Why does the “Check Antenna” message appear on the display of my Yamaha AV receiver?
• The XM Mini-Tuner and XM Dock are not connected to the XM jack of the unit. Power the receiver off and verify all connections. • The XM jack is not functioning and you will need to contact an authorized Yamaha service center for assistance. • The XM antenna is not functioning and you will need to contact Audiovox for assistance or if possible try plugging the XM antenna into another Yamaha receiver as a test to verify.
