FCC Warning - Possible Radio / Television Interference
EN ISO 20975 Class SA (Bikes and Arc Trainer only): Professional and / or commercial use.
EN ISO 20975 Class SB (Treadmill only): Professional and / or commercial use.
EN ISO 20957 Class S: Professional and / or commercial use.
NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio
frequency energy, and if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
EN ISO 20957 Class H: Home use.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio frequency energy, and if not installed
and used in accordance with the user manual, may cause harmful interference to radio communications. However,
there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Cross-Trainers only:
Cross-Trainers:
For EN ISO 20957-9: 2016 Class SA accuracy testing, power at the crankshaft was measured by connecting the training
equipment to a dynamometer. The crank was rotated and torque measured per EN ISO 20957-9: 2016 Class SA
operating test conditions. Accuracy of the resulting watts displayed on the console and actual watts measured by
dynamometer were found to be within the tolerance of EN ISO 20957-9: 2016 Class SA (+/- 5 Watts up to 50 Watts
and +/- 10% over 50 Watts.
FlexStrider Variable Stride Trainer only:
For EN ISO 20957-9 Class A accuracy testing, input mechanical power was measured by connecting the resistance
device (generator) with the console to a dynamometer. Torque test data was recorded across the available speed and
resistance level settings. The mechanical resistance was then determined by a deceleration test without a user riding it,
measuring precisely both motions exhibited by the product: 1) The rotational deceleration measured from the starting
speed and time, at minimum stride, until the rotating mechanism comes to a stop, and 2) The angular deceleration
measured from a starting angle and time until the pedal leg lever assembly comes to a stop. The torque required to
stop the unit was then calculated from the system inertia, input speed, angle, and time to stop, and then added to the
dynamometer data to obtain the total system torque. From measured torque and speed, the input mechanical power
and variance from displayed power were calculated. At level 10 and a constant 40 RPM, displayed wattage was 128
watts, with a 2.1% variance from input power on the test equipment. At level 15 and a constant 60 RPM, displayed
wattage was 167 watts, with a 4.6% variance from input power on the test equipment.
Arc Trainer only:
Arc Trainers:
For EN ISO 20957-9: 2016 Class SA accuracy testing, power at the crankshaft was measured by connecting the training
equipment to a dynamometer. The crank was rotated and torque measured per EN ISO 20957-9: 2016 Class SA
