Pedometer

You can use the pedometer to keep track of your step count while walking, engaging in your normal daily activities, etc.
Counting Steps
If you are wearing the watch correctly, the pedometer will count your steps as you walk or engage in your normal daily activities.
Important!
• Since this watch’s pedometer is a wrist-worn device, it may detect non-step movements and count them as steps. Also, abnormal arm movements while walking may cause a miss count of steps.

● Getting Ready
To enable the most accurate step count, wear the watch with the face on the outside of your wrist and tighten the band securely. A loose band may make it impossible to obtain a correct step count.

● Counting Steps

The pedometer will start counting your steps when you start walking. The step indicators show whether or not the step count is being incremented.
Alternating at one-second intervals: Walking (step count being incremented) Both displayed: Not walking (step count not being incremented)
● To check the step count
Displaying the Step Count…EN-24

Displaying the Step Count

1. Enter the Timekeeping Mode.
   Selecting a Mode…EN-17

2. Use E to display the step count.

• Interpreting the Step Count Graph

The Step Count Graph shows the number of steps (up to 1,000) you have taken each hour. This lets you easily check your walking pace over the past 7 or 8 hours.

• The Step Count Graph is not displayed while the step count is zero.

• Graph contents are normally updated at the top of each hour.

• Checking Your Progress to Your Daily Step Target
  The graphic display area shows your current progress toward achieving a daily step target specified by you.
  Example: Daily target of 10,000 steps

Note

• The step count can show a value up to 999,999 steps. If the step count exceeds
  999,999, the maximum value (999,999) remains on the display.

• The step count is not displayed during the first 10 seconds of a walk in order to avoid miscounting of non-walking movements. After you have been walking for about 10 seconds, the count appears, including the steps you took during the previous 10 seconds.

• The step count is reset to zero at midnight each day.

• To save power, step counting stops automatically if you take off the watch (no detectable watch movement) and you do not perform any operation for two or three minutes.

• Graph contents are normally updated at the top of each hour, and when any one of the events below occurs.
  − When accelerometer operation is stopped to save power
  − When counting is not possible due to accelerometer error or insufficient power

Resetting Today’s Step Count

   This causes the current daily step target to flash.

3. Use D and E to change the daily step target setting.

4. Press A to exit the setting screen.

Causes of Incorrect Step Count

Any of the conditions below may make proper counting impossible.

• Walking while wearing slippers, sandals, or other footwear that encourages a shuffling gait
• Walking on tile, carpeting, snow, or other surfaces that cause a shuffling gait
• Irregular walking (in a crowded location, in a line where walking stops and starts at short intervals, etc.)
• Extremely slow walking or extremely fast running
• Pushing a shopping cart or baby stroller
• In a location where there is a lot of vibration, or riding on a bicycle or in a vehicle
• Frequent movement of the hand or arm (clapping, fanning movement, etc.)
• 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
• Normal daily non-walking activities (cleaning, etc.)
• Wearing the watch on your dominant hand
• Walking for 10 seconds or less

Stopwatch

The stopwatch measures elapsed time in 1/100-second units for the first hour, and in 1-second units after that for up to 24 hours.
In addition to normal elapsed time measurements, the stopwatch also lets you take split time and lap time readings.
Note

• Up to 200 split time and lap time records can be stored in watch memory. Performing a lap or split time operation while there are already 200 records in memory will cause the oldest record to be deleted automatically to make room for the new one.
• You can use the Recall Mode to view the latest measurement data.
  Viewing Lap/Split Records…EN-43

● Getting Ready
Enter the Stopwatch Mode.
Selecting a Mode…EN-17

Split Times and Lap Times

Troubleshooting

Pedometer

• Displayed step count is not correct.
  While the watch is on your wrist, the pedometer may detect non-step movements and count them as steps.
  Pedometer…EN-21
  Also, step count problems can also be caused by how the watch is being worn and abnormal arm movement while walking.
  Counting Steps…EN-21

• 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 the first 10 seconds included in to the total.

• [ERR] appears when using the pedometer.
  [ERR] (error) appearing on the display indicates malfunction of the sensor or internal circuitry, making sensor readings impossible. If the message does not disappear after about three minutes or if it keeps appearing, it may indicate sensor malfunction.
  Alarm

• The alarm does not sound.
  Is the alarm setting turned on? If it isn’t, turn it on so it will sound.
  Enabling/Disabling an Alarm or the Hourly Time Signal…EN-57
  Indicators

• I don’t know what mode the watch is in.
  You can determine the current mode by checking the watch display. Use C to navigate between modes.
  Selecting a Mode…EN-17

Battery

• is flashing on the digital display.
  This indicates that battery power is getting low.
  Battery Replacement…EN-63

• 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.
