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 Digital Wall Clock. However, due to the nature
of the Earth’s Ionosphere, reception is very limited during daylight hours. The
Atomic Digital Wall Clock 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.

WWVB RECEPTION ICON with full signal strength will ap pe ar on screen

if the reception of atomic time is successful.

• The tower icon will show solid when the display has received the WWVB
signal.

• No tower icon displayed. The display was unable to receive a signal at this
time.

• Reposition the display for better signal reception or try again at bedtime.

• The display will start searching at UTC: 07:00 and if no reception on the first

attempt they will try again at 08:00, 09:00, 10:00, and 11:00. 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.

• Manual Search: Hold the -/TIME button to start a manual signal search.

Note: In case the Atomic Digital Wall Clock is not able to detect the WWVB
signal (disturbances, transmitting distance, etc.); the time can be manually
set.

Set up instructions step by step:
Step 1:

• Remove battery cover from the ou tdoor transmitter.

• Slide the battery cover down and lift off the back of the

transmitter

• Insert 2 NEW AA batteries (not included) into the transmitter.
Observe the correct polarity.

• Keep the LCD display and transmitter within 10 feet during setup.

• Note: Use Alkaline batteries

(or Lithium for temperatures below - 20°F / -28.8°C).

Step 2:

REMOTE TEMPERATURE SENSOR

• Remove battery cover from Atomic Clock, slide
tab down and pull out to remove the cover.

• Insert 2 NEW AA batteries (not included) into the
back of the Atomic Clock. Observe the correct
polarity (see marking inside the battery
compartment).Do NOT mix old and new
batteries.

• The Atomic Clock will display, time (12:00) date
(1/1) and indoor temperature.

• Within 3 minutes the Outdoor temperature should be displayed.

Trouble shooting:

• If after 3 minutes of waiting, the Outdoor temperature does not show up in the
designated area on the display, remove batteries from both units and start the
setup process again.

• For optimal reception performance, of the 433 MHz signal, the outdoor transmitter
should be placed within 200 feet (60 meters) from the Indoor LCD display.

TEMPERATURE TREND ICONS:

The indoor and outdoor temperature trend indicators are updated every 30
minutes. Trends represent temperature changes over the past three hours.

Temperature rising more than 2°F (1°C) in the past three hours

Temperature did not change more than 2°F (1°C) in the past three hours

Temperature falling more than 2°F (1°C) in the past three hours

The temperature trend indicators are shown next to the indoor temperature and
outdoor temperature readings.

OUTDOOR TRANSMITTER RECEPTION ICON:

• When the signal is successfully received from the outdoor transmitter, this icon will
be solid.

• This icon will flash when searching for the outdoor transmitter signal.

• If reception is not successful, the icon will not be shown in LCD.

WEATHER FORECAST ICONS:

The unit predicts weather condition of the next 12-hours based on the change of
atmospheric pressure. The weather forecast is about 70-75% correct. As weather
conditions cannot be 100% correctly forecasted we cannot be responsible for any
loss caused by an incorrect forecast.

The Icons displayed Forecasts the Weather in terms of getting better or worse and
not necessarily sunny or rainy as each icon indicates.

Note: After initial set-up, readings 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 therefore result in a more accurate
forecast.

WEATHER TENDENCY INDICATOR

Working together with the weather icons are the Weather Tendency
Indicators. When the indicator points upwards, it means that the Air-

pressure is incr e asing and the weather is expected to improve. When the
indicator points right the pressure is holding steady. When indicator points
downwards, the Air-pressure is falling and the weather is expected to become
worse. This is forecasting t h e ne x t 12 hours in the future.

POSITIONING THE OUTDOOR TRANSMITTER

The remote temperature transmitter should be mounted vertically to avoid damage.
Place both units in the desired shaded locations, and wait approximately 1-hour
before permanently mounting the transmitter to ensure that there is proper reception.
The outdoor temperature 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.

WALL MOUNT

Choose a location for the transmitter that is within range of the Atomic Digital Wall
Clock and under an overhang for accuracy.

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 sensor and into the wall.

• Tighten the screw to snug (do not over tighten).

To achieve a true temperature reading, mount where direct sunlight cannot reach
the outdoor transmitter. Mount the outdoor transmitter 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 20 0-feet (60 meters). O bstacles such as wa ll s,
windows, stucco, concrete, and large metal objects can reduce the range. Place the
transmitter at least 6 feet in the air to improve signal transmission.

POSITIONING THE CLOCK:

The Atomic Digital Wall Clock should be mounted near an exterior wall with the front
or back facing toward Ft. Collin Colorado for best WWVB reception. The display
should be six feet from other electronics or wireless devices in order to best receive
the outdoor temperature transmitter signal.

Wall Mount

Note: Always ensure that the atomic clock locks onto the screws before releasing.
CARE AND MAINTENANCE:

• Do Not Mix Old and New Batteries

Foldout Table Stand:

A foldout table stand is located on the back of the clock.
Pull the stand out from the bottom center edge of the atomic clock, below
the battery compartment. Once the foldout table stand is extended, place
the atomic clock in an appropriate location.

Use a straightedge to horizontally space three screw positions on a
wall to match the hanging holes on the back of the clock. Install three
mounting screws (not included) into a wall within transmission range—
leaving approximately 3/16 of an inch (5mm) extended from the wall.
Place the atomic clock onto the screws, using the hanging holes on
the backside.
Gently pull the atomic clock down to lock the screws into place.
