"EXT (MOD AM)"
Selects the external source. The external signal is added to the inter-
nal signal. Switching off the internal source is not possible. The exter-
nal signal is input via the Ext connector. The sensitivity is 10 mV per
percent modulation depth.
Note: There can be an overmodulation as a function of the level of
the external signal without a corresponding caution message being
generated. To avoid an overmodulation, the peak value of the exter-
nal signal is to be delimited corresponding to the sum of the modula-
tion depths of the remaining VOR signal components.
