Altitude Measurement

Q1Readings produce different results at the same location.
Watch readings are different from altitude information available from other sources.
Correct altitude readings are not possible.

Relative altitude is calculated based on changes in barometric pressure measured by the watch’s pressure sensor. This means that barometric pressure changes can cause readings taken at the same location to be different. Also note that the value displayed by the watch may be different from the actual elevation and/or sea level elevation indicated for the area where you are located. When using the watch’s altimeter while mountain climbing, it is recommended that you regularly calibrate its readings in accordance with local altitude (elevation) indications.

Q2Following a relative altitude reading, the watch’s second hand points to 9 o’clock.

The second hand will move to 9 o’clock if a reading is outside the allowable altitude measurement range (-700 m to 10,000 m (-2,300 to 32,800 feet)). If [ERR] is displayed, there may be a problem with the sensor.

Q3[ERR] appears during measurement.

There may be a problem with the sensor. Try taking another measurement.

If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.

Digital Compass

Q1The entire display is flashing.

Abnormal magnetism has been detected. Move away from any potential source of strong magnetism and try taking a reading again.

  • If the display flashes again, it could mean that the watch itself has become magnetized. Move away from any potential source of strong magnetism, perform figure 8 calibration or 2-point calibration, and then try taking a reading again.

Q2[ERR] appears during measurement.

There is a problem with the sensor or there may be a source strong magnetic force nearby. Move away from any potential source of strong magnetism and try taking a reading again. If [ERR] keeps appearing after multiple measurement attempts, contact a CASIO service center or your original retailer.

Q3[ERR] displayed following figure 8 or 2-point calibration.

[ERR] on the display could indicate a sensor problem.

  • If [ERR] disappears after about one second, try performing 2-point calibration again.
  • If [ERR] keeps appearing after multiple attempts, contact a CASIO service center or your original retailer.

Q4Direction information indicated by the watch is different from that indicated by a backup compass.

Move away from any potential source of strong magnetism, perform 2-point calibration, and then try taking a reading again.

Q5Readings at the same location produce different results.
Cannot take readings indoors.

Move away from any potential source of strong magnetism and try taking a reading again.
