Model: 308-1451H www.lacrossetechnology.com/support 6
Note: When DST is in affect the forecast station will need to receive the WWVB time signal to make the
adjustment for DST. The WWVB signal includes an embedded bit to tell the station to adjust for DST. Until that
signal is received the first time, the sunrise/sunset times will be one hour off.
Tide
The tides reflected on this station are based on the ebb and neap tides of the lunar month rather than the daily
high and low tides. When the sun, moon and earth are lined up at new and full phases of the moon, tides will be
higher. When the moon is at right angles to the sun and Earth at the first and last quarter, the tides are weaker.
Full & new moon = spring tide (TIDE HI)
Quarter = neap tide (TIDE LO)
Other = mean water level (TIDE MID)
Moon Phase
The LCD Moon phase is divided by 6
sections, showing a total of 12 phases of
the moon.
Note: With the moon shown against a
light colored background, the phases will
show opposite to a paper calendar. The
segments that are highlighted portray the
part of the moon that is lit. For instance,
the moon will be blank during a new
moon and dark during a full moon.
New Moon occurs when the moon is between the earth and sun so the illuminated portion of the moon is on
the back side facing the sun and we cannot see it. After a new moon, the illuminated (visible) portion will
increase or wax until the full moon occurs.
Full Moon occurs when the earth, moon and sun are in approximate alignment, with the moon and the sun
on opposite sides of the earth. The illuminated portion of the moon faces the earth, giving us complete
visibility of one side of the entire moon. After a full moon, the illuminated portion will decrease or wane until
the new moon occurs.
First Quarter and Last Quarter moons occur when the moon is at a 90 degree angle to the earth and sun.
So we see half of the moon illuminated and half is in shadow.
Waxing means growing or expanding illumination and happens after a new moon.
Waning means decreasing illumination and occurs after a full moon.
Crescent refers to the moon being less than half illuminated. Crescents can be waning or waxing.
Gibbous describes a moon phase when more than half is illuminated. Gibbous can be waxing or waning.
Comfort Statement
The comfort statement is based on the indoor humidity.
WET: Humidity is above 64%
COMFORTABLE: Humidity is between 43% and 64%
DRY: Humidity is below 42%

Pressure Readings
Absolute Barometric Pressure Number
Barometric pressure is read by the forecast station. The numeric pressure value adjusts automatically as the
forecast station reads changes in air pressure. Since this number is absolute pressure, it may not be the same
as a local reporting station that reads in relative pressure.
Note: The number cannot be calibrated.
Absolute Pressure is measured in a vacuum without the influences of terrain, weather, water, foliage and
elevation. The air pressure it would be consistent at every elevation and decrease as it went higher.
Relative Pressure is a combination of air pressure and altitude. Relative air pressure will make readings in
local areas relative to each other to allow for proper forecasting.

Pressure Unit of Measurement (InHg or hPa)
Hold the HISTORY button for 5 seconds to switch from InHg (inches or mercury) or
hPa (Hectopascal) for the numeric pressure display and the pressure graph.
Inches of Mercury is common for weather reports and aviation in the United States.
Hectopascal is equivalent to millibar and commonly used to measure atmospheric pressure outside the
United States.
Pressure History
Press and release the HISTORY button to view the past 12-hours of numeric pressure
history.
In the small box to the right of the numeric pressure a number from 0 to -12 will
appear.
0 is current pressure. -1 through -12 reflects the history in one-hour increments.
Note: The history graph and forecast icons will not change when you view pressure history.
Pressure History Graph
The bar chart indicates the air pressure history trend over the last 12 hours in 5
steps, 0h, -1h, -2h, -3h, -6h & -12h.
The columns represent the change in pressure readings (InHg or hPa) at
specific times.
The “0” in the middle of this scale is equal to the current pressure and each
bar represents how high or low the past pressure was compared to the
current pressure.
Read the graph from left to right. If the bars are rising, it means that the weather will improve. If the bars go
down, it means the air pressure has dropped and the weather is expected to degrade.
Note: The bar graph will scroll continually to prevent LCD burnout.
MIN/MAX Data
The forecast station will show the daily minimum and maximum temperatures each day starting at midnight
(12:00 AM). The forecast station automatically resets the min/max temperatures at midnight (12:00 AM).
View MIN/MAX data: Press and release the MAX/MIN button to view the Maximum, Minimum,
then Current Indoor and Outdoor Temperatures.
Multiple Sensors: Press and release the CH button to select the desired outdoor channel to view the
Minimum and Maximum Outdoor Temperatures. Press and release the MAX/MIN button to view the
Maximum, Minimum then Current Temperatures for that channel.
Reset all MIN/MAX data: Hold the MAX/MIN button for 5 seconds and the Indoor and all Outdoor Minimum
and Maximum Temperatures will be reset manually to Current temperatures.
Low Battery Indicator
When the low battery icon appears in the indoor (IN) reading section, replace the batteries in the
forecast station.
When the low battery icon appears in the outdoor (OUT) readings section, replace the batteries

Weather Forecast & Hunter Icons
Weather Forecast Icons (Sun, Partial Sun, Clouds, Rain and Snow)
The icons in the top right corner shown below forecast the weather for the next 12-24 hours. The icon is a prediction of the
weather in terms of getting better or worse based on rising and falling barometric pressure.
INTELLIGENT WEATHER FORECAST
This station learns. Please allow 3 to 4 weeks for barometric calibration. This will ensure an accurate personal forecast for
your location.
Weather Tendency Indicators (up and down arrows)
Working together with the weather forecast icons are the weather tendency indicators. When the indicator
points upwards, the Air Pressure is increasing; weather is expected to improve. When indicator points
downwards, Air Pressure is falling; weather is expected to degrade. An arrow to the right means no
change.
Hunter Icon Clothing Index Based on Outdoor Temperature
The hunter’s clothing updates with changes in the measured Outdoor Temperature from the sensor on
channel 1.
The hunter icon represents CURRENT TRENDS in Temperature.
