Next, insert the batteries into the Thermo-hygro sensor and Rain sensor (optional purchased separately) See “How to install and replace the batteries into the Thermo-hygro sensor“ and “How to install and replace the batteries into the Rain sensor (optional)” below. Then insert the batteries into the Weather Center (See “How to install and replace the batteries into the Weather Center” below).
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.
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.

change of icon if the weather gets any better (with sunny icon) or worse (with rainy icon) since the icons are already at their extremes. The icons displayed forecasts the weather in terms of getting better or worse and not necessarily sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon is displayed, it does not mean that the product is faulty because it is not raining.
NOTE: Once the weather tendency indicator has registered a change in air pressure, it will remain permanently visualized on the LCD. AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC PRESSURE TREND) The bottom section of the LCD also shows the relative air pressure value and the air pressure history. The bar graph of the electronic barometer shows the air pressure history of the past 12 hours in five 3-hour steps.
the ground to the second floor of the house, the readings for the next 48-60 hours shall be discarded.. WIND SPEED MEASUREMENT In normal display mode, the second section of the LCD shows the following wind data.
VIEW THE HISTORY DATA The weather station can store up to 140 sets of weather data which are recorded automatically at 3-hour intervals after the weather station is powered up, at the nearest time of 0:00, 03:00, 06:00, 09:00, 12:00, 15:00, 18:00 and 21:00. For instance, if user has manually set the time as 14:52 after installing batteries, the first history record will be made at the coming 15:00 automatically. Then the second record will be on 18:00 and so on.
HISTORY icon 3. When viewing History records, press MIN/ MAX to view older records. (Press MIN/MAX and + key to view "Previous" and "Next" record respectively. The records are made at 3-hour intervals) NOTE: The stored history records will not be retained after battery change or whenever battery is removed. • The total rainfall value will be exhibited in whole number (no decimal place) in the history record.

Press MIN/MAX key to show the desired weather data.
The total rainfall value is counted from this time and date Total rainfall icon Total rainfall amount To reset the rainfall reading: Press the + key once when the Rainfall value and Reset icon are shown. Then the total rainfall amount will be reset to 0, and the time updated to current time. NOTE: After power up, the time and date and total rainfall are displayed as "- - -". After time is adjusted manually, the set time will be shown.
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 be synchronized 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.
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.
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.
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 coverings 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 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.
