Troubleshooting Glossary

1. Turn the ShockClocks on and begin recording using the Remote Record Switch.  Lift up on the rear axle to move the swingarm through its full range of travel (all the way up), and then let it back down.  

 

Note: Use the Remote Record Switch so both ShockClocks begin recording at the same time – this is critical!

 

2. Stop recording and download both ShockClocks.  When naming the files include the abbreviation “WH” in the wheel file and “SK” in the shock file.
