This procedure is repeated automatically up to total 5 times.

•To start manual WWVB signal reception, press the “WWVB SEARCH“ button. If no signals received within 7 minutes, then the WWVB signal search stops (the radio tower icon disappears) and will start again at the next full one-hour.

•To cancel RC reception and stop searching for the WWVB radio signal, press the “WWVB SEARCH“ button once. The radio tower icon will disappear.

About WWVB Radio Signal Reception:

•A flashing radio tower icon indicates that the WWVB signal reception has started.

•A continuously displayed radio tower icon indicates that the WWVB signal was received successfully during the last attempt. If the clock attempts to receive the WWVB signal and

Page 7 of 12

is unsuccessful, the tower icon will not be continuously displayed on the LCD.

•We recommend a minimum distance of 2.5 meters (8 feet) to all sources of interference, such as televisions or computer monitors

•Radio reception is weaker in rooms with concrete walls (e.g.: in cellars) and in offices. In such environments, place the system close to the window.

La Crosse Atomic Clock Instructions

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 the 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 the WWVB time code reception will automatically start. This reception typically takes between 5-10 minutes in good conditions. If after 10 minutes the WWVB time has not been received, use the “SET” key to manually enter the set-up mode and change either the time or date in order to activate the WWVB reception (see manual settings below). 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”).

4.After the time signal has been received or the search mode has been manually stopped the indoor temperature will be displayed.

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.

SNOOZE SETTING

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 4 minutes. If the temperature data is not being received 4 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 (2 meters) 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 82 feet (25 meters) 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).

CHANGING THE DISPLAY MODE (DAY, SECONDS, AND TEMPERATURES)

There are three 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/ indoor temperature.

2.Press the + key a second time and the display will now show the month&date/seconds/indoor temperature/outdoor temperature.

3.Press the + key third time and the display will return to the normal 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 (2 meters).

•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)

MOON PHASE

The Moon Phases, and their corresponding dates appear in LCD 2. There are 12 visible Moon Phases that will show in the LCD 2:

MOON PHASES FOR WS-8117

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.

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 82 feet (25 meters) 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.

POSITIONING THE ATOMIC CLOCK:

There are two possible ways to mount the atomic clock:

•use of the foldout table stands, or

•wall mounting

FOLDOUT TABLE STAND

The Foldout table stand legs are located on the backside, at the lower corners, and on both sides of the battery cover. The hinges are towards the edges of the atomic clock, and the ends (with no hinge) need to be folded out towards the edge. Once the Foldout table stands are extended, place the atomic clock in an appropriate location.

WALL MOUNTING

1)Using a straightedge, horizontally space at 2-3/4 of an inch (70 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

The outdoor temperature transmitter can be mounted in two ways:

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

La Crosse Technology Atomic Clock Wwvb Manual

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

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. Do not use solvents or scouring agents.

•Do not submerge the units into water.

•Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of the recommended size.

•Do not make any repairs to the units. Please return it to the original point of purchase. Opening and tampering with the units may invalidate the warranty.
