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.

4.  
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 PMfor 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.  
2.  
Press and release the SET key to enter the “DST  
Setting“.  
DST (daylight saving time)  
1.  
The ON digit will start flashing on LCD1. Set the DST ON  
or OFF by pressing the + key.  
Press and release the SET key to enter the “Language  
Setting“.  
2.  
Note: The DST default is “ON”, meaning that the WWVB will  
automatically change the time according to Daylight Saving  
Time in the spring and fall. For areas that do not recognize  
DST changes (Arizona and parts of Indiana) turn the DST  
“OFF”.  
After following the steps above (Time zone setting, DST  
ON/OFF, Language display setting):

Alarm icon ((())) (ON)  
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-  
controlled clock down to lock the screw  
into place.  
2.  
The alarm will be automatically ON when the alarm time is set.  
To deactivate the alarm (OFF), press and release once the  
ALM key in normal mode display. The alarm icon will  
disappear, the alarm is now off.  
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.
