TTG technology allows the user to operate on the keypad of
the HMI without the need of opening the windowed cover of
the transmitter. The capacitive pick-ups will detect the
presence of your finger in front of the respective button
activating the specific command. At the transmitter power-on
the HMI automatically calibrate its sensitivity, it is mandatory for
the proper functioning of the TTG HMI that the cover is properly
tightened at power-on.
In case the cover has been removed to access the
communication board, it is recommended to power off and
power-on again the transmitter once the windowed cover has
been set in place and properly tightened. For safety reasons
the keypad needs a specific activation procedure before to
become usable
