TO INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER

 

The transmitter uses 2 x AA,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 inside battery compartment).
3. Replace the battery cover on the unit.Alkaline batteries are recommended for use in both units. Avoid using rechargeable batteries.SETTING UP:

NOTE: Do not set the clock until the outdoor temperature is displayed.

1. Place batteries in the outdoor transmitter first, then into the atomic clock. DO NOT PRESS ANY BUTTONS FOR 10 MINUTES.

2. After 10 minutes both the Indoor and Outdoor areas on your clock should have a temperature showing. If not, remove both sets of batteries, wait 10 minutes and repeat step one.
3. After the clock receives the outdoor temperature, and 10 minutes has elapsed, set your time zone. The default time zone is Eastern Standard Time (EST). If you live in the Eastern Time zone move to step 5.
4. To set the time zone:
• Push and release the “SET” function button.
• The time zone (LCD2) will start flashing (Default setting -5EST).
• Push the (+) function button to change the default setting (-5EST) to the desired time zone.-6 CST (Central Time Zone)-7 MST (Mountain Time Zone)

-8 PST (Pacific Time Zone)

(See “Time Zone Setting” if you live outside the USA)

5. After the clock receives the outdoor temperature the WWVB time code reception will automatically start. The clock will automatically set itself to the exact time, day and date after receipt of the WWVB time code reception. This typically takes over night. For best reception place your clock next to a window facing Colorado over night. Once a successful reception is received the Radio Reception ( ) icon will appear above the blinking colons. Once a successful reception is received relocate your clock to a desired location. The clock will then automatically attempt to receive the WWVB time from 12:00 am through 6:00 am each day (attempts WWVB reception every full hour within this time frame). When this is successful, the received time will override the manually set time. The date is also updated with the received time (Please refer to notes on “Radio controlled time” and “Manual time setting”).
Note:In the event of changing batteries of the unit ensure that the batteries do not spring free from the contacts. Always wait at least 10 minutes after removing the batteries before reinserting, otherwise start up and transmission problems may occur.

• -7 MST (Mountain time),
• -8 PST (Pacific time),
• -9 ALA (Alaska time),
• -10 HAW (Hawaii time).
• “GMT” will be displayed if set to GMT (0).
2. Press and release the SET key to enter the “DST Setting“.DST SETTING (daylight saving time)
1. The ON digit will start flashing on LCD1. Set the DST ON or OFF by pressing the + key.
2. Press and release the SET key to enter the “Language Setting“.Note:

The DST default is “ON”, meaning that the WWVB will automatically change the time according to Daylight Saving Time in the spring and fall. For areas that do not recognize DST changes (Arizona and parts of Indiana) turn the DST “OFF”.

LANGUAGE SETTING

The weekdays can be displayed in LCD2 with the pre-set languages: English, French, Spanish and German.

US = English

F = French

E = Spanish (Espanol)

D = German (Deutsch)

1. Set the desired language for the weekday display in LCD 2 by use of the + key.
2. Press and release the SET key to enter the mode “Manual Time Setting”.

MANUAL TIME SETTING

 

In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the time can be manually set. The clock will then work as a normal Quartz clock.

Note: In 12 hours mode the time will be displayed with an additional “PM” for the time from 12:00 noon until 11:59 pm.

1. The hour digits will start flashing on LCD1.
2. Set the desired hours by pressing and releasing the + key followed by pressing the SET key.
3. Now the minute digits will start flashing.
4. Set the desired minutes by pressing and releasing the + key. If the + key is held, the units will increase by 5.
5. Press and release the SET key to move to the “Year Setting”.Note:

The unit will still try and receive the signal every day despite it being manually set. When it does receive the signal, it will change the manually set time into the received time. During reception attempts the WWVB tower icon will flash. If reception has been unsuccessful, then the WWVB tower icon will not appear but reception will still be attempted the following hour.

