Voice Call Out Selection - Garmin GTN 725 Pilot's Manual

11.4.14 Voice Call Out Selection

The Voice Call Out (VCO) selection is available when HTAWS is installed. The
VCO functionality provides a voice annunciation of the aircraft' s height above
terrain or the nearest airport, heliport, runway, or helipad when that threshold
is first crossed. The available call outs include "Five Hundred" through "One
Hundred" in one hundred foot intervals. The voice call outs can be enabled and
disabled through the Voice Call Outs Selection option on the System - Audio
page.
NOTE: VCOs are available down to 100 feet above terrain when HTAWS is
installed and use GSL above terrain to generate callouts (no radar altimeter
required). If a radar altimeter is interfaced to the GTN, alerts are available
down to 50 feet and the height above terrain when the radar altimeter is
used to generate the callouts.
To select the Voice Call Out choices in the System - Audio page, select the
Voice Call Out Selection item and then select the desired value.
1. From the Main page, touch System and then Audio.
2. Touch the Voice Callouts key to view the Voice Callouts page.
