Maximum Temperatures will be reset.
The temperature area will show dashes briefly then return to current temperatures.
Heat Index and Dew Point Temperature
Heat Index
Heat Index combines the effects of heat and humidity. It is the apparent temperature of how hot it feels to
a human being. As humidity increases, the body is unable to cool effectively; therefore, the temperature
will feel warmer.
View Heat Index: From a normal display, press the HEAT/DEW button once and Heat Index will show
instead of the outdoor ambient temperature.
Note: Heat index will be the same number as the temperature until the outdoor temperature is above 80
°F (26.7°C).
Dew Point Temperature
Dew Point Temperature is the saturation point of the air, or the temperature to which the air has to cool in
order to create condensation. The higher the dew points, the higher the moisture content of the air at a
given temperature.
View Dew Point Temperature: From a normal display, press the HEAT/DEW button twice and Dew
Point will show instead of the outdoor ambient temperature. The words Dew Point will show near outdoor
temperatures.
Note: Dew Point is lower than the actual temperature.

Outdoor Temperature/Humidity Flashing
1. Low battery icon present in the outdoor temperature area:
Change batteries in the transmitter and press the TX button.
Hold the HEAT/DEW button for three seconds and the weather station will search for the outdoor
transmitter again.
2. End of Transmission Range:
Move the transmitter closer to the weather station.
Avoid obstructions in the signal path.
Keep transmitter and weather station away from electronics.
Moon Phase
The Moon Phase is based on the date manually set on the weather station. The moon is divided by 6
sections, showing a total of 12 phases of the moon.
Waxing indicates growing or expanding illumination and happens after a new moon.
Waning indicates 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.
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
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 the other half is in shadow.

Position the Weather Station
Choose a location for the weather station that is within range of the outdoor transmitter. The
weather station has a built in base stand to sit on a table or desk.
Choose a location 6 feet or more from electronics such as cordless phones, gaming systems,
televisions, microwaves, routers, baby monitors, etc., which can prevent signal reception.
Be aware of electrical wires and plumbing within a wall.
Best reception is achieved when the front or the back of the weather station is facing the
outdoor transmitter. This allows a larger portion of the antenna to receive a signal.
Position the Outdoor Transmitter
Once the weather station shows the outdoor temperature/humidity, place it and the transmitter in the
desired locations and wait approximately one-hour before permanently mounting the transmitter to ensure
that there is proper reception. The transmitter should be mounted vertically, in a shaded, protected area,
at least 6 feet from the ground to avoid damage and ensure accurate readings. The transmitter is water
resistant, not waterproof and should not be placed anywhere it will become submerged in water or subject
to standing water or snow. To achieve a true temperature/humidity reading, mount where direct sunlight
cannot reach the outdoor transmitter. Mount on a North-facing wall or in any well shaded area. Under an
eave or deck rail work well. The maximum transmitting range in open air is over 200 feet (60 meters).
Obstacles such as walls, windows, stucco, concrete, and large metal objects can reduce the range.
transmission.
Option 1:
Install one mounting screw (included) into a wall leaving approximately ½ of an inch
(12.7mm) extended.
Place the transmitter onto the screw, using the hanging hole on the backside.
Gently pull the transmitter down to lock the screw into place.
Option 2:
Insert the mounting screw through the front of the transmitter and into the wall.
Tighten the screw to snug (do not over tighten).
