About the Pedometer
Walking for good health
Aerobic activities strengthen the heart and lungs, making
them more efficient, and also allows your body to use fats
and sugars more efficiently, thus burning more calories.
Walking is one of the most suitable form of aerobic
exercises for people of all ages.
It is recommended that all people should increase their
regular physical activity to a level suitable to their capaci-
ties, needs, and interest. One should set a long-term goal
to incorporate at least 30 minutes of moderate-intensity
physical activity on all, if not, most days of the week. The
“number of aerobic steps” of the pedometer aims to help
you achieve this.
Number of aerobic steps displayed
“Number of aerobic steps” indicates the number of steps
that can be considered as effective aerobic exercise.
The pedometer displays the total number and duration of
aerobic steps you take in a day based on the following
two criteria:
1. Walking more than 60 steps per minute.
2. Walking for more than 10 minutes continuously
(with less than 1 minute of rest).
Example:
If you walk for 20 minutes at the speed
of 120 steps per minute, the number of
aerobic steps is 2400.

About the Pedometer
Calorie/amount of burnt fat displayed
The calorie/amount of burnt fat display indicates the
energy consumed by walking and is calculated from
the weight, stride distance, number of steps, and
walking speed.
For a more precise calorie/amount of burnt fat value,
multiply the calorie/amount of burnt fat value displayed
by the coefficient in the following table.
Example of correction:
For a woman in her 50's with calorie display of 300, the
actual consumed calorie is calculated as follows.
300 x 0.95 = 285 kcal
Correction coefficient for calorie display
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

Before Using The Unit 9
How to Set Time, Weight, and Stride Distance
1. Turn on the power by pulling out the insulation film.
You do not need to re-insert the film.
When the power is turned on, the
time setting screen will appear
and all the characters on the
display illuminate.
2. How to measure your stride distance.
Correct stride distance is measurement from the tip of
your toe to the other one. To measure the correct
average stride distance, divide the total distance of
ten steps you walked by the number of steps (10).
Example: When you walk 5.5 meters,
5.5 m (total distance) ÷10 (number of steps)
= 0.55 m (55 cm)
