INITIAL SET UP:
1. Insert 2 AA batteries (not included) into the Digital Atomic Clock (see Install Batteries in the Digital Atomic Clock).
The Digital Atomic Clock then shows time and indoor temperature.
2. Insert 2 fresh AA batteries into the transmitter, observing the correct polarity (see Install Batteries in the Outdoor
Transmitter).
Do Not Mix Old and New Batteries
Do Not Mix Alkaline, Standard, Lithium or Rechargeable Batteries
3. Keep the transmitter 5-10 feet from the Digital Atomic Clock for 15 minutes to establish a good connection.
4. Within 3 minutes the outdoor temperature should be displayed on the Digital Atomic Clock. If the outdoor temperature
is not displayed after 3 minutes remove batteries from the transmitter and the Digital Atomic Clock for 60 seconds and
start again from step 1.
5. For optimum 433 MHz transmission, the outdoor transmitter should be placed within 200 feet (60 meters, open air)
from the Digital Atomic Clock.
Note: The Digital Atomic Clock will start searching for the WWVB time signal for 2-10 minutes at start up.
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 Digital Atomic Wall Clock. However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The Digital Atomic 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 appear on screen if the reception of atomic time is
successful.
The tower icon will show solid when the Digital Atomic Clock has received the WWVB signal.
No tower icon displayed. The Digital Atomic Clock was unable to receive a signal at this time.
Reposition the Digital Atomic Clock for better signal reception or try again at bedtime.
The Digital Atomic Clock will start searching at UTC: 07:00 and if no reception on the first attempt it 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 in ABOUT 2-3 minutes.
If the signal is marginal it will try to receive a signal for up to 10 minutes.
Manual Search: Hold the -/TIME button to start a manual signal search.
Note: In case the Digital Atomic Clock is not able to detect the WWVB signal (disturbances, transmitting distance, etc.);
the time can be manually set using the Program Menu.

INSTALL BATTERIES IN THE DIGITAL ATOMIC CLOCK:
1. Remove battery cover: Slide tab to the down and pull out to remove
battery cover.
2. Install two 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 Digital Atomic Clock does not show indoor temperature after 60
seconds, remove 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. Insert two fresh AA batteries into the transmitter. Observe the correct polarity (see
marking inside battery compartment).
3. Keep transmitter 5-10 ft. from the Digital Atomic Clock during setup.
4. After 15 minutes, if the outdoor temperature shows on the Digital Atomic Clock, you can
move the outdoor transmitter outside to a shaded location within range of the Digital
Atomic Clock.
POSITIONING THE ATOMIC 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 Digital Atomic Clock should be six feet from other electronics or wireless devices
in order to best receive the outdoor temperature transmitter signal.
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 Digital Atomic Clock, below the battery
compartment.
Once the foldout table stand is extended, place the Digital Atomic Clock in an appropriate location.
Wall Mount
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 Digital Atomic Clock onto the screws, using the hanging holes on the backside.
Gently pull the Digital Atomic Clock down to lock the screws into place.
Note: Always ensure that the Digital Atomic Clock locks onto the screws before releasing.
POSITIONING THE WIRELESS OUTDOOR TRANSMITTER:
Once the Digital Atomic Clock displays the outdoor temperature, place the clock and the transmitter in the desired
locations and wait approximately 1-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.

Wall Mount
Choose a shaded location (under an overhang) for the transmitter that is within the confirmed wireless
reception range of the Digital Atomic Clock for accuracy.
Install one mounting screw (not included) into a wall leaving approximately ½ of an inch (12.7mm)
extended.
Place the hanging hole (on the back of the transmitter) onto the mounting screw and gently slide the
transmitter down onto the mounting screw to secure it into place.
IMPORTANT: For true temperature readings, mount the transmitter out of direct sunlight on a North-facing wall or in any
other well shaded area like under an eave or deck rail. 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. Place the
transmitter at least 6 feet in the air to improve signal transmission.
