Dynon Avionics EFIS-D10A Installation Guide - Manual (Page 63)

Autopilot Installation and Configuration
STEP 6 - AUDIO ALERTS CONFIGURATION
This section applies only if you have installed the optional AP74.
The optional AP74 can act as the sole audio alert source for all DSAB-connected Dynon
instruments. The audio output of the AP74 reports both EFIS and EMS alerts; each type of alert
can be configured to be either voice or tone formats. When the AP74 is connected to your
system, audible alerts are still generated by both EMS- and EFIS-based instruments. If you
would like the AP74’s audio out to be your only source for Dynon product audible alerts,
disconnect the audio out connections on your other DSAB-connected Dynon products.
The AP74 and HS34 have identical voice output capabilities. If an HS34 Voice/Tone
output is already connected to the aircraft intercom, do not connect the AP74 Voice/Tone
output. If the Voice/Tone output of both an HS34 and an AP74 are connected in parallel,
audio alerts will be distorted.
To configure AP74 audio alerts, enter the EFIS > SETUP > AP menu, scroll down to AUDIO
ALERTS, and press SEL►. The following
points describe the options available for
each setting:
