GDL 69/69A DATA LINK RECEIVER TROUBLESHOOTING
Although it is the responsibility of the facility that installed the Data Link Receiver to correct any hardware
problems, some quick troubleshooting steps 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 LRU Information Box on the AUX - System Status Page for Data Link
Receiver (GDL 69/69A) status, serial number, and software version number.
