INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE STATION

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

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

2. Insert batteries observing the correct polari ty (see marking).

3. Replace compartment cover.

Battery replacement

•

Replace the batteries when the battery symbol of the temperature station appears near t he
indoor temperature display.

•

When the batteries of the transmitter are used up, the low battery icon appears near the
outdoor temperature 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 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 fi rst 3
minutes of power being supplied to it.

SETTING UP:

1.

First, insert the batteries into the transmitter (see “Install and replace batteries in the
temperature transmitter” below).

2.

Within 30 seconds of powering up the transmitter, insert the batteries to the temperature
station (see “Install and replace batteries in the temperature station” below). Once the
batteries are in place, all segments of the LCD will light up briefly. Then the indoor
temperature and the time as 0:00 will be displ ayed. If they are not shown on LCD after 60
seconds, remove the batteries and wait for at least 60 seconds before reinserting them.
Once the indoor data is displayed, user may proceed to the next step.

3.

After the batteries are inserted, the temperature station will start receiving data signal from
the transmitter.

4.

In order to ensure sufficient 868 MHz transmission, the position between the temperature
station and the transmitter should not be more than 100 meters (see notes on “Positioning”
and “868 MHz Reception”).

5.

Once the remote temperature has been recei ved and displayed on the temperature stati on,
the DCF time code reception is automatically started. This takes typically between 3-5
minutes in good conditions.

DCF-77 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 less than one seco nd 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-
