Troubleshooting
Check that the telephone cord is undamaged and properly
plugged in. Disconnect any additional equipment, extension
cords and other phones. If the problem is resolved, the fault is
with some other equipment.
Test the equipment on a known working line (e.g. at a
neighbour's house). If the equipment works there the fault is
probably with your telephone line. Please inform your network
operator.
If you are still experiencing difficulties, contact the place of
purchase.
