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

    The servo reference signal is switched as shown in the tables below depending on the servo
    reference setting, deck mode and what input signal is available. When the mode is
    transferred to editing or recording/playback, the image may be disturbed and the transfer
    may be delayed if the references during playback and recording do not match.

    							Audio V Fade Function
    When editing tapes, the edit point splicing selection (setting menu No. 309 and 310)
    information is recorded on the tape. This information is then sensed during playback, and V
    fade or cut processing is automatically performed for these sections. [However, only when
    the playback fade selection (No. 719) is AUTO.]
    When the edit point splicing selection (setting menu No. 309 and 310) is CUT
    Audio signal AAudio signal B
    Noise appears at the edit splice.
    When the edit point splicing selection (setting menu No. 309 and 310) is FADE
    Audio signal AAudio signal B
    V fade is performed instantaneously to eliminate the noise.
    
    When the playback fade selection (No. 719) is CUT, cut processing is performed for all
    splices.
    When the playback fade selection (No. 719) is FADE, V fade processing is performed for
    all splices.

    							Rack mounting
    The unit can be mounted into a 19-inch standard rack if the optional rack-mounting adaptors
    (AJ-MA34HP) are used.For the installation rails, it is recommended that the rail and
    bracket for 18 length (model number CC3001-99-0400) of SHASSIS TRAK be used. (The
    complete slide rail and bracket unit is not available from Panasonic) For further details,
    consult with your dealer.
    Remove the screws on the left and right sides of the unit.
    Use the removed screw to attach the inner members of the slide rails.
    Inner member
    The length of the screws used is subject to restriction. If some of the mounting screws
    have been lost or misplaced, use screws which are less than 4 long in their place.
    Use four screws to secure each inner member.
    Attach the outer member brackets to the rack.
    Check that the height is the same for the left and right brackets.
    Attach the AJ-MA34HP rack-mounting adaptors with included 4 screws.
    Remove 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.
    EIA standard rack
    Fasten it to the
    rack with set
    screws.
    
    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 has an auto head cleaning function which automatically reduces the dirt on the
    heads. However, to further increase the units reliability, it is recommended that its video
    heads be cleaned every day.
    Use the cleaning fluid designated by Panasonic.
    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 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.
