When the weather station is receiving the WWVB time signal, the
outdoor transmitter data signal will temporarily not be received by
the weather station. During this short period of time, the outdoor
readings shown on the weather station will not be renewed until the
WWVB time signal is successfully received.
TO INSTALL AND REPLACE BATTERIES IN THE THERMO-
HYGRO TRANSMITTER
The Thermo-Hygro Transmitter uses 2 x AA, IEC, LR6,
1.5V batteries. To install and replace the batteries,
please follow the steps below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity
(see marking).
3. Replace the battery cover.
Note:
In the event of changing batteries in any of the units, all units need to be
reset by following the setting up procedures. This is due to a random
security code assigned by the transmitter at start-up. This code must be

received and stored by the Weather Station in the first 3 minutes of power
being supplied to the transmitter.
TO INSTALL AND REPLACE BATTERIES IN THE WEATHER
STATION
The Weather Station uses 2 x C, IEC LR14, 1.5V batteries. To install and
replace the batteries, please follow the steps below:
1. Insert finger or other solid object in the space at the bottom center
of the battery compartment and lift up to remove the cover.

2. Insert batteries observing the correct polarity (see marking).
3. Replace compartment cover.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis
to ensure optimum accuracy of these units.
Please participate in the preservation of the
environment. Return used batteries to an authorized
depot.
DEVICE RESET
The Weather Station and the Thermo-hygro transmitter need to be reset
when one of the following conditions occur:
Unsuccessful 915 MHz signal reception.
Malfunction on the units.
Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1
minute before powering up the Weather station again. Proceed from step
1 in “Setting Up”.

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 projection station.
However, due to the nature of the Earth’s Ionosphere, reception is very
limited during daylight hours. The wireless weather station 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
(303)499-7111. 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
