Troubleshooting
Check that the telephone cord is undamaged and properly plugged in.
Disconnect any additional equipment, extension cords and other telephones
that may be connected. If the problem is resolved, the fault is with the other
equipment.
Test the equipment on a known working line. If the product works then the
fault is with the line. Please inform your local telephone company.
