Battery replacement
•
Replace the batteries when the battery symbol of the weather station
appears above the indoor temperature.
•
When the batteries of the transmitter are used up, the low battery icon
appears above the outdoor temperature displ ay.
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 i s because a security code is
assigned by the transmitter at start-up and this code must be received and
stored by the Weather station in the first 3 minutes of power being supplied to
it.

SETTING UP:
Note: This weather station receives only one outdoor tra nsmitter.
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 of the LCD will
light up briefly. Following the time as 0:00 and the weather icon will be
displayed. If these are not displayed after 60 seconds, remove the
batteries and wait for at least 30 seconds before reinserting them.
3. After inserting the batteries, the Weather stati on will start receiving data
from the transmitter. The outdoor temperature and the signal reception
icon should then be displayed on the Weather stati on. 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 t han 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 recei ved 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.
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time i s a Cesium Atomic Clock operated
by the Physikalisch Technische Bundesanstal t Braunschweig which has a time
deviation of less than one second in one milli on 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 radiocontrolled weather station receives this signal and converts it to show the
precise time in summer or wintertime.
23
The quality of the reception depends greatly on the geographic location. In
MIN/MAX
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 the next hour
and so on until 06:00am, or until the recepti on 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 foll owing:
•
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 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 si ngle daily reception is
adequate to keep the accuracy deviation below 1 second.
