Troubleshooting
Under certain circumstances it cannot be excluded totally that current supply interruptions or interferences
may perhaps have influence on the correct functions of the set. In case of a malfunction you may re-establish
the connection by this simple test procedure in exactly the following sequence:
• Switch off the audio-gateway by unplugging the DC power cable from audio-gateway
• Switch off Bluetooth
TM
headset, too
• Insert power cable again into audio-gateway
• Switch on Bluetooth
TM
headset again
After a short moment both units should be paired again together.
If the above described method does not help, a „general reset“ back to the factory default settings may help.
This general reset is also necessary in all cases, where the headset has been used in connection with other
Bluetooth
TM
devices and shall now be re-connected to your individual audio-gateway. The general reset
procedure includes pairing and resetting both partner units (headset and audio-gateway), otherwise they
cannot establish a secure transmission system.
Starting general reset
Please follow the instructions in exactly the described sequence!
• (1) Switch your headset OFF with power switch (slide switch).
• (2) Switch headset ON again
• (3) Press all 3 keys at headset simultaneously at the same time and keep them pressed for
about 3 seconds. Hold headset during that procesure close to your ears. You will hear s short
melody marking a successful reset. If you do not hear the melody within 1-2 seconds, the reset
was not successful and you should repeat steps (1) to (3).

• Place the headset close to the audio gateway.
• Press and hold the TEST/PAIRING button on top side of the audio-gateway and keep button

some seconds until the pairing process will be finished.
