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. If
your focus ring moves forward when you turn it, position the gear so that it is near the front of the ridges on the focus ring. If
your lens has internal focus (i.e., the focus ring does not move forward), you can position the gear in the in the middle of the
focus ring. 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).
If the motor does not turn the focus ring all the way, you can extend the range (this will be necessary to get full range on the
EX-1 and EX-3). The VZ-EFC has a default range of 1300, but the range may be extended to 1740 or 1900. Press and hold
the SCROLL button while powering the unit. The display will show RANGE and either 1300 (default), 1740, or 1900. Use the
SCROLL button to select the desired range and press the SELECT button to save.
The direction of movement for the motor can also be changed if desired. “REVERSED” is the default setting, and it is the
setting that will work with the previously mentioned setup instructions for the motor bracket. If you want to switch the motor
direction, take that into account when setting the up the motor bracket. To change the direction: Press and hold the SELECT
button while powering the unit. The display will show SIGNAL and either “Reversed” or “Normal”. Use the SCROLL button to
select the signal direction and press the SELECT button to save. The “signal” and “range” configurations are saved in
memory so you do not have to set them each time you power the VZ-EFC.
The EFC’s default configuration is for “Reversed” signal direction and a range of 1300. To reset these defaults, press and
hold the SELECT and SCROLL buttons while powering the unit. The display will show “Defaults Loaded” and then start
normal operation.
PROGRAMMING FUNCTION
You can program up to 4 sequential focal marks. To program your marks, hit the SCROLL button until you are in ‘Mark’
mode, and then hit the SELECT button. You will see “A” come up, then 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. To mark “B”, hit SCROLL, adjust to the desired
position, and hit SELECT. However, you only need to program the number of marks you desire. For example, if you only
want to mark “A”, program it and hit SCROLL until you reach “EXIT”, then hit SELECT (in this case, only mark “A” will show in
the MAIN display mode).
The marks are saved in memory and do not have to be programmed again each time the EFC is powered. 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). To erase a specific mark, you must SCROLL to ‘Mark’ mode,
go to the mark in question, turn the control knob to 0000 (fully counter-clockwise), and press the SELECT button.
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. Although the
battery should last for many hours on a full charge, for extra runtime, note that an additional VZ-B72 battery can be
purchased and attached to the bottom of the battery on the unit (‘double-stacked’ so that you can plug into the extra
battery when the first runs out).
