Exiting Data Calls

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.
