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.

LOW BATTERY INDICATOR
The low battery indicator of the weather station and the transmitter will be displayed in the second section,
and the low battery icon for the rain sensor (optional) will be shown 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 ”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 following 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
