Error 680 |
The modem cannot detect the dial tone.
First check that there is a dial tone on the phone line by getting the user
to see can they make a voice call over the same line. See do they hear a dial
tone. If they are dialling through a PABX system try putting a few commas after
the 9 or 0 that they use to get an outside line.
This often happens if the modem is not connected properly to the phone
socket. Make sure that the user has put the phone line in the correct socket in
the back of the modem.
