GETTING STARTED
Position the main unit, rain gauge, and thermo sensor
within effective range:
•Rain gauge - 328 feet / 100 meters
•Thermo sensor - 98 feet / 30 meters
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.
NOTE Every time the battery in the main unit is
changed, repeat installation before use.
RAIN GAUGE (PCR122)
1. Insert the batteries, matching the polarity (+ and -)
as shown in the battery compartment.
2. Mount the rain gauge on a level surface.

5. Remove the fiber tape from around the bucket
assemblies.
THERMO SENSOR (THN122N)
1. Insert the batteries, matching the polarity (+ and -)
as shown in the battery compartment.
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.
3. Put drops of water on the cross at the base to check
the leveling.
4. Use the metal ring to adjust the level of the rain
gauge.

•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 significant amounts
of water. Because of this they will freeze in low
temperatures of approximately 10°F (-12°C). Disposable
Lithium batteries have a much lower threshold for
temperature with an estimated freezing range of below
-40°F (-40°C).
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).
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 98 feet (30
meters) from the main (indoor) unit.
•Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.

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.
THERMO SENSOR RAIN GAUGE DESCRIPTION
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.N
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.
UNIT LOCATION ON MAIN UNIT DISPLAY
Main Indoor Temperature Area
Remote Thermo Sensor Outdoor Temperature Area
Rain Gauge Total Rainfall Area
Replace the batteries immediately when the respective
indicator lights up.
CLOCK / CALENDAR SETTING
Press TIME / SET to toggle among today's rainfall, time,
date, and year.
SET CLOCK & CALENDAR
1. Press TIME / SET to display the clock or calendar.
2. Press and hold TIME / SET for two seconds.
3. Use or to set the desired value.
4. Press TIME / SET to confirm.
5. Repeat steps 3 and 4 to complete all settings.
6. The order of the settings is hour, minute, year,
month and day.

RAINFALL
Today's rainfall appears on the 1st line of the display
and total rainfall is shown on the 2nd line. Press in /
mm to toggle between inches and millimeters as the
unit of measurement.
RAINFALL HISTORY
The rainfall history is displayed on the 1st line of the
LCD display. The main unit can record up to 9 days of
rainfall.
Use HISTORY to display the record for a particular day.
The day of the record will be displayed with a minus (-)
sign.
Caution: Other sensors using the 433 MHz transmission
frequency may influence the rainfall reading. Please
avoid placing those sensors too close to the unit.
TOTAL RAINFALL
The total rainfall is displayed on the 2nd line of the LCD
display.
To display the commencing date of the total rainfall
record, press SINCE. The date will appear on the 1st
line of the display. Press again to show the commencing
year.
To clear the existing commencing date and reset it to
start again, press and hold SINCE. The total rainfall will
now be equal to the today rainfall and the unit will start
again to collect the rainfall data.
RAINFALL ALARM
The rain alarm value can be displayed at any time by
pressing (( • )).
To set the rainfall alarm,
1. Press and hold (( • )) for two seconds.
2. Use or to set the desired value.
3. Press (( • )) to confirm. The alarm will be activated.
The rain alarm indicator will light up.
The alarm will go off for one minute when the rainfall
reaches the preset value and the rain alarm indicator
will flash. A reminder beep will be emitted every minute.
Once the rain alarm is on the indicator will not stop
flashing unless is pressed or the rain alarm value is
changed. To stop the alarm and reminder beep, press
any button or change the rainfall alarm value.
To deactivate the alarm, press .
