Conference Microphone DC10
One of the Bluetooth connections (telephone, code
0000) has priority. This means that the voice dialling and
re-dialling functions only work in this telephone if two
telephones are connected.
- Voice dialling is activated by briefly pressing (approx.
1/2 second) the answering button.
- Re-dialling is activated by pressing the answering
button approx. 2 seconds.
Microphone position:
During a telephone call, it is possible to select between
the modes Omni – Wide, Omni – Narrow and Zoom,
using the mode selectors on the long side of the unit.
Volume control:
During a telephone call, the volume can be adjusted by
using the menu control on the long side of the unit (this
adjusts the telephone’s volume control). The display
shows the current volume.
When using land line/cordless and mobile phones at the
same time
On some land line/cordless telephones the Bluetooth
connection is not active if no call is being made. This
can cause a time delay before Bluetooth is connected
for an incoming call. In certain cases the time delay can
be avoided by pairing a cordless telephone in the “Pair
Mobile” profile, but this can cause problems with initiat-
ing outgoing calls from the land line/cordless telephone.
For more information, see “More Functions”.
Some mobiles require further adjustments to obtain
sufficiently loud sound. For example increase the level
manually in the media player’s equalizer (SonyEricsson).
Charger unit
The Conference Microphone DC10 is delivered with a
charger unit. Apart from charging the microphone, the
unit can be connected to external sound sources. There
are 2 sockets at the right hand short side of the charger
unit, marked 1 and 2 (look underneath).
At socket 1, an external microphone can be connected.
At socket 2, a stronger signal source, such as TV, MP3,
radio etc. can be connected. It is not possible to use
both sockets at the same time. In that case, an error-
message is shown: Disconnect from Mic/Line. The level
of these signal sources can then be adjusted under
Inputs – Charger unit.
10) Radio range and channels
The transmitter and receiver have built-in antennas.
The radio range between the units is around 100 feet
(30 metres). This may however vary depending on the
particular environment you are in.
Like all radio systems, Comfort Digisystem communi-
cates on specific channels. If you use two transmitters
on the same channel or a neighbouring one, there may
be interference. Other electronic equipment can also
interfere with radio transmissions.
The channel that you use in your country is perhaps not
permitted abroad. Always get in touch with your hearing
aid provider in your country in order to find out which
channels are permitted in different countries.
Comfort Audio is not liable for unauthorized use of radio
waves, such as, but not limited to: interferences with
police communication, or strategic communication,
military installations etc.
11) Trouble shooting
The transmitter and receiver do not start
Charge the transmitter and receiver. Remember to press
the On/Off button down for 2 seconds to switch the unit
on. Check that the charger is connected to the plug
socket.
Poor speech intelligibility
The distance between the transmitter and the receiver
may be too long. The range is around 30 metres. The
distance between the microphone and the person who
is talking may also be too long; move the microphone
nearer to the person talking.
Try to change channel/environment.
Poor range and interference
In some environments involving, e.g., concrete, iron
or sheet metal structures, the range may be reduced.
There may also be equipment nearby causing interfe-
rence. Change channel.
No sound
Check that the transmitter and receiver are set to the
same channel.
Loud hissing noise (no sound transfer)
Check that the units are paired.
The unit will not start during charging
Disconnect the charger. Check the selection Auto power
off under Settings in the menu.
