Setting up using the AC adaptor:
1) Power up all the sensors as described in setting up using batteries
above
2) Using the AC adaptor (included), plug it into the mains outlet and
power up the base station by inserting the adaptor jack into 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 anytime), 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 Tech-
nische Bundesamt in Braunschweig (Germany). This radio-controlled
clock does not only provide for the weather station’s time and date dis-
play but also functions as the time source for all of this weather station’s
memory and history values using time and date information.
LED backlight:
When using the power adaptor or under battery operation, the LED
backlight will switch on for 15 seconds when any key is pressed.

Operation using cable connection or wireless 433MHz
Cable Connection:
Using this method of operation will provide interference free transfer of
the weather data from the sensors to the base station. The data send-
ing interval from the sensors to the base station will also be more fre-
quent compared to using 433MHz transmission and will result in higher
power consumption. Therefore batteries will have a shorter life span for
cable connection compared to using 433MHz.
To operate using cable connection, simply use the enclosed 10 meter
cable and connect the thermo-hygro sensor to the base station. Once
