RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an 
equilateral triangle, is intended to alert the user to the 
presence of uninsulated “dangerous voltage” within 
the product’s enclosure that may be of sufficient 
magnitude to constitute a risk of electric shock to 
persons.
The exclamation point within an equilateral triangle is 
intended to alert the user to the presence of important 
operating and maintenance (servicing) instructions in 
the literature accompanying the appliance.
CAUTION:
To reduce the risk of fire or shock hazard and 
annoying interference, use the recommended 
accessories only.
THIS APPARATUS MUST BE EARTHED
To ensure safe operation the three-pin plug must 
be inserted only into a standard three-pin power 
point which is effectively earthed through the 
normal house-hold wiring.
Extension cords used with the equipment must be 
three-core and be correctly wired to provide 
connection to earth. Wrongly wired extension 
cords are a major cause of fatalities.
The fact that the equipment operates satisfactorily 
does not imply that the power point is earthed and 
that the installation is completely safe. For your 
safety, if in any doubt about the effective earthing 
of the power point, consult a qualified electrician.
WARNING:
To reduce the risk of fire or shock hazard, 
do not expose this equipment to rain or 
moisture.
FCC Note: 
This device complies with Part 15 of the FCC Rules. 
To assure continued compliance follow the attached 
installation instructions and do not make any 
unauthorized modifications.
This equipment has been tested and found to comply 
with the limits for a Class A digital device, pursuant to 
Part 15 of the FCC Rules. These limits are designed 
to provide reasonable protection against harmful 
interference when the equipment is operated in a 
commercial environment. This equipment generates, 
uses, and can radiate radio frequency energy and, if 
not installed and used in accordance with the instruc-
tion manual, may cause harmful interference to radio 
communications. Operation of this equipment in a 
residential area is likely to cause harmful interference 
in which case the user will be required to correct the 
interference at his own expense.
is the safety information.
CAUTION:
TO REDUCE THE RISK OF FIRE OR 
SHOCK HAZARD, REFER MOUNTING OF 
THE OPTIONAL INTERFACE BOARD TO 
AUTHORIZED SERVICE PERSONNEL.
CAUTION:
Do not install or place this unit in a bookcase, 
built in cabinet or in another confined space in 
order to keep well ventilated condition. Ensure 
that curtains and any other materials do not 
obstruct the ventilation condition to prevent 
risk of electric shock or fire hazard due to 
overheating.

General and Features
This u nit is a dig ital video  cassette  recorder which uses 1/4-inch tapes.
It incorporates digital compression technology so that the deterioration in picture quality and
sound quality resulting from dubbing is significantly minimized compared with existing analog
systems.
Furthermore, since it has a compa ct 4U size and light weight, the unit can be carried around
or mounted in a 19-inch rack with ease.
The  settings for the  unit’s setup can be performed while viewing the screen men us on the TV
monitor. When DVCPRO cassette tapes are used, both assemble and insert editing can be
performed by exercising control from an external component.
Features
Compact size and light weight
This is a 4 U size digita l VTR. It can be mounted in a 19-inch rack with ease using the optiona l
rack-mounting adaptors (AJ-MA75P).
Up to 184 minutes of recording
Two sizes of cassette tapes can be used with this unit: M cassette (max. 66 minutes) and L
cassette  (max. 184 min utes). The  width o f the tapes measures 1/4 inch to achieve a compact
design.
Compatibility with consumer products
This un it can play back consumer-use cassette tape s shot by a d igital camera or o ther
consumer component. It can also record on consumer-use cassette tapes using the DV
format. A cassette adapter (AJ-CS455P) is used for mini DV cassette tapes.
Digital slow motion/jog
The  slo w motion  playback images ca n be repro duced clearly at any of the spee ds given
below using commands from the external controller or other such device: –0.43/–0.3/–0.2/
–0.1/–0.03/0/+0.03/+0.1/+0.2/+0.3/+0.43.

• Some noise may occur when the slow motion speed is changed.
• When slow motion playback is used, the image shakes slightly in the vertical direction.
Dialy shuttle operation is possible through the external controller
Shuttle operations enable the tape to be played back with color images at a speed of up to
60 times normal tape speed in either the forward or reverse direction.
Time codes
This u nit comes with a built-in time code generato r (TCG)/time cod e reade r (TCR). In
addition to the internal time code, an external time cod e input or inp ut signal VITC can be
recorded in the machine.

• 9-pin (RS-422A)/RS-232C remote
The  standard 9 -pin se rial (RS-422A) connector or RS-232C co nnecto r is used.
2-channel high-sound-quality digital audio
Sound can be edited separately for two channels, and channel mixing capabilities are also
available. One channel is provided for the analog cue track.
Information selected from audio CH1 and CH2 can be recorded in the cue track memory.
(Set at the set up menu.)
• Cue track input and output connectors are not provided.
Automatic editing functions from the external controller
Both assemble and insert editing can be performed using an external controller (but only
when DVCPRO cassettes are used).
Menu-driven setup