WWVB time reception takes place from 12:00 am through 6:00 am each day (attempts WWVB reception every full hour within this time frame). When the time signal is received for example at 1:00 am, the atomic clock will not attempt to receive the WWVB signal for the remaining hours until 6:00 am. Therefore, the next signal attempt will take place between 12:00 am and 6:00 am the next day. The other times WWVB reception takes place, are upon setup and after manual time set exiting mode. Reception is generally not possible during daylight hours due to the interference of the sun.

YEAR SETTING

The year can be selected sequentially from 2000 to 2049 and will then start over again (default setting 2000). Only the last 2 digits of the year will be visible on LCD2.

The snooze can only be activated during alarm time for a snooze duration of 10 minutes by pressing the SNZ key on the back of the clock

OUTDOOR TEMPERATURE TRANSMITTER:

 

The temperature is measured and transmitted to the atomic clock every 1 minute. The atomic clock will update the temperature display every 5 minutes.

The range of the outdoor temperature transmitter may be affected by the temperature. At cold temperatures the transmitting distance may be decreased. Please bear this in mind when positioning the transmitter. Also the batteries may be reduced in power during periods of extreme cold temperatures.

433MHz RECEPTION CHECK FOR OUTDOOR TEMPERATURE TRANSMITTER

 

The atomic clock will receive the temperature data within 10 minutes. If the temperature data is not received 10 minutes after setting up (the display shows “- – -”), then please check the following points:

1. The distance of the atomic clock or outdoor temperature transmitter should be at least 6 feet away from any interfering sources such as computer monitors or TV sets.

2. Avoid placing the receiver 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 (433MHz) may prevent correct signal transmission and reception.

4. Neighbors using electrical devices operating on the 433MHz signal frequency can also cause interference.

Note:

 

When the 433 MHz signal is received correctly, do not re-open the battery cover of either the outdoor temperature transmitter or atomic clock, 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 maximum transmission range is 200 feet from the outdoor temperature transmitter to the atomic clock (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). See our website
www.skyscaninfo.com

for more information.

CHANGING THE DISPLAY MODE (DAY, SECONDS, AND TEMPERATURES) There are four possible display modes to view the day, seconds, and temperatures.

The month&date/weekday/indoor temperature/outdoor temperature is the default.

To change the display:

1. Press the + key. The display should now show the month&date/weekday/seconds/outdoor temperature.
2. Press the + key a second time and the display will now show the month&date/weekday/indoor temperature/seconds.
3. Press the + key third time and the display will now show the month&date/seconds/indoor temperature/outdoor temperature
4. Press the + key a fourth time and the display will return to the default display.

WWVB RADIO CONTROLLED TIME

 

The NIST radio station, WWVB, 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 atomic clock. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The atomic clock will search for a signal every night when reception is best. The WWVB radio station derives its signal from the NIST atomic clock in Boulder, Colorado. A team of atomic physicists continually measures every second of every day to an accuracy of ten billionths of a second a 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.

Once the outdoor temperature is displayed on the atomic clock, the WWVB tower icon in the clock display will start flashing in the top center of the LCD. This indicates that the clock has detected a radio signal and is trying to receive it. When the time code is received, the WWVB tower becomes permanently lit and the time will be displayed.

If the tower icon flashes, but does not set the time or the WWVB tower does not appear at all, then please take note of the following:

• Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 6 feet.
• Within 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.Note:

In case the atomic clock is not able to detect the WWVB-signal (disturbances, transmitting distance, etc.), the time can be manually set (please refer to notes on Manual time setting) .

ICON DESCRIPTION:

 

POSITIONING

 

Before permanently mounting ensure that the atomic clock is able to receive WWVB signals from the desired location. Also, extreme and sudden changes in temperature will decrease the accuracy of the atomic clock, and changes in elevation will result with inaccurate temperatures readings for the next 12 to 24 hours. These changes will require a 12 to 24 hour wait before obtaining reliable data.

POSITIONING THE ATOMIC CLOCK:

 

There are two possible ways to mount the atomic clock:

• use of the foldout table stand, or
• wall mounting
FOLDOUT TABLE STANDThe foldout table stand leg is located on the backside. Pull the stand out from the bottom center edge of the atomic clock, below the battery compartment. Once the foldout table stand is extended, place the atomic clock in an appropriate location.

