressure levels in order to assist people with impaired
hearingcan greatly amplify the sound. Excessive sound

pressure levels can cause hearing damage so it is
recommended to initially set the volume to a low level
and gradually increase it to a comfortable level.

AC supply and does not have an integral ON/OFF
switch. To disconnect the power switch the mains
power point switch to OFF or unplug the power supply
(AC-DC adapter);

▪ Clean the headset and ear tips regularly ----- use a

damp cloth for the headset and warm water and a mild

detergent for the ear tips (after removal from the
headset); (for commercial applications spare ear tips

are available for purchase)

heat generating appliances;
