The Outdoor Temperature Sensor
•
Remote transmission of outdoor temperature to Weather
Station by 915 MHz
•
Weather-resistant casing
•
Wall mounting case
•
Mount in a sheltered place. Avoid direct rain and sunshine
SETTING UP:
1. First, insert the batteries into the temperature sensor. (see “Install and replace
batteries in the temperature sensor“).
2. Immediately after and within 2 minutes, insert the batteries into Weather Station (see
“Install and replace batteries in the Weather Station”). Once the batteries are in
place, all segments of the LCD will light up briefly. Following the time as 12:00 and
the "Oscar Outlook" icon will be displayed. If these are not displayed after 60
7
seconds, remove the batteries and wait for at least 10 seconds before reinserting
them.
3. After inserting the batteries into the sensor, the Weather Station will start receiving
data from the sensor. The outdoor temperature and the signal reception icon should
then be displayed on the Weather Station. If this does not happen after 5 minutes, the
batteries will need to be removed from both units and reset from step 1.
4. In order to ensure sufficient 915 MHz transmission there should be no more than 330
feet (100 meters) between the final position of the Weather Station and the sensor
(see notes on “Mounting” and “915 MHz Reception”).
Note:
•
The Weather Station will receive one outdoor sensor only.
•
If the signal reception is not successful on the first frequency (915MHz) for 22
seconds, the frequency is changed to 920MHz and the reception is tried another 22
seconds. If still not successful the reception is tried for 22 seconds on 910MHz. This
will also be done for re-synchronization.
•
If after 10 minutes, the Atomic time (WWVB time) signal has not been received, press
the SET key to manually enter a time initially.
•
Daily WWVB reception is attempted at full hour between 12:00 am to 6:00 am. If the
reception is successful, there will no reception attempt until the following day. When
this is successful, the received time will override the manually set time. The date is
8
also updated with the received time. (Please refer also to notes on “Atomic auto-set
time - WWVB Radio controlled Time” and “Manual Time Setting”).
BATTERY INSTALLATION
INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION
The Weather Station uses 2 x AAA, IEC LR3, 1.5V Alkaline batteries. To install and replace
the batteries, please follow the steps below:
1. Remove the cover at the back of the Weather
Station.
2. Insert batteries observing the correct polarity (see
marking).
3. Replace compartment cover.
9
INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE SENSOR
The temperature sensor uses 2 x AA, IEC LR6, 1.5V Alkaline battery.
To install and replace the batteries, please follow the steps below:
1. Pull out the battery holder at the bottom of the sensor.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery holder on the unit.
Note:
In the event of changing batteries in any of the units, all units need to be reset by following
the setting up procedures. This is because a random security code is assigned by the
sensor at start-up and this code must be received and stored by the Weather Station in the
first 3 minutes of power being supplied to it
BATTERY CHANGE:
It is recommended to replace the batteries in all units regularly to ensure optimum accuracy
of these units (Battery life see Specifications below).

Please participate in the preservation of the environment. Return used
batteries to an authorized depot.

* When the outdoor signal is successfully received by the Weather Station, this icon will be
switched on. (If not successful, the icon will not be shown in LCD) 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 currently taking place.
For easy viewing, the LCD screen is divided into 3 sections displaying the information for
time and indoor data, weather forecast, and outdoor data.
Section 1 - OUTDOOR TEMPERATURE
•
Display the current outdoor temperature.
•
By pressing the MIN/ MAX key, display the stored MIN/MAX outdoor temperature,
with simultaneous display of MIN/ MAX icon.
•
A signal reception symbol will be shown indicating that outdoor temperature signal is
received.
Section 2 - INDOOR DATA AND WEATHER ICON (FEATURED BY WEATHER GIRL)
•
Display indoor temperature and indoor humidity
•
The current temperature condition is displayed in form of one of multiple icons,
featured by Weather Girl, which change in appearance according to the current
outdoor temperature.
•
Format of the Oscar Outlook icons refers to the below clause "Weather Girl"

Section 3 - TIME AND CALENDAR
•
In normal mode, display the time and calendar.
•
A signal reception symbol is shown indicating that Atomic time (WWVB time) signal is
received.
ATOMIC TIME - WWVB RADIO CONTROLLED TIME
The NIST (National Institute of Standards and Technology—Time and Frequency Division)
WWVB radio station is located in Ft. Collins, Colorado, and transmits the exact time signal
continuously throughout the United States at 60 kHz. The signal can be received up to
2,000 miles away through the internal antenna in the Weather Station. However, due to the
nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The
wireless weather station will search for a signal every night when reception is best.
The WWVB radio station receives the time data from the NIST Atomic clock in Boulder,
Colorado. A team of atomic physicists is continually measuring every second, of every day,
to an accuracy of ten billionths of a second per day. These physicists have created an
international standard, measuring a second as 9,192,631,770 vibrations of a Cesium-133
atom in a vacuum. For more detail, visit http://www.boulder.nist.gov/timefreq.htm. To listen
to the NIST time, call (303)499-7111. This number will connect you to an automated time,
announced at the top of the minute in “Coordinated Universal Time”, which is also known
as Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time changes.
