Checking for Faults
How to check for a fault on your Viscount
If your Viscount fails to work correctly carry out the following
simple checks:
1.
First Check that the handset has been properly replaced.
2.
Ensure the plug is properly inserted into the wall socket.
3.
Check the operating instructions have been followed correctly.
4.
If your phone still fails to work correctly you should follow the
following procedures.
If you cannot make a call from your Phone
There may be no dialling tone for example - disconnect any other
extension phones and try to make a call again on your first phone. If
you succeed in getting through, re-connect your extension phones
until you locate the faulty phone or socket. To establish if it is the
phone that is faulty connect it to a socket where there is
a
phone that
you know is working properly. If the problem continues, the extension
phone is likely to be at fault.
If you cannot make a call with only the first phone connected, you
should report the situation to the British Telecom Fault Service. Their
number is usually
151,
but it may vary locally, check your Dialling
Code Book to be sure. Once you have spoken to an engineer, he will
be able to give you more advice and may do a remote test on your
installation.
