The Call Status Area displays messages related to the status or 
progress of a connection.

Where a duration timer is shown, timing begins when the call 
is initiated—not from the time the call is fully connected. This 
is a measure of the time the AirCard has been using the radio 
channel (a wireless network resource).

“

Click this display to exit PowerSave mode

” indicates that the 

AirCard could not find a 

 system within a 15 minute 

interval. To conserve power, the AirCard reduces channel 
scanning to once every three minutes. To force the AirCard out 
of PowerSave mode, click in the Call Status Area. The AirCard 
performs a channel scan and, if no network is detected, returns 
to PowerSave mode.

The In Use indicator shows whether a call is in progress. No icon is displayed when the 

AirCard is idle. Otherwise, one of these icons is displayed:

A voice call is in progress.

A circuit switched data call is in progress.

A high-speed (1X) packet data call is in progress.

A high-speed (1X) packet data connection is 

; the radio channel 

has been released allowing you to make and receive voice calls. You 

can resume data transmission (when not in a voice call) without the 

need of re-establishing the connection.

Some applications may not be able to function on a 

connection.

A fatal error has occurred and the AirCard is inoperable. (This may be 

resolved by closing Watcher and restarting your PC.)
