nIntroduction
Please read through user manual carefully before using this device and
store the manual properly after use for future reference.
nApplications
The amplifier EH-101 is used to support hearing-impaired people
in conversations and better like quality. Speech and noise of the
environment will optionally be picked up via the inbuilt microphone
or internal reception coil. The amplified sound will be reproduced
via headphones to the user. Instead of headphones, it will also be
possible to connect an induction loop for transmitting the sound to
hearing aids with a “telephone coil”. An additional input will also allow
connection of an audio unit (e.g. CD player, mp3 player, iPod or a
radio).
nImportant notes
The amplier corresponds to all required directives of the EU and •
USA and is therefore marked with and .
The unit is suitable for indoor use only. Protect it against humidity and•
heat (admissible ambient temperature range 0-40˚C).
For cleaning the housing only use a dry, soft cloth. Never use water or•
chemicals.
No guarantee claims for the amplier and no liability for any resulting •
personal damage or material damage will be accepted if the amplier
is used for other purposes than originally intended, if it is not correctly
operated, or if it is not repaired in an expert way.
If the unit is to be put out of operation denitively, please

If the amplier is not used for a longer period, remove the batteries
to prevent damage to the amplier due to battery leakage.
2. Connecting headphones or an induction loop
Connecting headphones EM-201 to the 3.5 mm jack (1).
Alternatively, connect the induction loop NL-90 to the jack.
The loop is placed around your neck and will transmit the sound
via a magnetic eld to hearing aids with a “telephone coil”.
3. Connecting other audio sources
The 3.5 mm jack AUX will allow connection of an audio unit
with line output level (e.g. CD player, radio or the audio output
of a TV set). Thus, the microphone will be switched off.

Stereo plug
Mono plug
Connect to CD/MP3/
iPod/Audio/TV or
other sound source.
When being plugged in, it
can only receive AUX sound
source, thus, the microphone
will be switched off.

4. Operating internal induction loop
1) To activate internal induction loop, please set the MIC/LOOP
button to the LOOP mode (MIC/LOOP button display in green).
2) Internal induction loop gets better results in areas with
induction loop system built-in, such as church, and theater.
3) When internal induction loop has been activated, you can hear
voice directly.
4) The icon on the right or similar icons to the
right indicates induction loop system is built-
in. You could also install induction loop
system at place you desired like shown under.
(For more information, please contact the seller
you purchase this product from.)
5) When internal induction loop has been activated,
microphone function will be switched off automatically,
therefore, you won’t hear any background noise.

5. Operation
1) Switch on the amplier with the volume control (6); turn the
rotary control downwards so it will just unlock.
2) For operation with headphones, select the audio source with the
button MIC/LOOP (5): For the microphone or an audio source
connected, disengage the button (button dimly lit in red). For
reception via the internal coil (for operation at inductive sound
reproduction systems), engage the button (button dimly lit in
green).
3) Place the lanyard (2) with the amplier around your neck or put
it on a table so that the side with the microphone (3) will point
to the person you are listening to. For optimum reception via
the coil, hold or wear the amplier in a vertical position.
4) When using induction loop mode, please place the device
vertically to maximize the performance.
5) Adjust the desired volume with the control (6). If there is no
sound, the batteries may be exhausted.
6) To prevent unnecessary battery consumption, switch off the
amplier after use. For this purpose, turn the control (6)
upwards until it locks.

nAdvance settings
Switches inside battery compartment can use for the
following setting:
1. Amplication level increase
If volume is too low even if the control (6) is tuned up considerably,
switch 1 will additionally increase the amplication.
2. Switching off the bass attenuation
To improve speech intelligibility and to prevent hum interference
when receiving sound via the internal coil, a high-pass lter is
integrated to attenuate low frequencies. If low frequencies are
desired, e.g. when listening to music, switch off the lter with
switch 2.
3. Restricting the selection of audio sources
If the audio source is not to be switched over with the button
MIC/LOOP (5), dene the operating mode with the switch 3 and 4.
