Exiting Data Calls
Under normal conditions, the radio enters the scan lockout mode and returns

during a data call, one of the following conditions occurs, the data call is
immediately terminated and the radio performs the desired function:
• The PTT is activated
• The PTT is in Public Address mode.
• An emergency is declared by pressing the pre-programmed emergency
button.
• A group or system change is made.
Scan Lockout Mode
Following the transmission or reception of a data call, if scan is enabled,
scanning will stop temporarily (duration pre-programmed). During this time
the scan LED will flash to indicate that scan is enabled but temporarily
suspended. This mode is normally exited when the pre-programmed time
expires; however, the following actions will terminate the scan lockout mode
before the timeout is completed.
• The c (System Model) or C (Scan Model) button is pressed.
• The PTT is pressed.
• A group or system change is made.
