Time code and user’s bit
Time code
The time code is used when the time code signal
generated by the time code generator (time code
signal generator) is to be recorded on the tape, its
values are to be read by the time code reader (time
code signal reader), and the absolute position of the
tape is to be displayed in increments of hours,
minutes, seconds and frames.
The time code is written in the sub-code area (data
area) of the helical track.  This enables insert editing
to be conducted independently using the time code
alone.  In addition, the VTR’s playback speed can be
read from the stop mode to the slow motion playback
up to high-speed playback (approx. 50k
normal
speed or approx. 100k
normal speed when using a
DVCPRO tape).
The time code values are indicated on the display and
superimposed display.

Hours Minutes Seconds Frames
User’s bit
The “user’s bit” refers to the 32-bit (8-digit) data frame
among the time code signals which has been released
to users.  It enables operator numbers and other
values to be recorded.
The alphanumerics which can be used for the user’s
bit are number 0 to 9 and letters A to F.
Setting the internal time code
1Set the VTR to the stop mode.
4Setting  RUN MD on the  menu
REC: 
The time code advances simultaneously with the
recording.
FREE: 
The time code advances, like time, irrespective of
the VTR operation.F5
5Setting  TCG MD on the  menu
REGEN: 
The continuity of the underlying time code in place
prior to editing is maintained.
PRE: 
The time code can be preset using the operation
panel controls or remote controller.
AUTO: 
The time code is automatically switched to REGEN
or PRE depending on the VTR
’s operation mode:
during editing, REGEN is selected; at all other
times, PRE is selected.

When the number key corresponding to the channel
whose signals are to be monitored is pressed while
the “L” (or “R”) button is held down, that channel is
selected, and its signals are displayed on the audio
level meter.  (The same steps can also be taken to
de-select a channel which has already been selected.)
However, only up to 2 channels among the CH1-CH4
channels and only up to 2 channels among the CH5-
CH8 channels are selected.

Display saving function
This function is provided to extend the service life of the
LCD monitor.  It starts up if none of the front panel
controls have been operated or the cassette tape has not
been run at all for about 5 minutes.
While the saving function is working, the LCD monitor
display goes blank, and the “EX” symbol appears on the
time code display area.
To release the saving function, operate a button or dial
on the front panel or issue a tape transport command
from the controller.  The operation performed to release
the function will be executed after the function is
released.

2Attach the outer member brackets to the rack.
Check that the height is the same for the left and
right brackets.
3Remove the four screws at the front used to attach
the left and right side panels.
4Attach the AJ-MA75P rack-mounting adapters
using the same four screws.
1Attach the inner members of the slide rails.  Refer
to the figure below for the positions where they are
screwed into place.  The unit can be mounted into a 19-inch standard rack
if the optional rack-mounting adapters (AJ-MA75P)
are used. For the installation rails, it is recommended
that the rail and bracket for 18-inch length (part
number CC3061-99-0400) of Chassis Trak be used. If
an even greater clearance is to be left between the
VTR and rack when the VTR is pulled out, however, it
is recommended that the 22-inch long Chassis Trak
(part number CC-3001-99-0191) be used.
(The complete slide rail and bracket unit is not
available from Panasonic.) 
For further details, consult your dealer.
Rack mounting
 
•The length of the screws used is subject to a
restriction.  
•Use screws which are less than 2/5q
(10 mm)
long.
•
Attach the inner member at the same symmetrical
positions on the left (L) side as well.  Fix the
members in place using 3 screws on each side
(total: 6 screws). When using the 22-inch long slide
rails, secure the screws at 4 locations.
•The letters shown in the figure are not actually
marked on the side panels.

of the VTR, and install the VTR in the rack.
After the VTR has been installed, check that it
moves smoothly along the rails.
EIA standard rack
Fasten to rack with the
fixing screws.
 
•Keep the temperature inside the rack to between
41
xF and 104xF(5xC and 40xC).
•Bolt the rack securely to the floor so that it will not
topple over when the VTR is pulled out.

This VTR is equipped with an auto head cleaning
function which automatically reduces the amount of
dirt on the video heads.  In order to maximize the
VTR’s reliability, however, it is recommended that the
video heads be cleaned as and when appropriate.For further details on how to actually clean the heads,
consult with one of Panasonic’s service companies or
with your dealer.
Video head cleaning
Condensation occurs due to the same principle which
is involved when droplets of water form on a window
pane of a heated room.  It occurs when the VTR or
tape is moved between places where the temperature
or humidity varies greatly or when, for instance:
•It is moved to a very humid place full of steam or a
room immediately after it has been heated up.
•It is suddenly moved from a cold location to a hot or
humid location.
After moving the VTR to such a location, leave it
standing for about 10 minutes rather than switching on
its power immediately.If condensation has formed on or in the VTR, the
AUTO OFF lamp lights, and the cassette tape is
automatically ejected.Keep the power supplied and
simply wait until the AUTO OFF lamp goes off.
It is recommended that the video heads be cleaned
after the AUTO OFF lamp has gone off.
Condensation
Before proceeding with maintenance, be absolutely
sure to set the power switch to OFF and take hold of
the power plug and unplug it from the power outlet.
Use a soft cloth to clean the cabinet.  To remove
stubborn dirt, dilute some kitchen detergent, dip a
cloth into the solution, wring it out well, and wipe.
After having removed the dirt, take up any remaining
moisture using a dry cloth.  
Do not use alcohol, benzene, paint thinners or other
solvents.  They can discolor the external parts
surfaces and remove the finish.

When a warning occurs in this VTR, the warning lamp
lights up.
When the DIAG menu is opened, a description of the
warning will appear on the front panel LCD area and
TV monitor.  Also, when an abnormal operation is
detected in this VTR, the AUTO OFF lamp lights up,
and a message appears on the time code display
area.

This displays the VTR information.
The VTR information includes the warning information
and hour-meter (usage time) information.  The DIAG
menu appears on the front panel LCD display or on a
TV monitor when the TV monitor is connected to the
VIDEO OUT3 connector in the VTR’s connector area.
