To Set the Barometric Pressure
1. Find the current local barometric pressure.
You may be able to get local barometric pressure readings fromTV and radio
weather reports, or your local airport control tower.
Barometric pressure readings are also available on the internet.
• For baromeric pressure readings in the U.S., go to http://iwin.nws.noaa.gov
Choose "Text version" and then choose "State Data".
• For barometric pressure readings outside the U.S., a good place to check is
www.wmo.ch , click on "Meteorological Information". Choose "WMO Members
with Web & Gopher Server".
2. Press BAR.
A barometric pressure reading and the symbol IN (or MM or MB) appear on the
display.
3. Press UNITS until the desired unit of measure (IN, MM or MB) appears.
4. Press ENTER to set the current barometric pressure. (see "Using the Enter Key" on
page 16 for instructions).
Note: When you enter barometric pressure in millibars, there is a fifth digit—a 1 at the far left. This
number changes first when you begin changing barometric pressure. The 1 flashes on and off as
you hold ENTER down. Release ENTER when you see the 1 for a barometric pressure of
1000.0 mb or more. Release ENTER when the 1 is not showing for a barometric pressure below
1000.0 mb.
5. Press BAR to save the setting.
The number you entered appears as the current barometric pressure.
Note: To prevent accidental changing of the barometric pressure once it has been set, hold down the
ENTER key for at least eight seconds before the first digit on the left begins to change.
Barometric Pressure settings drifts over time so, every 4-6 months, check your
barometer setting to ensure it is correct.
