SETTING UP:
When one sensor is to be used
1. First, insert the batteries into the thermo-hygro sensor. (see “Install and replace
batteries in the thermo-hygro sensor “).
2. Immediately after and within 30 seconds, 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 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 humidity and the signal reception icon
should then be displayed on the Weather Station. If this does not happen after 3 minutes,
the batteries will need to be removed from both units and reset from step 1.
10
4. In order to ensure sufficient 915 MHz transmission however, this should under good
conditions be a distance no more than 100 meters between the final position of the
Weather Station and the sensor (see notes on “Mounting” and “915 MHz Reception”).
When more than one sensor is to be used
1. User shall remove all the batteries from the Weather Station and sensors and wait 60
seconds if setting has been done with one sensor before.
2. Insert the batteries to the first sensor.
3. Within 30 seconds of powering up the first sensor, insert the batteries to the Weather
Station. Once the batteries are in place, all segments of the LCD will light up briefly.
Following time as 12:00 and the Oscar Outlook icon will be displayed. If they are not shown
in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before
reinserting them.
4. The outdoor temperature and humidity from the first sensor (channel 1) should then be
11
displayed on the Weather Station. Also, the signal reception icon will be displayed. If this
does not happen after 2 minutes, the batteries will need to be removed from both units and
reset from step 1.
5. Insert the batteries to the second sensor as soon as the outdoor temperature readings from
the first sensor are displayed on the Weather Station.
Note: User shall insert the batteries into the second sensor within 30 seconds of reception of the
first .
6. The outdoor temperature and humidity from the second sensor and the "channel 2" icon
should then be displayed on the Weather Station. If this does not happen after 2 minute,
the batteries will need to be removed from all the units and reset from step 1.
7. Insert the batteries to the third sensor as soon as the "channel 2" icon and outdoor data are
displayed on the Weather Station. Then within 2 minutes, the channel 3 outdoor data from
the third sensor will be displayed and the channel icon will shift back to "1" once the third
12
sensor is successfully received. If this is not happen, user shall restart the setting up from
step 1.
Note: User shall insert the batteries into the third sensor within 30 seconds of reception of the
second sensor.
8. 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:
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 resynchronization.
13
IMPORTANT:
Transmission problems will arise if the setting for additional sensors is not followed as described
above. Should transmission problems occur, it is necessary to remove the batteries from all units
and start again the set-up from step 1.
9. Once the remote temperature has been received and displayed on the Weather Station, the
Atomic time (WWVB time) code reception is automatically started. This takes typically
between 3-5 minutes in good conditions.
Note:
• If after 10 minutes, the Atomic Time (WWVB) time has not been received, press the SET
key to manually enter a time initially.
• Daily WWVB reception (Atomic time) 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
14
also updated with the received time. (Please refer also to notes on “Atomic time WWVB Radio controlled Time” and “Manual Time Setting”)

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 startup 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.

ATOMIC TIME FUNCTION - 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 Wireless 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 internationa l standard,
24
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. After the top of the minute, a tone will sound for
every second. It is possible that your Wireless Weather Station may not be exactly on the second
due to the variance in the quartz. However, the clock will adjust the quartz timing over the course
of several days to be very accurate; under 0.10 seconds per day
MANUAL SETTINGS:
The following manual settings can be done in the setting mode:
• LCD contrast setting
• Time zone setting
• Daylight saving time setting
