Module No. 3553

Sudden Barometric Pressure Change Indications

Whenever the watch detects a significant change in air pressure readings (due to sudden ascent or descent, or to the passage of a low-pressure or high-pressure area), it will beep to let you know. An arrow will also flash on the display at this time if the watch is in the Barometer/Temperature Mode, or if it is in the Timekeeping Mode with the barometric pressure graph displayed. The arrow that appears shows the direction of the pressure change. These alerts are called “Barometric Pressure Change Indications”.

This indicator:

Means this:
dot_info_down_BARO_new

Sudden drop in pressure
dot_info_up_BARO_new

Sudden rise in pressure
dot_info_up_down_BARO_new

Sustained rise in pressure, shifting to a fall
dot_info_down_up_BARO_new

Sustained fall in pressure, shifting to a rise

Important!

To ensure correct barometric pressure change indicator 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. Enter the Barometer/Temperature Mode.

    2. Navigating Between Modes

  2. Hold down (B) for at least two seconds.

    3. If Barometric Pressure Change Indications are enabled, [INFO] [Hold] [On] flash on the display, and then [BARO] appears.

  3. To disable Barometric Pressure Change Indication, hold down (B) again for at least two seconds.

    4. [INFO] [Hold] [OFF] flash on the display, and then [BARO] disappears.

Note

If the Barometric Pressure Change Indication is enabled, readings are taken every two minutes even while the watch is not in the Barometer/Temperature Mode.

The Barometric Pressure Change Indication becomes disabled automatically 24 hours after it is enabled.

Time signal reception is disabled while Barometric Pressure Change Indication is turned on. Power saving is also disabled.

Power Saving Function

You will not be able to turn on Barometric Pressure Change Indication while the charge level of the watch’s battery is low.

Low battery power will also cause Barometric Pressure Change Indication to turn off.
