QUICK SET-UP GUIDE

Hint: Use good quality Alkaline Batteries and avoid rechargeable batteries.

1.Have the Wireless Weather Station and remote thermo/hygro sensor 3 to 5 feet apart.

2.Batteries should be out of both units for 10 minutes.

3.Place the batteries into the remote thermo/hygro sensor first then into the Wireless Weather Station.

(All remote thermo/hygro sensors must be started before the Wireless Weather Station)

4.DO NOT PRESS ANY BUTTONS FOR 15 MINUTES.

In this time the Wireless Weather Station and remote thermo/hygro sensor will start to talk to each other and the display will show both the indoor temperature/humidity and an outdoor temperature/humidity. If the Wireless Weather Station does not display both temperatures after the 15 minutes please retry the set up as stated above. After both indoor and outdoor temperatures and humidity are displayed for 15 minutes you can place your remote thermo/hygro sensor outdoor and set your time.

The remote thermo-hygro sensor should be placed in a dry, shaded area. The thermo-hygro sensor has a range of 330 feet. Keep in mind that the 330 feet is in open air with no obstructions and that radio waves DO NOT curve around objects. Actual transmission range will vary depending on what is in the path of the signal. Each obstruction (roof, walls, floors, ceilings, thick trees, etc.) will effectively cut signal range in half.

Example: A Wireless Weather Station with a 330 feet range is mounted on an interior wall, so that the signal has to pass through one interior wall, one exterior wall, and across the 10 feet width of the room between the 2 walls. The first wall will reduce the range to 165 feet, and the second wall will reduce the range to 87 feet. Factoring in the 10 foot room, this leaves a maximum of 77 feet of remaining signal range.

This allowance is typically enough for a frame wall with non-metallic siding; however certain materials can reduce range even further. Metal siding, stucco, and some types of glass can reduce signal range by as much as 3/4 or more, compared to the 1/2 reduction typical of most obstructions. It is possible to receive a signal through these materials, however maximum range will be much less due to their tendency to absorb or reflect a much larger portion of the sensor’s signal.

DETAILED SET-UP GUIDE

Battery Installation

I. BATTERY INSTALLATION (When on thermo/hygro sensor is being used)

1.First, insert the batteries to the thermo/hygro sensor (see “A. Remote Thermo/hygro Sensor” below).

2.Within 2 minutes of powering up the sensor, insert the batteries to the Weather Station (see “B. Wireless Weather Station” below). Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and humidity, and the time as 12:00 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. 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 sensor. The outdoor temperature and humidity should then be 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 and the signal reception icon is no longer shown.

A. Remote Thermo/Hygro Sensor

1.Remove the mounting bracket. The bracket snaps on and off easily.

2.Remove the battery cover, by sliding the cover down.

3.Observing the correct polarity install 2 AA batteries. The batteries will fit tightly (to avoid start-up problems make sure they do not spring free).

ABOUT WWVB (radio-controlled time)

The NIST (National Institute of Standards and Technology-Time and Frequency Division) 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 indoor weather station. However, due to the nature of the Earth’s Ionosphere, reception is very limited during daylight hours. The Wireless Weather Stations 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 measure 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. For more information about WWVB please see the NIST website at http://www.boulder.nist.gov/timefreq/stations/ wwvb.htm

B. Wireless Weather Station

1.Remove the battery cover (the cover has white writing on it).

2.Observe the correct polarity, and install three Alkaline AA batteries.

3.Do not press any buttons for at least ten minutes. If a button is pressed before the indoor weather station has received information from the TX29UD-TH sensor, no data will be received from that sensor until reset.

4.Replace the battery cover.

*When the signal is successfully received by the Weather Station, the icon will be switched on. (If not successful, the icon will not be shown in LCD) So the user can easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is being done now.

•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 another 45 seconds. If still not successful the reception is tried for 45 seconds on 910MHz. This will also be done for re-synchronization.

II. Start Up Sequence

A. Initial Start

1.Immediately after the batteries have been installed, the Wireless Weather Station will sound a “beep”, and the LCD will completely light up for a brief moment.

