We recommend using alkaline batteries for the remote sensor and
main unit when temperatures are above 32°F (0°C). We recommend
using lithium batteries for the remote sensor when temperatures are
below 32°F (0°C).
•
Avoid using rechargeable batteries. (Rechargeable batteries cannot
maintain correct power requirements).
•
•
ALWAYS install batteries in the remote sensor before the main unit.
Insert batteries before first use, matching the polarity in the battery
compartment
•
Press RESET after each battery change with a paper clip or similar
tool.
•
•
•
Remove protective plastic screen from LCD display (if any).
During an initial setup, place the main unit close to the remote sensor.
After reception is established (the remote temperature will appear on
the main unit’s display), position the remote sensor and the main unit
7
within the effective transmission range of 100 feet (30 meters).
The remote sensor can be placed indoors or outdoors, depending
on the area where the temperature is intended to be measured. If
you intend measuring outdoor elements, place remote sensor outdoors
The main unit must be placed indoors.
•
•
NOTE:
1. Avoid pressing any buttons on the main unit before the remote readings
are displayed.
2. The effective operating range may be influenced by the surrounding building
materials and how the receiver and transmitter are positioned.
3. Place the remote sensor so that it faces the main unit (receiver), minimizing
obstructions such as doors, walls, and furniture.
4. Though the remote sensors are weather-resistant, they should be placed
away from direct sunlight, rain or snow. The best suggested location for the
remote sensor for outdoors is under the eave on the north side of the building.
NOTE: When the temperature falls below freezing, the batteries in the
outdoor remote sensor may have reduced voltage supply and a shorter
effective range. We recommend using lithium batteries at temperatures of
32°F (0°C) and below.

GETTING STARTED
WEATHER DISPLAY
After batteries are installed; remote sensor will transmit temperature data at 45
second intervals. The main unit may take up to two minutes to receive the initial
readings. Upon successful reception, remote temperature will appear next to
the OUT abbreviation on the main unit’s display (The main unit will
automatically update readings at 45-second intervals)
After communication between the main unit and remote sensor has been
established, secure the remote sensor in the desired location.
If no signal is received from the remote sensor within two minutes, dashes [- - -]
will be displayed. Press and hold the DOWN () button on the main unit for
9
two seconds to initiate another signal search.
PLACEMENT OF THE UNITS
The main unit can be placed on the wall or any flat surface indoors. The
remote sensor can be placed indoors or outdoors, on a flat surface or mounted
on the wall.
REMOTE AND INDOOR TEMPERATURE
The remote temperature information line is located next to the indoor
temperature line of the main unit’s display.
The wave icon is located above the OUT abbreviation indicates the reception
status from the remote sensor.
There are three following types of the reception status may be displayed:
The unit is in a searching
mode.
Temperature reading is
securely registered.
No signals detected.
- - -
NOTE: If the indoor or remote temperature goes above or below operating
range stated in specifications, the main unit’s display (weather) will show
dashes “- - -” on the corresponding line.
WEATHER FORECAST
This unit is capable of detecting the atmospheric pressure changes. Based on
collected weather data, it forecasts the weather for the next 12 to 24 hours.
10
NOTE: The weather forecast accuracy is approximately 70%.
The main unit display shows forecasted (predicted) not current
conditions. The SUNNY icon indicates clear weather, even when
displayed during the night-time.
LOST COMMUNICATION
If the main unit display line for the remote sensor reading goes blank, press
and hold DOWN (▼) button for 2 seconds to begin a new signal search. If the
signal still isn’t received, please make sure that:
•
•
The remote sensor is in its proper location.
The distance between main unit and remote sensor is not over 100
feet (30 meters)
•
•
The path between units is clear of obstacles. Shorten the distance if
necessary.
Fresh batteries are installed correctly in both remote sensor and main
unit.
If there is no reception, please perform the following steps:
•
•
Bring the main unit and remote sensor close together.
Remove four (4) small screws from the back of the remote sensor with
small Phillips screwdriver, and open the battery compartment.

•
•
Remove the batteries from the battery compartment and reinstall them
in the same manner. Remote sensor LED indicator will flash showing
transmission of the signal.
Remove the batteries from the main unit and reinstall them in the same
manner.
TRANSMISSION COLLISION
Signals from the other household devices such as wireless doorbells, home
security systems, and entry control, may interfere with this product or cause
temporary reception interruption. This is normal and will not affect the general
performance of the product. The transmission and reception of the temperature
readings will resume once the interference subsides.
WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology) radio station
(WWVB) is located in Ft. Collins, Colorado. It transmits an exact time signal
continuously throughout the most of the continental United States at 60 KHz
frequency. The Atomic Wall Clock can receive this WWVB signal through the
internal antenna from up to 2,000 miles away. Due to the nature of the Earth’s
ionosphere, reception can be limited during the daylight hours. The radio
controlled clock will search for an alternate station that receives the atomic time
signal from the NIST Atomic clock in Boulder, Colorado.
The WWVB tower icon on the unit’s display will flash indicating a radio signal
reception from the WWVB station. If the tower icon is not fully lit, or if the time
and date are not set automatically, please consider the following:
•
During night-time hours, atmospheric disturbances are typically less
severe and radio signal reception may improve. A single daily reception
12
is sufficient enough to keep the clock accuracy within 1 second.
Make sure the unit is positioned at 8 feet (2 meters) distance from any
interference source such as a TV, computer monitor, microwave, etc.
Within concrete wall rooms such as basements or office buildings, the
received signal may be weakened. Always place the Atomic Wall Clock
near the window for better reception.
•
•
ATOMIC CLOCK
Immediately after establishing communication between the main unit and
remote sensor, the atomic time signal receiver will open and start to search for
the atomic time signal. The search usually takes between 5-8 minutes.
NOTE: Do not press any buttons on the main unit during auto search as it
may interrupt product’s operation, and you will need to start set up
procedure again.
Once the atomic time signal is received, the date and time will be set
automatically, and the [ ] icon will appear.
NOTE: It is necessary to set your Time Zone, having in mind that the
default zone is a US Pacific Standard Time (PST). (Refer to MANUAL
SETTINGS section)
If the time signal has not been received in 8 minutes, you may use the MODE
button to set the time and date manually. (Refer to the MANUAL SETTINGS
section).
After the clock is set manually, place the Atomic Wall Clock by the window for
the better reception. The atomic clock receiver is programmed that it will
continue to search for the atomic time signal daily for every hour between 1:00
am and 4:30 am.
Once the time signal has been successfully received, the time and date will be
updated automatically.
