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

QUICK SET-UP GUIDE
Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.
1. Have the temperature clock and remote temperature sensor 3 to 5 apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote temperature sensor first then into the
temperature clock.
(All remote temperature sensors must be started before the temperature
clock)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the temperature clock and remote temperature sensor will start to talk to each
other and the temperature clock will show both the indoor temperature and an outdoor
temperature. If the temperature clock does not display both temperatures after the 10
minutes please retry the set up as stated above. After both indoor and outdoor
temperatures are displayed for 10 minutes you can place your remote temperature sensor
outdoors and set your time.
The remote temperature sensor should be placed in a dry, shaded area. The remote
temperature sensor has a range of 80 feet. Any walls that the signal will have to pass
through will reduce distance. An outdoor wall or window will have 20 to 30 feet of
resistance and an interior wall will have 10 to 20 feet of resistance. Your distance plus
resistance should not exceed 80 ft. in a straight line.
NOTE: Fog and mist will not harm your remote temperature sensor but direct rain must
be avoided.
To complete the set up of your temperature clock after the 10 minutes have passed please
follow the steps below.

DETAILED SET-UP GUIDE
I) BATTERY INSTALLATION
Note: To avoid start-up problems make sure that the batteries do not spring free.
A) REMOTE TEMPERATURE SENSOR
1) Remove the battery cover. Place your thumb over
the two air-vent slots on the face of the remote
temperature sensor, push down gently, and slide
battery cover down and off.
2) 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).
3) Replace the battery cover.
B) TEMPERATURE ALARM
1) Remove the battery cover,
located on the backside of the
unit 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. The indoor
temperature, the date as “1/ 1”, the
weekday as “MON”, and the remote
temperature will be displayed (within
three minutes). Also, the time will
appear as “-:--” for approximately 1
minute. 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, and the time display will remain on “-:--”). While the WWVB search is
being conducted various numbers will appear in the time display. After 10minutes,
the temperature alarm will either display the WWVB time, or discontinue the search
if the time is not found. If the search is cancelled “-:--” will appear in the time LCD.
The temperature 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.

“-5EST” flashes in the date LCD. The program mode is laid out in a manner that
allows you to program each function separately, or you can follow the instructions
entirely to program the temperature alarm. Complete programming is usually done
for the initial set-up, and will require you to skip step 1 of programming sections III
through VIII. Press the “SNOOZE” button at any time to exit the program mode, or
wait approximately 15 seconds for the temperature alarm to automatically return to
normal operation.

C) INDOOR TEMPERATURE
The indoor temperature appears on the right side of the date LCD. The
temperature is checked every 10 seconds and updated whenever there is a
change.
D) REMOTE TEMPERATURE
The remote temperature will be shown on the right side of the lower LCD
screen. The temperature alarm receives the outdoor temperature (°F or °C) from
the remote temperature sensor, and the temperature appears in the outdoor LCD.
The remote temperature sensor transmits a new temperature to the temperature
alarm 3 times every 10 minutes.
IV) MOUNTING THE REMOTE TEMPERATURE TRANSMITTER
A) The remote temperature sensor can be mounted in two ways:
1) With the use of screws.
2) Using the adhesive tape.
B) MOUNTING WITH SCREWS
1) Remove the mounting bracket from the remote temperature sensor. The
bracket should snap off easily.
2) Place the mounting bracket over the desired location. Through the three
screw holes of the bracket, mark the mounting surface with a pencil.
3) Where marked, start the screw holes into the mounting surface.
4) Screw the mounting bracket onto the mounting surface. Ensure that the
screws are flush with the bracket.
5) Snap the remote temperature sensor onto the mounted bracket.
C) MOUNTING WITH ADHESIVE TAPE
1) With a nonabrasive solution, clean and dry the back of the mounting bracket
and the mounting surface to ensure a secure hold. The mounting surface
should be smooth and flat.
2) Remove the protective strip from one side of the tape.
3) Adhere the tape to the designated area on the back of the mounting bracket.
4) Remove the protective strip from the other side of the tape.
5) Position the remote temperature sensor in the desired location, ensuring that
the temperature alarm can receive the signal.

V) MAINTENANCE & CARE
•Extreme temperatures, vibrations, and shock should be avoided to prevent
damage to the units.
•Clean displays and units with a soft, damp cloth. Do not use solvents or
scouring agents—they may mark and damage the displays and casings.
•Do not submerge in water.
•Immediately remove all low powered batteries to avoid leakage and damage.
Replace with new batteries only, and of recommended size.
•Opening the casings invalidates the warranty. Do not try to repair the units.

TROUBLESHOOTING
Problem: The LCD is faint.
Solution: 1) Replace the batteries.
Problem: “OFL” appears in the indoor temperature LCD.
Solution: 1) Move unit to an area with warmer or cooler surrounding
temperature. Current surrounding temperatures are outside
measuring range.
Problem: No reception of WWVB signal.
Solution: 1) It may help reception to face the front of the temperature
alarm in the general direction of Ft. Collins, Colorado.
2) Wait overnight for signal.
3) Be sure the temperature alarm is at least 6 feet 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 buttons.
5) If problems persist contact La Crosse Technology.
Problem: Hour is incorrect (minute and date are correct).
Solution: 1) Be sure correct time zone and daylight saving time are
selected.
Problem: “--.-” appears in outdoor temperature LCD
Solution: 1) Check batteries in remote
2) If batteries are replaced in remote, the unit must be re-started.
Remove all batteries, and then follow start up procedure.
Problem: “OFL” appears in the outdoor temperature LCD
Solution: 1) Remote temperature is out of range.
2) Check batteries.
3) Interference from an outside source (cordless telephone, etc.)
4) Contact La Crosse Technology.
