BASIC TROUBLESHOOTING
PROBLEM: At higher incline levels, a message reading
"Speed Range Error – Ending Workout" appears.
SOLUTION:
• This is a safety feature that automatically cuts power to
the drive motor when the speed is out of range due to the
combination of the load on the belt and high degree of incline
• To prevent an automatic end to your workout,
reduce the incline level percentage.
TROUBLESHOOTING HEART RATE
Check your exercise environment for sources of interference
such as fluorescent lights, computers, underground fencing,
home security systems or appliances containing large motors.
These items may cause erratic heart rate readouts.
You may experience an erratic readout under the following conditions:
• Gripping the heart rate handlebars too tight. Try to maintain
moderate pressure while holding onto the heart rate handlebars.
• Constant movement and vibration due to constantly
holding the heart rate handlebars while exercising. If you
are receiving erratic heart rate readouts, try to only hold
the grips long enough to monitor your heart rate.
• When you are breathing heavily during a workout.
• When your hands are constricted by wearing a ring.
• When your hands are dry or cold. Try to moisten your
palms by rubbing them together to warm.
• Anyone with heavy arrhythmia.
• Anyone with arteriosclerosis or peripheral circulation disorder.
• Anyone whose skin on the measuring palm is especially thick.
