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 follow the steps below:
1. Remo e the co er at the back of the temperature station.
2. Insert batteries obser ing the correct polarity (see marking).
3. Replace compartment co er.
Batt ry r plac m nt
• Replace the batteries when the battery symbol of the temperature station appears near the
indoor temperature display.
• When the batteries of the transmitter are used up, the low battery icon appears near the
outdoor temperature display.
Not :
In the e ent 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 recei ed and stored by the temperature station in the first 3
minutes of power being supplied to it.

32
SETTING UP:
1.
First, insert the batteries into the transmitter (see “Install and r plac batt ri s in th
t mp ratur transmitt r” below).
2. Within 30 seconds of powering up the transmitter, insert the batteries to the temperature
station (see “Install and r plac batt ri s in th t mp ratur 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 displayed. If they are not shown on LCD after 60
seconds, remo e 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 recei ing 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 R c ption”).
5. Once the remote temperature has been recei ed and displayed on the temperature station,
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 is a Cesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which has a time de iation of less than one second in
one million years. The time is coded and transmitted from Mainflingen near Frankfurt ia frequency
signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your radio-

33
controlled temperature station recei es this signal and con erts 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 1500km radius of Frankfurt.
Once the outdoor temperature is displayed on the temperature station, the DCF tower icon in the
clock display will start flashing in the upper left corner. This indicates that the clock has detected
that there is a radio signal present and is trying to recei e it. When the time code is recei ed, the
DCF tower becomes permanently lit and the time will be displayed.
DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful at
02:00 am, then the next reception takes place the 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.
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 is a
minimum of 1.5 - 2 meters.
• Within ferro-concrete rooms (basements, superstructures), the recei ed 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 se ere and reception is
possible in most cases. A single daily reception is adequate to keep the accuracy de iation
below 1 second.

868 MHz RECEPTION
The temperature station should recei e the temperature data within 3 minutes after set-up. If the
temperature data is not recei ed 3 minutes after setting up (not successfully continuously, the
outdoor display shows “- - -” ), please check the following points:
1. The distance of the temperature station or transmitter should be at least 1.5 to 2 meters
away from any interfering sources such as computer monitors or TV sets.
2. A oid positioning the temperature station onto or in the immediate proximity of metal
window frames.
3. Using other electrical products such as headphones or speakers operating on the same
signal frequency (868MHz) may pre ent correct signal transmission and reception.
5. Neighbors using electrical de ices operating on the 868MHz signal frequency can also
cause interference.

43
Not :
When the 868MHz signal is recei ed correctly, do not re-open the battery co er of either the
transmitter or temperature station, as the batteries may spring free from the contacts and force a
false reset. Should this happen accidentally then reset all units (see S tting up abo e) otherwise
transmission problems may occur.
The transmission range is about 100 m from the transmitter to the temperature station (in open
space). Howe er, this depends on the surrounding en ironment and interference le els. If no
reception is possible despite the obser ation of these factors, all system units ha e to be reset
(see S tting up).
POSITIONING THE TEMPERATURE STATION:
The temperature station is designed to hang onto wall or free standing.
