Note:

Sensor must be outside to transmit outdoor temperature.

The sensor reads data from the environment it is currently in.

SETTING UP:

When one transmitter is used

1. First, insert the batteries into the Temperature transmitter (see “Install and replace batteries in the Temperature transmitter“).

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. Next, the time shows 12:00 and the "Weather girl" 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, the Weather station will start receiving data from the transmitter. The outdoor temperature 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.

4. In order to ensure sufficient 915 MHz transmission however, this should under good conditions be a distance no more than 330 feet (100 meters) in open air between the final position of the Weather Station and the transmitter (see notes on “Positioning” and “915 MHz Reception”).

5. Once the remote temperature has been received and displayed on the Weather station, the WWVB time (radio controlled time) code reception is automatically started. This takes typically between 3-5 minutes in good conditions. If after 10 minutes, the WWVB time has not been received, press the SET key to manually enter a time initially.

When more than one transmitter is used

1. User shall remove all the batteries from the Weather Station and transmitters and wait for 60 seconds if setting has been done with one transmitter before.

2. Insert the batteries to the first transmitter.

3. Within 30 seconds of powering up the first transmitter, insert the batteries to the Weather Station. Once the batteries are in place, all segments of the LCD will light up briefly. Following this, the time (shown as 12:00) and the weather girl icon will be displayed. If they are not shown in the LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them.

4. The outdoor temperature from the first transmitter (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 batteries to the second transmitter as soon as the outdoor temperature readings from the first transmitter are displayed on the Weather station.

Note: User must insert the batteries into the second transmitter within 10 seconds of reception of the first transmitter.

6. The outdoor data from the second transmitter and the "channel 2" icon should then be displayed on the Weather station. If this does not happen after 2 minutes, the batteries will need to be removed from all the units and reset from step 1.

7. Insert the batteries in the third transmitter as soon as the "channel 2" icon and outdoor data are displayed on the Weather station. Within 2 minutes, the channel 3 outdoor data from the third transmitter will be displayed and the channel icon will shift back to "1". If this does not happen, you must restart from step 1.

Note: User must insert the batteries into the third transmitter within 10 seconds of reception of the second transmitter.

8. In order to ensure sufficient 915 MHz transmission however, this should under good conditions be a distance no more than 330 feet (100 meters) in open air between the final position of the Weather Station and the transmitter (see notes on “Positioning” and “915 MHz Reception”).

9. Once the remote temperature has been received and displayed on the Weather station, the WWVB time (radio controlled time) code reception is automatically started. This takes typically between 6-8 minutes in good conditions.

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 the setup again from step 1.

Note: Daily WWVB reception (Atomic time) is attempted at the top of each hour between 12:00 am to 6:00 am. If the reception is successful, there is no reception attempt until the following day. When this is successful, the received time will override the manually set time. The date is also updated with the received time. (Please also refer to the notes on “WWVB Radio Controlled time” and “Manual Time Setting”)

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 international standard, measuring a second as 9.192.631.770 vibrations of a Cesium-133 atom in a vacuum. This atomic clock regulates the WWVB transmitter.

Note: If the WWVB tower icon flashes on the top left of the LCD, but does not set the time or the tower does not appear at all, then please note the following:

 Recommended distance from any interfering sources like computer monitors or TV

sets is a minimum of 6 feet (2 meters).

 With ferro-concrete rooms (basements, superstructures), the received signal is

naturally weakened. In extreme cases, please place the unit close to a window and/ or point its front or back towards the Fort Collins, Colorado transmitter.

 During nighttime, the atmospheric disturbances are usually less severe and reception

is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.

 In case the Weather Station is not able to detect the WWVB-signal (disturbances,

transmitting distance, etc.), the time can be manually set (please refer to the notes on

Manual time setting).

WEATHER FORECAST AND TENDENCY: The weather forecast icons (Weather girl):

One of the 15 different weather icons (featured by Weather girl with different clothing) 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):

Sunny

 78.8F 66.2 – 78.6F

50 – 66F

32 – 49.8F< 32F

Sunny +

Cloudy

Cloudy +

Rainy

 78.8F 66.2 – 78.6 F

 78.8F 66.2 – 78.6F

50 – 66F

32 – 49.8F< 32F

32 – 49.8F < 32F

For every sudden or significant change in the air pressure, the weather icons will update accordingly to represent the change in weather. If the icons do not change, then it means either the air pressure has not changed or the change has been too slow for the Weather Station to register. However, if the icon displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes.

The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not necessarily rainy.

Note: After setting up, readings for weather forecasts should be disregarded for the next 4860 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).

If 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 floors 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 arrow located near the Weather girl). When the indicator points upwards, it means that the air-pressure is increasing and the weather is expected to improve, but when indicator points downwards, the air-pressure is dropping and the weather is expected to become worse.

Therefore, 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, it means that 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.

TEMPERATURE TRANSMITTER:

The range of the Temperature transmitter may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when placing the transmitter.

915 MHz RECEPTION

If the outdoor temperature data is not being received within 5 minutes after setting up (the display shows ‘’ - -. - F’’ on the outdoor section for a long time

check the following items:

1. The distance of the Weather Station or transmitter should be at least 5 to 6.5 feet 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.

3. 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 transmitter 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.

during normal operation) please

The transmission range is about 330 feet (100 m) from the transmitter to the Weather Station (in open space). However, this depends on the surrounding environment and interference levels. If no reception is possible despite the observation of these factors, all system units have to be reset (see Setting up).

Note:

Sensor must be outside to transmit outdoor temperature. The sensor reads data from

the environment it is currently in.

POSITIONING

TEMPERATURE TRANSMITTER:

The Transmitter is supplied with a holder that may be attached to a wall with the two screws supplied. The Transmitter can also be position on a flat surface by securing the stand to the bottom to the Transmitter.

To wall mount:

1. Secure the bracket onto a desired wall using the screws and plastic anchors.

2. Clip the remote temperature sensor onto the bracket.

Note:

Before permanently fixing the transmitter 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 transmitters or move them slightly as this may help the signal reception.

POSITIONING THE WE ATHER STATION:

The Weather Station comes complete with a foldout stand that gives the option of table standing or wall mounting.

To wall mount:

1. Fix a screw into the desired wall, leaving the head extended out about 0.2” (5mm).

2. Using the Weather Station’s hanging hole, carefully hang it onto the screw.

Note:

Always ensures that the unit locks onto the screw head before

releasing.

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.

 Precautions shall be taken when handling the batteries. Injuries, burns, or property

damage may be resulted if the batteries are in contact with conducting materials, heat, corrosive materials or explosives. The batteries shall be taken out from the unit before the product is to be stored for a long period of time.

 Immediately remove all low powered batteries to avoid leakage and damage. Replace

only with new batteries of the recommended type.

 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.  Special care shall be taken when handling a damaged LCD display. The liquid crystals

can be harmful to user's health.

 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.

 Never touch the exposed electronic circuit of the device as there is a danger of electric

shock should it becomes exposed.

 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.
