Important Notes
System Start
Insert two LR6 (AA size) batteries into the transmitter. The LED located in the middle on the front of the
transmitter will illuminate for 4 seconds then go off. The transmitter will make an initial data transmission
and then start the radio controlled time reception routine. If the time signal can be detected correctly the
LED will flash 5 times and then remain on for 20s, indicating the time signal has been found correctly (note no
time signal is available in Aus/NZ). When reception of the time signal is not possible the transmitter will
terminate radio controlled time reception after no more than five minutes and resume normal transmission.
During the radio controlled time reception period there is no transmission of the outdoor weather data to the
console.
Insert two LR6 (AA size) batteries into the Base Station. The console will illuminate for a few seconds with all
the display segments illuminated for checking. After this the Base Station will make an initial measurement
and start to register the transmitter (the Outdoor Reception Signal icon will be turned on). Do not touch the
Base Station before the outdoor data is received or the outdoor sensor learning mode will be terminated.
When the outdoor transmitter has been registered the Base Station will automatically switch to the normal
display mode from which all further settings can be adjusted by the user.
If no radio controlled clock (RCC) signal is detected during the initial setup, the transmitter will try once every
hour to get the RCC signal until a signal is received. Once the transmitter receives the RCC signal it will
transmit the signal to the Base Station which will display the Radio Controlled Clock icon and the time will
synchronise to the RCC time. If the Base Station does not receive the RCC signal or loses the signal the RCC
icon will not be displayed.
Positioning
Once you have verified that all of the components of the weather station are working they can be positioned
in their permanent places. Before permanently mounting make sure that all the components work properly
together at their chosen mounting or standing locations. If there appear to be problems with the 433 MHz
radio transmission they can mostly be overcome by moving the mounting locations.
Note: The radio communication between the receiver and transmitter in an open field can reach a distance of
up to 100m providing that there are no interfering obstacles such as buildings, trees, vehicles, high
voltage lines, etc. Radio interferences such as 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.
Reconnecting Lost Signal
If no outdoor weather data is displayed as a result of loss of signal during set up, mounting, changing of
batteries in the transmitter or plugging or unplugging cables, simply press and hold the DOWN key for 4
seconds then release. After this the Base Station will make an initial measurement and start to register the
transmitter (the Outdoor Reception Signal icon will be turned on). Do not touch the Base Station before the
outdoor data is received (this may take several minutes) or the outdoor sensor learning mode will be
terminated. When the outdoor transmitter has been registered the Base Station will automatically switch to
the normal display mode from which all further settings can be adjusted by the user.
Note: When replacing batteries in the transmitter wait two minutes before re-inserting for a proper reset.
Wind Direction
On the edge of the wind direction sensor, there are four letters - “N”, ”E”, ”S” and “W” representing the
directions North, East, South and West. The wind direction sensor has to be adjusted so that the directions on
the sensor are matching your real location. A permanent wind direction error will be introduced when the

WS2083
- 5 -
wind direction sensor is not positioned correctly during installation.
Batteries
Note: Incorrectly inserting the batteries may cause a fault and invalidate the warranty so take care to insert
them with the correct polarity.
Note: Many rechargeable batteries are 1.2V and as such are not suitable for this unit which requires 1.5V
batteries. Rechargeable batteries also often leak their peak charge quickly which can cause reduced
transmission range. As such we recommend avoiding the use of rechargeable batteries.
Note: The performance of Alkaline batteries can be significantly reduced in colder environments resulting in
loss of signal. In this case we recommend the use of Lithium batteries in the thermo-hygro sensor.
Low Battery Indicator
The transmitter low battery indicator may illuminate when temperatures are outside the range of
10-35C. This does not necessarily indicate low batteries and will switch off once the temperature returns to
this range (also see note above on the use of Alkaline batteries).

