This section contains information on how to solve common
operational problems.
Go through the following steps if you 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.
1. Make sure your telephone is connected to an
analogue line
2. Read the Installation chapter
To make sure that you have done everything correctly
and that everything is properly connected.
3. Disconnect all extra equipment
If your telephone is working properly when done, the
problem lies in the extra equipment.
4. 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.
5. 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.
