be reduced.
If you are experiencing problems getting relatively accurate step counts
Any of the conditions below may make proper measurement impossible.
x Wearing slippers, sandals, or other footwear that encourages a shuffling gait x Walking on tile, carpeting, snow, or other surface that causes a shuffling gait x Irregular walking (in a crowded location, in a line where walking stops and starts at
short intervals, etc.)
x Extremely slow walking or extremely fast running x Pushing a shopping cart or baby stroller x In a location where there is a lot of vibration, or riding in a car or other vehicle x Frequent movement of the hand or arm (clapping, fanning movement, etc.) x Walking while holding hands, walking with a cane or stick, or engaging in any other
movement in which your hand and leg movements are not coordinated with each
other.

Note
x Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1.
x The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change it except after you have the watch’s battery replaced.
x The day of the week changes automatically when the date changes. x While the 12-hour format is selected for timekeeping, a P (PM) indicator will appear
for times from noon to 11:59 p.m. No indicator appears for times from midnight to 11:59 a.m. With 24-hour format, time is displayed from 0:00 to 23:59, without any P (PM) indicator.
E-21
Pedometer
The watch has a built-in 3-axis accelerometer that counts the steps you take. You can specify a daily step goal and keep track of your step goal progress. A Step Reminder function helps to keep you from sitting too much.
Pedometer Precautions
While the watch is on your wrist, the pedometer may detect non-step movements and count them as steps. Also, abnormal arm movements while walking may cause a miss count of steps.
Wearing the Watch
OK NG
x Normal daily non-walking activities (cleaning, etc.) x Wearing the watch on your dominant hand x Walking for less than 10 seconds x Watch hand movement (by the hand shift function, etc.)
Power Saving
To save power, sensor operation stops automatically if there is no movement detected by the watch and you do not perform any operation for two to three minutes.
To ensure proper step count measurement, wear the watch as shown in the illustration nearby. Wear the watch on your wrist, with the band tightened securely.
E-23
E-25
Pedometer Details
Step Count
x The step counter can count from 0 to 999,999 steps. If the step count exceeds
999,999, the maximum value (999,999) remains on the display.
x The step count is not displayed at the beginning of a walk in order to avoid
miscounting of non-walking movements. It appears only after you have continued
walking for about 10 seconds, with the number of steps you took during that time
added to the total.
x The step count is automatically reset to zero at midnight each day. x You can also manually reset the daily step count that is displayed in the
Timekeeping Mode. Note that doing so does not reset the daily step count on the
history screen. This makes the displayed step count zero and counts steps from
there. This comes in handy when you want to count the number of steps between
twopoints. See “To reset today’s step count” (page E-31).
E-26
Checking Step Count
To check step count
1. In the Timekeeping Mode, use A to cycle through step count information as
shown below.

2. Hold down D for about two seconds until zero starts flashing and then remains
displayed without flashing.
x This operation resets the displayed step count value only, and does not affect
the current day’s total step count maintained in memory. You can view the current day’s step count total using step count history.

Important!
x Battery replacement will cause step count history data to be deleted.
The GOAL indicator will flash on the display to let you know you attained your daily step goal.
x The GOAL indicator will be cleared from the display at
midnight of the current day. The GOAL indicator will also be cleared from the display if you change your daily step goal to a value that is greater than the current day's step count.

Count of the Days You Attained Your Daily Step Count Goal (GOAL)
x The day count value is incremented each time you attain your daily step count goal
(GOAL).
x If you change your daily step goal to a greater value after you attain a previous daily
step goal, the watch will still count the current day as successfully attaining your daily step goal (based on the previous value).
x If, before you reach your daily step goal, you change it to a value that is less than
the current goal value, the day will remain counted as successful attainment of your step goal.
x To return to the Timekeeping Mode, press C.
Step Reminder
Step indicators
Studies indicate that sitting too much has an adverse effect on human health. A Step Reminder feature displays an indicator and sounds an alert whenever the watch determines that you have not walked for a specific amount of time. This helps to ensure that you are getting enough exercise on a regular basis. Make sure that you keep walking for at least five minutes after activating Step Reminder.
x The initial default Step Reminder setting is OFF.

Troubleshooting
Time Setting
■ The current time setting is off by one hour.
You may need to change standard time/daylight saving time (DST) setting. Use the procedure under “Adjusting the Digital Time and Date Settings” (page E-18) to change the standard time/daylight saving time (DST) setting.
Pedometer
■ Step count is not correct.
If the band is loose, the pedometer will count steps but step count accuracy may be reduced. For details, see “Pedometer Precautions” (page E-23).
E-75
■ The step count does not increase.
The step count is not displayed at the beginning of a walk in order to avoid miscounting of non-walking movements. It appears only after you have continued walking for about 10 seconds, with the number of steps you took during that time added to the total.
■ “ERR” appears on the display while I use the watch.
Subjecting the watch to strong impact can cause sensor malfunction or improper contact of internal circuitry. When this happens, ERR (error) will appear on the display and sensor operations will be disabled.
x If the message does not disappear after about three minutes or if it keeps
appearing, it may indicate sensor malfunction. Contact your original retailer or CASIO service center.
■ History data was deleted.
Battery replacement will cause step count history data to be deleted.

■ “R” is flashing on the digital display.
This happens when battery power is low or after the light or some other function is turned on repeatedly over a short amount of time, which temporarily runs down the battery. All functions other than timekeeping are disabled while R is flashing on the display. If R remains on the display or if it keeps appearing, it may indicate that the battery needs to be replaced. Request battery replacement by your original retailer or authorized CASIO service center.
