2. Selecting a location for the anemometer
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 meter (164 feet) open area from the monitor. Reduce distance if obstacles is between the
anemometer & the monitor
The best location for the anemometer is usually mounted on a mast in an open area where wind is not blocked on
top or sides, or above roof level on the building where the monitor is located.
Testing the effective transmission range
Before mounting the anemometer, measure the distance between the monitor & anemometer and be sure it is
within the effective transmission range. It is recommended to perform a simple RF transmission test before
mounting.
1) Place the monitor in your selected indoor location and install adapter & batteries (see “Battery & adapter
installation for the monitor” section above)
2) 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. Insert 2 pieces of AA batteries according to
the polarity indicated. Close the battery door and tighten the screws.
3) 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.
4) If valid wind direction, wind speed and channel-1 temperature/humidity readings are shown on the monitor
within 10 minutes, the RF transmission is successful and the anemometer & monitor are within the effective
transmission.
If above readings are not shown after 10 minutes of searching, the transmission is failed.
Shorten the distance between the anemometer & monitor. Reset the anemometer by removing all batteries
from the anemometer & wait for 10 seconds before re-installing the batteries again. Repeat step 3 & 4 until
the transmission is successful.
5) Remove all batteries from the anemometer before mounting and calibration.
NOTE: Whenever the radio-controlled icon is flashing on the display, the weather station is receiving
radio-controlled clock signal and the RF reception for remote sensors will stop temporary for around 8 minutes.
Wait until this icon stops flashing (or disappear) before searching for the remote sensors.
3. Mounting the anemometer
Important: Before mounting, be sure the monitor & anemometer are within the effective transmission range.
Note: To mount the anemometer, you need a mast (not supplied) about 1 – 1.25 inches (2.54 – 3.1 cm) in
diameter, and the hardware necessary to fasten it to the mounting location. If you previously installed such a mast
(for mounting antenna, for example), you can mount the anemometer on that mast.
1. If necessary, mount and ground a mast as directed in the instructions provided by the mast.
2. Place the supplied U-shape metal plates around the mast. Insert 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)
3. Tighten the supplied Hex nut onto both ends of each screw

4. Calibrating the anemometer & installing batteries
After mounting the anemometer, follow these steps to calibrate the wind direction so that the anemometer
properly measures the wind direction and transmit to the monitor. Be sure battery has been removed from the
anemometer before the calibration.
Important: The same calibration (step 1 to 5) is needed for the first set up and every battery replacement.
1. After mounting the anemometer, loosen the screws on the battery door with a small screwdriver and open
the battery door.
2. Use the compass on the anemometer and turn the wind vane so it is pointing due north.
3. Hold the wind vane pointing due north and do not allow it to turn. Insert 2 pieces of AA batteries according
to the polarity indicated. The red LED indicator above the battery cover of the anemometer will flash few times
right after battery installation. Be sure the vane is pointing due north at the moment when red LED flashes
and the calibration is now completed. Replace the battery cover and tighten the screws.
4. If the wind vane is not pointing due north when the red LED first flashes, remove batteries and repeat step
2 & 3.
5. Hold “CHANNEL/SEARCH” buttons on the monitor to search for remote transmitter. Wind direction, wind
speed, wind chill & channel-1 temperature/humidity readings will appear within 10 minutes if the RF
transmission is successful.

