When placed horizontally to the ground 

 
If the main body is vertical, the counting function is available even if the product tilts from side to 
side or is turned upside down.

 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).
