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.
2. Measure the distance from START to END in inches.
3. Calculate your stride length by dividing the total distance by 10.
Example:
Total distance = 320’’

Conversion Chart
12 inches = 1 foot
24 inches = 2 feet
36 inches = 3 feet
48 inches = 4 feet

READING THE CURRENT DISPLAY
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.

MEMORY FUNCTION
The unit stores 7 days of measurements for steps, distance, calories, aerobic steps
and pitch.
The current day’s data is automatically stored in memory when the time reaches
12:00AM (0:00). The display will return to 0.
NOTE: • Thetimemustbecorrectlysetintheunit.
