Operation Manual
Accept incoming calls and adjust receiving volume 
•  By once pressing the talk button   at your Bluetooth
TM
 headset you can take over a call with your 
wireless headset. Switch-over will always take a short moment. During switch-over you will hear a 
short melody. 
•  Adjust the earphone volume by pressing the volume buttons or of the headset according to 
your wishes. You may also feel the volume keys with your fingers: The key with one dot reduces the 
volume, while the key with 2 dots will increase it. This adjustment will have no effect on the volume 
of the microphone!  This volume is automatically adjusted by the volume of our own voice and the 
integrated DSP (digital signal processor). 
•  After finishing your call do not forget to put back your handheld receiver, otherwise the line might still 
be occupied thus creating unnecessary costs! 
Important advice for transmission range: 
The Bluetooth™ headset has an averange range of about 10m.  This range can be influenced by your 
surroundings. Electronic appliances close to your telephone may reduce range whereas a free area may even 
increase it. 
In case your Bluetooth™ headset has lost connection to your telephone just press the center button   
at your headset to reconnect. In case this does not work, just switch your headset off for a short moment and 
on again before pressing the center button at your headset. 
Pairing between Bluetooth
TM
 Headset and Audio-Gateway 
According to the international Bluetooth
TM
 standards and agreements your  headset ist able to establish a 
reliable and safe audio transmission to a lot of different devices using the Bluetooth
TM
 technology. 
Your headset  comes factory programmed („paired“) and ready for use with the individual audio-gateway 
supplied together as a set. If you  want to connect the headset with other Bluetooth
TM

phone), or if you have already used your headset with another device, you must repeat the pairing procedure 
before reconnection to your audio-gateway.   
In such a pairing procedure, headset and partner device must exchange informations and security data, 
before they can mutually acknowledge themselves as partner units. This procedure, which includes a reset, is 
defined as  „pairing“.  Important:  Only paired devices  can communicate  with each other,  there is no 
comminication possible with a third device at the same time. For pairing with other devices please read the 
last chapter of this manual.
