INITIAL SET UP:
Note: The Forecast Station will display the fisherman icon, lines etc., before batteries are installed.
These items are painted on the screen.
1. Insert 3 AA batteries (not included) into the Forecast station (see Install Batteries in the Forecast
Station). The Forecast Station will light up and show, pressure, indoor temperature, humidity and
channel 1.
2. Insert 2 fresh AA batteries into the transmitter, observing the correct polarity (see Install Batteries in
the Outdoor Transmitter).
Note: The CH switch is set to Channel 1 by default. Confirm channel 1 is selected.
3. Keep the transmitter 5-10 feet from the Forecast station for 15 minutes to establish a good
connection.
4. Within 3 minutes the station will beep and the outdoor temperature should be shown on the Forecast
station. If the outdoor temperature does not show after 3 minutes remove power from the transmitter
and the Forecast station for 60 seconds and start again from step 1.
5. If the outdoor temperature does not show up after a second attempt, please slide open the battery
cover of the outdoor transmitter to reveal the TX button. Push down on the TX button for 3 seconds to
send a wireless signal to the Forecast Station.
6. Hold the CH button on the forecast station to start the search for the transmitter signal.
7. For optimum 433 MHz transmission, the outdoor transmitter should be placed a distance of no more
than 200 feet (60 meters, open air) from the Forecast station.

WWVB RADIO CONTROLLED TIME
The NIST radio station, WWVB, is located in Ft. Collins, and transmits the exact time signal continuously
throughout the United States at 60 kHz. The signal can be received up to 2,000 miles away through the
internal antenna in the Forecast station. However, due to the nature of the Earth’s Ionosphere, reception
is very limited during daylight hours. The Forecast station will search for a signal every night when
reception is best. The WWVB radio station derives its signal from the NIST Atomic Clock in Boulder,
Colorado. A team of atomic physicists continually measures every second of every day to an accuracy of
ten billionths of a second a day. These physicists have created an international standard, measuring a
second as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. This atomic clock regulates the
WWVB transmitter.
WWVB RECEPTION ICON with full signal strength will appear on screen in front of the date when
the reception of time is successful.
The tower icon will show solid when the Forecast station has received the WWVB signal.
No tower icon is shown. The Forecast station was unable to receive a signal at this time.
Reposition the Forecast station for better signal reception or try again at bedtime.
The Forecast station will start searching at UTC: 07:00 and if no reception on the first attempt they
will try again at 08:00, 09:00 and 10:00. Each attempt will be at least 2 minutes and the most will be
10 minutes.
If there is no signal or too much interference the receiver will only be on for 2 minutes.
If the signal is good it may catch a signal in ABOUT 2-3 minutes.
If the signal is marginal it will try to catch a signal for up to 10 minutes.
IMPORTANT: When operating on a/c power, the backlight and USB charge port will turn off while the
Forecast station searches for the WWVB signal, to avoid interference. Both features will return after
the 2-10 minute search which occurs during the late night or early morning hours.
Note: In case the Forecast station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.); the time may be manually set.
WWVB Manual Signal Search:
Normal mode: Hold the + and - buttons together for 3 seconds to enter manual search.
Reception mode: Hold the + and - buttons together for 3 seconds to exit searching for the WWVB signal.
Note: In case the Wireless Forecast Station is not able to detect the WWVB-signal (disturbances,
transmitting distance, etc.); the time can be manually set by following the program menu.
Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of
6 feet (2 meters).
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened.
In extreme cases, please place the unit close to a window and/ or point its front or back towards the
Fort Collins, Colorado, transmitter.
During nighttime, the atmospheric disturbances are usually less severe and reception is possible in
most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.
Note: In case the Forecast station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time and date can be manually set (see “program menu”).

After a short calculation time, the forecast station shows the times for sunrise and sunset, moon phase
and lunar tide.
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. Not daily high
and low tides. When the forecast station states high tide, the tides will be higher than usual, etc.
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%
