Turn the platter back over and place it on the spindle.

Spin the platter 2 times clockwise to unloop the band from the raised prong on the platter and to loop it around the raised prong on the turntable base. This allows the circular motion of the motor to spin the band and the turntable platter.

You may replace the round clip at this point though it is not important to the sound quality of the turntable.
