KNOW YOUR UNIT

AEROBIC STEP FUNCTION

6

Helpful for building your health, the unit can measure the

number of aerobic steps that can be considered an effective
exercise to improve cardiovascular fitness.

The number of “aerobic steps” indicates the number of steps

that can be considered as effective aerobic exercise.

The unit displays the total number of steps in a day, which
satisfies the following two conditions:

1. Walk more that 60 steps per minute

2. Walk for more that 10 minutes continuously

The total duration you walked as the number of

aerobic steps is also displayed in minutes.

Example: If you walk for 20 minutes at the speed of 120 steps
per minute, the number of aerobic steps is 2400.

NOTE: Taking a rest for less than 1 minute during

continuous walking for more than 10 minutes
is considered as continuous walking.

7

Calorie/Amount of Burned Fat

The amount of fat burned is displayed in grams

simultaneously with the amount of calories consumed.
This information can be used for diet planning.

The calorie/amount of fat burned display indicates the

estimated calories consumed by walking calculated from the
weight, stride distance, number of steps, and walking speed.

The actual calories/amount of fat burned varies with age and
gender. To improve the accuracy of the calculation, multiply
the displayed calorie/amount of fat burned by the coefficient
in the table shown below.

Example of correction:

For a woman in her
50's with the calorie
display of 300, the
consumed calorie is
calculated as follows.

300 x 0.95 = 285 kcal

Correction coefficient

Man Woman

20's 1.10 1.07
30's 1.05 1.01
40's 1.02 0.97
50's 1.01 0.95
60's 1.00 0.95
70's 0.98 0.96
80's 0.95 0.95

STRIDE LENGTH MEASUREMENT

Measure your stride length before beginning to

set the pedometer.

1. How to measure your stride length

Walk 10 steps with your normal stride as illustrated below.

2. Measure the distance from START to END in inches.

3. Calculate your stride length by dividing the total
distance by 10.

4. Convert your stride length to feet and inches. You will set
the stride length using feet and inches.

Example:

Total Distance from START to END = 320'' (inches)

320” ÷ 10 = 32'' (inches)
32” = 2' 8'' (2 feet 8 inches)

Conversion Chart

12'' inches = 1' foot

24'' inches = 2' feet
36'' inches = 3' feet
48'' inches = 4' feet
