SETTING UP:
1. First, insertthe batteries into the Weather Station (see “How to install and replace
batteries in the Weather Station”below). Once the batteries are in place, all segments of
the LCD will lightup brieflyand a short signaltone willsound. Following the displayof the
time as 0:00, the seconds, the date as 1.1.04,the moon and stars icons, the weather icons,
air pressure 1013.0 hPa and some weather information, the indoor temperature and
humiditywill be measured. If the indoor temperature and humidityare not displayed after 30
seconds,remove the batteriesand waitfor at least 15 seconds before reinserting them.
Once the indoor data is displayed proceed to step 2.
2. Within 3 minutes of activating the Weather Station,place the batteriesinto the transmitter
(see “How to installand replace batteries in the Outdoor Thermo-hygrotransmitter“
below).
3. After inserting the batteries into the transmitter, the Weather Station will start receiving data
from the transmitter. The outdoor temperature and humidityshould then be displayed on the
Weather Station. Ifthis does not happen after 3 minutes, the batteries will need to be
removed from both units and resetfrom step 1.
4. The Weather Station can receive up to3 remote Thermo-hygro transmitters. If you have
purchased additionaltransmitters, repeat from step 2 for all extra transmitters.However,
ensure that you leave 10 secondsin between the reception of the lasttransmitter and the
set-up of the following transmitter.The Weather Station will number the transmittersin the
order of set-up, i.e. the first transmitter will have the temperature and humiditydisplayed
with the number 1 against itand so on.
5. With less than 3 transmitters received, the weather station will tryto pickup the remaining
one in approximately3 minutes.If3 transmitters are received, the weather station will stop
further reception.
6. Once the outdoor temperature and humidityreception has been completed and data had
been displayed on the Weather Station,the DCF-77 time code reception isautomatically
started. This takes typicallybetween 3-5 minutes in good conditions.
7. Ifafter 10 minutes, the DCF time has not been received, use the SET keyto manuallyenter
a time initially. The clockwill automaticallyattemptto receive the DCF time from 2:00 to
6:00 am for a successful reception. When DCF signal reception is successful, the received
time will override the manuallysettime.The date is also updated with the received time.
The nextreception attempt will occur on the following day.(Please refer also to noteson
“Radio controlled Time Reception” and “Manual Time Setting”).
HOW TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather Station uses3 xAA, IEC LR6, 1.5V batteries.When batteries need to be replaced,
the lowbatterysymbol will appear on the LCD.

27
To install and replace the batteries, please follow the steps
below:
1. Insert finger or other solid objectin the space at the
bottom center of the batterycompartment and lift up to
remove the cover.
2. Insert batteries observing the correct polarity(see
batterycompartment marking).
3. Replace batterycover.
HOW TO INSTALL AND REPLACE BATTERIES IN THE OUTDOOR THERMO-
HYGRO TRANSMITTER
The outdoor Thermo-hygro transmitter uses 2xAA IEC LR6, 1.5Vbatteries. To
install and replace the batteries, please follow the stepsbelow:
1. Remove the batterycover at the front side with a small screwdriver.
2. Insert the batteries,observing the correct polarity(see battery
compartmentmarking).
3. Replace the batterycover on the unit.
Note:
In the event of changing batteries in anyof the units, all units need to be reset byfollowing the
setting up procedures. This is becausea random securitycode is assigned bythe transmitter at
start-up and thiscode must be received and stored bythe Weather Station in the first 3 minutes
of power being supplied to it.
BATTERY CHANGE:
Itis recommended to replace the batteries in all units on an annual basis to ensure optimum
accuracyofthese units.
Please participate in the preservation of the environment. Return used batteries
to an authorised depot.
DCF-77 RADIO CONTROLLED TIME RECEPTION:
The time base for the radio controlled time is a Cesium Atomic Clockoperatedbythe
Physikalisch Technische BundesanstaltBraunschweigwhich has a time deviation of less than
one second in one million years.The time is coded and transmitted from Mainflingen near
Frankfurtvia frequencysignal DCF-77 (77.5 kHz) and hasa transmitting range of approximately
1,500 km. Your radio-controlled Weather Station receives this signal and converts it to showthe
precise time in summer or wintertime.
The qualityof the reception depends greatlyon the geographic location. In normal cases, there
should be no reception problems within a 1,500km radius around Frankfurt.
After the temperature and humidityreception is completed in initialsetup, the DCF tower icon in
the clockdisplaywill start flashing in the upper right corner of the firstsection of the LCD. This
indicates that the clockhasdetected the presence of a radio signal and is trying to receive it.
When the time code is received, the DCF tower becomes permanentlylit and the radio-
controlled time will be displayed.
Ifthe tower icon flashes, butdoes notset the time or the DCF tower doesnot appear at all, then
please take note of the following:
•Recommended distance to anyinterfering sourceslike computer monitorsor TV sets isa
minimum of 1.5 - 2 meters.
•Within ferro-concrete rooms (basements, superstructures), the received signal is naturally
weakened. In extreme cases, pleaseplace the unit close toawindow and/or point its front
or backtowards the Frankfurt transmitter.

ALM STOP key
•During nighttime, the atmospheric disturbances are usuallyless severe and reception is
possible in most cases. A single dailyreception is adequate to keep the accuracy
deviation below1 second.
