Pressure Operation, Select Pressure Units of Measure

PRESSURE OPERATION

The pressure window displays: current barometric pressure, sea level pressure, and weather

forecast. The information contains a number of historical statistics: pressure/ temperature/ humidity history bar-chart for the past 24 hours

Pressure can be measured in inHg, hPa/mBar or mmHg, and altitude is determined in either meters or feet.

IMPORTANT: There are three viewing options available: barometric pressure SEA LEVEL or LOCAL and ALTITUDE. Local pressure is a measured value (can’t be adjusted) while Sea Level & Altitude are variables that you can enter. It is advisable to select and program only one of the variables and to allow the unit to calculate the third value.

The unit is designed to measure pressure changes at your specific location, when LOCAL barometric pressure is selected. Information for programming your unit, with either Altitude or Sea Level values, may be obtained from GPS readings, online from the Internet, etc.

SEA LEVEL barometric pressure provides you with information about pressure changes at lower elevations in your surrounding area. The SEA LEVEL pressure value can be set to match your local metro area weather information. (Sources – local TV or radio station, etc.)

SETTING INITIAL PRESSURE PARAMETERS

IMPORTANT: Allow the unit to set without touching ANY buttons for about 6-8 minutes during the main unit initial set up. This will give the unit time to synchronize with remotes, stabilize pressure readings and settle with default settings.

SELECT PRESSURE UNITS OF MEASURE

Press UP (? ) or DOWN (? ),as needed, until the pressure icon “PRESSURE”, to the left of the barometric pressure value, begins to flash.

•Press MODE button, to toggle through selections until “SEA LEVEL” or “LOCAL” barometric pressure is displayed.

•Press and hold MEM/ HISTORY button to enter the pressure unit selection mode. Press the UP (? ) or DOWN (? ) button to select the preferred units of measure for pressure:

inHG (English), hPa/mBar (scientific) or mmHg (metric)

•Press MEM/ HISTORY to confirm your selection. Then press MODE to move to the ALTITUDE unit selection mode. Press the UP (? ) or DOWN (? ) button to select pressure unit as FEET or METER.

•Press MEM/ HISTORY to confirm and hold MODE to move to the ALTITUDE value selection mode.

•Press UP (? ) or DOWN (? ) to select or adjust the altitude value to your location. (Press and hold either button for accelerated digit advance)

•Press MODE to confirm the programming selection.

(NOTE: The unit will automatically exit programming mode if it does not detect a button press after 2 minutes.)

VIEWING PRESSURE AND ALTITUDE INFORMATION

To view pressure or altitude information, press MODE button. The display will alternate between the sea level pressure, local pressure and local altitude screens.

PROGRAMMING SEA LEVEL PRESSURE (not required if you did altitude)

•Press and hold MODE, until the barometric pressure digits are flashing.

•Enter the desired sea level pressure value by pressing UP (? ) or DOWN (? ) buttons. (Press and hold either button for accelerated digit advance.)

•Press MODE, to confirm sea level value selection.
