3-5. Adjusting the volume:
8 volume levels can be set with the control wheel button. To do this, turn
the wheel up or down. Each volume level is indicated by a beep, a double
beep means that the maximum setting has been reached.
The volume can be changed at any time. Exceptions: The receiver is in
pairing mode or the battery level indicator is lit.
Please note that the volume setting applies to both event indicators.
3-6. In case of device conflicts:
If the »visuTone.air« behaves erratically or rings for no apparent reason,
there may be an interference caused by a neighbouring RF device. This
can be resolved by changing the transmitter code as follows:
1) Unregister the affected transmitter as described in 3-3.
2) Remove the button cell battery from the affected transmitter.
3) Press and hold the transmitter button and reinsert the button cell.
The button should then be held for another 5 seconds. The transmitter's
LED flashes 5 times, indicating that a new coding has been generated.
4) Now register the transmitter again.
