Forecast Icons Inaccurate; Barometric Pressure - La Crosse Technology 308-1417V3 Faqs

• Hawaiian
3. Check that ATOMIC is ON. This must be ON to receive a WWVB atomic time signal.
4. Check that the DST indicator is ON. If the indicator is OFF the weather station will not change into or out
of Daylight Saving Time.
5. Batteries dated earlier than 6 years from now may still work, but may be unstable in performance.
Note: Without proper batteries, the antenna will have a harder time picking up the signal.
• For information about WWVB visit:
The forecast icons are determined by the station's barometric pressure reading. Please allow 7-10 days for
barometric calibration. Six forecast icons use changing atmospheric pressure to predict weather conditions
for the next 12-hours with 70-75% accuracy.
When Outdoor temperature is below 32˚F and the forecast is RAIN or T-STORM, the station will display
SNOW.
Forecast Icons:
• Sunny
• Partly Sunny
• Cloudy
• Rain
• T-Storm
• Snow
• The weather station calibrates barometric pressure based on its location over a period of time to
generate an accurate, personal forecast. Please allow 7-10 days for barometer calibration.
• The station samples the barometric pressure every twelve minutes. These samples are averaged hourly
and daily then stored in nonvolatile memory. The three-hour pressure icon change is based off the last
four average hourly readings.
• IMPORTANT: As the weather station builds memory, it will compare the current average pressure to the
past forty day average pressure for increased accuracy. The longer the weather station operates in one
location the more accurate the forecast icons will be.
• A sensor in the forecast station, not the outdoor sensor, reads the Barometric Pressure. A significant
difference in pressure inside and pressure outside would create a vacuum.
• The numeric pressure value adjusts automatically as the forecast station reads changes in air pressure.
• La Crosse Technology products will not read pressure correctly above 6200 ft. in elevation.
• Loss of Pressure is often a power-related problem, and it can be resolved by following these steps:
o Remove power from the display for 2 hours. Press any button 20 times with power removed.
