p.15 •It takes approximately 6 seconds for this product to recognize your movement as walking. After
you walk for a while, the pedometer displays the total number of steps taken up to that point, and
subsequently starts to display the number of steps by adding one step at time in accordance with
each step taken.
•In the following cases, the pedometer may not be able to measure the walking correctly:
Jogging or walking at an extremely slow pace
This product is specifically designed for walking. It may not correctly count steps if you are running
or walking at an extremely slow pace.
When this product moves irregularly
- Where you hang the pedometer around your bag or neck and it bounces off your body etc.
- Where the pedometer moves irregularly in your bag or pocket
Irregular walking
- Walking like shuffling
- Walking in sandals, Japanese sandals or any other similar footwear
Use in up-and-down movement or at places often exposed to vibrations
- Ascending/descending the stairs or a steep slope
- Movement of standing up and sitting down
- Sports other than walking
- Vibrations while riding a vehicle (e.g., car, train, bus)
Jogging or walking while mountain climbing
p.16 EXERCISE (Ex)
Exercise and Physical Activity Reference for Health Promotion <Exercise Guide 2006> prepared by
the Ministry of Health, Labour and Welfare
For health promotion and to prevent lifestyle-related diseases, the goal is set at 23 exercises (Ex)
per week by active physical activity, of which 4 exercises (Ex) by active exercise.
What is exercise (Ex)?
Exercise (Ex) is a unit to express “the quantity” of physical activity, calculated by multiplying the
intensity of physical activity (METs) by the duration of the activity (hour).
What is MET?
MET (metabolic equivalent) is an index for intensity of physical activity, calculated as energy
expenditure during a specific physical activity divided by sitting/resting energy expenditure. By
defining MET of setting/resting as 1, for example, that of normal walking (flats 67m/min) is 3METs.
Reading the exercise (Ex) value
This product converts the measured walking data into the “exercise (Ex) value” and displays it.
Examples of exercise (Ex) value calculation
If walking is taken as physical activity, walking at normal speed and walking in your daily life will
be “normal walking” (= physical activity) while walking with the stride length consciously increased
and fast walking will be “brisk walking” (= active exercise).

Since this product is a pedometer of the biaxial sensor type, do not tilt it 30°or more or turn over in
your pocket or bag.

Normal walking (intensity: 3METs)
(Example) When physical activity with 3METs (normal walking) is performed for 7 hours in total
for a week:
3METs ×7 hours = 21 exercises (Ex)
Brisk walking (intensity: 4METs)
(Example) When active exercise with 4METs is performed for one hour in total for a week:
4METs ×1 hour = 4 exercises (Ex)
Total for a week: (Example) 21+4=25 exercises (Ex)
