920.1.2 SWITCHING ON THE UNIT (PRE-FLIGHT CHECK)
1 Check that the circuit breaker is set and switch on the aircraft power supply .
Do not switch on the transponder if the motors or engines are being started or shut down.
2 Using mode selector (A), switch the transponder from OFF to SBY. A test then follows
automatically for 1 seconds. The display shows 'WAIT' and the unit is subject to a self-test
simultaneously.
3 After the switch-on test has elapsed and no error-message is written in the display, the
transponder switches to the mode set on the mode selector (A).
