is not displayed on the LCD after 60
seconds, remove the batteries and wait
for at least 60 seconds before reinserting
them. Once the indoor data is displayed
user may proceed to the next step.
3.
After the batteries are inserted, the
thermo-hygrometer will start receiving
data signal from the transmitter. The
outdoor temperature and humidity data
should then be displayed on the thermo-
hygrometer. 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, the distance
between the thermo-hygrometer and the
transmitter should not be more than 100
meters (see notes on “
Positioning” and
“868 MHz Reception
”).
Note:
In the event of changing batteries of the
units, ensure the batteries do not spring
free from the contacts. Always wait at
least 1 minute after removing the batteries
before reinserting, otherwise start up and
transmission problems may occur.
5.
Once the outdoor data reception test
period is completed, the DCF tower icon
in the clock display will start flashing in the
upper left corner. This indicates that the
clock has detected that there is a radio
signal present and is trying to receive it.
