TRANSMITTER BOX-BATTERY INSTALLATION

The solar panel on transmitter box is an energy saving feature, which is an environmentally friendly way to provide power to the sensors and prolongs battery life. It can entirely provide power to the supplied rechargeable battery. Sensors can operate entirely on the rechargeable battery power. Locate the transmitter box under direct sunlight for power supplying by the solar panel.

The rechargeable battery from factory is not with full battery for long time use and it probably becomes low battery during the shipping. We recommend you to charge it for several hours by the connected solar panel.

You can also purchase a power adapter separately for directly providing power to the transmitter box. The output voltage of the power adapter is 3V. Route the adapter cable through the cable slot.

Please check the solar panel connection. If it is not firmly plugged, please re-connect the solar panel:

Plug the end of color-cored connector into corresponding socket in the transmitter box as shown below and place the wires neatly inside the box.

To install the rechargeable battery:

Insert the battery into the battery compartment, matching the polarity +1 .

CHANNEL SETTING

Your weather station system can expand with up to 8 sets of thermometer & humidity sensors, and one of each of wind and rain sensors, which share one main unit to display the weather readings. You can number each transmitter box with an independent channel ID (1-8) by sliding the switches.

Please follow the below chart to adjust the sliding switches of SW1:

NOTE The below 0 in the chart represents off and 1 represents on.

CH PIN 2 PIN 3 PIN 4

WIND

DIRECTION CALIBRATION

Before pairing a wind sensor, make sure the head of the wind vane of that sensor point to the north while pressing KEY for 2 seconds in the transmitter box to calibrate the direction. If the calibration is successful, red light flashes once. You can use a compass to look for an accurate direction of north if necessary.

However, if you are the user in North America, there are already 15^ (degree) variations existing between the true north and a compass reading of north. You can consult your local observatory about this issue.

If it is difficult to control the wind vane after installation, you can calibrate through setting on main unit.

1. Make a compass approach to the wind vane.
2. Calculate the angle between the current direction and the north direction.
3. Press wind area to activate.
4. Press and hold SET, and then press or to calibrate the angle value.
5. Press SET again to confirm setting.

For example, inputting the angle value that you want to set as north. If current direction is 25 degree and you want to set it as north, then you input 25 degree in the calibration mode. Once you return to the idol mode, the direction reading displays 0 degree, which is the north.

NOTE You need to calibrate the wind sensor again if you want to relocate the sensor.

MAINTAINANCE

Each sensor of this kit has a durable plastic casing that should retain its luster for many years. It is better to do regular maintenance to keep the sensors with high accuracy every half year. Do cleaning the casing only with a soft cloth slightly dampened with water or a mild soap. Please use screw drivers or wrench to take some parts off if necessary.

Electrical storms can sometimes cause power surges harmful to electronic equipment. For your own safety, take caution when using the main unit or doing maintenance during storms.

TO MAINTAIN THE THERMO/HYGRO SENSOR

1. Remove the rain collector from the rain gauge.
2. Unscrew the three type B screws from the rain gauge
3. Unscrew the three screws from the bottom of the thermo/hygro sensor casing.
4. Clean the casing excluding the one with sensor by water, and then remove the dust around the sensor carefully.
5. Install all the parts until they are entirely dried.

NOTE If the temperature and humidity readings are

still strange and inaccurate, you need to consider replacing this sensor, please contacting our customer service for the details.
