6. Check the cable for correct connection and test all the components for correct functionality by manually turning the wind-gauge; tilting the optional rain sensor to hear the impact of the internal moving seesaw, etc. (See Positioning below).

7. Time and date must be manually set (See Manual Setting below).

8. After the Weather Center has been tested and found fit, the initial set up of the weather station system is finished and the mounting of the system components can take place. Ensure that all components work properly together at their chosen mounting or standing locations before permanent mounting.

For example, if there appears to be problems with the 915 MHz radio transmissions, they can often be overcome by slightly changing the mounting locations or turning the base station.

NOTE:

The radio communication between the receiver and the transmitters in the open field reaches distances of up to 330 feet/ 100 meters, provided there are no interfering obstacles such as buildings, trees, vehicles, high voltage lines, etc.

9. Radio interferences created by cordless phones, PC screens; radios or TV sets can in some cases entirely cut off radio communication. Please consider this when choosing standing or mounting locations.

NOTE:

 After batteries are installed in the transmitter, install the batteries in the weather center to receive the

signal from the transmitters as soon as possible. If the weather center is powered more than 5 hours after the transmitter is powered, the weather center will never receive signal successfully from the transmitters. In this case, you will need to reinstall the batteries from all the transmitters to redo set-up procedure.

 After batteries are installed, there will be synchronization between Weather Center and the

transmitters. At this time, the signal reception icon will be blinking. When the signal is successfully received by the Weather Center, the icon will be switched on (If it is not successful, the icon will not be shown).

 The short blinking of the icon shows that a reception is in progress.

Transmitter signal reception icon

 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-synchroni zation.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE THERMO-HY GRO TRANSMITTER

The outdoor Thermo-hygro transmitter works with 2 x AA IEC LR6, 1.5V batteries. To install and replace the batteries, please follow the steps below:

1. Remove the airflow cover of the transmitter.

2. Remove the battery compartment cover.

3. Insert the batteries, observing the correct polarity (see the marking in the battery compartment).

4. Replace the battery cover and the airflow cover onto the unit.

NOTE:

When changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because the thermo-hygro sensor at start-up assigns a random security code and this code must be received and stored by the Weather Center in the first several minutes of power being supplied to it.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO THE WEATHE R STATION

The Weather Station works with 2 x C, IEC LR14 1.5V batteries. When the batteries need to be replaced,

the low battery symbol will appear on the LCD. 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 the marking in the battery compartment).

3. Replace the battery cover.

HOW TO INSTALL AND REPLACE BATTERIES INTO THE RAIN SENSOR (OPTIONAL; SOLD SEPERATELY)

Figure 1

ure 2 Figure 3

1. Unlock the main cover from the rain sensor base and remove the cover.

2. Remove the battery cover at the top of the rain sensor.

3. Insert 2 x AAA IEC LR3 1.5V batteries into the battery compartment, observing the correct polarity.

4. Replace the battery cover and the main cover on the unit.

NOTE:

When changing batteries in any of the units, all units need to be reset by following the setting up procedures. This is because the transmitter and rain sensor (optional) assi gn a random security code at start-up and these codes must be received and stored by the Weather Station in the first 90 secon ds 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. (For battery life information, see the Specifications section)

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

- Do Not Mix Old and New Batteries

- Do Not Mix Alkaline, Standard, or Rechargeable Batteries

NOTE:

The stored History record is lost when a battery change is completed on the weather station.

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

NOTE:

 After battery change, both the Weather Station and the transmitters need to be reset (see note ”Set

up”)

 The History data record will be clear after the battery change.

OUTDOOR TRANSMITTER 915 MHz RECEPTION CHECK

The outdoor temperature, humidity, wind data are transmitted from thermo-hygro transmitter every 4.5 seconds; the rainfall data are transmitted from the rain sensor (optional) every 6.25 seconds. The receiver will synchronize to the thermo-hygro transmitter and rain sensor (optional) then. The transmission range (up to about 330 feet /100 meters in open air) of the thermo-hygro transmitter/ rain sensor may be affected by the ambient temperature. At cold temperatures, the transmitting distance may decrease. Please keep this in mind when placing the transmitter and the rain sensor.

If (1) the outdoor data is not being received within first several minutes after set up; (2) the outdoor display always shows “- - -“ on the outdoor display; or (3) the reception icon of thermo-hygro transmitter (Mode 1) and rain sensor (optional) (Mode 2) is not displayed on the display, check the follo wing things:

1. The distance of the Weather Station or transmitter/ rain sensor should be at least 5 to 6.5 feet (1.5 to 2 meters) away from any interfering sources such as computer monitors or TV sets.

2. Avoid positioning the Weather Center onto or in the immediate proximity of metal doors or window frames.

3. Using other electrical products such as headphones or speakers operating on the same signal frequency (915 MHz) may prevent correct signal transmission and reception.

