Panasonic Aj D440 Aj D450 Operating Instructions Manual

							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.
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.
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-MA75P 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.

Video head cleaning
This unit has an auto head cleaning function which automatically reduces the dirt on the 
heads. However, to further increase the unit’s reliability, it is recommended that its video 
heads be cleaned every day.
Use the cleaning fluid designated by Panasonic.
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.
