General information
The CM-1 communication system makes it noticeably easier for hearing-impaired
people to take part in conversations in difficult situations.
Each time you switch it on, take care to ensure that the volume on
the CM-1 receiver is set correctly to suit your personal needs in
order to avoid possible damage resulting from excessive volume.
To do this, turn the volume control down low.
The CM-1 communication system contains small parts which can be swallowed and
is not suitable for children under the age of 3.
If the device is not used properly, the manufacturer will not accept any liability for
damage and injury.

Inserting the teleloop into the CM-1 receiver:
The CM-1 receiver can be used in two ways:
•via the teleloop which is supplied
•via a headset (not included in the scope of delivery)
In order to ensure successful transmission via a teleloop, your hearing aid must have an
integrated telecoil (T-coil) with which the sound information is transmitted inductively to
your hearing aid. Hearing aids generally tend to have a small T/MT switch which can be
used to set your hearing aid to inductive reception.
1. Insert the two plugs fully into the jacks on the top of the device. The marking on the
side of the plugs points towards the headset jack.
2. Turn the plugs through 90° so that the markings on the side point towards the top of
the device.

Inserting the battery into the CM-1 receiver:
The device runs on a rechargeable "AAA"-type battery. It can also run on a non-
rechargeable battery.
Where necessary, only use original replacement batteries.
If you run your CM-1 communication system on disposable batteries, don't place the
receiver onto the CM charger.
Ensure that the battery is placed the right way around into the battery
compartment. The stipulated installation direction is indicated on the bot-
tom of the battery compartment.
N.B. This battery is not adequately charged upon delivery and has to be
charged fully on the CM charger first of all.
1. Switch off your CM1 receiver.
2. Remove the battery compartment cover from your CM-1 receiver.
3. Place the supplied battery into the battery compartment (note the polarity!).
4. Place the cover onto the battery compartment.
5. Place the CM-1 receiver into one of the CM chargers.

The CM-1 communication system in everyday use
At a presentation
1. Set your hearing aid to "T" or "MT" in order to transmit sound information directly to
the T-coil in your hearing aid via the teleloop, or connect a headset to a CM-1 receiver.
2. Slide the mode selector switch to the Omni position.
3. Position your CM-1 transmitter as centrally as possible, e.g. on the conference table.
4. Use the fold-out stand to raise the microphone unit somewhat and to mechanically
dampen jolting noises from the surface of the table.
5. Switch the CM-1 transmitter and CM-1 receiver on at the on/off switch.
6. Adjust the transmission volume to a comfortable level by setting the volume controller
on your CM-1 receiver to an appropriate level.
 You are seated in groups around a number of
tables in a presentation room, for example.
Sound is distributed evenly throughout the
room via a loudspeaker system.
Occasional questions are put to the speaker
from people seated at the groups of tables.
Use "Omni" transmision mode.
You can influence the tone of the sound transmitted by varying the tone
pattern on the HI/LO selector switch: the HI position accentuates the
transmission of the treble tones.

36 English
Meeting "around" a table
1. Set your hearing aid to "T" or "MT" in order to transmit sound information directly to
the T-coil in your hearing aid via the teleloop, or connect a headset to a CM-1 receiver.
2. Slide the mode selector switch to the Zoom position.
3. Position your CM-1 transmitter as close as possible to the speaker, whereby the
device's microphone unit should be pointing as directly as possible towards the
speaker.
4. Switch the CM-1 transmitter and CM-1 receiver on at the on/off switch.
5. Adjust the speech volume to a comfortable level by setting the volume controller on
your CM-1 receiver to an appropriate level.
 You are taking part in the meeting shown.
 The other people are speaking at different
levels.
 Use the "Zoom" transmission mode to reduce
disruptive sounds from behind perceptibly and,
at the same time, to amplify speech in front of
you.

English 37
In "direct" dialogue
1. Change the position of your CM-1 transmitter so that it is pointing as directly as
possible towards the other person.
2. Slide the mode selector switch to the Super Zoom position.
3. Adjust the transmission volume to a level which is reasonable for the conversation.
 You are having a more private conversation
with another person.
 You would like to concentrate fully on this
person.
 You are distracted by all the other types of
noise.
 Use "Super Zoom" transmission mode to reduce
all noises from the sides and from behind
perceptibly and to filter out the other person.
On a trip – in a car, in a train compartment or on an airplane
You are on a journey, for instance as part of a travel group on a train or bus, accompa-
nied by someone in the car or traveling alone by air. You want to be able to chat to the
person sitting beside you during the trip, however the person isn't sitting on the same
side as your hearing aid.
The situation is compounded by all the other disruptive sounds on board, especially the
permanent noise from the air-conditioning, in an airplane for example.
Just like having a private conversation at a meeting, you need to amplify all the sounds
made by the other person with the greatest possible concentration.
The CM-1 produces the desired effect in Super Zoom transmission mode by reducing all
noises from the sides and from behind perceptibly and by filtering out the conversation
with the other person.

38 English
Enjoying music or TV programmes
There is an audio input jack on the CM-1 transmitter which you can connect directly to
your television or music system using the supplied audio cable.
How to connect a device:
1. Switch off the CM-1 transmitter and the CM-1 receiver.
2. Set the volume control on the CM-1 receiver to a low value.
3. Insert the two cinch plugs (Ø 3.5mm) into the audio input jack of the CM-1 trans-
mitter.
4. Insert the other two cinch plugs into the audio output jack of your television or music
system.
5. Switch the CM-1 transmitter and the CM-1 receiver back on.
6. Adjust the transmission volume to a comfortable level.
Changing the transmission frequency
If you experience transmission interference, this may be due to the fact that there are
two CM-1 systems being operated in close proximity to one another.
The CM-1 transmitter and CM-1 receiver are capable of communicating in three different
frequency ranges. The frequency ranges are characterized by the letters "A“, "B“ and "C“
and apply to transmitters and receivers alike.
Bear in mind at all times that the CM-1 transmitter and the CM-1
receiver have to be set to the same frequency ranges. Discrepancy in
frequency ranges will prevent any transmission.
1. Switch off the CM-1 transmitter and the CM-1 receiver.
2. Open the battery compartment on your CM-1 receiver and take out the battery.
3. Use the supplied pin to adjust the frequency selector switch inside the battery
compartment.
4. Re-insert the battery and place the cover on the battery compartment.
5. Turn the CM-1 transmitter around so that it is facing away from you.
6. Use the supplied pin to adjust the frequency selector switch on the back of the
CM-1 transmitter to the same value that you had previously selected for your
CM-1 receiver.
7. Switch the CM-1 transmitter and the CM-1 receiver back on.
