It is also important to allow the Base Station to operate for
at least 15 minutes prior to touching any part of the Touch
Screen display.
Once these steps have been completed, the correct operation of
the entire weather system is ensured.
3.2.3 Cable Connection:
When operating a completely wired system, (cable connection
between Base Station and Thermo-Hygro, as well as a
connection between the individual sensors) power will be
supplied not only to the Base Station but to the all of the sensors
as well when the AC adapter is used.
Note:
Operating the system directly wired while powering the
Base Station solely by batteries is not recommended due to the
considerably higher power consumption of the wired
configuration. The batteries may however remain in the Base
Station 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 Base Station will recognize this change and will
automatically switch to the appropriate operating mode.
3.3 System Start
After inserting the batteries or connecting the AC adapter, the
LCD will display all of the digital segments for a few seconds.
Immediately after this the Base Station will enter a test mode
during which all measured and received weather data is cycled
through, updated and displayed for a period of approximately 15
minutes.
During this test mode, the unit will not receive the WWVB time
signal.
