LCD area of the
Watcher window.
a. You have an account
problem or the network is
overloaded with calls.
b. The phone number is incor-
rectly set up in the Dial-Up
Manager.
a. Determine whether the problem is
due to an AirCard / Dial-Up Manager
setup issue or an account / network
issue by making a call to a local
number. If you are able to complete
this call, the problem is likely in the
way that the connection is set up.
Otherwise, contact your service
provider.
b. Verify that the number you want to dial
is set up properly in the Dial-Up
Manager. See page 144 for instruc-
tions on using the Dial-Up Manager.
Verify that the phone number is
entered correctly, and that the Use 1
and Use Area Code check boxes are
appropriately set. If the area code is
required, ensure it is entered correctly.
