Samsung SCH-8500 - Manual (Page 26)

Note: The no service indicator will always appear
when you turn on your phone. As soon as service is
found, the indicator disappears.
Roaming: This icon indicates you are “roaming” off the
Sprint PCS Digital Network. If you are:
in your home service area, this indicator will not
display.
in a preferred analog or digital roaming area
(where Sprint PCS has a roaming agreement in
place), this indicator will be steady on, but not
flashing.
in an analog or digital coverage area that is not
covered by a Sprint PCS roaming agreement, this
indicator will flash once every second.
Message indicator: This icon indicates you have
message(s) waiting. The message(s) can be a voicemail
notification (VMN), page, text, or Sprint PCS Wireless
Web message(s). Press to see the Message menu, or
press and hold to be connected to Sprint PCS
Voicemail.
Analog mode: This icon indicates your phone is
operating in analog mode. Your phone will be able to
place and receive calls where Sprint PCS has roaming
agreements in place, but quality will be similar to calls on
other analog cellular networks. Also, some features of
your phone may not be available in Analog mode.
Vibrating Ringer: This icon indicates that an incoming
call will vibrate the phone rather than ring it. This feature
can be used for quiet situations where you don’t want
your ringer to disturb others or for loud situations where
the ringer cannot be heard.
Battery strength: This icon is always displayed when
your phone is on, and shows the level of your battery
charge. The more black bars you see, the greater the
charge. When the battery becomes very low, an empty
box appears and the phone flashes an alert; this
indicates your phone is about to turn itself off.
