First, insert the battery into the thermo-hygro sensor. (see “Install and replace batteries in the thermo-hygro sensor“).
92. 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 battery into the sensor, the Weather Station will start receiving data from the sensor. The outdoor temperature/ humidity and the signal reception icon should then be displayed on the Weather Station. If this does not happen after 15 minutes, the batteries will need to be removed from both units and reset from step 1.
104. In order to ensure sufficient 915 MHz transmission there should be a distance of 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”). 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 into 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
11and wait for at least 60 seconds before reinserting them. 4. The outdoor temperature and humidity from the first sensor (channel 1) should then be 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 battery into the second sensor immediately after (within 10 seconds after) inserting battery to the Weather Station. 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 into the third sensor immediately after (within 10 seconds
12after) inserting battery to the second sensor. 8. 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 sensor is successfully received. If this is not happen, user shall restart the setting up from step 1. 9. In order to ensure sufficient 915 MHz transmission there should be a distance of 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: After the three sensors have been set up, user may need to check the readings displayed on the Weather Station against those being shown on the sensor displays, in
13order to recognize which channel each sensor is displayed. 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 for another 45 seconds. If still not successful the reception is tried for 45 seconds on 910MHz. This will also be done for re-synchronization. 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 follow the set-up from step 1.
1410. Once the remote temperature has been received and displayed on the Weather Station, the WWVB time code reception is automatically started. This takes typically between 6-8 minutes in good conditions. (Depending on location, it may take up to four nights to first receive the WWVB signal.) 11. If after 10 minutes, the WWVB time has not been received, press the SET key to manually enter a time initially. Note: Daily WWVB reception is attempted for a full hour between 12:00 am to 6:00 am. If the reception is not successful, there will no further reception attempt until the following day. When this is successful, the received time will override the manually set time. The
15date is also updated with the received time. (Please refer also to notes on “WWVB Radio controlled Time” and “Manual Time Setting”). The Outdoor Thermo-hygro Sensor • Remote transmission of outdoor temperature and humidity to Weather Station by 915 MHz • LCD alternates between temperature and humidity readings. • Water-resistant casing • Wall mounting case • Mount in a sheltered location. Avoid direct rain and sunlight
16BATTERY INSTALLATION INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION The Weather Station uses 2 x AAA, 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.
17INSTALL AND REPLACE BATTERIES IN THE THERMO-HYGRO SENSOR The Thermo-hygro Sensor uses 1 x 3.0V IEC CR2032, Lithium battery. To install and replace the battery, please follow the steps below: 1. Pull out the battery holder at the bottom of the sensor. 2. Insert the battery, 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.

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
26projection 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
27(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 • Time reception ON/OFF setting

