6. If an XM Satellite Radio subscription has already been activated for the GDL 69A
SXM, then start the system and select the XM Information Display and make sure
the GDL 69A SXM is working properly. Especially check for the presence of
weather products and radio signal strengths.
7. After ensuring all GDL 69A SXM interfaces to external equipment are working
correctly, a brief EMI/RMI check must be conducted. This check will verify the
GDL 69A SXM does not produce unacceptable interference in other avionics
systems.
a) Open the circuit breaker for the GDL 69A SXM.
b) Start the aircraft engine(s) and switch to aircraft power.
c) Turn on all avionics except the GDL 69A SXM.
d) With the GDL 69A SXM circuit breaker open, make sure all existing avionics
systems are functioning properly.
e) Close the GDL 69A SXM circuit breaker.
f) Make sure all existing avionics systems continue to function properly.
7.8.1 Audio Entertainment Testing
Entertainment audio muting occurs when aircraft radio or marker beacon activity is
heard. Audio is always soft muted when an interruption occurs from these sources. Soft
muting is the gradual return of audio to its original volume level. The time required for the
volume to return to normal is between one-half and four seconds.
Pressing and holding the MKR/MUTE Key for three seconds switches muting of crew
entertainment audio on and off. When switching, either one or two beeps are heard; one
beep indicates that audio muting is enabled, two beeps indicate audio muting is disabled.
Entertainment audio muting is independent for each audio panel. Pressing the MKR/
MUTE Key on one audio panel does not enable or disable entertainment audio muting on
the opposite side. Entertainment audio muting is reset (enabled) when started.
Passenger entertainment audio is never muted.
This section verifies correct installation in the aircraft. It does not activate
the GDL 69 XM data link radio. If the XM Radio is activated, the channel list
will contain more channels than the three that are shown for a radio that
has not been activated. Complete instructions for activating the XM data
link can be found in Garmin document 190-00355-04 or by calling XM at 1-
800-985-9200. XM service is currently only available in the U.S. and select
Canadian areas. See www.siriusxm.com for coverage areas.
