1 General
Important Note:
Before inserting batteries into the units, please
carefully read the operation manual.
The shipping content of the Touch Screen Weather Station WS-3502
includes a Base Station (Receiver), a Relay Transmitter (433 MHz
Transmitter), one Wind Sensor, the respective Connecting Cables, an
AC/DC Mains Adapter and a PC Software Package on CD-ROM.
The Base Station is equipped with a Touch Screen LCD Monitor and
allows the display of a vast variety of time and weather data thanks to
a comprehensive menu (from top to bottom):
•Radio Controlled Time (Time)
•Calendar (Date)
•Weather Forecast (Tendency)
•Air Pressure and Air Pressure History (Pressure, Pressure
History)
•Wind
Furthermore on the information text display (located at the bottom of
the LCD), a number of additional data can be set up.
Note:
On the information text display, The max and min of current air
pressure, wind speed, and the maximum wind gust will be shown from
time to time. In case the set up menu is selected, the information in the
text display will be temporarily replaced by the menu operating steps.
As an important feature, the Weather Station allows by means of
the cable and software included the readout of all measured time
and weather data in the form of complete history data sets, their
processing and graphic presentation on a PC as well as their
publication on Internet Web Sites.

2 Important Touch Screen Operating Notes generally
applicable
•All actions and functions of the Weather Station are activated on
the Touch Screen by slightly touching (not pressing!) the
switching areas appearing in star (٭) symbols (only in the text
section at the bottom of the LCD) or the displayed values.
•In all modes, 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 respective modes with ٭EXIT٭.
•Every programming step activated by touching a switching area
on the Touch Screen is being acknowledged by an acoustic signal
(with buzzer switched ON).
•If during any process previously activated by use of the Touch
Screen no further action is activated for about 30 seconds the
active process is automatically terminated and switched back to
the normal display mode (automatic time out).

3 Putting into Operation
At first it is to decide whether battery supply or mains supply (AC/DC
mains adapter included) will be used to operate the system. Both
methods allow the connection of the Relay Transmitter and Base
Station by cable or by 433 MHz radio signal.
Note: When putting the Weather Station into operation it is important
to carry out in close proximity (e.g. on a table) a complete wiring
and set up of the system in the configuration of its prospective
use. This step will lead to test all components for correct

operation before placing and mounting them at their final
destinations.
3.1 Wiring the System
Independently of the final power supply mode, the fixed cable of the
Wind Sensor has first to be connected to the Relay Transmitter by
plugging it into the marked receptacle.

connection

31
The direct cable connection of Relay Transmitter and Base Station can
be used in the following cases:
•the flexibility of 433 MHz radio transmission is not needed
•data transmission absolutely free of any environmental
interferences is wanted.
3.2 Power Supply
The provision of power to the Weather Station can be performed by
using batteries or by AC/DC mains adapter.
3.2.1 Batteries:
•First insert two Type C 1.5 V batteries into the battery
compartment of the Relay Transmitter.
•Immediately following this insert three Type AA 1.5V batteries into
the battery compartment of the Touch Screen Weather Station.
Please help in the preservation of the environment and
return used batteries to an authorized depot.
3.2.2 AC/DC Mains Adapter:
•First insert two Type C 1.5 V batteries into the battery
compartment of the Relay Transmitter.
•Immediately following this connect the AC/DC mains adapter to
the Base Station and then plug it into a regular mains outlet.

32
Note: In both cases, it is important to respect this order of succession
since the transmitter will send an identification code which has
to be received and stored by the Base Station within the first
few minutes of operation.
After doing this, full operation of the entire Weather Station System is
ensured.
3.2.3 Cable Connection:
One further feature of the direct cable connection mentioned in Item
3.1 above is that in case of AC/DC adapter operation, power is
provided not only to the Base Station but to the Relay Transmitter as
well by just this AC/DC adapter.
Note: System operation with cable connection while at the same time
providing power to the Base Station solely by batteries is not
recommended because of 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 in any case since the Weather Station
will recognize this change and will automatically switch to the
appropriate operating mode.
3.3 System Start
After inserting the batteries respectively connecting the AC/DC adapter
the LCD of the Weather Station will for a few seconds display all LCD
segments for checking.
Immediately after this, the unit will enter the so called play mode
during which for about 15 minutes all measured and received weather
data are being switched through, updated and displayed. During this
time period there will be no reception of the DCF77 time information.
Note: The play mode phase allows the user of the Weather Station to
check all cables for correct connection and all components for
correct operation. The latter will be possible by manually turning
the wind-gauge, moving the weather-vane, etc.

33
After completing the play mode, the Touch Screen Weather Station will
automatically switch to the normal display mode from which all further
settings can be carried out by the user. At this point of time the unit will
also automatically start reception of the DCF77 time information.
Important Note:
Reception of the radio-controlled time information will only take
place after completion of the play mode (approx. 15 minutes). In
case the user wants to start the system without waiting for
completion of the play mode it can be terminated prematurely by
touching the TIME display once in the upper left corner of the
LCD.
Prior to manual setting or reception of radio-controlled time
information there will be no recording of weather history data.
3.4 Placement
After the Weather Station has been checked for correct operation with
regard to the above points and found fit, the mounting of the system
components can take place. It must be ensured however that all
components work properly together at their chosen mounting or
standing locations. If e.g. there appear to be problems with the 433
MHz radio transmission they can mostly be overcome by slightly
moving the mounting locations.
Note: Commonly the radio communication between receiver and
transmitter in the open field reaches distances of max. 100
metres approximately, provided there are no interfering
obstacles such as buildings, trees, vehicles, high voltage lines,
etc.
Radio interferences as they are created by PC screens, radios
or TV sets can in bad cases entirely cut off radio
communication. Please take this into consideration when
choosing standing or mounting locations.
4 Setting Up:
Note: Because of the default settings already determined by the

34
manufacturer, it may not be necessary for the majority of users
to carry out – apart from the Relative Air Pressure (see further
down) - any further basic settings. Changes however can easily
be made if desired.
For basic settings the following menu is started by touching the Touch
Screen in the center of the text display (last two lines on the LCD).
Touching the ٭SETUP٭display will enter the setup mode.
The basic settings can now be performed in the following order:
LCD Contrast →Contrast can be set in 8 steps from 0 to 7 (Default
4).
Time Zone →Time Zones can be set in the range from -12 to +12
hours (Default 0 hours for Central Europe).
DCF77 Radio Controlled Clock (RCC) →ON/OFF. In setting “OFF“
the clock is operating as a normal Quartz clock (Default RCC ON).
