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.

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.

AA"UM3 1.5V

"AA" U M 3 1. 5 V

RGR126(R13)-4(final) 4/6/05, 5:46 PM6

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.

RGR126(R13)-4(final) 4/6/05, 5:46 PM7

•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.

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 .
