COURIER HIGH SPEED MODEMS
Double characters
Your modem's online local echo is on and the remote modem is
also echoing. The only way to correct this is to bring the modem
back to Command mode (wait one second without transmitting
data, type+++, wait another second). Then type the command
to turn off your online echo (ATFl <Enter>).
If DIP switch 9 is OFF (factory setting), the modem hangs up
when it returns to Command mode, and you'll have to call again.
If DIP switch 9 is ON, the modem maintains its connection. You
can return it back online by typing A TO <Enter>.
IF YOU STILL HAVE PROBLEMS
The problems described above are by far the most common ones
that users encounter. If the suggestions we've given don't clear up
your difficulties, try the following:
1. Review the manual carefully to see if you've missed
something.
2. Call or visit your dealer. Chances are your dealer will be
able to give you the assistance you need. This is much more
efficient and time-saving than returning the modem to
USRobotics.
3. If your dealer can't clear up your difficulties, call the
USRobotics Technical Support Department at 800-982-5151,
or send a Fax to 708-982-0823. Our Service Representatives
will be happy to give you assistance over the phone Monday
through Friday from 7:30 a.m. to 6:00 p.m. (Central Time
Zone).
4. If necessary, the Service Representative you talk to may give
you a Return Materials Authorization (RMA) number.
Modems without an RMA number will not be accepted.
5. If you do return the modem to us, please use the following
procedures.
a. Ship the unit, postage paid, in its original container. If
the original container is not available, pack the modem
carefully in a strong box of corrugated cardboard with
plenty of packing material.
