NOTES:
Every time the power adaptor unplugged and with no batteries inserted, the main unit will
lose all the weather data.
1) Mounting the outdoor sensor onto the stainless steel mast
Attention!! Before assembly the outdoor sensor, the transmission between main unit
and the thermo-hygro sensor must be established
For accurate results, the outdoor sensor mast should be securely mounted onto a horizontal
surface and in an open area away from trees and other coverings where rainfall or wind speed
may be reduced causing inaccurate reading.
The following diagram shows how the parts go together.
2) Mounting the wind speed sensor to the plastic bracket：first check the wind-fan
can rotate freely before fixing. The wind speed sensor should now be mounted onto the
bracket provided to allow the wind to travel around the sensor unhindered from all
directions.Then fix it with bolt and screw. Please follow the below display:
3) Mounting the wind direction sensor to the bracket: first check the wind direction
sensor before fixing, the wind direction sensor should now be mounted onto the bracket
provided to allow the wind to travel around the sensor unhindered from all directions.Then fix it
with bolt and screw. there is one cable from wind speed sensor, please insert it into the socket
under the wind direction sensor.please follow the below display:
Attention!! Please align the “North” indicator sticker with the NORTH direction to enable it to
record accurate reading
4) Mounting the rain sensor to the bracket: there are vertical engraved lines at the
bottom edge of the round cover and the sensor part, you only need adjust the two line into one
position, then turn clockwise, the rain sensor part will be connected well, then fix them with 4
screws and bolt onto the plastic bracket (don’t use only 2 screws) please follow the below
display：
Note: The cover of the Rain Gauge can be removed by rotating in an anti-clockwise
direction. When replacing the cover it will only fit in one position. When you find the
