Module No. 3554

Barometric Pressure Change Indications

Whenever the watch detects a significant change in air pressure readings (due to sudden altitude change, or to the passage of a low pressure or high pressure area), it will perform a sound and/or vibration operation and display a flashing arrow to let you know. The arrow that appears shows the direction of the pressure change. These alerts are called “Barometric Pressure Change Indications”.

The watch will notify you by a 10-second sound/vibration operation when there is a sudden drop in atmospheric pressure.

A four-second sound/vibration operation will notify you when there is a sudden rise in atmospheric pressure, or the passage of high or low pressure.

This indication:

Means this:

3452_baro_normal_dot-info01_fall

Sudden drop in pressure

3452_baro_normal_dot-info02_rise

Sudden rise in pressure

3452_baro_normal_dot-info03_rise_fall

Sustained rise in pressure, shifting to a fall

3452_baro_normal_dot-info04_fall_rise

Sustained fall in pressure, shifting to a rise

Important!

To ensure correct barometric pressure change indication operation, enable it in a location where the altitude is constant (such as a lodge, camp area, or on the ocean).

A change in altitude causes a change in air pressure. Because of this, correct readings are impossible. Do not take readings while ascending or descending a mountain, etc.

  1. Display the current time screen.

  2. Use (A) and (D) to select [BAROMETER].

  3. 3554_BARO
  4. Press (C).

  5. This displays the current barometric pressure and temperature.

  6. Hold down (A) for at least two seconds.

  7. This displays the barometer/temperature measurement setting screen.

    3554_BAR_TEM_set_caps
  8. Use (A) and (D) to move the pointer to [BAROMETER INFORMATION].

  9. Press (C).

  10. Use (A) and (D) to select a barometric pressure change indication setting.

  11. [ON]

    Enables the barometric pressure change indication.

    [OFF]

    Disables the barometric pressure change indication.

  12. Press (C) to complete the setting operation.

  13. After the setting operation is complete, a check mark appears for a few seconds, and then the barometric pressure/temperature setting screen re-appears.

  14. Press (E) to exit the setting screen.

Note

If the barometric pressure change indication is enabled, readings are taken every two minutes even while the watch is performing an operation other than barometric pressure and temperature measurement.

The barometric pressure change indication becomes disabled automatically 24 hours after it is enabled.

Power Saving is disabled while barometric pressure change indication is enabled.

The barometric pressure change indication will become disabled automatically when the battery becomes [CHG] or lower.
