Servo reference
As the servo reference signal, this unit automatically selects the input video signal selected
by the VIDEO INPUT switch, the reference video signal which is supplied from the REF
VIDEO input connector or the internal sync signal.
When the signal is selected, the unit’s mode and servo reference stand in the relationship
shown in the flowchart presented below.

Rack mounting
The unit can be mounted into a 19-inch standard rack if the optional rack-mounting adaptors
(AJ-MA75P) are used. For the installation rails, it is recommended that the rail and bracket
for 18 length (model number CC3061-99-0400) of Chassis Trak be used. (The complete
slide rail and bracket unit is not available from Panasonic.) For further details, consult with
your dealer.
1Refer to below for the places where they are to be secured with the screws.
ABCDEFGHAttach the inner members at the 
same symmetrical positions on the 
left (L) side.
Note: The letters “A” to “H” are not 
actually marked on the side 
panels.
Inner member Locations where the screws are secured on right (R)
side of inner members of slide rails
The length of the screws used is subject to restriction. Use screws which are less than
2/5 long in their place.
6 screws must be used to secure each inner member.
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 for attaching the left and right side panels.
4Attach the AJ-MA75P rack mount adapter using the 4 screws included.
Rack-mounting adaptors
5Remove the 4 rubber legs from the bottom of the unit, and install the unit in the rack.
After the unit has been installed, check that it moves smoothly along the rails.
Fasten it to the
rack with set
screws.EIA standard rack

•Keep the temperature inside the rack to between +41°F (5°C) and +104°F (40°C).
•Bolt the rack securely to the floor so that it will not topple over when the VTR is drawn out.

Video head cleaning
This unit is equipped with an auto head cleaning function which automatically reduces the
amount of dirt on the video heads. However, in order to maximize the unit’s reliability, 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 our service
companies or with your dealer.
Condensation
Condensation occurs due to the same principle involved when droplets of water form on a
window pane of a heated room.  It occurs when the unit 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.
When moving the unit to locations such as these, leave it standing for about 10 minutes
rather than switching on the power immediately.
If condensation has formed on or in the unit, the “E-20” code flashes in the counter display
and the cassette tape is automatically ejected.
Keep the power supplied and simply wait until the “E-20” code goes off.

Do not use alcohol, benzine, paint thinners or any other solvents. They cause discoloration of
the unit’s external parts surfaces and mar the paint finish.
Installing the mechanism dust protector
Mechanism dust protector
ProtrusionProtrusion wInsert the protrusion 
under the top-front 
metal plate.
qInsert the protrusion 
alongside the metal 
plate inside the 
mechanism.

Do not insert fingers or any objects into the video
casette holder.

Avoid operating or leaving the unit near strong
magnetic fields. Be especially careful of large audio
speakers.

Avoid operating or storing the unit in an excessively hot,
cold, or damp environment as this may result in damage
both to the recorder and to the tape.

Do not spray any cleaner or wax directly on the unit.

If the unit is not going to be used for a length of time,
protect it from dirt and dust.

Do not leave a cassette in the recorder when not in use.

Do not block the ventilation slots of the unit.
Use this unit horizontally and do not place anything on
the top panel.

Cassette tape can be used only for one-side, one
direction recording. Two-way or two-track recordings
cannot be made.

Cassette tape can be used for either Color or Black &
White recording.

Do not attempt to disassemble the recorder.
There are no user serviceable parts inside.

If any liquid spills inside the recorder, have the recorder
examined for possible damage.

Refer any needed servicing to authorized service
personnel. CAUTION:
These servicing instructions are for use
by qualified service personnel only. To
reduce the risk of electric shock do not
perform any servicing other than that
contained in the operating instructions
unless you are qualified to do so.

When condensation is detected, the error no. display
flashes, and the unit goes into EJECT mode. The drum
rotates after the cassette tape is ejected to remove
condensation.

when the unit is in EJECT mode.
2) When condensation is detected while a cassette tape is
inserted, drum rotation stops, the cassette tape is ejected
and the drum rotation begins again.
If any other number appears frequently, ask your dealer to
inspect the unit.
