Insert 2xLR6 (AA size) batteries into the transmitter, the LED located in the back of raincollector will be
turned on for 4 seconds, then it will be off and start to work normally. The transmitter will make a data
transmission and then start radio controlled time reception routine. If time signal can be detected
correctly, the LED will start to flash 5 times, and then the LED will be on for 20s,
indicating time signal
has been found correctly. When time signal is bad and reception is not possible, the transmitter will
terminate radio controlled time reception within one minute and resume normal mode. When there is a
data transmission happened, the LED will be on for 20ms. During radio controlled time reception period,
there is no transmission and normal transmission will only resume after time reception routine is
complete. The longest time for radio controlled time reception is 5 minutes.
Receiver /Indoor unit
After inserting the batteries into the Weather Station, all LCD segments will be turned on for a few
seconds, all possible display segments are turned on for checking.
After this, the weather station will make initial measurement and start to register the transmitter (the
radio reception icon will be turned on). Do not press any key before outdoor sensor data received,
otherwise the outdoor sensor learning mode will be terminated. When outdoor transmitter has been
registered, the base station will automatically switch to the normal display mode from which all further
settings can be performed by the user.
If no RCC signal is detected in the initial setup, the transmitter will try once every two hours to get an
RCC signal until a signal is received. Once the transmitter receives the RCC signal it will transmit the
signal to the monitor. On the monitor the RCC tower icon will be displayed, if the monitor doesn’t receive
the RCC signal or loses the signal continuously for 12 hours the RCC icon will not be display.
Note for RCC signal:
The best condition for reception is at night, between midnight and 6:00am – when there is less
atmospheric interference.
Note:
If a battery change on the transmitter side happened, the receiver will be resynchronized to the
transmitter again within the next 3 hours. If you want to shorten the receiving data time, the base station
has to re-install the battery so that it can have the new security code learnt right way, but the previous
weather data and alarm value settings in receiver will be lost.
Note:
Commonly the radio communication between receiver and transmitter in the open field can reach a
