WARNING:
To check the power cord on the control unit as instructed in the following
procedure, avoid standing on a box or chair to reach the unit if it is out of
easy reach. If you do not have a stable ladder or other proper equipment, do
not proceed; wait for the Lucent Technologies technician.
What to do: Make sure the control unit's power cord is plugged securely into the
wall outlet. Also, if convenient and safe to do so, make sure the other end of the
power cord is securely connected to the power supply in the control unit.
If all phones now have dial tone and lights, you have solved the problem.
If all phones are still dead, go to Possible Cause 2.
Possible Cause 2: The power outlet to which the control unit is plugged in is
faulty.
What to do: Test the outlet by plugging in an appliance that you know is working,
for example, a lamp or radio.
If the appliance does not work, the outlet is faulty. If possible, plug the
control unit into a different outlet. Check the circuit breaker or call an
electrician.
If the appliance works, the wiring may be faulty elsewhere in the system.
