ABOUT WWVB (Radio Controlled Time)
The NIST (National Institute of Standards and Technology—Time and Frequency
Division) WWVB radio station 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 Moon Phase Clock.
However, due to the nature of the Earth’s Ionosphere, reception is very limited during
daylight hours. The Moon Phase 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 is continually measuring every
second, of every day, to an accuracy of ten billionths of a second per 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 Moon Phase Clock regulates the
WWVB transmitter. For more information about WWVB please see the NIST website at
http://www.boulder.nist.gov/timefreq/stations/wwvb.htm
QUICK SET-UP GUIDE
1) Insert two fresh AA batteries into the moon phase clock.
2) Wait 10 minutes for WWVB reception.
3) If there is no WWVB reception, manually set the time and date (see
instructions in the Program Mode section).
4) Program the settings.
5) Mount the WS-8007U in a suitable location where WWVB signals can be
received.

DETAILED SET-UP GUIDE
I) BATTERY INSTALLATION
Note: To avoid start-up problems make sure that the batteries do not spring free.
A) MOON PHASE CLOCK
1) Remove the battery cover,
located on the backside of the
moon phase clock and directly
below the function buttons.
2) Observe the correct polarity,
and install 2 AA batteries.
3) Replace the battery cover.
Note: After the batteries have been installed a tone will sound, and all the
LCD’s (Liquid Crystal Display) will briefly light up. Then the indoor
temperature, the date as “1/ 1”, the weekday as “MON”, and the Moon
Phase will be displayed. Also, the time will appear as “-:--” for
approximately 1 minute. Then the WWVB search is automatically initiated,
and a tower icon appears and flashes with the time colon (no tower icon
will appear if the WWVB is too weak to be detected). While the WWVB
search is being conducted various numbers will appear in the time display.
The numbers “0”, “1”, or “8” will appear in the hour position and the
seconds will appear in the minute display. The moon phase clock will either
display the WWVB time, or discontinue the search after 10 minutes if the
time is not found. When the search is cancelled “-:--”will appear in the
time LCD. The moon phase clock will conduct a WWVB search every hour
until the first signal is found. Once the WWVB time is found, a search is
automatically conducted nightly at midnight. If the signal is found at
midnight, the tower icon will remain, if not, another search will take place
every hour (up to 6:00 am) until the signal is found successfully. If no signal
is found during this period, the tower icon will not appear and the clock will
search again at 12:00 am the next night.

• wall mounting.
I) FOLDOUT TABLE STANDS
The Foldout table stand legs are located on the backside,
at the lower corners, and on both sides of the battery
cover. The hinges are towards the edges of the moon
phase clock, and the ends (with no hinge) need to be
folded out towards the edge. Once the foldout table
stands are extended, place the moon phase clock in an
appropriate location.
II) WALL MOUNTING
1) Using a straightedge, horizontally space at 3-
15/16 of an inch (100.58mm) three screw
positions on a wall.
2) Install three mounting screws (not included) into
a wall within transmission range—leaving
approximately 3/16 of an inch (5mm) extended
from the wall.
3) Place the moon phase clock onto the screws, using the hanging holes on the
backside. Gently pull the moon phase clock down to lock the screws into
place.