2.All information will then appear in normal mode, with “12:00” as the default time and “SA.1” as the default date (2006 as the year).

3.The indoor temperature and humidity, and barometric air pressure (as 29.92 inHg) will also be displayed.

4.There is a “satellite” icon that appears in the bottom portion of the LCD, between the outdoor temperature and humidity - this icon informs the user that the indoor weather station is looking for signals from the remote thermo/hygro sensor. Within five minutes the remote temperature and humidity should be displayed-if not, remove batteries from all units and repeat battery installation, the remote thermo/hygro sensor first, then the Wireless Weather Station.

B. WWVB Reception

1.Once the batteries are installed in the Weather Station, it will automatically search for the WWVB signal. If it receives a good signal (which is unlikely during daylight hours in most locations), the WWVB reception indicator (looks like a tower icon) will flash. The Wireless Weather Station requires five full minutes of good reception to successfully capture the signal and set to the correct hour, minute, second, month, day and year. If the signal reception is not successful within ten minutes, the signal search will be cancelled. Next reception will take place the next day.

2.The signal is sent from Ft. Collins, Colorado only and is similar to an AM radio signal. Atmospheric interferences such as storms, sunspots, and even sunlight will cause the signal to not travel as far.

3.To maximize reception, place the Wireless Weather Station in a window facing Colorado, at least six feet from any electrical source (computers, televisions, refrigerators, etc.). Do not move the Wireless Weather Station while it is searching for the signal.

4.The time and date can be manually set. Once the signal is captured, it will override any time and date set to the time zone selected.

5.Once the time and date are set, the indoor weather station will conduct a search every night between midnight and 6:00 a.m and correct to the accurate time and date (Daylight Saving Time is automatic). If the signal has been received in the past 24 hours, the reception indicator will be displayed. After a successful reception, no more reception attempt would be made until the following day.

3.A “sad-face” will be displayed when the temperature and humidity are outside the mentioned ranges.

F. Weather Forecast Icon and Pressure Trend Indicators

The weather forecasting feature is estimated to be 75% accurate, and is based solely upon the change of air pressure over time. The WS-8035U-IT averages past air-pressure readings to provide an accurate forecast-creating a necessity to disregard all weather forecasting for 12-24 hours after the unit has been set-up, reset, or moved from one altitude to another (i.e. from one floor of a building to another floor). In areas where the weather is not affected by the change of air pressure, this feature will be less accurate.

1. Weather Icons

a.There are 3 possible weather icons that will be displayed at various times in the center of the Wireless Weather Station

iSunny-indicates that the weather is expected to improve (not that the weather will be sunny).

iiSun with Clouds-indicates that the weather is expected to be fair (not that the weather will be sunny with clouds).

iiiClouds with Rain-indicates that the weather is expected to get worse (not that the weather will be rainy).

b.The weather icons change when the unit detects a change in air pressure.

c.The icons change in order, from “sunny” to “sun with clouds” to “clouds with rain” or the reverse.

d.It will not change from “sunny” directly to “clouds with rain”, although it is possible for the change to

2.The “0h” represents the current full hour air pressure recording.

3.The columns represent the “hPa” (0,±2, ±4, ±6) at specific time.

4.The “0” in the middle of this scale is equal to the current pressure and each change±(2, ±4, ±6) represents how high or low in “hPa” the past pressure was compared to the current pressure.

5.If the bars are rising it means that the weather is getting better due to the increase of air pressure.

6.If the bars go down, it means the air pressure has dropped and the weather is expected to get worse from the present time “0h”.

Note: For accurate barometric pressure trends, the Weather Station should operate at the same altitude for example, it should not be moved from the ground to the second floor of the house. Should the unit be moved to a new location, discard readings for the next 12-24 hours.

This feature cannot be turned off.