pressure provided for your area on the Met Service or Bureau of Meteorology websites. If
Absolute pressure is selected, skip this step.
Pressure high alarm (press ON/OFF to enable/disable). If the alarm is enabled, an alarm symbol
appears in the display.
Pressure low alarm (press ON/OFF to enable/disable). If the alarm is enabled, an alarm symbol
appears in the display.
Maximum pressure value (since last reset). Resetting the maximum pressure value - when both
the pressure value and MAX icon are flashing, hold the ENTER key for 3s, the maximum pressure
value will be reset to the current reading.
Minimum pressure value (since last reset). Resetting the minimum pressure value - when both the
pressure value and MIN icon are flashing, hold the ENTER key for 3s, the minimum pressure value
will be reset to the current reading.
Pressure Bar Graph
Press the MENU key six times to select the PRESSURE HISTORY section, the PRESSURE HISTORY section digits
will start flashing. Press the UP or DOWN key to select the bar graph time scale (either 12 hrs or 24 hrs).
Weather Forecast
Press the MENU key seven times to select the TENDENCY section, the TENDENCY section digits will start
flashing. Press the UP or DOWN key to select the tendency (not generally required as this will adjust
automatically over a few days as the unit collects data and begins forecasting).
Press the ENTER key to select the following modes, then press the UP or DOWN key to set the value:
Set the pressure threshold from 2-4hPa (default 2hPa)
Set the storm threshold from 3-9hPa (default 4hPa)
Note: The prediction is for the upcoming 12 - 24 hours and does not necessarily reflect the current weather
situation. It calculates on the basis of the pressure changes that have occurred during the past 24 hours the
most likely weather forecast for the upcoming 12 - 24 hours. The weather forecast predicted has a probability
of 70%. This means that observed over a period of several weeks, 7 from 10 forecasts for the upcoming 12 -
24 hours will be correct. Observing the forecast for only a few days isn't sufficient to draw any conclusions re
accuracy.
Notes on the pressure sensitivity setting for weather forecasting
The pressure threshold can be set to suit the user’s requirements for weather forecasting - anywhere from
2-4hPa (default 2hPa). Areas that experience frequent changes in air pressure require a higher setting
compared to areas where the air pressure is stagnant. For example if 4hPa is selected, then there must be a
fall or rise in air pressure of at least 4hPa before the weather station will register this as a change in weather.
Notes on the storm threshold setting
The storm threshold can be set to suit the user’s requirements for storm forecasting - anywhere from 3-9hPa

WS2083
- 12 -
(default 4hPa). When there is a fall below the pressure threshold within any given 3 hour period, the storm
forecasting will be activated and the clouds with rain icon as well as the tendency arrows will flash for 3 hours
indicating the storm warning feature has been activated.

Trouble Shooting
Problem
Solution
I am not receiving any outside data.
Check that batteries in both units are fresh and fully charged.
Alkaline batteries slow down and freeze in colder temperatures
which leads to signal dropouts so we recommend Lithium batteries
in colder climates. Also avoid rechargeable batteries as many are
1.2V (standard 1.5V required) and they also leak their peak charge
quickly even if they are 1.5V.
Put the batteries in the receiver last to force a proper resync.
Check that the transmitter is not out of range. Test this by taking
the receiver closer to the transmitter, remove and reinsert the
batteries and wait for a few minutes to see whether the signal is
picked up.
Check for sources of interference (cordless phones, baby monitors,
PC monitors etc). If this is an issue the console and/or transmitter
will need to be relocated.
If none of these is causing the problem you may have a faulty
transmitter.
My wind speed appears to be under
reporting.
When set to Average, wind speed is measured as the average speed
recorded over the 48 second period between transmissions. In
gusty weather this can appear as though it is under reading. Set
this to Gust (see Wind section above) to view the maximum wind
speed during each 48 second period.
My rain gauge is under reporting
rainfall or not recording it at all.
Remove the cover from the rain gauge and check for spider webs etc
that may be impeding the tipper’s motion. Tip the tipper back and
forth, each tip should register as 0.3mm on the console if it is
operating correctly (remember the transmission interval is every 48
seconds so allow sufficient time for the console to register the tips).
My rain gauge is over reporting
rainfall.
On rare occasions wind can enter the rain gauge from underneath
and cause the rain gauge’s tipper mechanism to tip and register false
rain readings. In this case mount the rain gauge on a flat surface or
mount a plastic plate under the rain gauge to prevent the wind
entering. Insecurely mounted sensor trees can also sway in strong
winds and cause false rain readings.
