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 (sleep mode)
After 5 minutes with no button being pressed, the
message “sleep” appears, then 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.
