+Sailfish devices have a built-in customer service diagnostic tool, abbreviated **CSD**. This test tool makes it possible for users to verify the key functions of their devices.
+
+
+
+# Opening the CSD
+
+Access the tool by tapping the item "Build" five times or more in "Settings > System > About product". The tool pops up in a few seconds showing the Disclaimer page first.

+  </span>
+</div>
+
+
+Please read the text carefully. Accept the disclaimers by tapping 'Accept' at the top right corner.
+
+NOTE:  _Interpreting the test results correctly may not be easy without suitable technical training.  Please seek help from the **[Sailfish Forum](https://forum.sailfishos.org/)** or from **[Jolla Customer Support](https://jolla.zendesk.com/hc/en-us/requests/new)**._

+
+# Main categories
+
+There are three main categories of tests (Pic 3):
+
+1.  Factory tests
+2.  Hardware tests
+3.  Device status
+
+We recommend using categories #2 and 3#. The only reason for using category #1 would be to run some long-lasting tests. Everything else and more are covered by category #2. The device status category provides data mainly on power consumption.

+  </span>
+</div>
+
+
+
+# All hardware tests
+
+Tap "All tests" to enter the category of Hardware tests.
+
+The tests are grouped by technology areas. The groups are shown at the right of the display (Pic 4). After executing a test, the verdict is shown with green or red colour in the list of tests (Pic 5).
+
+The test results can be cleared by pulling down "Clear test results" for the next round.

+
+## Test procedures
+
+Each test has a short written procedure. Please follow it precisely.
+
+Picture 6 below shows the test procedure of the loudspeaker test for example.

+  </span>
+</div>
+
+
+After executing a test, some of them give the verdict of "Pass" or "Fail" automatically (Pic 7 below) whereas in some other cases, you must decide on the verdict based on your interpretation of the test results (Pic 8). In such a test, tap the appropriate button (Pass or Fail).