4. Neighbors using electrical devices operating on the 915 MHz signal frequency can also cause interference.

NOTE: When the 915 MHz signal is received, do not re-open the battery compartment cover of the transmitter/ rain sensor or Weather station, as the batteries may spring free from the contacts and force a false reset. Should this happen accidentally then reset all units (see Set up above) otherwise transmission problems may occur. During normal operation, after the outdoor display shows "- - -", the weather station will change to receive the outdoor data every 15 minutes, until the data is read. Then the reception period for thermo-hygro transmitter will return to 4.5 seconds (6.25 seconds for rain sensor - optional).

If no reception is possible despite the observation of these factors, all system units have to be reset (see

Set up). POSITIONING:

Prior to permanently mounting any of the units, please ensure the following points are considered:

 Cable lengths of the units meet with your distance requirements at the point of fixing  Signals from the sensors can be received by the base station at points of mounting

La Crosse Technology Sensor Extension Cable

You can purchase a La Crosse Technology Extension Cable if you require additional length to properly mount your sensor. The extension cable is 32 feet in length and comes with the appropriate connecter

attached. Please visit your local retailer or www.lacrossetechnology.com and click on the Buy button to

locate an online dealer or other retailers. Using phone cables or connections may damage your sensors because phone cables and connections

have more resistance than the La Crosse Technology extension cable. Phone cables or connections are not recommended for use.

NOTE: Using extension cables will shorten battery life. Warning: Never cut, splice, shorten or modify your sensor cables or extension cables. Doing so may

damage your sensors and will void your warranty.

The Weather Station

The Weather Station is designed to be free standing only.

The Thermo-hygro Sensor

Rain Cove

Main Uni

Wall Bracket

An ideal mounting place for the thermo-hygro sensor would be the outer wall beneath the extension of a roof, as this will protect the sensor from direct sunlight and other extreme weather conditions. Be sure to mount vertically.

To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in the thermo-hygro sensor to the bracket and secure both parts by the use of the supplied screw and ensure that the cable from the wind sensor is correctly plugged in otherwise data transmission errors could occur.

The Wind Sensor

Vertical mast

Wind -cups

Horizontal panel

Check that the wind-cups can rotate freely before fixing the unit. For correct and accurate readings, it is important to mount the sensor with the cups on the bottom. The wind sensor should now be mounted using the screw or cable tie provided onto a solid wall/ panel mast or mast to allows the wind to travel around the sensor unhindered from all directions (ideal mast size should be from diameter 0.62” to 1.29” (16mm to 33mm). Do not over tighten the mounting bracket .

Once the wind sensor is fixed onto the mast, connect the cable to the corresponding thermo-hygro sensor socket so that operating power supply can be received and data can be transmitted to the base station. Secure cord from blowing. Do not use staples. Using PVC pipe or metal as a mast may cause static. Wood is recommended.

The Rain Sensor (optional)

Horizontal panel

For best results, the rain sensor should be securely mounted onto a horizontal surface about 39.37” (1 meter) above the ground (or higher) and in an open area away from trees or other covering s where rainfall may be reduced causing inaccurate readings.

When securing into place, check that rain excess will not collect and store at the base of the unit but can flow out between the base and the mounting surface (test by pouring clean water). Do not tighten scre ws past just snug.

After mounting the rain sensor and placing battery, the rain sensor is now operable. For testing purposes, very slowly pour a small amount of clean water into the rain sensor funnel. The water will act as rainfall and will be received and displayed at the base station i.e. when the reading interval is reached.

CARE AND MAINTENANCE:

 Do Not Mix Old and New Batteries  Do Not Mix Alkaline, Standard, or Rechargeable Batteries

 Extreme temperatures, vibration and shock should be avoided as these may cause damage to the

unit and give inaccurate forecasts and readings.

 Precautions shall be taken when handling the batteries. Injuries, burns, or property damage may be

resulted if the batteries are in contact with conducting materials, heat, corrosive materials or explosives. The batteries shall be taken out from the unit before the product is to be stored for a long period of time.

 Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new

batteries of the recommended type.

 When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or scourin g

agents as they may mark the LCD and casings.

 Do not submerge the unit in water.  Special care shall be taken when handling a damaged LCD display. The liquid crystals can be

harmful to user's health.

 Do not make any repair attempts to the unit. Return them to their original point of purchase for repair

by a qualified engineer. Opening and tampering with the unit may invalidate their guarantee.

 Never touch the exposed electronic circuitry of the device, as there is danger of electric shock, should

it become exposed.

 Do not expose the units to extreme and sudden temperature changes, this may lead to rapid changes

in forecasts and readings and thereby reduce their accuracy.
