BACKLIGHT:
LCD SCREEN:
A/C adapter: The backlight is on continuously when operating the Forecast Station with the 5-volt a/c
adapter.
The LCD screen is split into 5 sections displaying the information for time, calendar, weather forecast,
indoor data, and outdoor data.
1. HIGH: The backlight is defaulted to HI (brightness) when the a/c adapter is in use.
2. LO: Press and release the LIGHT HI/LO button to dim the brightness of the backlight.
3. Press and release the LIGHT HI/LO button again to return to full strength (HIGH).
Note: When the Adapter is NOT in use, the High/Low backlight feature is not available.
1. OFF: Hold the HOLD ON/OFF button for 5 seconds, until the station beeps, to turn the backlight off to
sleep.
2. ON: Hold the HOLD ON/OFF button again until the station beeps, to turn the backlight on.
Note: When the backlight is off, press any button to activate the backlight for 8 seconds, and then it will
turn off again.
Battery power: Press and release the SNOOZE/LIGHT button and the backlight will show for 8 seconds,
when operating on batteries only.
WEATHER FORECAST ICONS:
The Forecast Station predicts weather condition for the next 12-hours based on the change of
atmospheric pressure. As weather conditions cannot be 100% correctly forecasted we cannot be
responsible for any loss caused by an incorrect forecast.
THIS STATION LEARNS!
Please allow 3-4 weeks for barometer calibration to generate an accurate forecast.
IMPORTANT: As the forecast station builds memory, it will compare the current average pressure to the
past forty day average pressure for increased accuracy. The longer the forecast station operates in one
location the more accurate the forecast icons will be.
MIN/MAX TEMPERATURE/HUMIDTY DATA: This Forecast Station features daily minimum and
maximum temperatures each day starting at midnight (12:00 AM). The clock automatically resets the
min/max temperatures at midnight (12:00 AM).
The icons forecast the weather in terms of getting better or worse and not necessarily sunny or rainy as
each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does
not mean that the product is faulty because it is not raining. It simply means that the air pressure has
dropped and the weather is expected to get worse but not necessarily rainy.
VIEW MIN/MAX:
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting
feature is estimated to have an accuracy level of about 75% due to the varying areas the Forecast Station
has been designed for use. In areas that experience sudden changes in weather (for example from sunny
to rain), the Forecast Station will be more accurate compared to use in areas where the weather is
stagnant most of the time (for example mostly sunny).
MAX: From a normal display press and release the MIN/MAX button once to view maximum
temperature and humidity values for Indoor and Outdoor data. The word MAX will appear next to the
indoor and outdoor temperature.
MIN: From a normal display press and release the MIN/MAX button twice to view minimum temperature
and humidity values for Indoor or Outdoor data. The word MIN will appear next to the indoor and
outdoor temperature.
RESET MIN/MAX: Hold the MIN/MAX button for 5 seconds to reset all indoor and outdoor minimum
and maximum values. (The clock automatically resets the min/max temperatures at midnight: 12:00
AM).
Note: If you are using multiple transmitters connected to the clock, all channels will reset at the same
time.

HEAT INDEX:
USE MULTIPLE OUTDOOR TRANSMITTERS:
Heat Index combines the effects of heat and humidity. It is the apparent temperature of how hot it feels to
a human being. When relative humidity increases, the air feels warmer than it actually is because your
body is less able to cool effectively by evaporation of perspiration.
The Forecast Station will accommodate up to three remote outdoor transmitters (TX14TH). The channel
selection button allows you to easily see the temperature in various locations:
outdoors, baby’s room, greenhouse, basement, etc.
Note: Heat index will be the same number as the temperature until the temperature is above 80 degrees
°F (26.7°C).
To connect multiple remote transmitters to the Forecast Station:
1. Remove the battery cover from all the transmitters (Leave battery covers
off until all transmitters are received by the Forecast Station).
2. Set the first outdoor transmitter to Channel 1 and insert 2-AA batteries.
3. Set the second outdoor transmitter to Channel 2 and insert 2-AA
batteries.
4. Set the third outdoor transmitter to Channel 3 and insert 2-AA batteries.
5. Press and hold CH button on Forecast Station until a beep sounds. The Forecast Station will search
for all outdoor transmitters.
View Heat Index: From a normal display press the HEAT/DEW button once and the Heat Index will show
(indoor/outdoor) instead of the ambient temperature. The words Heat Index will show near the indoor and
outdoor temperatures.
6. Press the TX button on the back of each outdoor transmitter to transmit RF signal.
7. When RF connection is established, the respective temperature & humidity for each of the selected
channels will appear on the main unit.
8. Allow the transmitters and the Forecast Station to stay 5-10 feet apart for 15 minutes to establish a
solid connection.
DEW POINT:
Dew point is the saturation point of the air, or the temperature to which the air has to be cooled in order to
create condensation. The higher the dew points, the higher the moisture content of the air at a given
temperature. Dew Point Temperature is the absolute measure of the moisture in the air at a given
temperature. Relative humidity is the relative measure of moisture in the air at a certain temperature.
9. Install the battery covers on each sensor.
10. After 15 minutes place the remote transmitters in appropriate locations (see “position the outdoor
transmitter”).
Press and release the CH button to view channel 1, 2 or 3 on the Forecast Station when multiple
transmitters are used.
Note: You cannot change channels if only one transmitter is connected.
Note: Dew Point is lower than the actual temperature.
CHANNEL SCROLL: Press and release the CH button until you see the word AUTO appear in the
outdoor data area. The Forecast Station will automatically rotate through the channels for all connected
transmitters.
Press and release the CH button to lock the Forecast Station into one channel. Then view channels
individually with a press of the CH button.
View Dew Point: From a normal display press the HEAT/DEW button twice and the Dew Point
temperature will show (indoor/outdoor) instead of the ambient temperature. The words Dew Point will
show near the indoor and outdoor temperatures.
