Operating instructions

When using modern DSLR lenses that have no physical stop on the focus ring,
auto calibration cannot be used. These lenses must be calibrated manually using
the following steps.
BEFORE STARTING MANUAL CALIBRATION, ENSURE THAT THE MOTOR IS
NOT ENGAGED TO THE LENS GEAR. WHEN IN MANUAL CALIBRATION
MODE, THE MOTOR MOVES AT FULL SPEED AND TORQUE. PLEASE ENSURE
THAT YOU ARE HAPPY AND FAMILIAR WITH THE SPEED BEFORE ENGAGING
THE GEARS TO AVOID UNINTENTIONAL DAMAGE TO THE LENS.
To start manual calibration, press the inf.rot button on the receiver unit and the
indicator light will go red. The receiver and the hand unit will ash U.C for
uncalibrated, and the A and B soft stop buttons will ash, indicating that they
need to be set.
With the teeth away from the lens, turn the knob until it passes its centre point. At
this point, the motor and knob will sync and the knob will now control the motor
position.
The motor in this mode moves very fast and with high torque. Please turn the
knob and motor back and forth a bit to familiarise yourself with the speed and
response. Once you are happy, move the lens to the middle of its range of
rotation and mesh the motor and lens gears together.
Slowly and carefully move the knob towards the ashing A button (Anti
clockwise) until the lens is aligned on its stop. Press and hold the A button to
record the stop. Now move the knob the other way towards the B button
(Clockwise) until you are on the stop. Press and hold the B button to record this
stop.
