LOW BATTERY INDICATOR
The low battery indicator of the weather station and the transmitter will be displayed at the
second section, and the low battery icon for the rain sensor (optional) will be display on the
last section of the LCD respectively when the battery power is low. 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 ”Setting 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 be synchronized to the thermo-hygro
transmitter and rain sensor (optional) then. The transmission range (supposedly up to
about 330 feet /100 meters) of the thermo-hygro transmitter/ rain sensor may be affected
by the ambient temperature. At cold temperatures, the transmitting distance may be
decreased. Please keep this in mind when placing the transmitter and the rain sensor.
If (1) the outdoor data are not being received within first several minutes after setting up;
(2) the outdoor display always show “- - -“ 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, user shall check the following points:
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.
5. “Visibility” of weather center and transmitters increases the range
30
Note:
When the 915 MHz signal is received, do not re-open the battery compartment cover of
either 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 Setting 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 Setting up).
POSITIONING:
Prior to permanently affixing 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 phone 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 has been designed to be hung onto wall or free standing with the two
kinds of foldout stand.

To wall mount
Choose a sheltered place. Avoid direct rain and sunshine.
Before wall mounting, please check that the outdoor temperature
and humidity values can be received from the desired locations. To
wall mount:
1. Fix a screw (not supplied) into the desired wall, leaving the
head extended out the by about 5mm.
2. Hang the station onto the screw. Remember to ensure that it
locks into place before releasing.
The Thermo-hygro 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.
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 cables from the wind and rain sensors are correctly plugged in
otherwise data transmission errors could occur.

The Wind Sensor
Firstly, check that the wind-cups can rotate freely before fixing the unit. For correct and
accurate readings, it is important to mount the sensor so that the front (marked E) is
pointing in East-West direction. The wind sensor should now be mounted using the screw
or cable tie provided onto a solid wall/ panel mast or mast to allow 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.
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.
