■ 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.
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.

Adjusting Hand Positions
The watch hands can go out of alignment with the time on the digital display if it
is exposed to strong magnetism or impact. If this happens, you should adjust the
hand positions.
Note
You do not need to perform the operation below as long as the analog hands
indicate the same time as the digital display.

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).
Battery
■ "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.
