SETTING UP

WHEN ONE TRANSMITTER IS USED

1. First, insert the batteries in the transmitter (see “How to install and replace batteries in the Thermo-hygro outdoor transmitter”on

page 11).

2. Within 2 minutes of powering up the transmitter, insert the batteries in the Weather Station (see “How to install and replace batteries

in the Weather Station” on pages 11-12). Once the batteries are in place, all segments of the LCD will light up briefly and a short signal tone will sound. Following the indoor temperature/humidity and the time, as 12:00 will be displayed. If this information is not displayed on the LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. Once the indoor data is displayed user may proceed to the next step.

3. After the batteries are inserted, the Weather station will start receiving data signal from the transmitter. The outdoor temperature and humidity data should then be displayed on If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1.

4. The distance between the Weather Station and the transmitter should not be more than 300 feet to ensure sufficient 915 MHz transmission. (see notes on “Positioning” and “915 MHz

Reception”).

Note:

In the event of changing batteries of the units, ensure the batteries do not spring free from the contacts. Always wait at least 1 minute after removing the batteries before reinserting, otherwise start up and transmission problems may occur.

the Weather station.

WHEN MORE THAN ONE TRANSMITTER IS USED

1. User shall remove all the batteries from the Weather Station and transmitters, and wait 60 seconds.

2. Insert the batteries in the first transmitter.

3. Within 2 minutes of powering up the first transmitter, insert the batteries in the Weather Station. Once the batteries are in segments of the LCD will light up briefly and a short signal tine will sound. Following the indoor temperature/humidity and the time as 12:00 will be displayed. If this information is not displayed on the LCD after 60 seconds, remove the batteries from both units and wait for at least 60 seconds before reinserting them.

4. The outdoor temperature and humidity data from the first transmitter (channel 1) and the signal reception icon displayed on the Weather Station. 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 in the second transmitter as soon as the signal reception icon Station. Then within 2 minutes, the channel 2 outdoor data from the second transmitter and the "channel 2" icon should be displayed on the Weather Station. If this does not happen after 2 minutes, the

and outdoor data are displayed on the Weather

place, all

batteries will need to be removed from all the units and reset from step 1.

Note :

User shall insert the batteries into the second transmitter within 45 seconds after the Weather Station displays the information of the first transmitter.

6. Insert the batteries in the third transmitter 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 transmitter will be displayed and the channel icon will shift back to "1" once the third transmitter is successfully received. If this is not happen, user shall restart the setting up from step 1.

User shall insert the batteries into the third transmitter within

Note :

45 seconds after the Weather Station displays the information of the first transmitter. Or immediately after reception of the second transmitter is finished.

7. The distance between the Weather Station and the transmitter should not be more than 300 feet to ensure sufficient 915 MHz transmission. (see notes on “Positioning” and “915 MHz

Reception”).

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.

Note:

x If the signal reception is not successful on the first frequency of

915MHz for 45 seconds, the frequency is changed to 920MHz and the learning is tried for another 45 seconds. If it is still not successful the reception is tried for 45 seconds on 910MHz. This will also be done during re-synchronization.

x When the weather station is receiving the WWVB time signal, the

outdoor transmitter data signal will temporarily not be received by the weather station. During this short period of time, the outdoor readings shown on the weather station will not be renewed until the WWVB time signal is successfully received.

TO INSTALL AND REPLACE BATTERIES IN THE THERMOHYGRO TRANSMITTER

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 due to a random security code assigned by the transmitter at start-up. This code must be received and stored by the Weather Station in the first 3 minutes of power being supplied to the transmitter.

The Thermo-Hygro Transmitter uses 2 x AA, IEC, LR6,

1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Remove the cover.

2. Insert the batteries, observing the correct polarity (see marking).

3. Replace the battery cover.

TO INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The Weather Station uses 2 x C, IEC LR14, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Insert finger or other solid object in the space at the bottom center of the battery compartment and lift up to remove the cover.

2. Insert batteries observing the correct polarity (see marking).

3. Replace compartment cover.

BATTERY CHANGE:

It is recommended to replace the batteries in all units on an annual basis to ensure optimum accuracy of these units.

Please participate in the preservation of the

environment. Return used batteries to an authorized depot.

RESETTING

The Weather Station and the Thermo-hygro transmitter need to be reset when one of the following conditions occur:

x Unsuccessful 915 MHz signal reception. x Malfunction on the units. x Batteries replacement.

For resetting, remove all batteries from the units. Wait at least for 1 minute before powering up the Weather station again. Proceed from step 1 in “Setting Up”.

ABOUT 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 projection 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 Cesium133 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.
