Each time Watcher launches, it launches in Full Mode view. In Full Mode view all menus, indicators,

and buttons are displayed.

The window contains:

• The indicator area which contains icons showing your signal strength, coverage, and

roaming status.

• Action buttons to connect and disconnect, links to customization menus, a digital help

guide, and a shortcut that closes Full Mode view and enables System Tray Mode.

In the alternate view, System Tray Mode, Watcher remains running in the background but no window is

displayed. This feature provides the option of keeping your desktop clear of multiple windows.

Indicator area and icons

Depending on the AirCard 580’s operating status, various icons are displayed in the Indicator Area.

Icon Meaning

The Signal Strength icon displays when Watcher is turned on. The bars indicate the strength

of the radio signal. Four bars signify that the signal strength is at its maximum peak. The

strength will change depending on where you are.

This displays when no signal is available or when the AirCard 580 is powered off. The

antenna symbol is red and the bars are dimmed. When this occurs, no connection is

possible for one of the following reasons:

• No antenna is attached

• You are outside the CDMA network coverage area

• The signal strength is too weak

• A network or account problem is preventing the AirCard 580 from obtaining service

The Service Indicator icons display which network service is currently available at your

location (3G - 1xEV-DO and 1xRTT or 2G)

1xEV-DO service is the default connection. This icon displays “3G 1x EVDO” and

communicates that the 1xEV-DO network is available. Watcher defaults to the best

available network connection once connected. (For example: if all three connection types

are available, Watcher selects the 1xEV-DO connection first, by default, because it is the

premier service).

The “3G 1xRTT” icon signifies that because the 1xEV-DO network is currently unavailable,

Watcher establishes a session with the next best network connection available (1xRTT).

The “2G” icon signifies that only the 2G network is available. The “3G 1xEVDO” icon

becomes dimmed and 3G changes to read 2G.

The icon is “off” (dimmed) when no service is available.
