WARNING PRECAUTIONS
• Main supply:
AC 230V, 50 Hz only
• Do not remove panel covers by unscrewing them.
ENGLISH
There are no user-serviceable parts inside. Refer
all servicing to qualified service personnel.
• To prevent fire or shock hazard, do not expose
this unit to rain or moisture.
Safety
• Should any solid object or liquid fall into the cabinet, turn off the unit and have it checked by qualified personnel before operating it any further.
• To disconnect the mains lead, pull it out by the
plug. Never pull the lead itself.
Installation
• Choose a location in which air can pass through
the ventilation holes in the bottom, top and back
of the unit to prevent it from overheating.
• Do not install the unit near heat sources such as
radiators or air ducts or in a place subject to direct
sunlight, excessive dust, mechanical vibrations or
shock.
• Do not place heavy objects or heat-generating
objects on the VCR, or the cabinet could be damaged or the temperature inside the VCR could
rise, which could cause a fault.
• Never bring a magnet or magnetized object near
the VCR because it will adversely affect the performance of the VCR.
• Do not install the unit in an inclined position.
The unit is designed for operation in a horizontal
position.
• Do not place a container with water or any small
metal objects on the VCR: If spilled water or a
metal object, such as paper clip, enters the VCR, it
could cause a fire or electric shock.
Operation
• Condensation
If you pour a cold liquid into a glass, water vapor
in the air will condense on the surface of the
glass.
This is the condensation of moisture.
Condensation on the head drum, one of the most
crucial parts of the VCR, will cause damage to the
tape. The VCR should not be operated for at least
2 hours after being moved from a cold to a hot
environment to avoid condensation from occurring on the head drum.
Cleaning
• Be careful; when the surface of the case is wiped
with a volatile agent such as benzine, alcohol,
thinner, etc., or a chemically processed cloth, the
surface finish may be degraded or its coating may
peel off.
Repacking
• It is wise to save the packing materials and box in
case you ever need to ship or store your unit.

INSTALLATION
VIDEO CONNECTIONS
Use coaxial cables when connecting a camera and a
monitor to this VCR.
Note: Long cable runs to distant cameras may
ENGLISH
cause signal deterioration and/or sync discrepancies. If these problems occur, use video line
amplifiers and/or cameras having phase-adjustable
line-locked vertical sync.
Video Input
In single camera systems, connect the camera to the
Video IN BNC terminal on the VCR rear panel. Use
of a 2:1 interlace camera is highly recommended;
otherwise, the monitor will show vertical distortion
of the TIME/DATE characters.
In multiple camera systems, connect the switcher
output to the Video IN BNC terminal. Because multiple camera systems require synchronization, use
of cameras having line-locked vertical sync or a genlocked master drive/sync source is highly recommended. The use of vertical interval switchers
is also recommended.
Video Output
Connect the monitor to the Video OUT BNC terminal
on the rear panel.
AUDIO CONNECTIONS
Note: Audio recording can be performed at the 03,
12 and 24-hour recording speeds and audio playback at the 03, A12, and A24 speeds.
Audio In: Accepts an audio signal from a camera,
external sound equipment, or another recorder
(Line: –8 dBm, 50 kohm).
Audio Out: Provides an audio output for a monitor
or another recorder (–9 dBm, 600 ohm, unbalanced).

ALARM IN
You can connect an alarm switch with a resistance
of 1 kohm or less or a door sensor. Connect pin q
to !5 or !6 (ground) through the switches.
Note: Do not apply a voltage to pin q , !5 or !6.
ALARM OUT
Approx. 12V is applied to pin w during an alarm
recording.
Notes:
• When you have selected “PULSE” in the “ALARM
OUT” menu in the ALARM display, approx. 12V
pulses will be applied to the output after the
alarm recording ends.
• When you have selected “DURATION” in the
“ALARM OUT” menu in the ALARM display, no
voltage is applied after the alarm recording ends.
• The output impedance is approx. 100 ohm.
TAPE END OUT
Approx. 12V is applied to pin r when the tape
reaches the end.
Notes:
• This does not operate when you have selected
“REW, RE-REC” in the “RECYCLE FUNCTIONS”
menu in the ALARM display or you have selected
“REWIND, STOP IF ALARM” and no alarm recording has been made.
• The output impedance is approx. 100 ohm.
TAPE END RESET
The TAPE END OUT can be turned off when pin t is
shorted to pin !5 or !6.
Note: Do not apply a voltage to pin t , !5 or !6.
WARNING OUT
When an abnormality has occurred in this VCR,
approx. 5V is output to pin y to warn the user.
TIME ADJUST
When two or more of this VCR model are used, connect via these terminals. With only one VCR, specify TIME ADJUST: MASTER, in [OPTIONS] items on
the CLOCK SET display. Specify TIME ADJUST:
SLAVE (default setting at the factory) for all other
VCRs. Each time “2:00:05” is reached, the VCR set
to MASTER transmits pulses for adjustment to the
VCRs set to SLAVE. When the VCRs set to SLAVE
receive these pulses, their clocks will adjust to the
same time as the clock in the VCR set to MASTER.
Notes:
• Do not connect any device to pin e , u , !1 , !2.
• Be sure to set only one VCR to MASTER. If no VCR
is set to MASTER, or two or more VCRs are set to
MASTER, the TIME ADJUST function will not
operate normally.
