SETTING UP:

When one Sensor is used

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

2. Immediately after and within 30 seconds, insert the batteries into Temperature Station (see “Install and replace batteries in the Temperature Station”). Once the batteries are in place, all segments of the LCD will light up briefly. Following the

time as 12:00 and the indoor temperature 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 Temperature Station will start

receiving data from the sensor. The outdoor temperature and the signal reception icon should then be displayed on the Temperature 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 however, there should be no more

than 330 feet (100 meters) between the final position of the Temperature Station and the sensor (see notes on “Mounting” and “915 MHz Reception”).

5. Once the remote temperature has been received and displayed on the Temperature

Station, the WWVB time code reception is automatically started. This takes typically between 3-5 minutes in good conditions—but may take up to 4 nights.

When more than one sensor is to be used

1. User shall remove all the batteries from the Temperature Stati on 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

Temperature Station. Once the batteries are in place, all segments of the LCD will

light up briefly. Following time as 12:00 and the indoor temperature 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 from the first sensor (channel 1) should then be displayed

on the Temperature 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)

the reading form the first sensor is shown on LCD.

6. The outdoor temperature from the second sensor and the "channel 2" icon should

then be displayed on the Temperature 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 after)

ithe reading from the second sensor is shown on LCD.

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

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 Temperature Station and the sensor (see notes on “Mounting” and “915 MHz Reception”).

Note:

• 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.

• 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.

10. Once the remote temperature has been received and displayed on the Temperature

Station, the WWVB time code reception is automatically started. This takes typically between 3-5 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 follow the set-up from step 1.

• If after 10 minutes, the Atomic auto-set time (WWVB time) 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 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 TEMPERATURE STATION

The Temperature Station uses 2 x AAA, IEC LR3, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Remove the cover at the back of the Temperature Station.

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

3. Replace compartment cover.

INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE SENSOR

The temperature sensor uses 2 x AA, IEC LR6, 1.5V battery. To install and replace the batteries, please follow the steps below:

1. Remove the battery compartment cover.

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

3. Replace the battery cover 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 Temperature 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 (Batter y life see Specifications below).

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

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 Temperature 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. After the top of the minute, a tone will sound for every second. It is possible that your

Wireless Temperature 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.
