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. 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 is not being received within first several minutes after setting 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
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 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 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.
