is displayed.
• The battery is low. Replace with a newbattery (CR2032). (See page 18)
Nothing is displayed at all.
• Nothing is displayed when the pedometeris in power-saving mode. Press the [SET]button or any other button.
• Check that a battery is inserted and that it
is correctly oriented. (See page 18)• The battery may be exhausted. Replacewith a new battery. (See page 18)• If you are using the pedometer for the ﬁrst
time, press and hold the [SET] button (forat least three seconds). (See page 6)• Press the reset button on the back of thepedometer. (See page 19)
The reading seems inaccurate.
• Check whether you are using the pedometer correctly. (See page 10)
Steps are not counted when I shake thepedometer.
• To prevent measuring errors, ‘walking’ isjudged to be performed after at least six
seconds of walking and the relevant number of steps up to that point are added
on. Shaking the pedometer once or twice
doesn’t have an impact on the number ofsteps counted.

20

No steps have been counted.
• If the initialization screen is ﬂashing, yoursteps will not be counted. (See page 6)
I don’t want the memory data to be erased
when I change the battery.
• The memory data, weight, stride lengthand target settings are not erased when
you change the battery. (At most, thedata for the most recent one-hour period
will be erased.) So you can avoid any
interruption in the data by changing thebattery in the morning before you start
walking.
How do I erase the memory data?
• Follow the reset procedure. (See page 17)
The buttons don’t respond.
• Press the reset button on the back of thepedometer. (See page 19)

What is an amount of exercise?
Amount of exercise (Ex) refers to theunit indicating the amount of physicalactivity. To prevent lifestyle diseases, you
are recommended to actively engage ina minimum of 23 Ex physical activities(exercise and daily activities) a week. It
is also recommended that you check withthe guideline by the health authority in yourarea.

Amount of exercise (Ex) = Intensity ofphysical activities (METs) x Time (hr).
Intensity of physical activities (METs)
multiplied by duration (hr) of physical activity
makes an amount of exercise (Ex).

METs = Metabolic Equivalents, the unitof intensity of physical activities
The unit for expressing the “intensity ofphysical activities” by the multiplicationequivalent to the counterpart during rest.
Normal walking is equivalent to 3 METs.
This product indicates the amount of
exercise (Ex) by the number of steps.
Reference)
Normal walking (3 METs) x 1 hour = 3 Ex
Fast walking (4 METs) x 1 hour = 4 Ex
