Radio COM 1 and COM 2
The COM 1 and 2 are located on the upper part of the radio block, just below the annunciators.
Figure 8.40: COM 1 and 2
Both radios are identical and operated the same way:
In order to change the COM frequency, you first need to select the COM you want to use 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 set the stand-by frequency by means of the double encoder FREQ. The small rotary
switch sets the digits after the decimal point (0.25 MHz increment). The large button sets the
digits before the decimal point.
Finally you put the stand-by frequency to in-use by pushing the button ACTIVATE.
The frequency displayed on the upper part of the digital display is in use, the frequency displayed
on the lower part is on stand by.
