Ð 82 Ð 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 unitÕs mode and servo reference stand in the relationship shown in the flowchart presented below. EXT 1 2 What is the SERVO REF on the setup menu No. 304 setting? 3Is the unit in the editing mode? (Is VIDEO, CH1, CH2, CUE or TC selected?) 4Is the REF VIDEO signal supplied? YESYES Is the unit in the recording mode? AUTO YES NO NO NO NO YES Is the input video signal available? The REF VIDEO input signal serves as the reference signal.The internal sync signal serves as the reference signal.The input video signal serves as the reference signal.
Ð 83 Ð Servo reference setting tables 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. n During playback or special playback SERVO REF Input signal status Reference signal on the setup menu (servo reference) No. 304 position VIDEO IN signal REF IN signal REF IN signal AUTO ´Internal sync signal ´REF IN signal ´´Internal sync signal REF IN signal EXT ´Internal sync signal ´REF IN signal ´´Internal sync signal n During recording or editing SERVO REF Input signal status Reference signal on the setup menu (servo reference) No. 304 position VIDEO IN signal REF IN signal VIDEO IN signal AUTO ´VIDEO IN signal ´REF IN signal ´´Internal sync signal REF IN signal EXT ´Internal sync signal ´REF IN signal ´´Internal sync signal Ò Ó denotes that the signal is supplied: Ò´Ó denotes that the signal is not supplied.
Ð 84 Ð Audio V Fade Function When editing tapes, the edit point splicing selection (setup 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 (setup menu No. 309 and 310) is CUT Audio signal A Noise appears at the edit splice.Audio signal B When the edit point splicing selection (setup menu No. 309 and 310) is FADE Audio signal A Audio 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.

Ð 86 Ð 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 CC3001-99-0400) of CHASSIS TRAK be used. (The complete slide rail and bracket unit is not available from Panasonic) For further details, consult with your dealer. 1Remove the screws on the left and right sides of the unit. 2Use 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 0.4 long in their place. Use four screws to secure each inner member. 3Attach the outer member brackets to the rack. Check that the height is the same for the left and right brackets. 4Attach the AJ-MA75P rack-mounting adaptors with included 4 screws. 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.
Ð 87 Ð 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. Video head cleaning This unit has an auto head cleaning function which automatically reduces the dirt on the heads. However, to further increase the unitÕs reliability, it is recommended that its video heads be cleaned every day. Use the cleaning fluid designated by Panasonic.
Ð 88 Ð Error messages When a warning occurs in this unit, the warning lamp lights up. Opening the DIAG menu will display the warning description on the counter display and the monitor. Also, when an abnormal operation is detected in this unit, the AUTO OFF lamp lights up and a message appears on the counter display. DIAG menu This display the VCR information. VCR information includes ÒWARNINGÓ information and ÒHOURS METERÓ (usage time) information. A DIAG menu appears on the monitor when the monitor is connected to the VIDEO OUT 3 connector on the connector section. Displaying the DIAG menu 1Press the DIAG button. The DIAG menu screen is displayed on the monitor, and the message is displayed on the counter display. 2The ÒWARNINGÓ information and ÒHOURS METERÓ information can be switched by pressing the search buttons. 3Press the DIAG button again to return to the original display.

When an abnormal operation is detected in this unit, the AUTO OFF lamp lights up and an error message is displayed. If ÒBBÓ in No. 601 (INT BB SIG) in the setup menu is selected or when ON has been selected as the setup menu No. 722 (INT SG) setting, pressing the REC button or the EDIT button (E to E mode) will display ÒINT SGÓ for the first two seconds. This is also displayed for the first two seconds when starting editing. If there is no input signal (except for analog audio) to the connector selected using the INPUT SELECT switch, pressing the REC button or the EDIT button (E to E mode) will display ÒNO INPUTÓ for the first two seconds. This is also displayed for the first two seconds when starting editing. When a warning occurs in this unit, the warning lamp lights up and a warning message is displayed. When multiple warnings occur, the warning with the highest priority is displayed. This is displayed when the fan motor stops. This is displayed when the servo is not locked for three or more seconds during playback, recording, or editing. This is displayed when envelope levels approximately 1/3 that of normal levels are detected for more than one second during playback, recording, or editing. This is displayed when the error rate increases and correction/interpolation is performed on either the video or audio playback signal. When voice-over editing is performed using the internal audio memory, this message appears if the duration of the signals recorded in the memory exceeds 20 seconds.
