1. modeX system
modeX is a wireless communication system used, for example, when
teaching hard-of-hearing students. The system is compatible with our
earlier school system (the 904 system) and corresponding products
from other manufacturers. modeX works with an inductive loop and
with FM hearing instruments.
With inductive loop: There are two different types of microphones
with transmitters, one for the teacher (modeX Teacher) and one for
the students (modeX Student). The sound from the microphone is
transmitted wirelessly to the fixed modeX Receiver. From there the
sound is passed to a loop amplifier (e.g. Transett 32) and on to the
inductive loop. The teacher’s microphone uses one frequency and the
student microphones use another one. One student can speak at a time.
With FM hearing instruments: As above, but the loop amplifier is replaced
or supplemented by an FM transmitter (modeX Transmitter). If only
one microphone is used, it can transmit the sound directly to the
hearing instrument’s FM receiver.

2. Preparing for use
2.1 Mounting the battery charger (Charger, modeX T/S)
Several chargers can be connected and powered by the same power
supply unit (purchased separately, see Accessories). The chargers can be
placed on a table or suspended on the wall.
Charger
(Charger modeX Teacher/
Student):
Used as a charger for the teacher
and student microphones. The mi-
crophones are charged overnight.
Do not use alkaline batteries.

2.2 Charging the teacher and student microphones
First use – for best battery performance
Make sure that the battery is fully charged the first time it is used.
Charging the battery
The charging time depends
on how discharged the battery
is. A discharged battery takes
12 hours to charge fully. The
microphones can be left in the
chargers even when they are
fully charged. The charging
current is automatically
adjusted for the best battery
performance. The microphone
is switched off automatically
during charging.
Battery level indicator
When the battery is becoming flat the LED on the microphone lights
up/blinks red. A battery level indication is also given in the display.
Natural discharging
If the microphone is not used and is not kept in the battery charger,
the battery may discharge completely after about 30 days (this is
normal). Always keep the microphone in the charger to prevent it from
discharging.

ENGLISH
2.4 Programming the teacher and student microphones
Before the microphones can be put into operation, the channel (Channel)
must be set. The modulation level (Deviation), microphone sensitivity
(Mic Sensitivity) and read-aloud function (Speech key) can also be set.
Programming modes
A) Channel
The microphone and receivers must be set to the same channel so that
they can communicate. Channels close together can interfere with one
another.
Select channel: There are 80 pre-programmed channels to choose between
on channels 20-99. Channels 00-19 do not have a pre-programmed
frequency and can be adjusted as required (see “Change frequency” below).
Select frequency: You can change channels 00-19 to any frequency (in
25 kHz increments). These channels do not work if no frequency value
is selected.
B) Deviation (modulation level)
The deviation can be set to 5 or 15 kHz. The default setting is 15 Hz.
This deviation provides the best sound quality but the risk that dif-
ferent channels will interfere with one another increases with greater
deviation.
NOTE: The deviation for the microphones should be the same as the
deviation for the receiver(s), otherwise the sound received will be dis-
torted. Many hearing instruments with FM receivers have a deviation
of 5 kHz. If the microphones have a higher deviation than the FM
receivers, distortion may be produced.

9
ENGLISH
C) Mic Sensitivity (microphone sensitivity)
The sensitivity does not normally need to be adjusted. But if a person
speaks very loudly or softly, this can be compensated for by reducing or
increasing the microphone sensitivity. The preset value is 0, and it can
be adjusted from -12 to +12 dB. Access the Mic Sensitivity program-
ming mode. Speak into the microphone. Adjust the sensitivity until
the green LED lights up and occasionally blinks red. If the LED is
completely red, the sensitivity should be reduced.
D) Speech key (read-aloud function, modeX Student only)
When the Speech key is activated in programming mode, the student
microphone can be switched on without needing to hold in the push-
to-talk button (see page 11).
E) Side keys (three different function modes for the Up/Down buttons,
only modeX Teacher)
Normal: The Up/Down buttons have no function. This is default.
Speech key: The Up button turns the microphone on. The Down
button turns the microphone off. The function of the blue button is
deactivated.
Volume: The Up button increases the volume of the microphone (the
mic sensitivity) with 3 dB for each press. The down buttton decreases
the volume with 3 dB for each press. The default value is 0 dB. You
can increase and decrease the volume respectively with maximum
6 dB. If the microphone is already set on +12 dB or -12 dB in Mic
Sensitivity, it is not possible to get past these limits with the Up/Down
button.

3. Using the teacher and student microphones
3.1 How to wear the microphones
Teacher’s microphone:
• Can be worn in the pocket/belt together with an external microphone.
• Can be fastened to the top/shirt with a clip (near the mouth).
• Can also be worn round the neck using a neck loop.
NOTE: Do not use the Teacher microphone without antenna/headset
since it will decrease battery time to around three hours.
3.2 Switching on the microphone/speaking
Teacher’s microphone:
Switch on: Gently press the On/Off button. Switch off: Hold in the
On/Off button for about 1 second. The LED goes out.
NB! Check if the function Speech Key is Active (see section 2.4 E).
Student microphone:
Speak: Hold in the On/Off button while speaking. The LED comes
on. One student can speak at a time.
Read-aloud function (Speech key): Activated in programming mode
and means that the student microphone can be switched on without
holding in the On/Off button, e.g. when reading aloud. The button
is then used to switch the microphone on and off. The On/Off button
works as normal.
Built-in antenna: The student microphone has a built-in antenna for
maximum comfort and user friendliness. If interference occurs with
the built-in antenna, this may be due to poor radio reception condi-
tions or the receiver sensitivity may be inadequate. To minimise this
interference, use the external wire antenna supplied.
Student microphone:
• Place it in the table stand for quick and easy access.

1. modeX-systemet
modeX er et trådløst kommunikationssystem til f.eks. undervisning af
hørehæmmede. Systemet er kompatibelt med vores tidligere skolesy-
stem (904-systemet) og tilsvarende produkter fra andre producenter.
modeX fungerer både med teleslynge og med FM-høreapparater.
Med teleslynge: Der findes to forskellige typer mikrofoner med sender,
en til læreren (modeX Teacher) og en til eleverne (modeX Student).
Lyden fra mikrofonen overføres trådløst til den stationære modtager
modeX Receiver. Derfra går lyden til en slyngeforstærker (f.eks.
Transett 32) og videre ud i teleslyngen. Lærermikrofonen benytter én
frekvens og elevmikrofonerne en anden. Én elev kan tale ad gangen.
Med FM-høreapparater: Som ovenfor, men slyngeforstærkeren udskiftes
eller suppleres med en FM-sender (modeX Transmitter). Hvis der kun
benyttes en mikrofon, kan denne sende lyden direkte til høreappara-
tets FM-modtager.
