Troubleshooting
Some quick troubleshooting steps listed below can be performed to find the
possible cause of a failure.
• Ensure the owner/operator of the aircraft in which the Data Link Receiver is
installed has subscribed to XM
• Ensure the
XM subscription has been activated
• Perform a quick check of the circuit breakers to ensure that power is applied
to the Data Link Receiver
For troubleshooting purposes, check the Menu on the Music Page or the
GDL 69 Box on the System - External LRUs Page for Data Link Receiver
(GDL 69/69A) status, serial number, and software version number.
It may take several minutes for all subscribed data to become available after
