Setting the Sea Level

Barometric Pressure

No matter where you are, barometric pressure is measured using the current sea level barometric pressure. This way, meteorologists (and you!) can easily compare measurements from locations at different altitudes.

Note: To obtain the current sea level barometric pressure in your area, contact the nearest airport or go to http:// www.nws.noaa.gov and select current weather conditions for the closest location to you in your state.

1.Repeatedly press BARO until ￿￿￿

￿￿￿￿￿ appears.

2.Hold down SET for about 2 seconds until the previous sea level pressure setting flashes.

3.Press or to set the sea level pres- sure.

4.Press SET to store the setting.

Using the Barometric

Pressure-Drop Alarm

You can set the monitor to sound an alarm when the current barometric pressure drops to the condition relevant to a programmed setting. For example, you can set the monitor to sound an alarm if the current barometric pressure drops .03 inch below the level you specify. Each time the barometric pressure changes and meets the set condition, ￿￿￿￿￿

flashes and the monitor sounds an alarm for about 1 minute. To silence the alarm sooner, press any key.

Note: If you press a key to silence the alarm, the alarm stops sounding, but continues to flash until the alarm condition is no longer met.

To view the current barometric pressure-

drop alarm setting, press BARO, then press ALARM. The barometric pressure-drop alarm setting and ￿￿￿￿￿ appear.

Note: ￿￿￿￿ appears when no alarm condition is set.

Setting the Barometric

Pressure-Drop Alarm

1.Press BARO.

2.Repeatedly press ALARM until ￿￿￿￿￿

appears.

3.Hold down SET for about 2 seconds until the last set pressure-drop alarm condi- tion flashes.

4.Repeatedly press (or hold down) or until the monitor shows the desired setting.

5.Press SET to store the setting.

Note: If you do not press any button for about 60 seconds, the monitor returns to the current barometric reading display. To continue programming, start over at Step 2.

Clearing the Barometric Pressure-Drop Alarm Setting

To clear the barometric pressure-drop alarm condition so the alarm does not sound, press BARO. Repeatedly press ALARM until

￿￿￿￿￿appears, then repeatedly press until ￿￿￿￿ appears.
