Using the Phone

Reading the Indicators

Signal Strength Indicator (1)
The Signal Strength Indicator (SSI) indicates the
strength of your phone’s connection with the local
cellular system. A strong signal increases your
chances of placing and receiving calls. Weak
signal strength can occur in a fringe area of the
cellular system. Buildings, tunnels, and bad
weather can block or interfere with reception.
Digital Indicator (2)
The digital indicator displays if you are receiving a
digital signal.
In Use Indicator (3)
The In Use (IU) Indicator appears when a call is in
progress.
In-Building Indicator (4)
The In-Building Indicator lights when the phone
accesses an In-Building Cellular System or other
non-public system.
No Service Indicator (5)
If you travel beyond the range of a cellular system,
the No Service Indicator appears to let you know
that calls cannot be placed or received from your
location.