VII. MOUNTING

Note: Before permanently mounting, ensure that the Wireless Weather Station is able to receive signals from the transmitters and WWVB signal at the desired location. To achieve a true temperature reading, avoid mounting the remote thermo/hygro sensor (or any sensor) where direct sunlight can reach the remote sensor. We recommend that you mount the remote sensor on a North-facing wall or under an eve. The sending range of the remote thermo/hygro sensor is 330-ft (100m) however obstacles such as walls, concrete, and large metal objects can reduce the range. Place all units in their desired location, and wait approximately 15 minutes before permanently mounting to ensure that there is proper reception. If the indoor weather station loses the signal from the remote sensor, it will display the last temperature reading for 15 minutes. After 15 minutes of not receiving any signals, the remote temperature will display “- -.-”.

B. Mounting the WS-8035U-IT Wireless Weather Station

The Wireless Weather Station can be mounted in two ways; free standing or hanging on a wall.

To have the Wireless Weather Station free standing, simply unfold the stands on the back and set on a stable flat surface.

To wall mount the Wireless Weather Station;

1.Ensure that the integrated stands are folded in.

2.Fix a screw (not included) into the desired wall, leaving approximately 3/16 of an inch (5mm) extended from the wall.

3.Place the indoor weather station onto the screw using the hanging hole on the backside.

4.Gently pull the Wireless Weather Station down to lock the screw into place.

Maintenance and Care Instructions

A.Extreme temperatures, vibration, and shock should be avoided to prevent damage to the units.

B.Clean displays and units with a soft, damp cloth. Do not use solvents or scouring agents; they may mark the displays and casings.

C.Do not submerge in water.

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

E.Opening the casings invalidates the warranty. Do not try to repair the unit. Contact La Crosse Technology for repairs.

TROUBLESHOOTING

Problem: The LCD is faint.

Solution:

1.Set the LCD contrast to a higher level.

2.Replace batteries.

Problem: No outdoor temperature/humidity is displayed.

Solution:

1.Remove all batteries, reinsert into the remote thermo/hygro sensor first, then into the indoor weather station.

2.Place remote thermo/hygro sensor closer to the Wireless Weather Station.

3.Be sure all batteries are fresh.

4.No other interfering sources are being used (such as computer monitors, TV sets, headphones, or speakers) in the vicinity. The signal travels in a straight line, an electrical source near that “line” may cause interference.

A. Mounting the Remote Thermo/hygro Sensor

The remote thermo/hygro sensor can be mounted with the use of screws or by using the adhesive tape.

A. MOUNTING WITH SCREWS

1.Remove the mounting bracket from the remote thermo/hygro sensor.

2.Place the mounting bracket over the desired location.

3.Through the three screw holes of the bracket, mark the mounting surface with a pencil.

4.Screw mounting bracket onto the mounting surface. Ensure that the screws are flush with the bracket.

5.Insert the remote thermo/hygro sensor into the bracket.

B. 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.

3.Adhere the tape to the designated area on the back of the mounting bracket.

4.Remove the protective strip from the other side of the tape.

5.Position the remote thermo/hygro sensor in the desired location, ensuring that the Wireless Weather Station can receive the signal.

Note: Mounting with adhesive tape is not recommended as a permanent mounting solution. Only use the adhesive tape during set-up process.

P.15 GB

Problem: Temperature, humidity, or air pressure is incorrect.

Solution:

1.Check/Replace batteries.

2.If multiple remote sensors are in use, check location with corresponding “boxed numbers.”

3.Move away from sources of heat/cold.

4.Adjust relative air pressure to a value from a reliable source (TV radio, etc.).

5.The Wireless Weather Station and remote sensors are calibrated at the factory. If there is a consistent problem, please call La Crosse Technology.

Problem: “- -” or “99%”in humidity display.

Solution:

1. Humidity is below 1% or above 99%.

Problem: WWVB time and date will not set or update

Solution:

1.Wait until overnight for signal to be received

2.Move Wireless Weather Station away from sources of electricity

3.Place Wireless Weather Station in window facing Colorado

4.The first reception is most difficult, as the indoor weather station needs five continual minutes of clear signal reception. After the initial time/date set, the indoor weather station only requires one full minute of clear reception each night.
