THIS STATION LEARNS!

Please allow 3-4 weeks for barometer calibration to generate an accurate forecast.

• Sits on desktop or tabletop

• 3 "AA" Alkaline batteries (not included) OR optional 5.0V AC adapter (included)

INITIAL SET UP:

1. Insert A/C adapter into the wall outlet then into the Weather Station or insert 3 AA batteries (not
included) into the Weather Station (see Power the Weather Station). The Weather Station display
will light up and show, 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 Weather 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 Weather
Station. If the outdoor temperature does not show after 3 minutes remove power from the transmitter
and the Weather Station for 60 seconds and start again from step 1.

5. 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 Weather Station.

IMPORTANT: When operating on a/c power, to avoid interference, the backlight and USB charge port
will turn off for 2-10 minutes while the Weather Station searches for the WWVB signal. Both features will
return after the 2-10 minute search.

POWER THE WEATHER STATION:

Battery

Compartment

5-Volt a/c adapter

The Weather Station can be powered by the 5-volt a/c adapter or batteries.

A/C power adapter:

Insert enclosed 5-volt a/c power adapter into a wall outlet, then into the Weather Station.

Batteries:

1. Remove battery cover: Slide tab to the right and pull out to remove battery cover.

2. Install three fresh AA batteries according to the polarity markings.

Do Not Mix Old and New Batteries
Do Not Mix Alkaline, Lithium, Standard, or Rechargeable Batteries

If the Weather Station does not display indoor temperature after 60 seconds, remove adapter and
batteries, and wait for at least 60 seconds before repeating the setup process.

INSTALL BATTERIES IN THE OUTDOOR TRANSMITTER:

1. Slide the battery cover down, then lift off the back of the transmitter.
Note: Be careful not to break the tabs on the battery cover.

2. Confirm the channel selector switch is on channel 1.

3. Insert two fresh AA batteries into the transmitter. Observe the correct
polarity (see marking inside battery compartment).

4. Keep transmitter 5-10 ft. from the Weather Station during setup.

5. After 15 minutes, if the outdoor temperature shows on the Weather
Station, you can move the outdoor transmitter outside to a shaded
location within range of the Weather 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 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. 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 Weather Station has received the WWVB signal.
No tower icon is shown. The Weather Station was unable to receive a signal at this time.
Reposition the Weather Station for better signal reception or try again at bedtime.
The Weather 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

Weather 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 Weather Station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.); the time may be manually set.

Manual Signal Search: In normal mode, hold the RCC button until the reception icon appears to force a
search of the WWVB signal. The WWVB icon will flash during the search. If this icon disappears after

the 2-minute search, the radio time signal is not available at the moment.

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 Weather Station is not able to detect the WWVB-signal (disturbances, transmitting
distance, etc.), the time and date can be manually set (see “program menu”).
