encounter any problems. If this does not solve the problem,
contact your system administrator. If others have similar
problems, there may be a system error.

Fault check list

1. Read the Installation chapter.
To make sure that you have done everything correctly and that
everything is properly connected.
2. Disconnect all extra equipment.
If your telephone is working properly when done, the problem
lies in the extra equipment.
3. Connect a functioning telephone instead of the faulty
one.
If that telephone is working properly, the problem is probably in
your telephone, contact your system administrator.
4. Check for operational problems.
If operational problems are found, the problem is in the
telephone network, contact the local telephone service or the
local telephone company.
5. Reboot the telephone.
Press and hold for at least one second.
