EMERGENCY
screw

ODo not turn the EMERGENCY screw except in an
emergency.
ODo not turn the screw clockwise.  Stop turning the
screw as soon as the tape is ejected.  Otherwise,
the mechanism may be damaged.
OAfter the tape is ejected, the cassette holder will not
lock into place even when an attempt is made to
close it.  Be sure to turn the power off and turn it
back on to reset the mechanism’s operation, and
then close the cassette holder.
OA clicking sound will be heard when the
EMERGENCY screw is turned: this sound is made
by the reel drive operation and is therefore not
indicative of a malfunction.
OThis screw needs to be rotated through about 20 turns
after the first turn until the unloading can be started.
OThis screw needs to be rotated through about 90 turns
after the first turn until the tape is ejected.
Emergency eject
If the cassette cannot be ejected by pressing the
EJECT button, use a screwdriver or similar tool to
press and turn the EMERGENCY screw.  This
enables the cassette to be removed.

Maintenance
The water vapor in the air may form as tiny droplets
on the head drum when the unit is moved from a cold
location to a warm location or used in a very humid
place.  This phenomenon is known as condensation,
and running the tape under these conditions is liable
to cause the tape to stick to the drum.
Note the following points:
ORemove the tape when the unit’s operation is to be
started in conditions where condensation may form.
OBefore loading the tape, set the power switch to
ON, and check that the HUMID display is not
lighted in the display window.

For safety reasons, the HUMID display will flash and
the drum will rotate for 80 minutes after condensation
detection is released.
During this time, the operation buttons cannot be
operated.
Check that the HUMID display
is not lighted.
Condensation
Use the AJ-CL12LP cleaning cassette if the heads
need to be cleaned.  Take care to read the
instructions accompanying the cleaning tape since the
video heads may be damaged if the tape is not used
in the correct way.
Head cleaning
ODo not use thinners or any other solvent to remove
dirt.
OUse a lens cleaner available on the market to wipe
the lens.
ONEVER wipe the mirror.
If dirt or dust has found its way onto the mirror,
remove it using an air blower available on the
market.
Cleaning inside the viewfinder
Smear
This phenomenon may occur when very bright
subjects are shot.
The faster the electronic shutter speed, the more likely
that it will occur.
Phenomena inherent to CCD
cameras
Replacing the backup battery
The backup battery is already installed when the unit
is shipped.
When it has discharged, the “BACK UP BATT
EMPTY” display appears for 3 seconds on the
viewfinder screen when the POWER switch is set to
ON.
Moreover, the time code value of the TCG will be set
to “00:00:00:00” and the backup of the time code
value will no longer be possible: this means that the
backup battery should be replaced.
Consult with your nearest service center, and replace
the spent battery with a new battery (CR2032 or
BR2032).

Inspections prior to shooting
Perform the following inspections prior to shooting to
check that the systems are operating properly.
It is recommended that the images be checked using
a color monitor.

2Set the POWER switch to ON, and check that the
HUMID display has not come on and that at least 5
segments of the BATTERY display are lighted.
OIf the HUMID display has come on, wait until it
goes off.
OIf fewer than 5 segments of the BATTERY
display have lighted, replace the battery with
one having an adequate charge.
3After checking that there are no cables near the
cassette holder or top panel, press the EJECT
button to open the cassette holder.
4After checking the following points, load the
cassette tape and close the cassette holder.
OThe cassette tape must not be set to the
