You can connect or pair additional devices to the hands-free kit in the same manner. The pairing begins for each
device with the hands-free kit switched off as described above.
The hands-free kit then has several "known" devices. This status is a prerequisite for an active connection between the
hands-free kit and other devices. A maximum of 8 devices can be saved as "known devices". As soon as a ninth device
is paired, the oldest device is deleted.
The number of devices that can be actively connected to the hands-free kit is limited to two. As soon as one or two of
the known devices are in the vicinity of the hands-free kit, the connection to these devices is established automatically.

You may need to confirm the connection on your mobile phone. If a third known device now comes in the vicinity of
the hands-free kit, the connection to it is blocked until one of the two active connections is interrupted or one of the two
devices leaves the transmission range. If one of the two active connected devices is no longer paired, pairing is
possible for the third (waiting) device.
The pairing process can take up to 30 seconds depending on the mobile phone which is used.
If two devices are connected to the hands-free kit, different ring tones will be used for incoming calls.
Making calls

connection is established. Answer the call by briefly pressing the multifunction button (2). Once the telephone
connection is established, the LED indicator (4) flashes blue once followed by a long pause. If the
multifunction button (2) is pressed for approx. two seconds, the call can be transferred to the mobile phone.
The call can then also be subsequently retrieved in the same manner.
To reject the call, press the multifunction button (2) for approx. 2 seconds until a beep sounds.
