Audible and Visible Alerts
Voice and tones are used to alert the pilot. The alert
descriptions used by TCAD are listed in the TCAD Pilot’s
Handbook. Voice is used only during the highest level
of alerting; otherwise, tone is used. The voice alerting
can be turned on or off from the TCAD Setup Page or
from the configuration pages. See the Garmin 400/500
Series Installation Manual available at authorized Garmin
Service Centers (only for the 9900 model).
Fault Displays
If the unit fails to detect the TCAD or if the TCAD data
that is received is invalid, the traffic screen shows “DATA
FAIL”.
Limitations
Refer to the TCAD Pilot’s Handbook for limitations of
the TCAD system.
