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 weather
station. However, due to the nature of the Earth’s Ionosphere, reception is very
limited during daylight hours. The weather station 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 indoor weather station and remote thermo/hygro sensor 3 to 5
apart.
2. Batteries should be out of both units for 10 minutes.
3. Place the batteries into the remote thermo/hygro sensor first then into
the indoor weather station.
(All remote thermo/hygro sensors must be started before the indoor
weather station)
4. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.
In this time the indoor weather station and remote thermo/hygro sensor will start to
talk to each other and the indoor weather station will show both the indoor
temperature and humidity and the outdoor temperature and humidity. If the indoor
weather station does not display all values after the 10 minutes please retry the set up
as stated above. After all values are displayed for 10 minutes you can place your
remote thermo/hygro sensor outdoors and set your time.
The remote thermo/hygro sensor should be placed in a dry, shaded area. The remote
thermo/hygro 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 thermo/hygro sensor but direct rain
must be avoided.
To complete the set up of your indoor weather station after the 10 minutes
have passed please follow the steps in the Detailed Set Up Guide
.
Note: The Thermo Hygro Transmitter transmits a signal every 3 minutes;
after the batteries have been installed, the Weather Station will search for
the signal for a duration of 5 minutes. If there is no temperature reading in
the OUTDOOR LCD after 5 minutes, make sure the units are within range
of each other, or repeat the battery installation procedure.

DETAILED SET-UP GUIDE
BATTERY INSTALLATION
A. Remote Thermo/hygro Sensor
1. Pull the cylindrical rain cover off the remote
thermo/hygro sensor.
2. Remove the battery cover (located on the backside
of the remote thermo/hygro sensor, above the
mounting post and bracket).
3. Press the arrow and slide the battery cover off.
4. Observing the correct polarity install 2 AA
batteries.
5. Replace battery cover, and place rain cover snugly onto the remote
thermo/hygro sensor.
B. Indoor Weather Station
1. Remove the battery cover. To do this, insert a
solid object in the space provided at the lower-
central position of the battery cover, then push
up and pull out on the battery cover.

Cover
2. Observe the correct polarity, and install 2 AA
batteries.
3. Replace the battery cover.
Note: Immediately after the batteries have been installed, each LCD
(Liquid Crystal Display) will flash, and a tone will sound. Within a few
seconds the indoor temperature, indoor relative humidity, and the
weather icons (sun and clouds) will be displayed. If these items are not
displayed remove the batteries for 10 seconds and reinstall. If the
outdoor temperature is not displayed within four minutes, remove the
batteries from both units, wait 10 seconds, and reinstall. The time will
show -:-- and start searching for the signal. If it successfully receives
the time signal (reception is achieved easiest at night), it will display the
correct time (factory setting is Eastern time zone).

PROGRAM MODE
Programming Note: If 30 seconds is allowed to pass, or either the “IN” or
the “OUT” buttons are pressed during programming modes the unit will
confirm/set the last information entered—the display will stop flashing and
return to normal time-date readings. If you don’t leave the program
sequence during the programming of sections “A” through “G”, you can
advance to step 4 of the next program section. If you do leave the program
sequence (or want to program a specific setting) follow each instructional
step to program that setting. The programming sequence is as follows:
• 12 or 24 Hour Time Setting
• Time Zone Setting
• Daylight Saving Time(DST) Setting
• Time Setting
• Day, Date and Year Setting
•
° F or ° C Setting
• LCD Contrast Setting
FUNCTION KEYS
The Secondary Buttons are located directly below the Primary Buttons, and
behind the La Crosse Technology shield on the face of the unit. To access
the Secondary Buttons: place a solid object in the slot (above the shield)
and gently pull out and down.

A. 12 or 24 Hour Time Setting
1. Press and hold the “SET” button for 3 seconds or until “12h”
or “24h” flashes in the DATE LCD.
2. Press and release the “CH” button to toggle between 12 and
24-hour time.
3. Press and release the “SET” button to confirm the 12/24-hour
time setting and to advance to Time Zone Setting.
B. Time Zone Setting
The default time zone is EST, “-5hr” (Eastern Standard Time), to
change this setting:
1. Press and hold the “SET” button for 3 seconds or until “12h”
or “24h” flashes in the DATE LCD.
2. Press and release the “SET” button 1 time to enter the Time
Zone setting mode.
3. The default Time Zone “-5” will flash in the DATE LCD.
4. Press and release the “CH” button to select your appropriate
time zone. During selection of the Time Zone, the 3 letter
abbreviations for the time zones found in North America will
flash across the top of the TIME LCD. Observe the chart
below showing the corresponding abbreviations, time zones,
and codes.

Note: There are more time zones represented by numbers than
there are represented by 3 letter abbreviations. If you live in
North America you need only be concerned with the ones in the
chart above.
5. Press and release the “SET” button to confirm your selection
and advance to the Daylight Saving Time setting.
C. Daylight Saving Time(DST) Setting
1. Press and hold the “SET” button for 3 seconds or until “12h”

the DATE LCD.
4. Press and release the “CH” button to select “DST 0” or “DST
1.”
“DST 0” indicates that the feature is off and the indoor weather
station will not change times at the daylight saving time changes
automatically. “DST 1” indicates that the feature is on and the
indoor weather station will change times at the daylight saving
time changes automatically.
Note: Some locations (Arizona and parts of Indiana) do not
follow Daylight Saving Time, and should select “DST 0.”
5. Press and release the “SET” button to confirm your selection
and advance to the Time setting mode.

D. Time
There are two methods by which the time can be set:
1. Automatically via WWVB reception, or
2. Manually.
1. WWVB (Remote Control Time)
This method requires you to do nothing, except wait for the signal
to be received and to select a time zone. Reception usually takes
approximately 6-10 minutes during optimal conditions. The best
conditions for reception is at night, between midnight and 6:00
am—when there is less atmospheric interference. To keep your
time as accurate as possible, the indoor weather station conducts a
WWVB search every night between these hours and overrides any
manually set time. The WWVB tower icon (appearing in the TIME
LCD) will flash when a signal-search is in progress, will remain
steady when the signal has been received, and nothing will be
displayed in all other situations. If the WWVB time has not been
received 10 minutes after battery installation you may manually set
the time or wait for WWVB reception. Once the WWVB time
signal is received it will override the manually set time.
2. Manual Time Setting
a. Press and hold the “SET” button for 3 seconds or
until “12h” or “24h” flashes in the DATE LCD.
b. Press and release the “SET” button 3 times.
c. The hour digit will be flashing in the TIME LCD.
d. Press and release the “CH” button to change the
hour – increasing the hours by increments of 1 with
each press of the “CH” button.
e. Press and release the “SET” button to confirm the
hour setting and to advance to the minute setting
mode.
f. The minute digits should be flashing. Press and
release the “CH” button to change the minutes—
