Power supply
Using the Anton/Bauer battery packA battery pack or an AC power source can be used as
this unit’s power supply.
To use the battery pack, there is a choice of three
makes of batteries, namely: 
OPanasonic
OAnton/Bauer
OSony

Batteries of other makes can also be supported by
changing the setting menu but no guarantees are
made for the system when they are actually used with
this unit.
Before using the battery pack, recharge the battery
using the battery charger.
(For details on the recharging method, refer to the
operating instructions of the battery concerned.)

An intelligent battery system and ultra light system are
supported.
The remaining battery charge displayed inside the
viewfinder is usually shown as a percentage of the full
charge, but when the battery charge is nearly
completely dissipated, the percentage display is
replaced with a voltage display.
1Attach the battery pack.
Insert the pack in the direction shown by the
arrows, and then slide it into position.
2To detach the battery, pull the battery mount
removal lever all the way down, and slide the
battery pack in the direction shown by the arrow.

Using an AC power supply
When the AJ-B75 AC adapter is used

OCheck the pin signals of the EXT DC IN socket
when using an external power supply other than the
AJ-B75 AC adapter. (DC 12 V, 8.5 A)
OPower from the AC adapter takes precedence when
both a battery pack and AC adapter have been
connected.
OWhen using the AC adapter, be absolutely sure to
first set the power of the AC adapter to ON and
then set the unit’s power switch to ON.
If the power is turned on in the reverse sequence,
the output voltage of the AC adapter will rise
gradually, and the unit may malfunction as a result.

4Push the cable into the cable clamp, and connect it
to the LENS socket.

OFor details on handling the lens, refer to the
operating instructions which accompany the lens.
OThe following lens adjustments and camera
adjustments may be necessary depending on the
lens mounted.
1. Lens flange back adjustment
2. Lens auto iris operating speed adjustment
3. Lens white shading adjustment (performed on
the unit)

Adjusting the lens flange
If the subject is not focused properly in the telephoto
and wide-angle modes during zoom operations, adjust
the flange back (distance from the lens mounting
surface to the image-forming surface).
Once this adjustment is done, it need not be redone
unless the lens is replaced.
Adjustment method
1Attach the lens to the camera.
At this stage, do not forget to connect the lens
cable.
2Set the lens aperture to manual and open the
aperture.
3Set the lighting in such a way that the appropriate
video output level is achieved at a distance of
about 3 meters away from the chart used for the
flange back adjustment.
If the video level is too high, use the filters and
shutter.
4Loosen the screw securing the F.f (flange focus)
ring.

On some lenses, this may be marked as F.b
(flange back) ring.
5Set the zoom ring to the telephoto position either
manually or electrically.
6Shoot the chart used for the flange back
adjustment, and turn the distance ring to adjust the
focus.
7Set the zoom ring to the wide-angle position, and
turn the F.f ring to adjust the focus.
Take care not to move the distance ring during this
process.
9Tighten the screw securing the F.f ring.
8Repeat steps 5to 7until the focus is adjusted at
both the telephoto and wide-angle positions. 
For details on the adjustment method and lens
positions, refer also to the operating instructions that
accompany the lens.

Adjusting the white shading
Follow the procedure outlined below when the white
shading needs to be re-adjusted.
Adjustment method

OThe method below can be used for the white
shading adjustments with most lenses.  However,
with some very special lenses, a different
adjustment method may be necessary.
OEven when the white shading has been adjusted,
tinting may occur in the vertical direction near the
lens aperture open position.  This is a phenomenon
which is inherent to lenses and optical systems and
is not indicative of malfunctioning.
SHUTTER: OFFGAIN: L (0 dB)JOG dial buttonMENU button
1Attach the lens to the camera.
At this stage, do not forget to connect the lens
cable.
2Set the electronic shutter to OFF, and set the gain
to “L (0 dB).”
3If the lens is provided with an extender, disengage
the extender function.
Similarly, if the lens is provided with a ratio
converter, disengage the ratio converter function.

Perform the menu operations (pages 70 to 72),
and display the “VF DISPLAY” screen of CAM
MAIN MENU 2.

Set ZEBRA1 DETECT to 70%, ZEBRA2
DETECT to 85% and ZEBRA2 to STOP.
(Default setting mode)
3
Press the MENU button and close the menu
screen.
4
Set the ZEBRA switch on the viewfinder to ON.
5Shoot a sheet of white paper devoid of color
irregularities.

Since flicker tends to occur under fluorescent
lights, mercury lamps and other such lights, use a
source of light such as sunlight or a halogen lamp
which does not tend to produce flicker.
6Set the lens aperture to manual, and adjust the
lens aperture in such a way that ZEBRA fills the
whole screen.
Check that the lens aperture is between F/4 and
F/11.

OSince unevenness in the lighting will make it
impossible for ZEBRA to fill part of the screen,
try adjusting the lighting position, etc.
OTry adjusting the lighting position, etc. also when
the lens aperture is not between F/4 and F/11.
OAlways be sure to leave the electronic shutter at
OFF.
