-== General Inspection ==
+== Listening Test ==
-Check for signs of wear and tear, scratches or dents in the Cylindrical Radiator®s, the Power Stand, and {{B1}} or {{B2}} bass modules.
+Listen to the system running full-range pre-recorded music at full stage volume.
+== Cylindrical Radiator® ==
+=== Physical Inspection ===
+[[File:L1Disassembled.gif|right]] Check the Cylindrical Radiator® sections under good light for dents and scratches. These won't affect the operation of the unit, but it's good to find these now instead of under stage lights later.
+Check the ends of the Cylindrical Radiator® sections.
+When the system is fully assembled, look at it from the side to make sure the Cylindrical Radiator® stands straight. If it doesn't then it's likely the bayonet is bent.
+=== Drivers ===
+There are 24 drivers in the {{Model II}} Cylindrical Radiator® (12 in the {{Model 1S}}).
+Play some music and listen carefully for sound from all drivers. Listen for rattles and buzzes.

+=== Cases and Bags ===
+Check the cases and bags for damage or wear and tear.
+== Power Stand Firmware ==
+If the system comes with a {{B2}} and the Bass Level Switch works in all three positions, you have the latest firmware. If the system comes with a B1 or the B2 Bass Level Switch does not work, check the firmware.

+== Bass Module ==

 If the system has a {{B2}}
 check that the B2 Bass Level switch works in all three positions. If it does, then the L1 Model II Power Stand firmware is up to date.
