Error No. Error message and description Error No. Error message and description
Condensation
Condensation forms in the unit and on the tape following the same principle which is behind the
formation of droplets of water (condensation) on the window panes of a heated room.  This
phenomenon occurs when the unit or tape is moved to a location with significantly different
temperature and humidity levels.  Condensation forms when:
OThe unit (or tape) is moved to a high-humidity place filled with steam or to a room immediately
after it has been heated up.
OThe unit (or tape) is suddenly moved from a cool place to a place with high temperature and
humidity levels.
When the unit (or tape) has been moved to such a place, do not turn on the power immediately
but leave the unit (or tape) standing for about 10 minutes.  When condensation has formed in the
unit, the “– – d – –” error message lights on the counter display, and the cassette tape is
automatically ejected.
Keep the power on, and wait until the error message is cleared.
E – 04
UNKNOWN SIG
This appears when the format of the signals
supplied to the digital video interface is neither
DVCPRO nor DV.
It also appears when two AJ-HD1200A units are
used as the input and output units and different
settings are selected for the menu item No.25
[SYSTEM FREQ] of the two units.

E – 16
INVALID VIDEO SIG
This appears when the video signals supplied to the
digital video interface are not the correct ones.
Operation performed by AJ-HD1200A
Operation is continued (

This appears when the time code signals supplied to
the digital video interface are not the correct ones.
Operation performed by AJ-HD1200A
Operation is continued (
23).
E – 90
NOT 1X 100M SIG
This appears when the signals supplied to the digital
video interface do not have the 1ktransfer speed of
the DVCPRO HD (100 Mbps) format.
Operation performed by AJ-HD1200A
Operation is continued (
21).
E – 92
1394 INITIAL ERROR
This appears when the initialization process fails
during communication via the digital video interface. 
Operation performed by AJ-HD1200A
Operation is continued (
24).

In such a case, black signals are recorded as the video signals, and the audio signals are muted.
22:This error message always appears in the E-E mode.
In such a case, the audio signals are muted.
23:This error message always appears in the E-E mode.
In such a case, the time code of the time code generator inside the AJ-HD1200A is recorded as the time code signal.

Video head cleaning
This unit comes with an auto head cleaning function which reduces the amount of dirt on the
heads automatically.  However, in order to improve the unit’s reliability, it is recommended that
the video heads be cleaned on a daily basis.  Use the cleaning fluid specified by Panasonic.
Maintenance
Before proceeding with maintenance, set the power switch to OFF, and be absolutely sure to
hold the molded part of the power plug to disconnect it from the power outlet.
Clean the cabinet using a soft cloth.  To remove stubborn dirt, dilute some kitchen detergent,
soak a cloth in the solution and wring it out well, and then wipe away the dirt.  After wiping off the
dirt, use a dry cloth to take up the remaining moisture.  Do not use paint thinners or benzine.
Emergency eject
1Remove the top panel.
2Use a Phillips-head screwdriver to push in the red
plastic gear (A) and turn it counterclockwise while
keeping it pushed in.  The mechanism that winds
up the tape is activated by this, and it makes a
latching sound.  Ignore the sound, and turn the gear
through about 10 revolutions.

Turning the gear more than necessary will strain
the cassette, possibly resulting in tape damage.
Procedure to ejecting the tape manually in an emergency
If the cassette tape fails to be ejected even when the EJECT button is pressed, it can be ejected as follows.
OFollow the steps below after making absolutely sure that the unit’s power has been turned off.

4 3Check that the posts have unloaded the tape and
that the tape is completely housed inside the
cassette.
4Once the tape has been completely returned inside
the cassette case, use the Phillips-head
screwdriver to push in the red plastic gear (B) in
front of the cassette down motor’s worm gear and,
while keeping it pushed in, turn it clockwise to eject
the cassette.

When closing the cassette cover, take care not to
catch the tape.
