user to carry out an instant check on the quality of the radio communications.
The signal strength is indicated by the LED.
It may light up green, yellow or red according to the quality of the radio signal
received.
Green: The signal received is good or excellent, radio communication is reliable.
Yellow: The signal received is sufficient.
Red: The signal received is weak, communication is not reliable.
The status of the output of the actuator that is currently switched off is
signalled with the corresponding LED faintly lit rather than off, so that the
quality of the radio signal can always be seen.
The receiver indicates two types of signal quality via the LED:
- An immediate analysis of the last command received;
- A long-term analysis of the commands received.
The LED will normally indicate the "long-term" signal quality, based on the quantity
of correct commands received over the previous 90 minutes of operation.
At the moment when it receives a radio command, the output LED goes off for
a brief instant and then immediately back on again. For a brief instant the LED
will provide an immediate indication of the last command received, proportional
to the strength of the radio signal received.
If a transmitter is in the "test" mode, the LED on the receiver will always provide
only an "immediate" indication so that you can instantly assess whether to go
ahead with mechanical installation.
If the signal strength is not acceptable, try changing the position of the receiver
or, if necessary, of the transmitter.
