Features: variable-speed rocker zoom control; manual focus
control; record start/stop (R); LED indicator, iris (F- / F+)
1. Plug the controller into the
“Remote” jack specified in your JVC
owner’s manual. DO NOT PLUG THE CONTROLLER INTO
ANY OTHER JACK OR DAMAGE MAY RESULT.
2. You can attach the controller to your tripod handle, monopod,
shoulder support, or stabilizer with the adjustable clamp (do not
overtighten)
. The controller doesn’t require any external power
or setup. Once connected, the controller is ready to perform.
3. The rocker switch at the bottom is for zooming. Since it is a variable rocker, the farther you
press it right the faster it will zoom in (telephoto), and the farther you press it left the faster it
will zoom out (wide).
4. The small button marked with
a red “R” is the record start/stop button.
5. You can also control the focus of your lens manually using the controller. You must first set
the camera to “Manual Focus” mode (consult JVC manual if necessary). Once you are in
Manual Focus mode, you can use
the switch on the controller marked “FOCUS” to precisely
adjust the focal plane. Pressing the up arrow (
) will move the focal plane farther away while
pressing the down arrow (
) will bring the focal plane closer. Note: the available focal
range will be somewhat reduced at telephoto.
6. Control the iris setting with the F- and F+
buttons. You must first set the camera to “Manual
Iris” mode (consult JVC manual if necessary). F- will lower the f-stop (open iris) while F+ will
raise the f-stop (close iris) between 1.8 and 8.0 (range will differ at telephoto).
6. Finally, the LED indicator light will turn on and off to indicate recording status. When you
start recording the LED will turn red, and when you stop it will turn off. There is a very slight
delay from the time you hit record to the time the LED illuminates. There is a slightly longer
delay from the time you stop recording to the time the LED turns off
– this is normal.
Troubleshooting: 1) Zoom Creeping (unwanted zooming): Recalibrating the zoom center is easy. With the
controller connected to your camera, loosen the brass set screw on the underside of the
rocker with a 5/64” hex key
(allen wrench), holding the rocker firmly in place. On the backside of the rocker is a hole with a slotted shaft, and
thi
s is where you adjust the zoom center with a flat screwdriver. Turn it slightly left and right and you’ll see the
camera zoom in and out
– find the centermost point between the zoom in/out start positions, then tighten the brass
set screw (don’t overcrank it). 2) Controller not responding: Unplug the unit and plug it back in after a few
seconds.
