First, determine which gear you need to use and attach it to the motor. The Canon gear is marked “C” and the Fujinon is
marked “F”. For the SonyEX series of cameras, you will use the “F” gear. 1) Remove the screw in the center of the motor
spindle. 2) Install the appropriate gear. 3) Replace the screw in the motor spindle.
Un-screw (A) the Focus ring gear and then placing it around the focus ring on the camera, then re-attach the screw and

CONNECTION AND MANUAL OPERATION
Leave the drive gear disengaged from the focus ring. Connect the EFC control unit to the motor using the supplied extension
cables, and turn on the power by pressing the POWER button. The EFC control unit has three display modes: ‘Volt’, ‘Mark’,
and ‘Main’. The EFC must be set to ‘Main’ for operation. ‘Main’ is the default mode when you turn on the power. Pushing the
SCROLL button cycles you through the three modes, but you want to be in ‘Main’ mode at this point.
Set the lens to “infinity” and turn the dial on the control unit so that the LCD reads “0” before you engage the gear. You will
notice that the individual arms of the motor bracket assembly can be positioned by loosening the plastic tee-head screws.
Position the gear so that it is near the front of the ridges on the focus ring (or you can position it in the in the middle of the
focus ring if your lens has internal focus / “Innerfocus”). Once the gear has been mated to the focus ring, you can turn the dial
on the control unit to adjust the lens through the focal range (1300 to 0 on the LCD readout).
PROGRAMMING FUNCTION
You can program up to 4 sequential focal stop points. To program your stop points, hit the SCROLL button until you are in
‘Mark’ mode, and then hit the SELECT button. You will see “A” come up, and you should turn the dial until you reach the
desired focal point that you want to mark as “A”. Hit the SELECT button to set the focal point. Hit the scroll button to get to
“B”, turn the dial to the desired focal point you wish to mark as “B”, then hit SELECT. Repeat the same process for additional
marks. If you only wish to mark 2 focal points, then after marking “B” hit SCROLL until you reach “EXIT” and push SELECT.
Once you hit “EXIT”, the control unit is back in operating mode. Hit the SELECT button to shuttle between the marks in
sequence. Hit the SCROLL button once to go back to full range mode (manual), and hit it 3 times to go back through the
menu to reset your marks.
BATTERY CHARGING
You can check remaining capacity of the battery by pushing the button next to the row of indicator LEDs. To charge the
battery, first unplug the cable leading from the EFC control unit housing. Next, plug the supplied AC adapter into the
“Charging Interface Cable” and then plug it into the battery. When the battery is fully charged, the indicator light on the
charging interface cable will turn green. A full charging usually takes a few hours. Note that the row of indicator lights on the
battery does not accurately reflect remaining capacity while the charger is attached. The indicator lights only function
normally when the charger is disconnected. You should use the indicator light on the charging interface cable to determine
when the battery is fully charged (green light). NOTE: Do not attempt to remove battery from main unit.
NOTES
You should turn off the control unit when not in use. Do not expose the motor or control unit to water or excessive heat.
