TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The weather station uses 2 x C, IEC LR14, 1.5V batteries. To install and replace the
batteries, please follow the steps below:

The outdoor thermo-hygro transmitter uses 2 x AAA, IEC LR3, 1.5V batteries.
To install and replace the batteries, please foll ow the steps below:

1. Remove the battery cover by pushing the battery cover upwards with
your thumb.

2. Insert the batteries, observing the correct pol arity (see battery
compartment marking).

3.

Replace the battery cover on the unit.

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.

Battery replacement

•

Replace the batteries when the battery symbol of the weather station appears near the
weather icon.

•

When the batteries of the transmitter are used up, the low battery icon appears above
the outdoor humidity display.

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.

SETTING UP

1. First, insert the batteries in the transmitter (see “To install and replace batteries in

2. Within 2 minutes of powering up the transmi tter, insert the batteries in the weather

to be removed from both units and reset from step 1.

weather station and the transmitter should not be more than 100 meters (see notes on
“Positioning” and “868 MHz Reception”).

Note:

In the event of changing batteries of the units, e nsure the batteries do not spring free
from the contacts. Always wait at least 1 minute after removing the batteries before
reinserting, otherwise start up and transmission problems may occur.

5. Once the outdoor data reception test period i s completed, the DCF tower icon in the
clock display will start flashing in the upper l eft corner. This indicates that the clock has
detected that there is a radio signal present and i s trying to receive it. When the time
code is received, the DCF tower becomes permanently lit and the time will be
displayed.

DCF RADIO CONTROLLED TIME

The time base for the radio controlled time i s a Cesium Atomic Clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of l ess
than one second in one million years. The ti me 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-controll ed 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 t he 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.

36

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 i s
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.
