Action
• Call the Net Service

some time and try again.
• Call another destination
(another country).
• Select another Ocean
Region.
• Check that the correct Net
service provider is shown in
the display.
• The FELCOM 70 terminal is
not properly commissioned.
Check with the Net Service
Provider or verily that
"Network status information"
function displays Region
Registration: Successful.
• Connect a PC to FELCOM
70 and read/print out the
traffic log to allow further
logging.
• Remember to press "#" as
last digit before starting
transmission.
• Instead of "#", try to enter:
902 + 00 + country code +
subscriber number.
• See problem 5.
• The OFF-HOOK time should
be as long as possible (e.g.
2 minutes). When the fax
machine is called, ringing
time should be set to
minimum (e.g. immediate
answer).
• Try a different fax machine.
Check that a Group 4 fax is
used on the ISDN interface,
and Group 3 fax via
analogue interface. (e.g.
TEL4).
