Nautilus® Sport Series Treadmill Owner’s Manual
TREADMILL DISPLAY DEFINITIONS
The following describes the display functions and specifi cations on the Sport Series treadmills.
Incline — The treadmill incline is displayed as a percentage of elevation. The Sport Series treadmills have an incline
range of 0 to 15%.
Time — The selected workout time is displayed in the center of the lower display window on the LE-X and LC displays.
In the Time Based workouts, the timer will count down to 0:00 from the preset time you have selected. In Distance
Based programs, HRC Weight Loss and HRC Cardio, the timer will count up. The timer will also count up if START is
pressed without selecting a workout program (this is a QUICK START).
Speed — The treadmill speed is displayed in miles per hour (or kilometers per hour). The Sport Series treadmills have a
speed operation range of 0.5 mph to 12 mph (0.8 kph to 19.2 kph). For safety reasons you may also limit the maximum
speed in the Management Menu.
Heart Rate — Current heart rate is displayed in beats per minute.
Percentage of Maximum Heart Rate
— An approximation of maximal heart rate is calculated by subtracting the user’s
age from 220. Percentage of maximum heart rate will only be shown in HRC programs or when a user selects their name
in the My Nautilus™ menu since these are the only times the user’s age is known. My Nautilus™ software is a fi tness
cartridge feature that is sold separately (see Fitness Cartridge section in the owner’s manual).
Example:
User is 40 years of age:
220 – 40 (age) = 180 — 180 Beats per minute would be the approximate maximum heart rate for a 40-year-old
user.
180 x 75%= 135 — 135 Beats per minute would be the heart rate of a 40 year old user exercising at 75% of their
maximum heart rate.
(See the Heart Training programs for more information.)
Distance — Provides a cumulative total of the equivalent distance, in miles (or kilometers if your display is set to metric
units), you have traveled.
Calories — Provides a current total of the number of calories burned during a workout. Note: This number is only
an approximation as a user’s caloric expenditure will vary signifi cantly based on a person’s age, gender, weight and
metabolism.
