Help

If the telephone appears to be faulty when fi rst 
connected, a few simple checks may help to identify 
some possible problems, as listed below:

NO DIAL TONE

The handset is plugged into the handset socket 
not headset socket.
Check that the telephone plug is fully inserted in 
the socket.
If it is, try connecting the telephone into another 
socket, if available. If dial tone is now heard, the 
original socket is faulty.
Alternatively, try connecting another telephone 
into your socket. If this telephone gives dial tone, 
then your new telephone is probably faulty.

ALL OPERATIONS SEEM SATISFACTORY 
EXCEPT THE TRANSFER BUTTON

Change the recall selector switch setting (T/E). 
If the transfer operation is now satisfactory, the 
problem is resolved.

For help with voicemail, call divert and call pickup 
please contact your Telecom Team/Provider as this 
will vary depending upon what switchboard you are 
connected to.
