Meaning
Note: This icon is displayed only when voice and data
services are available.
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 four bars.
Tip: Optimal signal strength is obtained when the
antenna is perpendicular to the card.
When no bars are shown, no connection is possible for one of these 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
PCS Connection Card from obtaining service
Once a connection is established, this icon is replaced by the
Transmit/Receive icon (shown on page 45).
The silent ringer feature is enabled. When an incoming call is received,
no sound is played. You can enable and disable this feature under
> . (Page 76.)
