WWVB Radio-controlled Time Signal
The radio controlled weather station searches for, and periodically synchronizes to, the NIST (National Institute of
Standards and Technology) atomic clock signal transmitted from Ft. Collins, Colorado, throughout the entire continental
United States.
The NIST radio station, WWVB, is located in Ft. Collins, Colorado 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 weather station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight
hours. The weather station will search for a signal every night when reception is best.
During nighttime hours, atmospheric conditions improve radio signal reception. A single daily reception is sufficient
enough to keep the clock accuracy within milliseconds.
The weather station should be positioned 6 feet (2 meters) from interference sources such as a TVs, computers,
microwaves, etc.
The signal reception is weakened within concrete walls found in basements or office buildings. Place the weather
station near the window for best reception.
It takes between 24 and 72 hours for the clock to receive an atomic time signal reception
Once the atomic time signal is received, the date and time will be set automatically, and the icon will appear. The weather
station is programmed to search for the atomic time signal daily each hour between 1:00 am and 4:30 am. Once the time
signal has been successfully received, the time and date will be updated automatically.
Manual Signal Search

All the bar charts are read from left to right.
The left is the oldest history data.
Reading from left to right indicates the rise and fall of the reading.
The bar chart will constantly scroll to avoid LCD burnout.
Weather Forecast Icons
The weather forecasting feature is estimated to be 70% accurate. The weather forecast is based solely upon the change
of air pressure over time. The icons are predicting 12-24 hours in the future, not current conditions. It may be sunny out
your window, but the pressure is falling so the forecast station will show clouds with rain icon. The SUNNY icon indicates
clear weather, even when displayed during the night-time.The icons displayed forecast the weather in terms of getting
better or worse, and not necessarily sunny or rainy as each icon indicates.
Note: After initial set-up, icons for weather forecasts should be disregarded for the next 48-60 hours. This will allow
sufficient time for the weather station to collect air pressure data at a constant altitude and result in a more accurate
forecast.
Model: WS-1517

Download from Www.Somanuals.com. All Manuals Search And Download.
For every sudden or significant change in the air pressure, the forecast icons will update accordingly to represent the
change in weather. If the icons do not change, then it means either the air pressure has not changed or the change has
been too slow for the weather station to register.
If the weather station is moved to another location significantly higher or lower than its initial standing point (for example:
from the ground floor to the upper floors of a house), disregard the weather forecast for the next 48-60 hours. By doing
this, the weather station will not mistake the new location as being a possible change in air pressure, when really it is due
to the slight change of altitude.
Moon Phase
The LCD Moon phase is divided by 6 sections, showing a total of 12 phases of the moon. The moon phase is based on
the year, month and date, set manually or set by the WWVB signal.
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. We see
half of the moon illuminated and half is in shadow.
Waxing means growing or expanding illumination which occurs 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.
View the Moon Phase History
The weather station indicates the current moon phase. You can view moon phase history and forecast for up to 39 days in
one day increments. The history will show in the History Window with a + or – number indicating the days of change. The
moon icon itself will also change to match the history reading.

When operating with the optional A/C power cord, the weather station backlight can be turned ON,
OFF or automatic (depending on light conditions).
AUTO: the backlight will be off in when there is adequate light, and will come on automatically in
low light conditions.
ON: the backlight will be on constantly when using A/C power.
OFF: the backlight will remain off unless the LIGHT button is pressed.
Note: For continuous backlight control the A/C adaptor (included) must be plugged in.
Backlight sensor sensitivity can be adjusted to high or low using the switch, located on the back of the weather station.
When operating on battery power alone, the backlight can be activated for three seconds by pressing the LIGHT button on
top of the weather station.
Memory Reset Procedure
Note: This will completely reset all of the stored memory in the weather station.
1. Hold SNOOZE and UP buttons for four (4) seconds so the backlight will flash.
2. Press the SET button which will clear the memory–the weather station will start beeping with a one second delay.
3. Wait until the beeping stops.
4. Disconnect weather station from the A/C adapter. Remove batteries from the back or the weather station (optional) if
installed.
5. Wait at least 10 seconds and then reinsert the A/C adapter and batteries.
IMPORTANT: Do not press any buttons during the setup process, which take 5-15 minutes. During this time, the
weather station will flash the pressure icon and InHg (inches of mercury). Setup is completed when the weather
station shows default settings for pressure and altitude (sea level), indoor/outdoor temperature and humidity, wind and
rain readings, etc.
6. Follow the program menu to set language and city code then any custom settings desired.
Changing Batteries
The battery status of each remote sensor is checked every hour. If the low battery indicator lights up, replace the
batteries in the corresponding sensor.
Do Not Mix Old and New Batteries
Do Not Mix Alkaline, Standard, Lithium or Rechargeable Batteries
Weather Station
With A/C power cord: Connect the optional 7.5V A/C adaptor to the weather station to avoid losing any data.
Remove the battery compartment door at the back and replace all batteries.
Replace the battery compartment door.
Without A/C power cord:
Remove the battery compartment door at the back and replace all batteries.
Replace the battery compartment door.
Do not press any buttons during the setup process, which takes 5-15 minutes. During this time, the weather station
will flash the pressure icon and InHg (inches of mercury). Setup is completed when the weather station shows default
settings for pressure and altitude (sea level), indoor/outdoor temperature and humidity, wind and rain readings, etc.
Set language and city code.

