3.6.1.3 Auto-On
The Auto-On input allows to define how the transponder will behave
when power is supplied to it.
If the aircraft is equipped with a dedicated avionics master switch that
switches the power supply to the transponder, the pin "Auto-On" must be
wired together with the UB+ pin to the avionic master switch. The on/off
button on the transponder is without function in that case. The
transponder will start automatically whenever power is supplied.
On aircraft without such an avionics master switch, the pin "Auto-On"
must be left unconnected. In this case, the transponder must be switched
on and off via the transponder's on/off button on the front panel.
3.6.2 Static Air Port
Install a silicon soft tube fitting the 5 mm static air hose at the backside of
the transponder and secure plumbing with appropriate clamps.
