AUTO MOVEMENT SENSOR
1. To filter out random movements, the unit remains in 
standby mode until 5 continuous steps are registered.
Only then are the 5 steps calculated in, and an Active
 indicator “▲” appears on the upper left of display.
2. When regular walk/run movement stops, after 2 seconds 
the timer pauses and the unit switches to standby status
(Active indicator “▲” disappears).
RESETTING YOUR PEDOMETER 
Most people prefer to reset step counts daily. To reset: While 
displaying Day’s STEPs, DISTANCE, or ACTIVITY TIME, press
and hold yellow RESET button for at least two seconds to
reset all of these to zero. When displaying Total STEPs, press
yellow RESET button for two seconds to reset all counts,
including Total STEPS, to zero.

REPLACING THE BATTERY
When the display starts to dim or goes blank, it is time to replace 
the battery. Your pedometer uses one Type LR43 (L1142) 1.5 volt
alkaline battery. To replace:
1. Insert a coin into the slot on the bottom of the case, and twist
 counterclockwise to loosen the case front. Lift case front away.
2. Using a pen or other thin object, push battery sideways out 
of its holder. Replace it with a new battery. The battery’s
positive (+) terminal should be FACE UP while you put it into
 the pedometer.
3. Align case front over the pedometer and press gently to snap 
cover back into place, starting with top.
