4) Open the base station’s battery cover located at the back of
the unit and insert 3 x AA, IEC LR6, 1.5V batteries into the bat-
tery compartment and close the battery cover
Setting up using the AC adaptor:
1) Power up all the sensors as described in setting up using bat-
teries above
2) Using the AC adaptor (included), plug it into the mains outlet
and power up the base station by inserting the adaptor jack in-
to the 6.0V DC socket located on the side of the base station
Every time the thermo-hygro sensor is powered up (for example
after a change of batteries), a random security code is transmitted
and this code must be synchronized with the base station to receive
weather data.
When the base station is powered up, a short beep will sound and
all LCD segments will light up for about 5 seconds before it enters
into a 15 minute learning mode to learn the sensors security code.
After the learning mode (or by pressing the MIN/MAX key at any-
time), the base station will start the DCF77 radio controlled time
reception.
Note for DCF77 Radio Controlled Time:
The time and date display is based on the signal provided by a
highly accurate Caesium atomic clock operated by the Physikalisch
Technische Bundesamt in Braunschweig (Germany). This radio-
controlled clock does not only provide for the weather station’s time
and date display but also functions as the time source for all of this
weather station’s memory and history values using time and date
information.
LCD backlight:
When using the power adaptor or under battery operation, the LCD
backlight will switch on for 15 seconds when any key is pressed.
