PROBLEM:
The treadmill circuit breaker trips during a workout.
SOLUTION:
Verify the following:
• Make sure the treadmill is plugged into a dedicated 20-amp circuit.
• Verify that you do not have the machine on an extension cord or surge protector.
• Confirm that the machine is not plugged into a GFCI-equipped outlet or on a circuit that has a GFCI-equipped outlet on it.
PROBLEM:
The running belt does not stay centered during a workout.
SOLUTION:
Verify the following:
• Make sure the treadmill is on a level surface.
• Verify that the belt is properly tightened and centered (Refer to the Adjustment section for detailed directions).
PROBLEM:
Operating speed appears inaccurate.
SOLUTION:
Auto-calibrate the treadmill:
• Power on the treadmill and have the safety key in position on the console. Press
and hold the elevation “+” and speed “-” buttons for approximately 5 seconds
to enter the Engineering Mode. The console will beep and “ENG0” appears in
the display.
• Press the Speed “+” or “-” button until “ENG2” appears in the display.
• Press, “ENTER” to select. Press, “START” to begin. The treadmill running
belt will begin to move automatically and the auto-calibration sequence will
properly set and store the speed values.
• Upon successful calibration, the treadmill will beep several times. The console
will automatically exit Engineering Mode and return to the start-up screen.
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.
If the above troubleshooting section does not remedy the problem, discontinue use and turn the power off.
PLEASE CALL CUSTOMER TECH SUPPORT AT THE NUMBER ON THE BACK PANEL.
The following information may be asked of you when you call. Please have these items readily available:
• Model Name
• Serial Number
• Date of Purchase (receipt or credit card statement)
In order for Customer Tech Support to service your treadmill they may need to ask detailed questions about the symptoms that are occurring.
Some troubleshooting questions that may be asked are:
• How long has this problem been occurring?
• Does this problem occur with every use? With every user?
• If you are hearing a noise, does it come from the front or the back? What kind of noise is it (thumping, grinding, squeaking, chirping
etc.)?
• Has the machine been lubricated and maintained per the maintenance schedule?
Answering these and other questions will give the technicians the ability to send proper replacement parts and the service necessary to get
you and your Horizon Fitness treadmill running again!
WARNING
DO NOT
stand on running belt while
calibrating – stand on the guide
rails. Treadmill will fluctuate between
low and high speeds for several
minutes until calibration is complete.
