of the station initiating the call and one indicating that a request for a change of
working channels is being made. The channel does not change until you accept.
The 2 alternating pages of data are recorded in the Call Log. The envelope icon

blinks until you accept the call, reject the call, or open the resulting unread
message stored in the Log. See page “Received Calls (Logs)“ on page 94.
