SETTING UP
Note: This weather station receives only one outdoor transmitter.
1. First, insert the batteries in the transmitter (see “How to install and replace batteries
in the thermo-hygro transmitter” above).
2. Within 30 seconds of powering up the transmitter, insert batteries and AC adapter in
the weather station (see “How to install and replace batteries in the weather
station” above). Once the batteries and AC adapter are in place, all segments of the
LCD will light up briefly and a short signal tone will sound. Then the indoor temperature,
humidity and the time as 0:00 will be displayed. If these informations are not displayed
on the LCD after 60 seconds, remove the batteries and wait for at least 60 seconds
before reinserting them. Once the indoor data is displayed user may proceed to the
next step.
3. After the batteries are inserted, the weather station will start receiving data signal from
the transmitter. The outdoor temperature and humidity data should then be displayed
on the weather station. If this does not happen after 2 minutes, the batteries will need
to be removed from both units and reset from step 1.
4. In order to ensure successful 868 MHz transmission, the distance between the weather
station and the transmitter should be within 100 meters (see notes on “Positioning”
and “868 MHz Reception”).
5. Once the outdoor data reception test period is completed, the DCF tower icon in the
clock display will start flashing in the upper left corner. This indicates that the clock has
detected that there is a radio signal present and is trying to receive it. When the time
code is received, the DCF tower becomes permanently lit and the time will be
displayed.
TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The weather station uses 2 x AA, IEC LR6, 1.5V
batteries AND the AC adapter. 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.
TO INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO
TRANSMITTER
The outdoor 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 battery cover by pushing the battery cover upwards with
your thumb.
2. Insert the batteries, observing the correct polarity (see battery
compartment marking).
3. Replace the battery cover on the unit.
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.
ADD DEVICE TO MOBILE-ALERTS SYSTEM
(MOBILE ALERTS gateway needed, sold separately)
Open the app, dashboard is displayed. Tap "Add new sensor" and scan the QR code on the
back of the MA10920. Then set a name for the sensor. To set a name, select the transmitter
and then tap on the left area of the pencil icon in the upper right.
Note: only the data for indoor, outdoor temperature and indoor, outdoor humidity are
transmitted to Mobile-Alerts.
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time is a Cesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than
one second in one million years. The time is coded and transmitted from Mainflingen near
Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controlled weather station receives this signal and
converts it to show the precise time in summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal cases,
there should be no reception problems within a 1,500 km radius of Frankfurt.
DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at
03:00 am, then the next reception takes place the next hour and so on until 06:00am, or until
the reception is successful. If the reception is not successful at 06:00 am, then the next
attempt will take place the next day at 02:00 am.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all,
then please take note of the following:
Recommended distance to any interfering sources like computer monitors or TV sets is
a minimum of 1.5 - 2 meters.
Within ferro-concrete rooms (basements, superstructures), the received signal is
naturally weakened. In extreme cases, please place the unit close to a window and/ or
point its front or back towards the Frankfurt transmitter.
During nighttime, the atmospheric disturbances are usually less severe and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy
deviation below 1 second.

WEATHER FORECASTING ICONS:
The weather icons in the second section of LCD can be displayed in any of the following
combinations:
For every sudden or significant change in the air pressure, the weather icons will update
accordingly to represent the change in weather. If the icons do not change, then it means
either the air pressure has not changed or the change has been too slow for the weather
station to register. However, if the icon displayed is a sun or raining cloud, there will be no
change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since
the icons are already at their extremes.
The icons displayed forecasts the weather in terms of getting better or worse and not
necessarily sunny or rainy as each icon indicates. For example, if the current weather is
cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is
not raining. It simply means that the air pressure has dropped and the weather is expected to
get worse but not necessarily rainy.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 12-24
hours. This will allow sufficient time for the weather station to collect air pressure data at a
constant altitude and therefore result in a more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather
forecasting feature is estimated to have an accuracy level of about 75% due to the varying
areas the weather station has been designed for use. In areas that experience sudden
changes in weather (for example from sunny to rain), the weather station will be more
accurate compared to use in areas where the weather is stagnant most of the time (for
example mostly sunny).
If the weather station is moved to another location significantly higher or lower than its initial
standing point (for example from the ground floor to the upper floors of a house), discard the
weather forecast for the next 12-24 hours. By doing this, the weather station will not mistake
the new location as being a possible change in air-pressure when really it is due to the slight
change of altitude.
WEATHER TENDENCY INDICATOR
The weather tendency indicators (located on the left side of the weather icons) are working
together with the weather icons. When the indicator points upwards, it means that the air-
