+====== 7. Operation ======
+===== Operation through SSH =====
+connect via SSH - adjust the port number and possibly also the user ''scanner''
+<code>
+ssh -p 9001 scanner@hayguen.hopto.org
+</code>
+in case you are already connected to the host - as different user
+<code>
+sudo su -l scanner
+</code>
+start the scanner (as scan user)
+<code>
+startBgScanLoop.sh
+</code>
+stop the scanner (as scan user)
+<code>
+stopBgScanLoop.sh
+</code>
+check results while scanning - before having uploaded (as scan user)
+<code>
+scanEvalFMcmpPS.sh
+scanEvalFMcmpPI.sh
+scanEvalDABens.sh
+scanEvalDABensTii.sh
+scanEvalDABprogs.sh
+</code>
+upload all results (as scan user)
+<code>
+stopBgScanLoop.sh wait
+prepareScanResultsForUpload.sh all
+uploadScanResults.sh
+</code>
+probably, you want to edit the upload comment ''FMLIST_UP_COMMENT'' - before uploading (as scan user)
+<code>
+cd ~/.config/fmlist_scan
+nano fmscan.inc
+</code>
+and after the upload, you might want to restart the scanner (as scan user)
+<code>
+startBgScanLoop.sh
+</code>
+and probably also restart monitoring
+<code>
+monitorBgScanLoop.sh
+</code>
+===== Operation through Webserver =====
+all operations can be done through the webserver
+see [[fmlist_scanner:setup_scanner_software#setup_control_webserver|'Setup control webserver' in setup_scanner_software]]
+===== Buzzer status tones =====
+The scanner reports its status primarily via the piezo-buzzer. The detection of Broadcast-FM and DAB stations is reported with tone sequences on each scan. See configuration entry ''FMLIST_SCAN_PWM_FEEDBACK''
+^ Event                               ^ Tone sequence                ^
+| //Welcome// at startup              | short short short long short |
+| FM success (at least 1 transmitter) | short short, short           |
+| FM failure                          | short short, long            |
+| DAB success (at least 1 station)    | short long, short            |
+| DAB failure                         | short long, long             |
+| Write error for result              | 3 x (long long long)         |
+In addition to these operating results, there are other tone sequences to sign
+  * Start the scanner
+  * Error status, e.g. no RTL dongle found
+  * Scan results saved
+Test / listen with ''scanToneFeedback.sh'' or the webserver
+The individual LED colors have no dedicated meaning. They are switched over for each recognized station. There is no changeover if the next station is detected within/below one second - in order to limit the changes.
