most issues. If none of these troubleshooting steps solves your issue or if your issue is not listed you may
contact our Tech Support using the resources listed at the bottom of this page.
Symptom: The motors do not move at all, but the program downloads successfully.
Check: The power switch may be in the POWER ON/MOTORS OFF position instead of POWER ON/MOTORS
ON.

two seconds.
