Annex-B-17
The SEL-CAL tones can be sent by pressing the [Send Tones] key. While the tones are
being sent Modulation ENABLED is replaced by the message *** SENDING TONES *** and the
normal modulation tone is suppressed.
The SEL-CAL code can be modified by pressing the [SEL-CAL Code] key to produce a
display similar to the one shown in Fig. B-19. Operation of this facility is identical to that of the
Sequential Calling Tones Utility in non-avionics mode. The tone duration and gap can be set but
the default values are those usually used for SEL-CAL. Alternative standards can be selected
using the [Select Standard] key. The [Mode Control] key can be used to change the mode from
single shot but the default setting in always single shot.