When the batteries are properly installed, the remote sensor will resume sending signals to the weather station.
Hold the DOWN arrow button for 4–5 seconds on the weather station to search for the remote sensors.
Positioning Sensors Outside
Each sensor reads to the weather station independently.
Consider the location of the weather station in the house and in relation to each sensor outside.
The transmission range is 100 ft (30 m) open air, between each sensor and the weather station.
Obstacles such as trees, walls, concrete and large metal objects can reduce the range by one-half.
Place sensors and weather station in desired locations, and wait approximately 30 minutes before permanently
mounting to ensure that there is proper reception.
Wind
For most accurate wind readings, mount the wind sensor as the highest item in the area with a 50 foot clearance in all
directions (avoid tall trees, buildings or other obstructions that may block or reflect the wind).
Cup should be on the bottom.
Use 4 screws to mount the wind sensor vertically on a piece of wood about 3 inches wide.
Be sure the metal mast holder faces north so the direction will read correctly.
Roof Mounting: In most cases, at least 6 ft above the peak of the roof (or more) is required for accurate readings.
(Avoid tall trees or other obstructions that may block or reflect the wind).

Ground Mounting: Place at least 6 feet up on a pole in an open area. Higher is better. The wind sensor should be
the highest item in the immediate area. Mount the wind sensor away from all obstacles that will block wind activity,
such as trees and houses.
Rain
Make sure that the rain sensor is level. Look inside; there is a built-in level to assist in mounting. Make sure the
bubble is centered in the level.
Place the protective screen over the top to protect the rain sensor from the debris.
Where practical, mount the rain sensor in place with wood screws (not included).
Make sure that the rain sensor is in open area where precipitation falls directly into the sensor’s bucket, ideally 3-6
feet above the ground.
Note: The rain sensor will need to be cleaned of debris on a regular basis. Mount in an accessible area.
The rain sensor should be placed in an open area away from the walls, fences, trees and other coverings
this may reduce the amount of rain falling into the bucket. Additionally, trees and rooftops may be sources
of pollen and debris that may clog the rain sensor.
To avoid the rain shadow effects, place the rain sensor horizontally, at a distance about two to four times the height of
any nearby obstruction.
Be aware of other wireless rain gauges in the area that may cause interference.
The Rain Gauge is self-emptying and can be left out all year or stored in the winter. If stored for the winter, remove the
batteries to avoid leakage.
Thermo-hygro
The remote thermo-hygro sensor should be placed in the area with a free air circulation and sheltered from direct
sunlight and an extreme weather conditions.
While the thermo-hygro sensor is weather resistant, avoid submersion in water or snow.
We recommend that you mount the outdoor temperature sensor on an outside North-facing wall.
The remote thermo-hygro sensor can stand vertically on a flat surface or mounted on the wall in vertical position
Use screws when mounting the thermo-hygro sensor on the wall
Avoid placing the thermo-hygro sensor near sources of heat such as chimneys and heating elements.
Avoid areas that collect or radiate heat from the sun, such as metal, brick/concrete structures, paving or patio decks.
Position the Weather Station
Make sure that the weather station is locating within the operating range of all remote sensors.
Mount the remote sensors within the line of sight of the weather station.
Transmission range may be affected by trees, metal structures and electronic appliances.
Test reception before permanently mounting all the remote sensors.
Mount near an exterior wall with the front or back facing toward Ft. Collins, Colorado for best WWVB reception.
Avoid placing the weather station in the following areas:
Direct sunlight and surfaces emitting and radiating heat, such as heating ducts or air conditioners.
Areas with interference from the wireless devices (such as cordless phones, radio headsets, baby listening devices,
etc.) and electronic appliances.
Care and Maintenance
Do not mix old and new batteries
Do not mix Alkaline, Standard, Lithium or Rechargeable Batteries
