Position the main unit, rain gauge, and thermo sensor
within effective range:
•Rain gauge - 100 meters / 328 feet
•Thermo sensor - 100 meters / 328 feet
IMPORTANT It is recommended that you follow the
sequence below when setting up the units:
1. Set up the main unit.
2. Set up the rain gauge, then press and hold SEARCH
on the main unit and wait until you receive a
signal.
3.
Set up the thermo sensor, then press and hold SEARCH
on the main unit and wait until you receive a
signal.
4. In the event that you do not obtain a signal from a
remote unit please repeat the process above.
MAIN UNIT
1. Insert the batteries, matching the polarity (+ and -)
as shown in the battery compartment.

2. Press RESET, or press and hold SEARCH on the
main unit to initiate operation. The reception icon
on the main unit will blink while it is searching for
the sensor or rainfall gauge.
NOTEEvery time the battery in the main unit is changed,
repeat installation before use.
RAIN GAUGE
The rain gauge collects rain and takes readings of rainfall
rate and the total rainfall over a period of time. The
sensor can remotely transmit data to the base station.
The base station and rain gauge should be positioned
within an effective range: about 100 meters (328 feet)
in an open area.
The rain gauge should be mounted horizontally about 1
meter (3 feet) from the ground in an open area away from
trees or other obstructions to allow rain to fall naturally
for an accurate reading.
To set up the Rain Gauge:

Water will pool to the center of the cross when the rain
gauge is level.
If water remains on 1-4, the gauge is not horizontal.
If necessary, adjust the level using the screw.
NOTE For best results, ensure the base is horizontal to
allow maximum drainage of any collected rain.E
THERMO SENSOR
1. Insert the batteries, matching the polarity (+ and -)
as shown in the battery compartment.
1. Remove screws and slide the cover off in an
upwards motion.
2. Insert the batteries (2 x UM-3 / AA), matching the
polarities (+ / -). Press RESET after each battery
change.
3. Remove the bre tape.
To ensure a level plane:
Put a few drops of water on the cross at the base of the
funnel to check the horizontal level.

2. Set the channel switch to any channel. The switch
is located in the battery compartment.
3. Press RESET on the sensor.
4. Close the remote sensor battery compartment.
5. Secure the sensor in the desired location using the
wall mount or table stand.
For best results:
•Insert the batteries before you mount the sensor.
•Place the sensor out of direct sunlight and
moisture.
•Do not place the sensor more than 100 meters
(328 feet) from the main (indoor) unit.
•Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.
•Place the sensor in a location with a clear view to
the sky, away from metallic or electronic objects.
•Position the sensor close to the main unit during
cold winter months as below-freezing temperatures
may affect battery performance and signal
transmission.
You may need to experiment with various locations to
get the best results.
Standard Alkaline batteries contain signicant amounts
of water. Because of this they will freeze in low
temperatures of approximately -12°C (10°F). Disposable
Lithium batteries have a much lower threshold for
temperature with an estimated freezing range of below
-40°C (-40°F).
Wireless ranges can be impacted by a variety of factors
such as extremely cold temperatures. Extreme cold
may temporarily reduce the effective range between the
sensor and the base station. If the unit’s performance
fails due to low temperature, the unit will resume proper
functioning as the temperature rises to within the normal
temperature range (i.e. no permanent damage will occur
to the unit due to low temperatures).
DATA TRANSMISSION
Data is sent from the remote thermo sensor approx.
every 78 seconds and every 94 seconds from the
rain gauge. The reception icon shows the status - see
table.

Searching
Connected
Disconnected
If without obvious reason the main unit display
shows that the thermo sensor or rainfall connector is
disconnected, press and hold SEARCH to enforce an
immediate search.
If that fails, check:
•The remote rain gauge and thermo sensor are still
in place.
•The batteries of the main unit, rain gauge, and
thermo sensor are still good. Replace them if
necessary.
•The transmission is within range and path is clear of
obstacles and interference. Shorten the distance if
necessary. Then press and hold SEARCH again.
LOW BATTERY WARNING
There are 3 low-battery indicators - see table.

operating in an unfavorable way. Use a blunt stylus
to hold down the button. All settings will return to their
default values.
PRECAUTIONS
This product is engineered to give you years of
satisfactory service if you handle it carefully. Here are
a few precautions:
Use HISTORY to display the record for a particular
