Konftel 60W is a conference unit for connecting to existing fixed system tele-
phones, DECT telephones, mobile phones or computers, with a cable or wireless
connection via Bluetooth. Konftel 60W has a omnidirectional, highly-sensitive
microphone and three speakers which, together with Konftel’s OmniSound® provide
optimal sound quality and maximum reduction of room echo, even when the person
speaking is standing at a slight distance from the unit.
Konftel 60W has five buttons. The most common functions for power, speaker
volume and mute are obvious, but all the buttons have other functions for activat-
ing various special functions and settings. Therefore, you should read the sections
of the handbook that deal with the connections you intend to use so that you do
not miss any important options.

Konftel 60W is designed to handle headset and handsfree profiles as per Bluetooth
standard 1.1. Please note that not all telephones support all functions. More
information is contained in your telephone handbook.
If the GSM network has reduced functionality, e.g. due to poor coverage, the sound
quality may be affected. This is not due to the Konftel 60W.

General information on Bluetooth
In order for two Bluetooth units to be able to communicate with each other, they
must first be “paired”, which means that the second unit is added to a list of
added units. Your Bluetooth telephone has a menu where added units are displayed
and where you can, for instance, choose between various Bluetooth headset and
handsfree options.
Familiarise yourself with your telephone’s functions by reading through this hand-
book. In the instructions below, we do not deal with how to use your telephone as
this varies between various makes and models.
Please note!
The Bluetooth protocol, which is used by the units to communicate, has a number
of commands to activate functions, end calls, etc. Some do not function fully on all
telephones. You should therefore check, for instance, that the telephone has actu-
ally disconnected the call if you do this by pressing a button on Konftel 60W.
Bluetooth has a range of up to ten metres. The best performance is achieved when
the distance does not exceed five metres.
4
USING BLUETOOTH
Adding your telephone and retaining other
stored telephones
Konftel 60W can store up to eight telephones. If you
want to retain previous pairings and add a new one,
follow the instructions below. If you want to remove a
previous pairing, go to the next section.
If you store a ninth telephone, the telephone first
stored is automatically deleted.
Please note that Konftel 60W should not be switched
on when pairing.
Press and hold the + and trim buttons for 2
seconds until the blue LEDs start flashing.
and
2 sec
Follow the instructions in your telephone handbook
to add a new Bluetooth unit.
Select Konftel 60W from the list of units detected.
Enter the password 0000.
If the pairing was successful, a short audible signal
will be heard and the LEDs will stop flashing.
Please note that Konftel 60W is normally added as
a headset. This will not work for certain telephones
(Konftel 60W is not displayed as an available
Bluetooth unit on the telephone). You can then choose
instead to add Konftel 60W as a handsfree unit by
pressing and holding the button for 4 seconds instead
of 2 in the display. The blue LEDs then start flashing
more slowly.

Adjust the speaker volume in Windows
Click on the Volume... button under Sound play-
back on the tab Audio.
Adjust the sound level for Volume Control so that

This setting adjusts the line output level from the
computer. A low sound level here means that you
must increase the volume on Konftel 60W to the
maximum level, which may lead to fuzzy sound and
a low sound level. A high sound level means that the
volume on Konftel 60W can be set to an intermediate
setting and still produce excellent sound through the
speakers.
Check the sound level when you playback sounds
(any sound source in the computer). Please note
that Konftel 60W must be switched on.
Note that you also have separate volume controls for
various sound sources in the computer. These volume
controls apply to playback from each sound source.
Choose Mute for microphone input if you do not want
to hear your own voice through the speakers. A high
volume may cause echoes and feedback.
