GENERAL TROUBLESHOOTING TOC
•UPDATE TO THE LATEST SOFTWARE VERSION, if possible.
oReference the Software Update topic if anything unexpected happens.
•Cycling power is recommended as the first attempt to fix most failures, and after major repairs are
implemented.
•To access Service Modes:
oFrom idle: Press & hold “MATRIX” logo for ~5 seconds, then type 3001 enter.
oFrom workout: Press the “Hamburger” button in upper right. Press & hold on “Options” in
upper left until keypad appears, then type 3001 enter.
•If multiple, identical machines are available, swap suspected failed parts (console, LCB, cables,
etc.) and observe if the failure follows.
USING THIS GUIDE
Read & understand the General Troubleshooting section above.
Given a problem description, link to the topic that appears most fitting from the ToC on the first page or
Find (ctrl-f) by keyword. Find the Green flowchart bubble that best describes the specific issue, and follow
the flow through asking questions, taking measurements, and suggesting corrective action. The
“Additional Information” section within each topic contains notes and details pertaining to that topic.
After each corrective action is taken, re-evaluate if the failure has been resolved. Some indications have a
straightforward order of attempts, and not all steps are always necessary if a lower-level fix resolves the
issue.

Touchscreen failures may be reported as freezing.

Additional Information
•All workouts are maintained by software. If software updates don’t resolve issues, hardware
failure is indicated.
•Also consider if LCB is working properly if workouts pausing or stopping. LCBs can be swapped
between similar frames to troubleshoot. If you swap LCBs or Consoles between bikes to
troubleshoot, be sure to return them to their original frames, as they contain critical calibration
data.

can provide the password, if appropriate. Facilities may have their own networks installed.
