• Over 200 FT. wireless transmission range

INITIAL SET UP:

Adapter on the main unit with batteries or a/c adapter and set the time zone &

weather icon:

 The Time Zone will flash EST. Press and release the UP or DOWN button to

select the Time Zone. Press and release the SET button.

 The Weather Forecast Icons will flash. Press and release the UP or DOWN

button to select the forecast Icon that represents your current local weather.

Press and release the SET button to confirm.

 The Temperature area will flash as the display searches for a signal from

the outdoor transmitter.

 Insert fresh alkaline batteries into the transmitter, observing the correct

polarity Press the TX button to send a signal after the display is powered up.

Keep the transmitter 5-10 feet from the weather station.

 Within 3 minutes the station will beep and the outdoor temperature should be

displayed on the Weather station. If the outdoor temperature is not displayed

after 3 minutes hold the SEARCH button on the main unit to search for

outdoor sensor. Then press the TX button again on the sensor to send

signal. If that doesn’t work, remove power from both units and start again

from the beginning.

 To ensure sufficient 434 MHz transmission, the outdoor transmitter should be

placed a distance of no more than 200 feet (60 meters, open air) from the

Color Weather station.

INSTALL BATTERIES OR A/C POWER ADAPTER INTO THE WEATHER

STATION:

A/C power adapter:

Plug enclosed 6-volt a/c power adapter into a wall outlet, then into the weather

station.

Batteries:

 Remove battery: Slide tab to the left and pull out to remove battery

cover.

 Install three fresh AAA alkaline batteries according to the polarity

markings.

 Do Not Mix Old and New Batteries

 Do Not Mix Alkaline, 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 powering up

the weather station again.

INSTALL BATTERIES IN THE TRANSMITTER:

 Remove screws and the battery

cover from the back of the

transmitter with a small screwdriver.

 Insert two fresh AAA alkaline

batteries into the transmitter,

observing the correct polarity (see

marking inside battery

compartment).

 Keep transmitter 5-10 ft. from the

weather station.

WWVB RADIO CONTROLLED TIME

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

atomic weather station. However, due to the nature of the Earth’s Ionosphere,

reception is very limited during daylight hours. The atomic weather station will

search for a signal every night when reception is best. The WWVB radio station

derives its signal from the NIST atomic weather station 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 weather station regulates the WWVB

transmitter.

WWVB RECEPTION icon with full signal strength will appear on screen if the

reception of atomic time is successful. The atomic weather station will have a daily

synchronization at 02:03 and 03:03 everyday. Each reception cycle is minimum

2.5 minutes and maximum 10 minutes.

In normal mode, press the RCC button until the reception icon appears to enforce

searching of radio-controlled clock signal. If this icon disappears afterwards, radio

time signal is not available at the moment.