5. Selecting a location for the rain gauge
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.
- within 30 meter (100 feet) open area from the monitor. Reduce distance if obstacles is between the rain
gauge & the monitor
- in an area not blocked on the top or sides, so rain can freely reach the rain gauge (for example, not under
an overhang or too close to a building or fence)
Cautions:
- 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 the
trees or plants
6. Battery Installation for the rain gauge
1. Press the tabs back as indicated below to unlock the rain gauge cover
2. Lift the rain gauge cover off its base. Then carefully remove the packing tape from the bucket assembly
3. Open battery cover and insert 2 pieces of AA batteries according to the polarity indicated. Close the battery
cover
4. Replace & lock the rain gauge cover on the base
5. 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) will appear within
2 minutes if the RF transmission is successful and the monitor & rain gauge are now within the effective
transmission range.
6. If total rainfall “- - - - “ stop flashing and stay on the display after 2 minutes of searching, the RF
transmission is failed. Shorten the distance between the monitor & rain gauge. Reset the rain gauge by
removing all batteries from the rain gauge and wait for 10 seconds before re-installing the batteries again.
Then repeat step 5 (& 6) until the RF communication is completed.
NOTE: Whenever the radio-controlled icon is flashing on the display, the weather station is receiving
radio-controlled clock signal and the RF reception for remote sensors will stop temporary for around 8 minutes.
Wait until this icon stops flashing (or disappear) before searching for the remote sensors.
7. Mounting the rain gauge
Before mounting the rain gauge, be sure the rain gauge & monitor are within the transmission effective range and
batteries are installed.
1. Hold the base of the rain gauge flat against the mounting surface then use a level to make sure the rain
gauge (as it rest on the mounting surface) is horizontally level.
2. Use a pencil to trace the inside of the mounting holes on the base of the rain gauge to mark the screw
locations.

3. Drill a hole in the center of each marked location and insert the supplied plastic screw plugs
4. 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.
8. Installing additional remote thermo-hygrometer sensor(s)
Additional remote thermo-hygrometer sensors can be purchased separately (not supplied in the package).
1. Select a location for the remote thermo-hygrometer that is within the effective transmission range of 100
meters (328 feet). Shorten the distance if obstacle is between the monitor & remote sensor.
2. Use a small screwdriver to loosen the screws on the battery door of the remote sensor. Insert 2 pieces of
AAA batteries according to the polarity indicated.
3. Assign channel 2 or 3 to the remote sensor by setting the slide switch inside the battery compartment.
(Channel 1 is used by the anemometer and should not be assigned to the new remote thermo-hygrometer)
4. Press “Tx” button inside the battery compartment of the remote sensor to transmit temperature & humidity
data to the monitor. Then close the battery door and tighten the screws.
5. Hold “CHANNEL/SEARCH” button on the monitor to search for all remote sensors. The temperature &

21/ BATTERY DISPOSAL & PRECAUTIONS ON THE USE OF BATTERIES
- Replace only with the same or equivalent type recommended by the manufacturer.
- Discard a used battery in nature or garbage pollutes and prevents the recovery of recyclable materials.
It is therefore important to limit consumption of batteries and follow these guidelines:
focus on alkaline batteries (that last longer than the saline batteries) and when possible, rechargeable
batteries
deposit batteries and accumulators in specific containers arranged among traders.
For example, metals will be valued and polluted the environment because they contain heavy metals hazardous
to health and the environment primarily (cadmium and nickel)
- The piles must installation by respecting the polarity indicated on the apparatus and the pile.
An incorrect positioning can is to damage the apparatus, is to cause escapes on the level of the pile, is to the
extreme to cause a fire or the explosion of the pile.
- To ensure proper operation, the batteries must be in good condition. In case of abnormality in the functioning of
the device, put fresh batteries
- Never attempt to recharge non-rechargeable batteries. They could run, warm up, causing a fire or explosion.
- Replace all batteries at the same time.

Never mix zinc batteries with alkaline batteries or rechargeable batteries
- The batteries must be removed from the device
- Also, remove the batteries from your device if you do not use it for a long time, if the batteries may leak and
cause damage.
- Never try to short-circuit the battery terminals
- Never dispose of batteries in fire, they might explode
- Charging of batteries is to be performed by an adult.
- Remove batteries from the device before reloading.
- We recommend an adult to supervise children when they change the batteries so that these instructions are
complied with or to make himself the replacement of batteries.
- If a battery is swallowed, immediately consult a doctor or poison control center nearest you. Do not forget to
carry the product with you.

IMPORTANT NOTE:
Warning! The weather station and the outside sensor contain sensitive electronic components. Radio waves
transmitted e.g. from mobile telephones talkies -walkies, radios, WiFi, remote controls or microwaves may
influence the transmission distance of the weather station and the outside sensor and lead to a shorter reception
range. It is therefore important to keep as great distance as possible between the devices of the weather station
and the outside sensor and the devices which send out radio waves. We do not guarantee the maximum
specified transmission range between the weather station and the outside sensors due to the radio frequency
interference in the environment.
