ETS-Lindgren 2181 Turntable - Manual (Page 30)

30 | Operation
Do not operate the turntable in a stalled condition. Doing so may
cause damage to the drive unit and will void your warranty.
Always make sure that the minimum speed setting specified in
the S1-S8 parameters is above the minimum value at which your
turntable will rotate under normal load.
Speed Selection
For the variable speed turntable, the Polarization/Flotation button provides the
ability to cycle between eight preset speeds. For each press of the button, the
turntable will change to the next speed setting. The polarization LEDs will light to
indicate the speed selection as shown in the following:
Speed 1: Both off
Speed 2: Top on, bottom off
Speed 3: Top off, bottom on
Speed 4: Both on
Speed 5: Both off
Speed 6: Top on, bottom off
Speed 7: Top off, bottom on
Speed 8: Both on
Each speed setting has an individual overshoot compensation value to provide
overshoot correction.
