Volume
Radio volume is shown as a percentage. Volume level is
controlled by pressing the VOL Softkey, which brings up
the MUTE Softkey and the volume increase and decrease
softkeys.
Adjusting the volume:
1) With the XM Radio Page displayed, press the VOL
Softkey.
2) Press the VOL – Softkey to reduce volume or press
the VOL + Softkey to increase volume. (Once the
VOL Softkey is pressed, the volume can also be
adjusted using the small FMS Knob.)
3) Press the MUTE Softkey to mute the audio. Press
the MUTE Softkey again to unmute the audio.

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 is not unmuted automatically. The audio must be
manually unmuted 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 automute
airspeed range, the MUTE Softkey and the volume
softkeys are subdued, and the Unmute selection of the
Page Menu is unavailable, preventing the audio from being
unmuted at this time.

Softkey.

Audio.
11.7 SCHEDULER
The Scheduler feature can be used to enter and display
reminder messages (e.g., Change oil, Switch fuel tanks,
or Altimeter-Transponder Check) in the Alerts Window
on the PFD. Messages can be set to display based on a
specific date and time (event), once the message timer
reaches zero (one-time; default setting), or recurrently
whenever the message timer reaches zero (periodic).
Message timers set to periodic alerting automatically reset
to the original timer value once the message is displayed.
When power is cycled, all messages are retained until
deleted, and message timer countdown is resumed.
