Remove the turntable from the bottom road case and place in final operational position. Recommended 
installation requires a surface capable of supporting up to 60Kg (120 lbs) and a 480mm (19”) wide x 480mm 
(19”) deep surface which allows space for the power cable to exit neatly.

Please note the 4 x LONG M6 transport securing screws used to lock the table chassis to the suspension 
system (vibration isolation platform) during shipping. They are located near the inner edge of the Platter Ring 
shown below. 

Once the turntable is in its final operating position, remove the 4 x LONG M6 transport securing screws with 
an Allen wrench (Hex key).
