Next the WWVB time code reception will automatically
start. This reception typically takes 10 minutes in good
conditions. If after 10 minutes the WWVB time has not
been received, use the “SET” key to enter the set-up
mode to manually set the Time, Time Zone and Date
(see manual settings below). The clock will continue to
search for WWVB each hour between 12am and 6am.
When the clock has successfully connected with WWVB,
it will override the manually set time and date.

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

Insert 1 x AA Alkaline battery into the compartment,
observing the correct polarity (see marking inside battery
compartment.
Replace battery cover
DO NOT SET THE CLOCK.
Note: For best performance, batteries should be replaced at
least once every 2 years to maintain the best running accuracy.
Ensure that the batteries used are new and the correct size.
Please help in the preservation of the
environment and return used batteries to an
authorized depot.
SETUP AFTER CHANGING/REPLACING THE
BATTERY
After 15 minutes the WWVB tower icon in the clock display will
start flashing in the top center of the LCD. This indicates the
clock has detected a radio signal and is trying to receive it.
When the time code is received, the WWVB tower becomes
permanently lit and the time will be displayed.
1.
After powering up the solar clock, all LCD segments will
light up briefly and it will show the time (12:00), indoor
temperature, date, and indoor humidity.

If the tower icon flashes, but does not set the time or the
WWVB tower does not appear at all, then please take note of
the following:
briefly before displaying the information for time, date, indoor
temperature and indoor humidity.

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: the time will be displayed with an additional “PM” for the
time from 12:00 noon until 11:59.
TIME ZONE
The time zone can be set between the +/–12 hour range in
LCD2. To do this:
Note: The unit will still try to receive the signal every day
despite it being manually set. When it does receive the signal, it
will change the manually set time into the received time. During
reception attempts the WWVB tower icon will flash. If reception
has been unsuccessful, then the WWVB tower icon will not
appear but reception will still be attempted the following hour.
1.
The time zone (LCD2) will start flashing (Default setting
"EST -5“). Select the desired time zone by pressing and
releasing the + key.
Time zone settings: -12, -11, -10, ALA, PST, MST, CST,
EST, ATL, -3, -2, -1, 0, +1, +2...+12. (Default: EST)
WWVB time reception takes place from 12:00 am through 6:00
am each day (attempts WWVB reception every full hour within
this time frame). When the time signal is received for example
at 1:00 am, the radio-controlled clock will not attempt to receive
the WWVB signal for the remaining hours until 6:00 am.
Therefore, the next signal attempt will take place between
12:00 am and 6:00 am the next day. The other times WWVB
reception takes place, are upon setup and after manual time set
exiting mode. Reception is generally not possible during
daylight hours due to the interference of the sun.

WALL MOUNTING
1.
Install a mounting screw (not included)
into a wall—leaving approximately 3/16
of an inch (5mm) extended from the wall.
Place the radio-controlled solar clock
onto the screw, using the hanging hole
on the backside. Gently pull the radio-

SNOOZE SETTING
Note: Always ensure that the radio-controlled clock locks onto
the screw before releasing.
The snooze can only be activated during alarm time for a
snooze duration of 10 minutes by pressing the SNZ key on the
back of the clock.
TROUBLESHOOTING:
Problem:
Solution:
The LCD is OFF.
1) Move the solar clock to a brighter
environment.
POSITIONING THE RADIO-CONTROLLED SOLAR
CLOCK:
Before permanently mounting, ensure that the radio-controlled
solar clock is able to receive WWVB signals from the desired
location. Also, extreme and sudden changes in temperature will
decrease the accuracy of the solar clock, and changes in
elevation will result with inaccurate temperatures readings for
the next 12 to 24 hours. These changes will require a 12 to 24
hour wait before obtaining reliable data.
2) Check that the solar panel is not
covered.
3) Replace the battery if using Alkaline
battery.
No reception of WWVB signal
1) It may help reception to face the front
of the radio-controlled clock in the
general direction of Ft. Collins,
Colorado.
Problem:
Solution:
There are two possible ways to mount the solar clock:
use of the foldable table stands, or
wall mounting
2) Wait overnight for signal.

3) Be sure the radio-controlled clock is at
least 6 feet (2 meters) from any
electrical devices, i.e. TV sets,
computers, or other radio controlled
clocks.
4) Remove batteries for five minutes,
reinsert and leave the unit alone
overnight without pressing any keys.
Hour is incorrect (minute and date are
correct).
Avoid areas where the unit can be exposed to sudden
changes in temperature, i.e. direct sunlight, extreme cold
and wet/moist conditions as these will lead to rapid
changes which reduce the accuracy of readings.
When cleaning the LCD and casing, use a soft damp
cloth only. Do not use solvents or scouring agents.
Do not submerge the unit into water.
Immediately remove all low powered batteries to avoid
leakage and damage. Replace only with new battery of
the recommended size.
