The Signal Strength indicator uses bars to
show the intensity of the radio signal. The
number of bars increases as signal
strength increases to a maximum of five
bars.
When the bars are dimmed and the
antenna icon is crossed out, no connection
is possible for one of these reasons:
•
•
•
•
To improve signal strength when you know
there is GSM coverage in your area, try
adjusting the position of the antenna (it
should be vertical), moving near a window,
or otherwise changing the position of your
computer so that the AirCard antenna is
better positioned to receive radio signals
from nearby cellular radio towers.
The In Use indicator shows whether a call is in progress. Depending
on the in-use state, one of these icons is displayed:
When the In Use indicator is a handset, a
voice call is in progress.
When the In Use indicator is a modem, a
circuit mode data (or fax) call is in progress
(see "Dial-Up Circuit Mode Calls" on page
42).
When the In Use indicator is a modem with
packet indicator, a packet mode (GPRS)
data call is in progress. (See "Packet Mode
Connections" on page 43.)
When the In Use indicator is a large "X",
the AirCard is not functioning properly and
no connection is available. (Try closing
Watcher and restarting your computer.)
Meaning
the antenna is retracted
you are outside the GSM network
coverage area
the signal strength is too weak
a network or account problem is
preventing the AirCard 710 from
obtaining service
