Watcher displays the
message, “Not in

area of the Watcher
window and the
antenna icon is
crossed out.
Inadequate signal strength may
occur for any of these reasons:
a. You are outside the network
coverage area.
b. Your antenna is not attached
or is pointed in the wrong
direction.
c. You may be inside a building
or near a structure that is
causing radio interference.
a. Ensure your antenna is properly
attached.

area of your service provider.
Coverage maps are available from the
Sierra Wireless web site,
www.sierrawireless.com.

When attempting a
dial-up data
connection, Watcher
displays the
message, “There is
no answer” in the
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 153 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.
Pocket PCs only:
When you have an
AirCard 300 and
AirCard 555 in your
dual-card PCMCIA
jacket accessory,
the data connection
seems quite slow.
If both AirCards are inserted, then
the path that the IP (Internet
Protocol) traffic will take is not
predictable. If the data gets routed
through the AirCard 300, you will
experience slower data transfer
rates.
a. Eject the AirCard 300 from your
PCMCIA jacket accessory before
you use the AirCard 555.
