The Outdoor Temperature Transmitter
•Remote transmission of outdoor temperature to Weather
Station by 868 MHz
•Shower proof casing
•Wall mounting case (Mounting at a sheltered place. Avoid
direct rain and sunshine)
SETTING UP:
When one transmitter is used
1. First, insert the batteries into the Temperature transmitter. (see “Install and replace
batteries in the Temperature transmitter“).
2. Immediately after and within 25 seconds, insert the batteries into Weather station
(see “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 girl" 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, the Weather station will start receiving data from the
transmitter. The outdoor temperature 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
Weather Station and the transmitter (see notes on “Positioning” and “868 MHz
Reception”).
5. Once the remote temperature has been received and displayed on the Weather
station, the DCF time (radio controlled 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.
When more than one transmitter is used
1. User shall remove all the batteries from the weather station and transmitters and wait
for 60 seconds if setting has been done with one transmitter before.
2. Insert the batteries to the first transmitter.
3. Within 25 seconds 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 girl 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 from the first transmitter (channel 1) should then be
displayed on the Weather 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
readings from the first transmitter are displayed on the Weather station.
Note: User shall insert the batteries into the second transmitter within 10 seconds of
reception of the first transmitter.
6. The outdoor data 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 10 seconds of reception of
the second transmitter.
•And user may require to check the displayed readings on the weather station against

55
those shown on the transmitters in order to recognise the Channel No. of each
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
Weather 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 temperature has been received and displayed on the Weather
station, the DCF time (radio controlled 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.
Note:
Daily DCF reception is done at 02:00 and 03:00 every day. 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.
If reception 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”)

INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER
The Temperature Transmitter uses 2 x AA, IEC LR6, 1.5V battery. To
install and replace the batteries, please follow the steps below:
1. Remove the battery compartment cover at the back of the
transmitter.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery compartment 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 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.
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum accuracy
of these units (Battery life See Specifications below).
