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.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure optimum
accuracy of these units.
Please participate in the preservation of the environment. Return used
batteries to an authorized depot.
SETTING UP
1. First, insert the batteries to the transmitter (see “How to install and replace batteries
in the Temperature transmitter” below).
2. Within 2 minutes of powering up the transmitter, insert the batteries to 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 light up briefly. Then the
indoor temperature and humidity, the time as 0:00 the date as SA.1., the weather icons
(sun and clouds) will be displayed. If the indoor temperature and humidity are not
displayed after 15 seconds, remove the batteries and wait for at least 1 minute before
reinserting them. Once the indoor data is displayed proceed to next step.
3. After the batteries are inserted, the Weather station will start receiving data signal from
the transmitter. The outdoor temperature and humidity should then be displayed on the
weather station. If this does not happen after 2 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 than 100 meters between the final position of the
Weather station and the transmitter (see notes on “Positioning” and “868 MHz
Reception”).
Note: This weather station will receive one outdoor transmitter only.
RESETTING
The Weather Station and the Thermo-hygro transmitter need to be reset when one of the
following conditions occur:
•
Unsuccessful 868MHz signal reception.
•
Malfunction on the units.
•
Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1 minute before powering
up the Weather station again. Proceed from step 1 in “Setting Up”.
DCF 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 deviation of less
than one second 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-controlled 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 1500km radius of Frankfurt.
