The Outdoor Temperature Transmitter

• Remote transmission of outdoor temperature to

temperature Station by 868 MHz

• Weather-resistant casing

• Wall mounting case

• Mount in a sheltered place. Avoid direct rain and sunshine

SETTING UP:

1. First, insert the batteries into the temperature tran smitter. (see “Install and replace
batteries in the temperature transmitter“).

2. Immediately after and within 30 seconds, insert the batteries into Temperature
Station (see “Install and replace batteries in the Temperature 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 and indoor temperature and humidity will be

38

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 Temperature Station will start

receiving data from the transmitter. The outdoor temperature and the signal reception
icon should then be displayed on the Temperature Station. If this does not happen
after 5 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 there should be no more than 330

feet (100 meters) between the final position of the Temperature Station and the
transmitter (see notes on “Mounting” and “868 MHz Reception”).

5. Once the remote temperature has been received and displayed on the Temperature

station, the DCF time (radio controlled time) code reception is automatically started.
This takes typically between 3-5 minutes in good conditions.

Note:

• The Temperature Station will receive one outdoor transmitter only.

• If after 10 minutes, the Atomic time (DCF time) signal 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 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

39

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 Reception” and “Manual Time Setting”)

INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER

The temperature transmitter uses 2 x AA, IEC LR6, 1.5V Alkaline
battery. To install and replace the batteries, please follow the steps
below:

1. Remove the battery compartment cover.

2. Insert the batteries, observing the correct polarity (see 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 because a random security code is assigned by the
transmitter at start-up and this code must be received and stored by the Temperature
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 (Batter y life see Specifications below).
