Torque Adjustment Instructions
Higher torque levels should be used for rough-running lenses.
Note: Take care to re-calibrate the CLM-3 motor after re-attachment
of the motor and after each lens change!
Ignoring this procedure can lead to severe lens damage.
Lower torque levels should be used for smooth-running lenses.
Note: If the torque level is not adequate to lens properties or
operation temperature, the electronic torque limitation may
cause a high-frequency noise.
Use a higher torque level to reduce this effect.
