SETTING UP:

When one transmitter is to be used

1. First, insert the batteries into the Thermo-hygro transmitter. (see “How to install and replace batteries in the Thermo-hygro transmitter“).

2. Immediately after and within 2 minutes, insert the batteries into Weather station (see “How to install and replace batteries in the Weather station”). Once the batteries are in place, all
segments of the LCD will light up briefly. Following the time as 0:00 and the "weather man" icon will be displayed. If these are not displayed after 60 seconds, remove the batteries and
wait for at least 10 seconds before reinserting them.

3. After inserting the batteries into the transmitter, the Weather station will start receiving data from the transmitter. The outdoor temperature/ humidity and the signal reception icon should
then be displayed on the Weather station. If this does not happen after 3 minutes, the batteries will need to be removed from both units and reset from step 1.

4. In order to ensure sufficient 868 MHz transmission however, this should under good conditions be a distance no more than 100 meters between the final position of the Temperature
Station and the transmitter (see notes on “Positioning” and “868 MHz Reception”).

When more than one transmitter is to be used

1. User shall remove all the batteries from the temperatuire station and transmitters and wait 60 seconds if setting has been done with one transmitter before.

2. Insert the batteries to the first transmitter.

3. Within 2 minutes of powering up the first transmitter, insert the batteries to the Weather Station. Once the batteries are in place, all segments of the LCD will light up briefly. Following
time as 0:00 and the weather man icon will be displayed. If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them.

4. The outdoor temperature and humidity from the first transmitter (channel 1) should then be displayed on the Temperature station. Also, the signal reception icon will be displayed. If this
does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1.

5. Insert the batteries to the second transmitter as soon as the outdoor temperature and humidity readings from the first transmitter are displayed on the temperature station.

Note: User shall insert the batteries into the second transmitter within 45 seconds of reception of the first transmitter.

6. The outdoor temperature and humidity from the second transmitter and the "channel 2" icon should then be displayed on the weather station. If this does not happen after 2 minute, the
batteries will need to be removed from all the units and reset from step 1.

7. Insert the batteries to the third transmitter as soon as the "channel 2" icon and outdoor data are displayed on the weather station. Then within 2 minutes, the channel 3 outdoor data from
the third transmitter will be displayed and the channel icon will shift back to "1" once the third transmitter is successfully received. If this is not happen, user shall restart the setting up
from step 1.

Note: User shall insert the batteries into the third transmitter within 45 seconds of reception of the second transmitter.

8. In order to ensure sufficient 868 MHz transmission however, this should under good conditions be a distance no more than 100 meters between the final position of the Temperature

Station and the transmitter (see notes on “Positioning” and “868 MHz Reception”).

IMPORTANT:

Transmission problems will arise if the setting for additional sensors is not followed as described above. Should transmission problems occur, it is necessary to remove the batteries from all
units and start again the set-up from step 1.

9. Once the remote data has been received and displayed on the Weather station, the DCF-77 time code reception is automatically started. This takes typically between 3-5 minutes in

good conditions.
If after 10 minutes, the DCF time has not been received, press the SET key to manually enter a time initially.

Daily DCF reception is done at 02:00 and 03:00. If the reception at 03:00 is not successful, then at 04:00 and 05:00 and 06:00 there are other tries, until one is successful. If the reception at
06:00 is still not successful, then the next try takes place at 02:00 next day.

When this is successful, the received time will override the manually set time. The date is also updated with the received time. (Please refer also to notes on “DCF-77 Radio controlled Time”
and “Manual Time Setting”).

HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The Weather station uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Remove the cover at the back of the weather station.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

HOW TO INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO TRANSMITTER

The Thermo-hygro Transmitter uses 1 x 3.0V IEC CR2032, Lithium battery. To install and replace the batteries, please follow the steps below:

1. Pull out the battery holder at the bottom of the transmitter.

2. Insert the batteries, observing the correct polarity (see marking).

3. Replace the battery holder 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 because a random security code is assigned by
the transmitter at start-up and this code must be received and stored by the Weather station in the first 3 minutes of power being supplied to it

DCF-77 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 around Frankfurt.

Once the outdoor temperature is displayed on the Weather station after initial set-up, 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.
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 metres.

• 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.
