1. Product information
1.1 modeX system
modeX is a wireless communication system, which is suitable for many different situa-
tions such as when teaching hard-of-hearing students. The system comprises different
types of radio transmitters and receivers, which can be combined in different ways.
modeX is compatible with our earlier school system (the 904 system) and corresponding
products from other manufacturers. It is therefore easy to add just what you need to an
existing system.
The modeX system can be used both with a fixed inductive loop and together with
hearing instruments with FM receivers.
1.2 modeX Transmitter
modeX Transmitter is a stationary transmitter which, when connected to other sound
sources (for example other modeX products), relays this information wirelessly to, for
example, a hearing instrument with FM receiver.

2. Installation
2.1 Location
modeX Transmitter can either be placed on a level surface or screwed onto the wall.
Place modeX Transmitter approximately 2-3 metres away from the receivers to minimise
the risk of interference. If more than one modeX Transmitter/Receiver is used, they can
be mounted one above the other (3 Rec./Tra. max.) both when placed on a table and
when mounted on a wall. In this case use our dipole antenna fitted to a 10 metre coaxial
cable to minimise the risk of interference. Remove the rubber feet so that the Transmitter/
Receiver units lie flush against one another.

3. Setting the transmitter
3.1 Programming
Set the locking button (11) to Off. Press the Set button (5) to access the programming
menu.
Programming buttons
Set • Takes you to the next level.
• Saves your settings.
Back • Takes you back a level.
• Quits programming mode.
Up/Down • Increases/reduces a value.
3.2 Programming modes
There are five different programming modes: Channel, Deviation, Line Level, On/Off
key and Power.
Channel
Select channel: There are 106 pre-programmed channels to choose from. These are
channels 20-99 which correspond to other channels in the modeX system. In addition,
there are 19 H, J and N channels specifically for Phonak frequencies and 7 S channels
specifically for Solaris frequencies. All channels can be received by modeX Receiver even
if the frequency does not match precisely. Channels 00-19 do not have a pre-programmed
frequency and can be adjusted as required, see below.
Change frequency: You can change channels 00-19 to any frequency. These channels
do not work if no frequency value is selected. Hold in the button to step through more
rapidly. The frequency steps through 25 kHz for each rapid press of the Up or Down
button.
IMPORTANT When you have selected a setting, you must press Set to save it.

ENGLISH
Deviation
Select here whether to transmit with a 5 or 15 kHz deviation. The default setting is 5, for
the use of miniature receivers on hearing instruments.
Line Level
The sensitivity can be adjusted +/- 15 dB. Preset: 0 dB.
On/Off key
In Active Mode you can switch the transmitter on/off by pressing the Up button. In
Disabled Mode the Up button is locked.
Power
The output power can be set in mode Low or Normal. Low is selected when the range
should be decreased because of several adjacent systems.

4. Troubleshooting
Type of
fault
Problem Action
No sound from
the receiver. 1. Is the correct channel set?
2. Is the modeX Transmitter diode off?
3. Is the Line In cable connected to the
rear of the modeX Transmitter?
4. Is the deviation set correctly (often 5
kHz on hearing instrument receivers)?
1. Check the channel setting. See section
3.2, Channel.
2. Insert the power supply unit. Switch on
the Transmitter (Up button).
3. Insert the Line In cable, in accordance
with section 2.2 Connection.
4. See section 3.2, Deviation.
The sound quality
is poor in the
receiver.
1. Is the modeX Transmitter deviation set
to the same value as the receiver?
2. Are nearby channels causing interfe-
rence?
3. Is the modeX Transmitter RF Output
(transmitter power) set too low for the
receiver?
4. Is modeX Transmitter too close to
modeX Receiver?
1. See receiver user manual.
2. Check the channel setting. See section
3.2, Channel.
3. See receiver user manual.
4. Move the Transmitter further away or
use a dipole antenna.
The sound is weak
when I speak into
the microphone.
1. Is the volume on the receiver set
correctly?
2. Is the Line level on the Transmitter set
correctly?
1. See receiver user manual.
2. See section 3.2, Line level.
5. Care and safety
Cleaning and maintenance
Vacuum the outside of modeX Transmitter with a soft brush. Wipe the outside with a damp cloth. Never use
cleaning products or solvents. From time to time check that the cords and connections are intact.
Repairs
If your product malfunctions, it must be repaired by a qualified technician. Do not attempt to open the case
of the device since this would invalidate the warranty. If your product requires service, please contact your
hearing care professional for assistance.
Waste disposal
