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%

Backlight

Press the SNOOZE/LIGHT button on the top of the forecast station to activate the blue
LED backlight for 5 seconds.
