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

3. Observing the correct polarity install 2 AA batteries. The batteries
will fit tightly (to avoid start-up problems make sure they do not
spring free).
4. Replace the battery cover by sliding upwards. Be sure battery cover
is on securely.
B. Wireless Weather Station
1. Remove the battery cover (the cover has white writing on it).
2. Observe the correct polarity, and install two Alkaline AA batteries.
3. Do not press any buttons for at least ten minutes. If a button is
pressed before the indoor weather station has received informa-
tion from the TX29U-IT sensor, no data will be received from that
sensor until reset.
4. Replace the battery cover.

* 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 recep-
tion 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 tem-
perature 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 in-
door weather station while it is searching for the signal.
4. The time and date can be manually set. Once the signal is captured,
it will override any time and date set to the time zone selected.
5. Once the time and date are set, the Wireless Weather Station will
conduct a search every night at midnight and correct to the accu-
rate time and date (Daylight Saving Time is automatic). If the signal
has been received in the past 24 hours, the reception indicator will
be displayed. After a successful reception, no more reception at-
tempt would be made until the following day.
