• Handset is no longer registered with
the base station – someone may have
de-registered it. To register handsets
see your System Set-Up Guide.
• Handset may be out of range of the
base it is registered with. Move the
handset nearer the base.
• The base may be switched off or has
no power due to:
a) The mains power adaptor cable
may not be connected to the base.
b) the mains power adaptor may not
be plugged into the mains socket.
c) The mains power may not be
switched on.(However, an attached
telephone on 0 should still work)
• If the handset is registered with more
than one base it may be set to manually
select a base which is not the one you
want it to connect to.
Please note.
If you go out of range of the Diverse
ISDN for a long time while your
handset is switched on, it may take
more than 20 minutes to ‘find’ it again
when you come back within range.
However, simply by switching the
handset OFF for a moment then ON
again, it will find the Diverse ISDN
within a few seconds.
Extension does not get external dial
tone
This could be due to any of the
following:
• The Diverse ISDN telephone line cord
may not be plugged into the ISDN
socket.
• If the handset display shows
EXTERNAL
LINE BUSY
, all available external lines
are in use by other users. Wait until
the calls are finished and try again.
• Call restrictions (barring) may have
been set at the base station to prevent
the extension from making calls to
certain, specified numbers see your
System Set-Up Guide.
• You may be pausing too long between
pressing the buttons. The system will
time out if you pause for more than a
few seconds.
• Automatic external line may be
switched off for the extension and you
are forgetting to include the line
access code
EXT
or
0
when you dial
(see your System Set-Up Guide).
Handset display shows FAULT
This could be due to either of the
following:
• The ISDN cable may not be connected.
Check that the cable is plugged in
properly.
• The ISDN line may be defective and
you will have to ring your ISDN
service provider.
