i. Abo t this Man al
Thank You
and Congratulations on selecting a La Crosse
Technology Professional Weather tation! We are positive you will
enjoy the benefits of accurate weather readings and the precise, radio-
controlled time information that our instruments offer. La Crosse
Technology introduced radio-controlled instruments to the U market
in 1991 and continues to be on the cutting-edge of this technology in
America.
This manual will guide you step-by-step through setting up your La
Crosse Technology device. Use this manual to become familiar with
your professional weather station, and save it for future reference.
ii. Glossary of Common Terms
NIST*
The National Institute of tandards and Technology maintains the
primary frequency standard for the United tates. The NI T also
coordinates the United tates time and frequency standards with other
world standards. The NI T provides time and frequency services for
United tates clientele.
WWVB*
The WWVB is an AM radio station in Ft. Collins, Colorado, managed
by the NI T. The WWVB’s function is to broadcast time-of-day
information derived from the NI T atomic clock, located in Boulder,
Colorado.
ATOMIC CLOCK*
An atomic clock is an extremely accurate time device measuring time
by the movements of electrons in cesium atoms. The NI T atomic
clock is one of the most precise clocks in the world, accurate to 10
billionths of one second. The NI T’s atomic clock contributes to the
international group of clocks calculating the Coordinated Universal
Time (UTC)—the official world time.

4
RADIO-CONTROLLED TIME*
A radio-controlled time device is often confused with an atomic clock.
However, a radio-controlled time device receives its time information
from the atomic clock each day through an internal antenna. The
radio- controlled time device searches for an exact time signal every
night when the signal from the WWVB is the strongest. The signal can
be received up to 2,000 miles away through a radio-controlled time
device.
LCD
“LCD” is an acronym for ”Liquid Crystal Display”. This is a common
type of display screen used in televisions, computers, watches, and
digital clocks.
BAROMETER & BAROMETRIC PRESSURE
A barometer is a device that measures the pressure of the air pushing
on it—this measurement is called the barometric pressure. We don’t
actually feel the barometric pressure because the air pressure is
pushing equally in every direction.
RELATIVE AIR PRESSURE
Relative air pressure is the same as the barometric pressure. The
calculation of relative air pressure is a combination of the absolute air
pressure and the altitude.
ABSOLUTE AIR PRESSURE
Absolute air pressure is the actual air pressure on the barometer
without regard to altitude.
INCHES OF MERCURY (inHg)
Inches of Mercury is the common unit of measurement for air pressure
in the United tates.
HECTOPASCALS (hPa)
Hectopascals are the common units of measurement for air pressure
in the International ystem ( I) of measurement. The hectopascal
holds the same value

1 General
Important Note:
Before inserting batteries, please caref lly read the
operation man al.
The Touch creen Weather tation W -3512 includes a Base tation
(Receiver), a Transmitter unit, one Wind ensor, Connecting Cables,
an AC/DC Adapter, and a PC oftware Package on CD-ROM.
The Base tation is equipped with a Touch creen LCD Monitor and
allows the display of a large variety of time and weather data.
From top to bottom:
• Radio-Controlled Time (Time)
• Calendar (Date)
• Weather Forecast (Tendency)
• Air Pressure and Air Pressure History (Pressure, Pressure
History)
• Wind measurement
Also, the information text display (located at the bottom of the LCD),
will show a variety of additional data.
Note:
On the information text display, the min/max of today’s air pressure,
max wind speed, wind gust will be shown time by time. If the set-up
menu is selected, the information in the text display will be temporarily
replaced by the menu operating features.
An added feat re of the Weather Station is the reado t of all
meas red and displayed time and weather data on a PC as well

as the ability to pload the data to Internet Web Sites.
2 Important Operating Notes
• All actions and functions of the Weather tation are started on the
Touch creen by slightly touching (not pressing!) the switching
areas appearing with star (٭) symbols (only in the text section at
the bottom of the LCD) or the displayed values.
• The setting of functions, values, and units is performed by use of
the switching areas ٭ON٭ or ٭OFF٭, ٭UP٭ or ٭DOWN٭ or by
direct unit selection.
• Advancing to any next menu step with ٭NEXT٭, leaving or
terminating all modes with ٭EXIT٭.
• Every time a programming step is activated by touching a
switching area on the Touch creen a tone will sound (with buzzer
switched ON).
• If no areas are pressed for 30 seconds, the LCD will automatically
revert to the normal display mode (automatic time out).

Note: The presence of the "Alarm-On icon" in the section means that
the particular alarm has been enabled.
3 Getting Started
First you must decide whether to use batteries or the AC/DC adapter
to operate the system. Both methods allow the connection of
Transmitter unit and Base tation by cable or by 433 MHz radio signal.
Note: When setting up the Weather tation it is important to tentatively
perform in close proximity (e.g. on a table) a complete wiring
and set-up of the system. This allows you to make sure all

components work properly before positioning them in their final
locations.
3.1 Wiring the System
Independent of the final operating mode at first, the fixed cable of the
Wind ensor has to be connected to the Transmitter unit by plugging it
into the marked receptacle.

The direct cable connection of Transmitter unit and Base tation can
be used if:
• the flexibility of 433 MHz radio transmission is not needed and
• data transmission absolutely free of any environmental
interferences is wanted.
3.2 Power S pply
The Weather tation can be powered by the use of batteries, by the
AC/DC adapter or, by direct cable connection.
3.2.1 Batteries:
• First insert (2) "C" batteries into the battery compartment of the
Transmitter unit.
• Immediately following this insert (3) AA 1.5V batteries into the
battery compartment of the Touch creen Weather tation.
Please help in the preservation of the environment and
ret rn sed batteries to an a thorized depot.
3.2.2 The AC/DC Adapter:
• First insert (2) "C" batteries into the battery compartment of the
Transmitter unit.
• Immediately following this, connect the AC/DC adapter to the
Base tation and then plug it into a regular outlet.

10
Note: In both cases it is important to power the units in this order
because the transmitter will send an identification code which
has to be received and stored by the Base tation within the
first few minutes of operation.
After doing this, full operation of the entire Weather tation ystem is
ensured.
3.2.3 Cable Connection:
An additional feature of the direct cable connection (mentioned in Item
3.1 above) is when using the AC/DC adapter, power is provided to
both the Base tation and the Transmitter unit by only the AC/DC
adapter.
Note: ystem operation with cable connection while at the same time
providing power to the Base tation solely by batteries is not
recommended due to the considerably higher power
consumption. The batteries may however remain in the unit for
emergency supply in case of a power failure.
A change from cable operation to 433 MHz radio transmission
or vice versa is possible because the Weather tation will
recognize this change and will automatically switch to the
appropriate operating mode.
