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
Projection alarm. However, due to the nature of the Earth’s Ionosphere,
reception is very limited during daylight hours. The Projection alarm will search
for a signal every night when reception is best.
The WWVB radio station receives the time data 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. For more detail,
visit http://www.boulder.nist.gov/timefreq.htm. To listen to the NIST time, call
[phone]. This number will connect you to an automated time, announced
at the top of the minute in “Coordinated Universal Time”, which is also known as
Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time
changes. After the top of the minute, a tone will sound for every second. It is
possible that your Projection Alarm may not be exactly on the second due to the

variance in the quartz. However, the clock will adjust the quartz timing over the
course of several days to be very accurate; under 0.10 seconds per day.
QUICK SET-UP GUIDE
1) Insert two AA batteries into the remote transmitter.
2) Insert three AA batteries into the projection alarm and/or plug into
wall.
Note: When starting or restarting your projection alarm the remote
transmitter must be started first and then your alarm. After power is
supplied (either battery or AC) ensure that no buttons are pressed for 10
minutes. This will allow time for the projection alarm to communicate
with the remote transmitter as well as receive the WWVB signal.
Note: When using the AC adaptor, plug into the projection alarm first
and then into the electrical outlet (this will help avoid pressing any
buttons inadvertently).
3) Wait 10 minutes for WWVB reception and remote temperature.
4) If there is no WWVB reception, manually set the time and date
(instructions in the Program Mode).
5) Program the settings.
6) Mount the WT-5442 in a suitable location, where WWVB and
transmitter signals can be received.
7) Mount the transmitter where remote temperature measurement is
desired (on the North side of a house for example).
Note: The remote transmitter is weather resistant but not waterproof.
High humidity and mist will not damage the transmitter but direct rain will.
The maximum range between the transmitter and projection alarm is
80ft. open air (no obstructions). Any resistance (i.e. walls, furniture, etc)
between the two will decrease the effective operating range.
8) The projector will activate and remain on if the alarm clock is plugged
in. If only batteries are used, the projector will only be activated when
a button is pressed.
9) See the “Features” section III. for instructions on projection direction,
etc.
DETAILED SET-UP GUIDE

I. BATTERY INSTALLATION
A. REMOTE TEMPERATURE
TRANSMITTER
1. Remove the battery cover.
Observing the correct polarity,
install 2 AA batteries. The

batteries will fit tightly (to avoid start-up problems make sure that
they do not spring free during installation).
5
2. Replace the battery cover.
B. PROJECTION ALARM
1. Remove the battery
cover.
2. Observe the correct
polarity, and install 3 AA
batteries.
3. In addition or instead of
inserting batteries, the
AC adapter can be used. Simply plug the adapter into the receptacle
on the underneath of the alarm clock and then plug the adapter into
the outlet.
4. Replace the battery cover.
5. The projector will activate and remain on if the alarm clock is plugged
in. If only batteries are used, the projector will only be activated when
a button is pressed. The projection is a red light, not harmful under
normal usage, although care should be taken to not look directly into
the light.
Note: After power has been supplied (battery or AC) a tone will
sound, and the LCD (Liquid Crystal Display) will activate. The indoor
temperature and the remote temperature will be displayed (within
three to six minutes). Also, the time will appear as “-:--”. 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, which is typical during daylight hours and
the time display will remain on “-:--”). While the WWVB search is
being conducted various numbers will appear in the time display.
After 10 minutes, the Projection Alarm will either display the WWVB
time, or discontinue the search if the time is not found. If the search
is cancelled “-:--” will remain in the time LCD. The Projection Alarm
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 (until
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.
II. PROGRAM MODE
To enter the Program Mode hold down the “SET” button for 1 second, until
the time zone (“-5” default) flashes in the lower left. The Program Mode

Guide is laid out in a manner that allows you to program each function
separately, or you can follow the instructions entirely to program the
Projection alarm. Complete programming is usually done for the initial
set-up, and will require you to skip step 1 of programming sections “D”
through “H”. Press the “SNOOZE” button at any time to exit the Program
Mode, or wait approximately 15 seconds for the Projection Alarm to
automatically return to normal operation.

C. PROJECTION OF TIME AND/OR REMOTE TEMPERATURE
1. When plugged into an AC outlet, the projection alarm can
continuously project the time and/or remote temperature.
2. When operating on batteries alone, the Projection Alarm will only
project when a button is pressed.
3. The projection will auto-focus for display from three to six feet away.
A dark surrounding will be necessary to clearly see the projection.
4. The default is projecting time (Hour and Minutes). The Projection
Alarm can be set to project the time (M0), remote temperature (M1),
or alternating between time and remote temperature (M2) by
pressing and releasing the “DISPL” button. The selected display
mode will flash on the lower middle as “M0”, “M1” or “M2”.
5. The direction of the display can also be rotated 360°in 90°
