The Outdoor Temperature Transmitter

SETTING UP:

Note:

This weather station receives only one outdoor transmitter.

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

2. Immediately after and within 30 seconds, insert the batteries into Weather station (see “Install
and replace batteries in the Weather station”). Once the batteries are in place, all segments

• Weather-resistant casing

• Wall mounting case

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

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, 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 “Mounting” 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.

Note:

Daily DCF reception is done at full hour between 00:00 to 06:00 every day. If the reception at 00:00 is
not successful, then at 01:00, 02:00, 03:00, 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 00:00 next

The Weather station uses 2 x AA, IEC LR6, 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.

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 (Battery life see Specifications below).

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

(If not successful, the icon will not be shown in LCD) So user can easily see whether the last reception
was successful (icon on) or not (icon off).

For better distinctness the LCD screen is split into 3 sections:

Section 1 - OUTDOOR TEMPERATURE

• Display the outdoor temperature.

• Display the signal reception symbol indicating that receiver is receiving outdoor data

Section 2 - INDOOR TEMPERATURE, INDOOR HUMIDITY, DATE AND WEATHER MAN ICON

• Display the current indoor temperature and humidity in normal display.

• Display the weather condition to be expected in form of 15 fancy weather symbols (featured by

Weather man) which change their appearance depending on the air pressure development and
the current outdoor temperature.

A signal reception symbol is shown indicating that Atomic time(DCF time) signal is
received.

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
