Start Up Sequence - La Crosse Technology WS-7394U-IT Instruction Manual

Sensor signal
reception icon*
* When the signal is successfully received by the Weather Station, the icon will
be switched on. (If not successful, the icon will not be shown in LCD) So the user
can easily see whether the last reception was successful (icon on) or not (icon
off). On the other hand, the short blinking of the icon shows that a reception is
being done now.
•
If the signal reception is not successful on the first frequency (915MHz) for 45
seconds, the frequency is changed to 920MHz and the learning is tried another
45 seconds. If still not successful the reception is tried for 45 seconds on
910MHz. This will also be done for re-synchronization.
II. Start Up Sequence
A. Initial Start
1. Immediately after the batteries have been installed the LCD will
completely light up for a brief moment.
2. All information will then appear in normal mode, with "12:00" as
the default time and "SA.1" as the default date (2006 as the year).
3. The indoor temperature and humidity, and barometric air pressure
(as 29.92 inHg relative RH) will also be displayed.
4. There is a "satellite" icon that appears in the bottom portion of the
LCD, to the left of the outdoor temperature— this icon informs the
user that the indoor weather station is looking for signals from the
remote temperature sensor. Within five minutes the remote
temperature should be displayed—if not, remove batteries from all
units and repeat battery installation, the remote temperature sensor
first, then the indoor weather station.
B. WWVB Reception
1. Once the batteries are installed in the Wireless Weather Station it
will automatically search for the WWVB signal. If it receives a
good signal (which is unlikely during daylight hours in most
locations), the WWVB reception indicator (looks like a tower icon)
will flash. The Wireless Weather Station requires five full
minutes of good reception to successfully capture the signal and set
to the correct hour, minute, second, month, day and year. If the
signal reception is not successful within ten minutes, the signal
search will be cancelled. Next reception will take place the next
day.
2. The signal is sent from Ft. Collins, Colorado only and is similar to
an AM radio signal. Atmospheric interferences such as storms,
sunspots, and even sunlight will cause the signal to not travel as
far.
3. To maximize reception, place the Wireless Weather Station n in
a window facing Colorado, at least six feet from any electrical
source (computers, televisions, refrigerators, etc.). Do not move
the indoor weather station while it is searching for the signal.