WALL MOUNTING

 

1) Using a straightedge, horizontally space at 2.36 inches (60 mm) three screw positions on a wall.

2) Install three mounting screws (not included) into a wall within transmission range—leaving approximately 3/16 of an inch (5mm) extended from the wall.

3) Place the atomic clock onto the screws, using the hanging holes on the backside. Gently pull the atomic clock down to lock the screws into place.

Note:

 

Always ensure that the atomic clock locks onto the screws before releasing.

POSITIONING THE OUTDOOR TEMPERATURE TRANSMITTER

 

To achieve a true temperature reading, avoid mounting where direct sunlight can reach the outdoor temperature transmitter. It is recommended to mount the outdoor temperature transmitter on a North-facing wall or in any well shaded area. The maximum transmitting range is 200 feet obstacles such as walls, concrete, and large metal objects can reduce the range.

Place both units in their desired location, and wait approximately 10 minutes before permanently mounting to ensure that there is proper reception. The outdoor temperature transmitter is not waterproof and should not be placed anywhere it will become submerged in water or be directly in the rain.

The outdoor temperature transmitter can be mounted in two ways:

• with the use of screws, or
• using the adhesive tape.MOUNTING WITH SCREWS

1) Remove the mounting bracket from the outdoor temperature transmitter.

2) Place the mounting bracket over the desired location. Through the three screw holes of the bracket, mark the mounting surface with a pencil.
3) Where marked, start the screw holes into mounting surface.
4) Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the bracket.MOUNTING WITH ADHESIVE TAPE

1) With a nonabrasive solution, clean and dry the back of the mounting bracket and the mounting surface to ensure a secure hold. The mounting surface should be smooth and flat.

2) Remove the protective strip from one side of the tape. Adhere the tape to the designated area on the back of the mounting bracket.
3) Remove the protective strip from the other side of the tape. Position the outdoor temperature transmitter in the desired location, ensuring that the atomic clock can receive the signal.

TROUBLESHOOTING:

Problem:

The LCD is faint.

Solution:

1) Replace the batteries.

Problem:

No reception of WWVB signal

Solution:

1) It may help reception to face the front or back of the atomic clock in the general direction of Ft. Collins, Colorado.

2) Wait overnight for signal.

3) Be sure the atomic clock is at least 6 feet (2 meters) from any electrical devices, i.e. TV sets, computers, or other radio controlled clocks.

4) Remove batteries for ten minutes. See setting up.

Problem:

Hour is incorrect (minute and date are correct).

Solution:

1) Be sure the correct time zone and daylight saving time are selected.

Problem:

“OF.L“ appears in the indoor temperature section of the LCD

Solution:

1) Move the atomic clock to an area with warmer or cooler surrounding temperature. Current surrounding temperatures are outside measuring range.

Problem:

“–.-” appears in the outdoor temperature section of the LCD.

1) Remove the batteries of both units for ten minutes, then reinsert them again. Make sure the batteries are new and fresh. See setting up. 2) Move the atomic clock closer to the transmitter or place the transmitter closer to the atomic clock. Make sure the clock is at a receivable range from the transmitter.3) Move the units to another location. Interferences from other electrical devices operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception.

“OF.L“ appears in the outdoor temperature section of the LCD.

1) Wait until the current surrounding temperature cools down or increases. Current temperature is outside of the measuring range of the transmitter or has temporary affected battery strength. The outdoor temperature will be displayed again once the current surrounding temperature is within the range of the transmitter. CARE AND MAINTENANCE:• Avoid placing the units in areas prone to vibration and shock as these may cause damage.• Avoid areas where the units can be exposed to sudden changes in temperature, i.e. direct sunlight, extreme cold and wet/moist conditions as these will lead to rapid changes which reduces the accuracy of readings.• When cleaning the LCD and casing, use a soft damp cloth only.
