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.
4. Troubleshooting
4-1. A red indicator flashes and the ringtone volume has dropped:
Replace the batteries of the receiver. Use „C" (R14) size alkaline batte-
ries.
4-2. An event indicator flashes every 15 seconds:
Replace the battery (button cell type CR2032) of the corresponding
transmitter.
4-3. I need to unregister a transmitter:
Proceed as described in section 3-3.
4-4. The receiver rings but no-one is at the door or the phone:
Proceed as described under point 3-6.

There is a locking tab on one of the narrow sides of the bracket. This must
be pressed slightly away from the transmitter - the transmitter can now be
twisted and removed.
