Transponder
The transponder is located in the radio block between the NAV2 and the DME.
Figure 8.35: Transponder
In order to set the squawk code, you first need to select the XPDR as your active radio (surrounded
by the bright yellow rectangle). You do this by means of the frequency SELECT button (to
the right of the radios). If you turn the button clockwise, the radios will be activated in the
following sequence: COM1, NAV1, NAV2, XPDR, DME, ADF, COM2. If you turn the button
anti-clockwise, the yellow rectangle jumps counter-clockwise as well.

Then you put the transponder on stand-by (by means of the XPDR switch right of the transponder)
and set the squawk code by means of the double encoder FREQ. The small rotary switch changes
the two right-hand digits, the large switch the two left-hand digits. Turning the knobs clockwise
increments the numbers, turning the knobs anticlockwise decreases them.
