Module No. 3515

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:
	Sudden drop in pressure
	Sudden rise in pressure
	Sustained rise in pressure, shifting to a fall
	Sustained fall in pressure, shifting to a rise

1. Display the current time screen.

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



3. Press (C).

This displays the current barometric pressure and temperature.

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

This displays the barometer/temperature measurement setting screen.



5. Use (A) and (D) to move the pointer to [BAROMETER INFORMATION].

6. Press (C).

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

[ON]	Enables the barometric pressure change indication.
[OFF]	Disables the barometric pressure change indication.

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

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