INTRODUCTION
Congratulations on purchasing your GeemarcTM LoopHEARTM.
This is a portable induction loop system that can be used in a
variety of locations, both public and private.
This tough but light unit is easily transported and an integral
battery allows it to be freestanding. This battery is both
replaceable and rechargeable and long usage can be expected
(up to 24 hours). The loop is contained within the unit hence
there are no trailing wires. The LoopHEARTM will cover an area
of approximately 1m2 /3.3ft2. There is an integral microphone
that picks up speech and conversations. An external
microphone may be added if required (supplied). This
induction loop system is designed to assist hearing aid users
by transmitting direct to their telecoil equipped hearing aid
(which must be switched to the ‘T’ position).
Note: users of digital hearing aids must make sure their
aids have been programmed for use with the ‘T’ setting.
The outer carton has been specially designed as a handy
carrying case. It is recommended to retain this carrying case to
enable safe transportation when transporting the LoopHEARTM.
It is important that you read the instructions below
in order to use your GeemarcTM LoopHEARTM to its
full potential. Keep this user guide in a safe place
for future reference.
RECOMMENDATION
We recommend that to preserve the environment,
you switch the button on/off to off after each use. The
RED LED indicator will switch off.

USING THE LoopHEARTM
FIXING THE HAND HELD Listener HOLDER
The hand held listener holder can be attached to the
LoopHEARTM on the left hand side or the right hand side,
depending on where it would be convenient for use. In order to
fix the attaches the receiver holder:
1. Insert the lug at the side of the holder gently into the slot in the
cabinet.
2. Insert the screw provided with the holder into the hole of the
holder and into the hole in the side of the cabinet, and tighten
the screw fully using a screw driver.
The handheld receiver can now be placed in the holder.
Note:
The handheld receiver has a built in magnetic sensor which will
ensure that the receiver cuts out when it is replaced in the holder.
10
USING THE LoopHEARTM
Turn the LoopHEARTM On
Turn the power switch found at the rear of the
unit to the 1 position. The power indicator
RED LED next to the switch lights up.
Turn the LoopHEARTM Off
After use, turn off by setting the power switch at the back of the
unit to the 0 position.
INSTALLATION & OPERATION
1. Choose a suitable location, free from
magnetic or electrical interference for
installation and use of LH102. Install
the LH102 ensuring that the cables are
securely anchored.
2. Connect the desktop Microphone to
the Mic jack. (or If needed connect an
Aux device to the Aux input jack).
Please note that if an Aux device is
connected, the MIC will be switched off.
3. Switch on the external power and
check that the Power ON LED
illuminates.
4. Apply the input signal (for example
speaking into the Mic) to Mic or
playing some music on the Aux device.
(For the Aux input the sensitivity can
be adjusted with a small flat blade
screwdriver via the control which need
to be turned until the green LED start
to light).

USING THE LoopHEARTM
5. The LH102 is already factory set to
get optimal performances in magnetic
field transmission but, depending
upon your specific requirements, you
can change the magnetic field level
or its frequency response. Use a
small flat blade screwdriver to adjust
the controls for the Loop Current and
Tone Adjustment.
6. Test the performance of the system
using a loop receiver or field strength
meter. Adjust the Tone and Loop
Current controls to achieve the desired performance.
The Tone adjustment enables compensation for loss of higher
frequency signal during transmission.
Turn the Loop Current control clockwise to get the desired
magnetic field level (The Loop Current Indication LED will
become brighter as the Loop current is increased).
7. Loop Antenna & Performance
The unit has a built in loop antenna which is normally sufficient
for most applications.
However to increase the coverage area, one can use an
external perimeter loop with the following characteristics:
Loop resistance 0.3 to 1 ohm
Loop Impedance 1.3 ohm at 1.6 KHz
For local area loops, use wire 0.5 to 1.5 mm2 or 22 to 16 AWG
The external loop can be connected to the unit at the
connector at the back. Just press the latches of the spring
clamps and insert the terminating wires of the external loop. If
using the external loop, slide the selector switch next to the
connector to the External loop position.

USING THE LoopHEARTM
USING THE LoopHEARTM
Using the Hand held HAC Receiver
A Hand held HAC receiver is supplied for
hearing impaired users who do not use a
hearing aid, do not have a ‘T’ coil hearing aid
or wish extra privacy afforded by the hand
held listener.
Simply, plug the hand held listener into the
RJ9 connector at the rear of the unit.
The receiver has a magnetic sensor which
automatically switches on the receiver
when it is removed from the holder and
switches off when it is replaced.
The volume can be adjusted by using the
volume knob also found at the rear of the unit
(turn knob clockwise to increase volume).
Using the External Microphone
Plug the supplied desktop microphone into the MIC JACK at the
back of unit. The external microphone will now override the builtin microphone. The magnetic field LED indicator will light up blue
when you speak to the built-in microphone or external
microphone.
NOTE: When the external or Internal microphones are in use,
the blue LED light flashes with an intensity depending on the
strength of the transmitted magnetic signal through the loop.
13
USING THE LoopHEARTM
Using the Audio Input
The LoopHEARTM can transmit sound through the loop from an
external audio source like a TV set , MP3-4 , computer.
Connect your audio equipment to the 3.5mm socket
(blue) on rear panel of your LoopHEARTM. You will
then hear the magnetic signal when you are within 1
meter of the LoopHEARTM with your hearing aid in
the “T” position.
The sensitivity can be adjusted by turning the control
at the rear with a small flat screw driver.
LED Indicators
The unit has various LED indicators located in the handle recess
area, which light up as follows :
1. Blue LED flashes in sync with the Field Strength LED on the
front.
2. If the AC adaptor is plugged in
- White LED lights up if the battery is charging.
- White LED changes colour to Green when the battery is fully
charged.
3. If the AC adaptor is not plugged in and the unit is switched ON
- All LEDs except the Blue one will be off if the battery has
adequate charge.
- Red LED lights up when the Battery voltage is low. When the
Red LED lights up Plug in the Power Adaptor immediately to
charge the battery.
14
TROUBLESHOOTING
The RED LED is flashing
• Charge the battery
The LoopHEARTM keeps on switching off
• Make sure that the batteries are fully charged
You cannot hear clearly due to interference or you cannot
hear at all
• Make sure the LoopHEARTM is switched on and facing you
• Move the LoopHEARTM closer to you
• LH102 produces minimum 400mA per meter at a distance of
80cm in compliance with specification EN60118-4. This
produces an effective magnetic field of 2.5M or more
depending on the sensitivity of the hearing aid or listening
device. For example, when used with the Geemarc products
LH10 or LH20 a distance of 3M can be achieved. The
magnetic field strength can be adjusted with the Loop current
potentiometer on LH102 rear panel (see page 12 item 5 in
your user guide) which can in such case also adjust the
distance of detection.
BATTERY USAGE:
To ensure that your LoopHEARTM is always ready for use please
follow the recommendations below:
• Always switch off when not in use
• Always recharge the batteries after continuous use for more
than 6 hours or when the red LED is ON
• Recharge the batteries every four months if the unit has been
switched OFF for long periods of time
As a rough guide the battery will allow the following usage
depending on the volume levels and ambient noise:
• Standby when turned Off 4 MONTHS
• Standby when turned On but not in use 1.5 to 2 DAYS
• In continuous use from fully charged battery 5 to 8 HOURS
