“CONSOLE INSTRUCTIONS –CONSOLE FUNCTION”
LEVEL: For this TFT console, the LEVEL HAS TWO MEANINGS, SINCERELY PLEASE TAKE
A LOOK BELOW,
For Manual, Constant Power Program, Level means “resistance/tension level”; Display
range: 1 ~ 20 resistance levels.
For FITNESS, RANDOM, ROLLING, FAT BURN, ASCENT, IRON MAN, MOUNTAIN,
WEIGHT LOSS, INTERVAL, VALLEY, Level means “Workout Difficulty Level”; Display
range: 1 ~ 20 workout difficulty levels. For example, The level of 20’s Watt range would be
heavier than the level of 8’s Watt range. The lower level of workout difficulty you select, the
workout difficulty Watt range would decrease, making more easier for user to exercise.
SPEED:
Display range: 0.0~99.9 km/h.
TIME:
Count Up: If a target time is not selected, TIME will count up from 0:00 to maximum 99:59
minutes.
Count Down: If a target time is set, (5:00 TO 99:00; 1 MINUTE INCREMENTS), the console
will count down from that selected target time to 0:00.
DISTANCE:
Display range: 0.0~99.9 km/h.
RPM:
Display range: 0~255.
CALORIES:
Display range: 0~9999.
METS:
Definition: MET or metabolic equivalent is a term commonly used to measure or express an
average person’s metabolic rate, is the amount of oxygen used by an average seated person. One
MET is the amount of energy or oxygen used to sit quietly for a minute.
1 MET= 3.5ml/kg/min (the body consumes 3.5 milliliters of oxygen a minute for each kilogram of
body weight), is the energy (oxygen) used by the body at rest, while sitting quietly or reading a
book, for example.
The harder your body works during the activity, the more oxygen is consumed and the higher the
MET level. If you are exercising at a level of 7 METS, this means that you are working about 7
times as hard as you would be at rest. You are consuming about 7 times the amount of oxygen as
you would at rest as well.
Activity that burns 3 to 6 METs is considered moderate-intensity physical activity.
Activity that burns > 6 METs is considered vigorous-intensity physical activity.

Resistance does not change even
though the quantity of RPMs
(Rotate Per Minute) increases or
decreases under the Level
Control Mode during workout.
No matter how fast you pedal, the
resistance is fixed.
The resistance depends on the value of RPM (Rotate Per Minute.)
“RPMRESISTANCE; RPMRESISTANCE ”
In order to remain at a consistent effort level (watts) (once you set up the
desired Watt value), the computer will start monitoring the user’s pedaling
speed/RPM.

Resistance will decrease (becomes lighter.)
On the contrary, the Resistance increases (becomes heavier resistance) when
