Automatic Audio Muting - Garmin G1000 Pilot's Manual

ADDITIONAL FEATURES

AUTOMATIC AUDIO MUTING

XM Radio audio is muted automatically when the aircraft groundspeed exceeds approximately 30 knots and
the airspeed is less than approximately 80 knots. The audio will not be un-muted automatically. The audio
must be manually un-muted once the aircraft is airborne and outside the applicable speed range. Automatic
Audio Muting has been implemented to meet regulatory requirements that the aural stall warning be heard.
When the aircraft is operating within the auto-mute airspeed range, the MUTE Softkey and the Un-mute
selection of the Page Menu are unavailable, appearing in half-tone text, preventing the audio from being
un-muted at this time.
Audio availability conforms to the following three states:
• Audio is available on the ground until the aircraft exceeds 30 knots
• Audio is automatically muted (not available) from Airborne Status up to 80 knots airspeed
• Audio is available when airspeed is over 80 knots
Un-muting XM audio:
1) With the XM Radio Page displayed, press the VOL Softkey.
2) Press the MUTE Softkey to restore (un-mute) XM Audio.
