Calories

By measuring the intensity of your activity, the unit can 
calculate the amount of calories burned.

Aerobic steps

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 walk of more than 10 minutes, 
this will be regarded as part of “a continuous walk”.

Pitch

The average number of Aerobic steps per minute is 
displayed. The faster you walk, the more calories you 
will burn.

The battery saving mode

After 5 minutes with no button being pressed, the display 
will automatically turn off. However, the unit continues 
counting steps. This mode extends the battery life.
Press 

 or 

 to activate the display again.

STRIDE LENGTH MEASUREMENT

Measure your stride length before setting the pedometer.

How to measure your stride length

1.   Walk 10 steps with your normal 

stride as illustrated below.

inches.

3.  Calculate your stride length by dividing the total 

distance by 10.

Total distance = 320''

320 ÷ 10 = 32 inches (2 feet 8 inches)

 Conversion 

Chart

12 inches = 1 foot
