WIRELESS SIGNAL RECEPTION
Weak signalStrong signalSignal searching Signal lostNo sensor
The wireless sensor is capable of transmitting data wirelessly over an approximate operating
distance of 150m range (line of sight).
Occasionally, due to intermittent physical obstruction or other environment interference, the signal
may be weaken or lost.
In the case that the sensor signal is lost completely, you will need to relocate the display main unit
or the wireless sensor closer to each other.
DATA CLEARING
During installation of the wireless sensor, the sensor was likely to be triggered, resulting in
erroneous rainfall measurements. After the installation, user may clear out all the erroneous data
from the Display Main Unit, without needing to reset the clock and re-establish pairing.
1. Press and hold [ HISTORY ] button for 3 seconds.
2. Press [ UP ] or [ DOWN ] button to choose “YES” or “NO”.
3. Press [HISTORY] button to conrm. This will clear out any rainfall data recorded before.
MAINTENANCE OF RAIN GAUGE
1. Rotate the rain collector in anticlockwise direction.
2. Gently remove the rain collector.
3. Clean and remove any debris or insects.
