3.2.3 Cable Connection:
One further feature of the direct cable connection mentioned in Item
3.1 above is that in case of AC/DC adapter operation power is
provided not only to the Base Station but to the Thermo-Hygro Sensor
as well by just this AC/DC adapter.
Note:
System operation with cable connection while at the same
time providing power to the Base Station solely by batteries is not
recommended due to the considerably higher power consumption. The
batteries may however remain in the unit for emergency supply in case
of a power failure.
A change from cable operation to 433 MHz radio transmission or vice
versa is possible in any case since the Weather Station will recognize
this change and will automatically switch to the appropriate operating
mode.
3.3 System
Start
After inserting the batteries respectively connecting the AC/DC adapter
the LCD of the Weather Station will for a few seconds display all
possible display segments for checking.
Immediately after this the unit will enter the so called play mode during
which for about 15 minutes all measured and received weather data
are being switched through, updated and displayed. During this time
period there will be no reception of the DCF77 time information.
Note:
The play mode phase allows the user of the Weather Station
to check all cables for correct connection and all components for
correct function.
After completing the play mode the Touch Screen Weather Station will
automatically switch to the normal display mode from which all further
settings can be performed by the user. At this point of time the unit will
also automatically start reception of the DCF77 time information.
Important Note:
Reception of the radio-controlled time information will only take
place after completion of the play mode (approx. 15 minutes). In
case the user wants to start the system without waiting for
