*The barometric pressure can be obtained from a calibrated barometer, or from the National Weather Service at www.nws.noaa.gov (enter your local zip code to
get the local barometric pressure). Note that the barometric pressure is in inches of mercury, multiply it by 25.4 to convert to mmHg.
Obtain the local barometric pressure in mmHg.*

10 seconds. While pressing and holding the