Confirm with the SET key and exit the Manual settings. WEATHER FORECAST AND TENDENCY: The weather forecast icons (Oscar Outlook): One of the 15 different weather icons (featuring Oscar Outlook with different clothing suggestions) is displayed in the centre of LCD, which indicates the different forecast weather condition due to air pressure level (Sunny, Sunny + Cloudy or Cloudy + Rainy) and the current outdoor temperature (Temperature value detected by Channel 1):
43 ≥≥≥≥ 78.8°°°°F (26°°°°C) 66.2 – 78.6°°°°F (19 – 25.9°°°°C) 50-66°°°°F (10 – 18.9°°°°C) 32 – 49.8°°°°F (0 – 9.9°°°°C) < 32°°°°F (0°°°°C) Sunny
44 ≥≥≥≥ 78.8°°°°F (26°°°°C) 66.2– 78.6°°°°F (19 –25.9°°°°C) 50-66°°°°F (10– 18.9°°°°C) 32 – 49.8°°°°F (0 – 9.9°°°°C) < 32°°°°F (0°°°°C) Sunny + Cloudy
45 ≥≥≥≥ 78.8°°°°F (26°°°°C) 66.2 – 78.6°°°°F (19 –25.9°°°°C) 50-66°°°°F (10 – 18.9°°°°C) 32 – 49.8°°°°F (0 – 9.9°°°°C) < 32°°°°F (0°°°°C) Cloudy + Rainy
46Note: After setting up, readings for weather forecasts should be disregarded for the next 48-60 hours. This will allow sufficient time for the Weather Station to collect air pressure data at a constant altitude and therefore result in a more accurate forecast. Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting feature is estimated to have an accuracy level of about 75% due to the varying areas the Weather Station has been designed for use in. In areas that experience sudden changes in weather (for example from sunny to rain), the Weather Station will be more accurate compared to use in areas where the weather is stagnant most of the time (for example mostly sunny).
47If the Weather Station is moved to another location significantly higher or lower than its initial standing point (for example from the ground floor to the upper floor of a house), remove the batteries and re-insert them after about 30 seconds. By doing this, the Weather Station will not mistake the new location as being a possible change in air-pressure when really it is due to the slight change of altitude. Again, disregard weather forecasts for the next 48-60 hours as this will allow time for operation at a constant altitude. THE WEATHER TENDENCY INDICATOR Working together with the weather icons are the weather tendency indicators (the upward and downward arrows located near Oscar Outlook). When the indicator points upwards, the air-pressure is increasing and the weather is expected to improve, but
48when indicator points downwards, the air-pressure is dropping and the weather is expected to become worse. Therefore, the user may see how the weather has changed and is expected to change. For example, if the indicator is pointing downwards together with cloudy icons, the last noticeable change in the weather was when it was sunny (the sunny icon only). Therefore, the next change in the weather will be the cloudy icons since the indicator is pointing downwards. Note: Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD.

If the temperature data is not received 15 minutes after setting up (not successfully continuously, the outdoor display shows “- - -” ), please check the following points: 1. The distance of the weather station or sensor should be at least 1.5 to 2 meters away from any interfering sources such as computer monitors or TV sets. 2. Avoid positioning the Weather Station onto or in the immediate proximity of metal window frames.
603. Using other electrical products such as headphones or speakers operating on the same signal frequency (915MHz) may prevent correct signal transmission and reception. 4. Neighbors using electrical devices operating on the 915MHz signal frequency can also cause interference. Note: When the 915MHz signal is received correctly, do not re-open the battery cover of either the sensor or Weather Station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Setting up above) otherwise transmission problems may occur. The transmission range is about 330 feet (100 m) from the sensor to the Weather Station (in open space). However, this depends on the surrounding environment and
61interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up). MOUNTING POSITIONING THE WEATHER STATION: The Weather Station has been designed to be hung onto a wall or free standing. To wall mount Choose a sheltered place. Avoid direct rain and sunshine. Before wall mounting, please check that the outdoor temperature and humidity values can be received from the desired locations.
621. Fix a screw (not supplied) into the desired wall, leaving the head extended out the by about 5mm. 2. Remove the stand from the Weather Station by pulling it away from the base and hang the station onto the screw. Remember to ensure that it locks into place before releasing.
63Free standing With the detachable stand, the Weather Station can be placed onto any flat surface.
64POSITIONING THE THERMO-HYGRO SENSOR: The sensor is supplied with a holder that may be attached to a wall with the two screws supplied. The sensor can also be position on a flat surface by securing the stand to the bottom of the sensor.
65To wall mount: 1. Secure the bracket onto a desired wall using the screws and plastic anchors. 2. Clip the remote thermo-hygro sensor onto the bracket.
66Note: Before permanently fixing the sensor wall base, place all units in the desired locations to check that the outdoor temperature reading is receivable. In event that the signal is not received, relocate the sensors or move them slightly as this may help the signal reception. CARE AND MAINTENANCE: • Extreme temperatures, vibration and shock should be avoided as these may cause damage to the unit and give inaccurate forecasts and readings. • When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scouring agents as they may mark the LCD and casings. • Do not submerge the unit in water.
67• Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended type. • Do not make any repair attempts to the unit. Return them to their original point of purchase for repair by a qualified engineer. Opening and tampering with the unit may invalidate their guarantee. • Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes in forecasts and readings and thereby reduce their accuracy.
