Dear customer, 
Thank you for purchasing this OMRON Step Counter. The 
new Walking style IV will measure your physical activity 
accurately and helps you to assist your diet or motivates 
you to reach your daily walking target. 
This Step Counter can count the number of steps while in 
a bag or pocket as well as when being worn around the 
neck, giving you a choice of options on how to carry it. 
Use it every day for an easy way to monitor your health.
INTRODUCTION
 The OMRON Walking style IV features 
Aerobic steps (brisk walking)
Aerobic steps are the physical exercise that helps us 
stay healthy. Aerobic steps are counted separately 
when walking more than 60 steps per minute and more 
than 10 minutes successively. If a rest of less than 
1 minute is taken after a continuous brisk walk of more 
than 10 minutes, this will be regarded as part of 
“a continuous walk”.
Calories burned
The intensity of walking is measured and the amount of 
calories are calculated.
Action mode
This stores the measurement values* for a specified 
period or session. These measurement values are 
separate to the measurement values stored for each 
day.
* Steps counted/Distance/Calories burned/Aerobic steps
 symbol at 10,000 steps
The   symbol appears if you have done 10,000 steps 
within a day (will not appear on the Action mode display 
and Action mode memory display).

Notes:
• If no settings are made for more than 5 minutes, the
