Selecting the video input signals
The following three kinds of video signals can be
supplied to the unit.  
They are selected using the video input selector
switch and camera input selector switch.
OTo select the composite video signals which are to
be supplied to the VIDEO IN connector, set the
video input selector switch to the VIDEO IN
position.

Bear in mind that stable recording may not be
possible if non-standard signals are supplied.
OTo select the signals which are to be supplied to the
CAMERA connector, set the video input selector
switch to the CAMERA position.
To select either component signals or composite
signals as the video signals supplied from the
camera, use the camera input selector switch.
Video input level display method
Whether the video input signals are being supplied
can be monitored on the level meter of the signal level
display window.

Check the video input level using 75% SMPTE color
bar signals.  The level will not be displayed properly if
other video signals are used.

The camera’s component signals are set to the
Betacam component level.  To set them to the M
II
level, first consult your dealer, and then set SW1 on
the VIDEO JACK circuit board (located inside the
connector panel) to the M
IIposition.

How to set the time code

If both the user’s bit and time code are to be used, set
the user’s bit first.
If the time code is set first, the time code generator
will stop while the user’s bit is being set so that the
time code setting will be off.  The range in which the
time code can be set extends from 00:00:00:00 to
23:59:59:29.
Concerning the time codes when the battery is
replaced
The backup mechanism is still operational even when
the battery is being replaced, and the time code
generator continues operating for an extended period
of time (approx. one year).Set the DISPLAY switch to the TC position.1
Set the TCG selector switch to the SET
position.2
Select DF or NDF as the setup menu item No.
510 (DF MODE) setting.
DF:When the time code is to be advanced in
the drop frame mode
NDF:When the time code is to be advanced in
the non-drop frame mode3
Set the time code using the SHIFT button as
well as the “+” and “–” buttons.
SHIFT button:
This causes the digit to be set to flash.
Each time it is pressed, the flashing digit
moves to the right.
“+” button:
This increases the flashing digit by 1.
“–” button:
This decreases the flashing digit by 1.4
Set the TCG selector switch to the F-RUN or R-
RUN position.
F-RUN:When the time code is to be advanced
in the free run mode
R-RUN:When the time code is to be advanced
in the rec run mode

OAt the R-RUN position, the first recording to be
made after the time code has been set starts
from the value which was just set.  However, if
the time code was not set, recording starts at
the value which continues on from the value
which is read out from the tape.
OSelect PRESET for the setup menu item No.
532 setting in order to prevent the time code
from continuing on from the value which is read
out from the tape when recording after the
cassette has been inserted or after the stop
mode has been established.5

How set to the user’s bit
By setting the user’s bit, a memo (time or date) or
other information using up to 8 hexadecimal digits can
be recorded on the sub-code track.
Concerning the user’s bit memory function
The user’s bit setting is automatically stored in the
memory and retained even when the unit’s power is
turned off.

When TIME or DATE has been selected with the UB
MODE setting, the date or time which was set using
setup menu item No. 540 (TIME/DATE) is entered in
the user’s bit.Set the DISPLAY switch to the UB position.1
Set the TCG selector switch to the SET
position.2
Select USER as the setup menu item No. 530
(UB MODE) setting.3
Set the user’s bit using the SHIFT button as
well as the “+” and “–” buttons.
SHIFT button:
This causes the digit to be set to flash.
Each time it is pressed, the flashing digit
moves to the right.
“+” button:
This increases the flashing digit by 1.
“–” button:
This decreases the flashing digit by 1.4
OA through F in hexadecimal notation are displayed as
shown in the table below.

OWhen TIME is selected, the hours, minutes and
seconds are entered in the user’s bit.
OWhen DATE is selected, the year, month, day and
hours are entered in the user’s bit.

Procedure for locking to the external time code
When connecting two or more AJ-D92 units and
locking the time code
Set the TCG selector switch on each AJ-D92 unit to
the F-RUN position.
Once the operation to lock the time code to the
external time code has been performed, the time code
is instantly locked to the external time code, and the
same value as the external time code value is
displayed on the counter.  Do not set the unit to the
recording mode for the several seconds it takes until
the time code stabilizes.
Concerning the user’s bit setting while the time
code is locked to the external time code
While the time code is locked to the external time
code, only the time data is locked to the time data of
the time code supplied from the external source.
This means that the user’s bit can be set separately
for each unit.
In order to lock the user’s bit to the user’s bit of the
time code supplied from the external source, set it to
the EXT mode which is set using setup menu item No.
530.
To release the time code from being locked to the
external time code
First stop supplying the external time code, and then
set the TCG selector switch to the R-RUN position.
When switching the power supply from the battery
to AC adaptor while the time code is locked to the
external time code
In order to ensure that the time code generator’s
power supply remains uninterrupted, first connect the
AC adaptor to the DC IN socket, and then disconnect
the battery pack.  If the battery pack is disconnected
first, no guarantees can be made for the continuity of
the locking to the external time code. Set the unit’s POWER switch to ON.

Set the TCG selector switch to the F-RUN
position.2
Set the DISPLAY switch to the TC position.3
Supply the reference time code and reference
video signals whose phase correlation meets
the time code standard to the TC IN connector
and VIDEO IN connector, respectively.4

Recording Operations
1. Recording using the CAMERA
connector
Set the video input selector switch to the
CAMERA position.1
Press the REC button and PLAY button at the
same time.
The unit is now set to the standby mode.

Since recording will start immediately at this point if
the camera’s VTR start/stop button is at the start
setting, make sure that the button is at the stop
setting.2

OIf the signals (component video signals or
composite video signals) selected using the
CAMERA input signal selector switch are not
supplied to the CAMERA connector, the
mismatching detector circuit is activated, the unit is
set to the REC PAUSE mode, and recording is not
commenced.
OThe detector circuit is activated and the unit is set
to the REC PAUSE mode also when the signals are
interrupted during recording.
When the signals are restored, recording will
automatically recommence.
When the detector circuit is activated in the above
way and the REC PAUSE mode is established, error
code [E-A0] and the time data will be displayed
alternately in the status display window.
However, recording will only be continued if ON has been
selected as the setup menu item No. 130 (NO VIDEO REC)
setting.
In this case, input signal error is indicated by the warning
lamp and alarm.
Press the camera’s VTR start/stop button to
start recording.
When the REC lamp inside the viewfinder stops
flashing and lights, recording is commenced.

The frame-to-frame continuity mode is established
when the VTR start/stop operations are performed
at the camera.  (This mode can be changed using
setup menu item No. 110.)3
Press the unit’s STOP button when recording is
to be ended.4
