. Place the supplied U-shape metal plates around the mast. lnsert 4 pieces of the
supplied Hex screws through the holes of the U-shape plates and the holes on the
anemometer's mounting bracket. (The wind vane is above the wind cup and the
metal bar of the anemometer is in horizontal level).
. Tighten the supplied Hex nut onto both ends of each screw.
The best location for the anemometer is mounted on a mast in an open area where wind
is not blocked on top, sides, or above roof level on the building where the monitor is
located. Before mounting the anemometer, measure the distance between the monitor
& anemometer and be sure it is within the effective transmission range.
Select a mounting location for the anemometer that is:
. Outdoors, not blocked on top or sides, so wind can freely reach the anemometer.
. Within 50 meters (164 feet) open area from the monitor. Reduce dstance if
obstacles are between the anemometer & the monitor.
NOTE: lt is recommended to perform a simple RF transmission iest before mount ng.
2.3 Setup Procedure
. Place the anemometer horizontally in your selected outdoor location.
. Loosen the screws on the battery door with a small Phillips screwdriver and open the
battery door.
. Place the monitor in your selected indoor location and power with the ACIDC
adapter.
NOTE: Put 3 x AAA batteries into the monitor for back up purposes in case of a power
outage.
. Use the compass on the anemometer and turn the wind vane so it is pointing due
north.
. While holding the wind vane pointing due north, insert 2 AA batteries according
to the polarity indicated. The red LED indicator above the battery cover of the
anemometer will flash a few times right after battery installation. Be sure the wind
vane is pointing due north at the moment when red LED flashes, the calibration is
now completed. Replace the battery cover and tighten the screws.
. lf the wind vane is not pointing due north when the red LED first flashes, remove
batteries and repeat set up steps.
. Hold "CHANNEL/SEARCH' button on the monitor for 3 seconds and the wind
direction, temperature & humidity icons will flash on the display. The monitor is now
searching for all remote sensors.
. lf valid wind direction, wind speed and channel-1 temperature,/humidity readings are
shown on the monitor within 1 0 minutes, the RF transmission is successful and the
anemometer & monitor are within the effective transmission.
. lf above readings are not shown after 1 0 minutes of searching, the transmission has
failed.
. Shorten the distance between the anemometer & monitor. Reset
the anemometer by removing all batteries from the anemometer
& wait for 1 0 seconds before reinstalling the batteries again.
IMPORTANT: The same setup procedures are to be followed whenever battery
replacement is done.

2,4 Mounting and Set Up Procedure for the Rain Gauge
Before mounting the rain gauge, be sure the rain gauge & monitor are within the
transmission effective range and batteries are installed. select a mounting location for
the rain gauge that is a flat, level surface and look for a location where the rain gauge
can be placed 1 meter or more above ground level. For the wireless feature the rain
gauge needs to be within 30 meters (1 00 feet) in an open area away from the monitor'
Reduce distance if there are obstacles between the rain gauge & the monitor' Finally
make sure that the rain gauge is in an area that is not blocked on the top or sides. This
is so rain can freely reach the rain gauge (for example, not under an overhang or too
close to a building or fence).
2.5 Mounting Procedure
. Hold the base of the rain gauge flat against the mounting surface then use a level to
make sure the rain gauge (as it rests on the mounting surface) is horizontally level'
. Use a pencil to trace the inside of the mounting holes on the base of the rain gauge
to mark the screw locations.
. Drill a hole in the center of each marked location and insert the supplied plastic screw
plugs.
. Hold the rain gauge against the mounting surface so the holes on the base are
aligned with the plugs, then thread the supplied washer head screws into each hole
and use a screwdriver to tighten them.
Caution:
. To prevent false rainfall readings caused by water splashes, do not choose a location
that is not level or that is too close to the ground, a swimming pool, lawn sprinklers,
or anywhere water might accumulate or run off.
. The screen in the cylinder of the rain gauge filters most debris (such as leaves) that
might fall into the rain gauge. To avoid frequent build-up of debris in the cylinder, do
not mount the rain gauge too close to trees or plants.
. During cold months it is recommended to bring the rain gauge indoors Snow or rain
may freeze in the rain gauge and damage it.
2.6 Setup Procedure
. Press the tabs back as indicated below to unlock the rain gauge cover.
. Lift the rain gauge cover off its base. Then carefully remove the packing tape from
the bucket assembly.
. Open battery cover and insert 2 pieces of AA batteries according to the polarity
indicated. Close the battery cover.
. Replace & lock the rain gauge cover on the base.
. Hold "CHANNEL/SEARCH" button on the monitor for 3 seconds and the total rainfall
"- - - -" will flash. The monitor is now searching for all remote sensors.
. Total rainfall reading (in this case "0" mm or inch) will appear within 2 minutes if
the RF transmission is successful and the monitor & rain gauge are now within the
effective transmission range.
. lf total rainfall "- - - -" stops flashing and stays on the display after 2 minutes of
searching, the RF transmission has failed. Shorten the distance between the monitor
& rain gauge. Reset the rain gauge by removing all batteries from the rain gauge
and wait for 1 0 seconds before re-installing the batteries again. Then repeat steps
above.
Connecting Remote Sensors
The weather station uses 433MHz radio signals to send and receive weather data
between the monitors and remote sensors.
After battery installation, the monitor will automatically search for remote sensors.
You can also enforce a searching mode by holding "CHANNEL/SEARCH,, on the monitor.
Follow the instructions in the "Set Up Procedure" section to set up the sensors and
wireless connection- lf the connection cannot be established, reset the remote sensor
by removing the batteries from the sensor. Wait for l0 seconds and reinstall the
batteries. Then hold 'CHANNEL/SEARCH" on the monitor to search for the sensors. lf
that continues to fail, shorten the distance between the sensor & monitor and reinstall
the sensors if necessary (Details refer to the "Set Up procedure" section).
3.0 Weather Forecast & Barometric Pressure
