7Use the lens VTR button to check the same operations
as in steps  5and  6.
8Press the RESET button, and check that  “00:00:00:00 ”
appears on the counter display.
9Set the LIGHT switch to ON, and check that the display
window illuminates.
10Press the REW button, and after the tape has been
rewound for a few seconds, press the PLAY/PAUSE
button.
Check that the tape is recorded, played back and
rewound properly.
11Press the FF button, and check that the tape is fast
forwarded properly.
2. Automatic audio level adjustment function inspection
1Set the AUDIO SELECT CH1 and CH2 switch to AUTO.
2Set the AUDIO IN CH1 and CH2 switches to FRONT.
3Point the microphone connected to the MIC IN jack at a
suitable sound source, and check that the changes in
the level displays for both CH1 and CH2 reflect the
changes in the strength of the sound.
3. Manual audio level adjustment functioninspection
1Set the AUDIO IN CH1 and CH2 switches to FRONT.
2Set the AUDIO SELECT CH1 and CH2 switch to MAN.
3Turn the AUDIO LEVEL CH1 and CH2 controls.
Check that when they are turned clockwise, the level
displays increase.
4. Earphone and speaker inspection
1Set the VTR SAVE/STBY switch to STBY.
2Turn the MONITOR control, and check that the speaker
volume changes.
3Connect the earphones to the PHONES jack.
Check that the sound from the speaker is muted, and
that the microphone ’s sound is heard in the earphones.
4Turn the MONITOR control, and check that the
earphone volume changes.

5. Inspection using external microphones
1Connect external microphones to the AUDIO IN CH1
and CH2 jacks.
2Set the AUDIO IN CH1 and CH2 switches to REAR.
3Set the LINE/MIC/+48V selector switch on the back
panel to MIC or +48V in accordance with the external
mic’s power supply type.
MIC : Internal power supply mic.
+48V : External power supply mic.
4Point the microphones at the sound source, and check
that the changes in the audio levels displayed on the
audio level meter of the display window and in the
viewfinder reflect the changes in the strength of the
sound.
This inspection can also be performed for each channel
by connecting one of the microphones to each channel
in turn.
6. Inspections relating to the time code and user
bits
1Set the user bits as required.
For details on the setting procedure, refer to  “4-5-1
Setting the user bits. ”
2Set the time code.
For details on the setting procedure, refer to  “4-5-3
Setting the time code. ”
3Set the TCG switch to R-RUN.
4Press the REC START button.
Check that the figure on the counter display changes as
the tape travels.
5Press the REC START button again.
Check that the tape stops and the figure shown on the
counter display stops changing.
7Set the DISPLAY switch to UB.
Check that pressing the HOLD button advances the
display value through the sequence VTCG  >DATE  >
TIME  >no display (time zone)  >TCG.
6Set the TCG switch to F-RUN.
Check that the figure on the counter display changes
irrespective of the tape travel.
6-1-4 Self-diagnosis function
Simplified checks can be undertaken on the unit ’s system at
such times when, for instance, a color video monitor is not
available.
Perform menu operations to open the 
from the MAINTENANCE page. Check the camera output
level setting under the COLOR CHECK item.

6-2 Maintenance
6-2-1 Condensation
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:
≥Remove the tape when the unit ’s operation is to be started
in conditions where condensation may form.
≥ Before 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.
6-2-2 Head cleaning
Use the AJ-CL12MP 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.
6-2-3 Cleaning inside the viewfinder
≥ Do not use thinners or any other solvent to remove dirt.
≥ Use a lens cleaner available on the market to wipe the
lens.
≥ NEVER wipe the mirror.
If dirt or dust has found its way onto the mirror, remove it
using an air blower at retail outlets.
6-2-4 Phenomena inherent to CCD
cameras
Smear
This phenomenon may occur when very bright subjects are
shot.
This phenomenon is more conspicuous when the electronic
shutter speed is faster.
White dot defects
For shooting in a high temperature environment using the DS
GAIN, red, green, or blue dots may appear on the screen.
Adjust the DS. GAIN and the S. GAIN in accordance with the
operating environment.
6-2-5 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 dealer, and replace the spent battery with
a new battery (CR2032).

6-3-3 Emergency eject
If the cassette cannot be ejected by pressing the EJECT button, use a sc\
rewdriver or similar tool to press and turn the
emergency eject screw.  This enables the cassette to be removed.
1Set the power to OFF.
4Remove the cassette.
5Return the rubber cap to its original position.
2Remove the rubber cap where shown in the figure.
Insert a Phillips head screwdriver into the cross-shaped
part of the emergency eject screw (red).
3While pushing in with the screwdriver, turn the
emergency eject screw counterclockwise until the tape is
ejected.
≥This screw needs to be rotated through about 20 turns
after the first turn until the unloading can be started.
≥ It also needs to be rotated through about 90 turns after
the first turn until the tape is ejected.

mechanism may be damaged.
≥ After 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.
≥ A clicking sound will be heard when the emergency eject
screw is turned: this sound is made by the reel drive
operation and is therefore not indicative of a malfunction.
