ABOUT WWVB
The NIST (National Institute of Standards and Technology—Time
and Frequency Division) 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
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
continually measure 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. For more
information about WWVB please see the NIST website at

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 m i nut es.
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 remote thermo/hygro sensor transmits a signal every 3
minutes; after the batteries have been installed, the indoor 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 o ff.
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.
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
7
is achieved easiest at night), it will display the correct time
(factory setting is Eastern time zone).
PROGRAM MODE
Programming Note: If 20 seconds is allowed to pass during
programming modes, the unit will confirm/set th e last information
entered—the display will stop flashing and return to normal timedate readings
TIME AND DATE
There are two methods by which the time and date can be set:
1) Automatically via WWVB reception (only need to set the
time zone in section III).
This method requires you to do nothing but wait for the signal to
be received, and to select a time zone (default is Eastern Time
Zone). Reception usually takes approximately 6-8 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 time that has been set manually.
The WWVB tower icon (appearing in the TIME LCD) will flash
when a 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 after 10
minutes of battery installation, you may manually set the time or
leave the time function alone (reception will occur regardless).
