TTG (Trough The Glass) version (L5 option)

The 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 pickups 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 became usable.
