7. CAMERA REMOTE
The operation of zoom operation and record start/stop can be remotely controlled by connecting a remote controller
with ZOOM S/S remote jack.
The operation of focus and iris operation can be remotely controlled by connecting a remote controller with
FOCUS/IRIS remote jack.
NOTE: CAMERA remote control is only effective in the CAMERA mode.

7-1-1. Record start / stop input
Every time A terminal connects with the GND, it repeats recording and a recording stop.
7-1-2. Zooming control input
With the voltage to input to the B terminal, the zoom speed changes. As for the relation between the zoom control
voltage and the zoom speed, it is as shown in the following.
Relation between the zoom control voltage and zoom speed
voltage and the zoom speed, it is as shown in the following.

7-2-2. IRIS control input
When terminal D is open, the VCR becomes AUTO-IRIS mode. When terminal D connects with the GND, the VCR
becomes MANUAL-IRIS mode.
With the voltage to input to the C terminal, the iris is changes. As for the relation between the iris control voltage
and the iris, it is as shown in the following.
Even if AUTO-IRIS is used, the iris can be corrected according to the input voltage.
Relation between the iris control voltage and iris
becomes MANUAL-IRIS mode.
With the voltage to input to the C terminal, the iris is changes. As for the relation between the iris control voltage
and the iris, it is as shown in the following.
Even if AUTO-IRIS is used, the iris can be corrected according to the input voltage.

8. CAUTION WHEN INSTALLING AUDIO CONTROL KNOB
The AUDIO VR is weak against stress. So when the AUDIO Control Knob is removed from the AUDIO VR, it is very
possible that AUDIO VR is broken. Please replace the AUDIO VR by a new one, when you have removed the
AUDIO Control Knob from the AUDIO VR. When installing the AUDIO Control Knob, set its direction as follows.
(Installation of AUDIO Control Knob)
1. Set the AUDIO VR to fully counter-clockwise as shown in figure A.
2. Install the AUDIO Control Knob to AUDIO VR as follows.
