Precautions
On safety
•Operate the unit on 220 - 240 V AC, 50 Hz only.
•The nameplate indicating operating voltage, power
consumption, etc., is located on the rear of the unit.
•Should any solid object or liquid fall into the cabinet,
turn off the power, unplug the unit and have it
checked by qualified personnel before operating it
any further.
•Do not drop or place heavy objects on the power
cord. If the power cord is damaged, turn off the
power immediately. It is dangerous to use the unit
with a damaged power cord.
•Connect the power cord to the wall AC outlet.
For connecting the power source, see “Connecting a
Camera, Monitor and Microphone”on page 9.
•Unplug the unit from the wall outlet if it is not to be
used for several days or more.
•Disconnect the power cord from the wall AC outlet
by grasping the plug, not by pulling the cord.
On installation
•Do not place a heavy object on the unit.
•Allow adequate air circulation to prevent internal heat
build-up.
Do not place the unit on surfaces (rugs, blankets, etc.)
or near materials (curtains, draperies) that may block
the ventilation slots.
•Do not install the unit in a location near heat sources
such as radiators or air ducts.
•Place the unit to avoid direct sunlight.
•Do not install the unit in a place subject to
mechanical vibration or shock.
•Do not put magnetic objects close to the unit and
cassette tape. Magnetic fields may affect the color
reproduction of the unit and cause distortion.
•The unit is designed for operation in a horizontal
position.
Do not install it in an inclined position.
On operation
When the unit is not in use, turn the power off to
conserve energy and to extend its life.
On moisture condensation
If the unit is brought directly from a cold to a warm
location, moisture may condense on the video head
drum. In this condition, the tape may adhere to the
head drum and cause serious damage to the head. To
avoid damage caused by moisture condensation, be
sure not to leave a cassette inside the compartment
when the unit will not be used. If moisture
condensation is present, the “dddd”indicator flashes in
the display window and the
unit will not operate. When
the “dddd”indicator
disappears, you can operate
the unit.
On video cassettes
Remove and store video cassettes after recording or
playback.
On cleaning
As a safety precaution, unplug the unit before cleaning
it.
•To keep the unit looking brand-new, periodically
clean it with a mild detergent solution. Never use
strong solvents such as thinner or benzine, or abrasive
cleaners since they will damage the cabinet.
When cleaning, keep liquid away from electrical
contacts and connectors.
•When there is a buildup of dust on air vents, use a
vacuum cleaner to remove it.

5
On repacking
•Before repacking, disconnect all cables and
connecting cords.
•Do not throw away the carton and packing materials.
They make an ideal container with which to transport
the unit. When shipping the unit to another location,
repack it.
On transportation
When transporting the unit, protect it from vibration
and impact.
If you have any questions about this unit, contact your
authorized Sony dealer.
Backup function
•This unit is equipped with a backup battery (lithium
battery) to maintain the clock settings. When the
unit is used under normal conditions, the backup
battery is recharged. The battery is fully recharged
after a minimum of about 30 hours, and will
maintain the clock settings for up to about 30 days.
Note
The settings may not be maintained properly if the
backup battery has been recharged for less than 30 hours
when the power goes off.
•To replace the backup battery (lithium battery),
contact your Sony dealer.

Features
Field recording/field playback
Because single fields can be recorded one by one in
time lapse mode and all fields can be viewed
separately during playback, you can record more
information.
Various recording functions
•Repeat recording: When the tape reaches the end,
the VCR rewinds the tape and starts recording again
from the beginning of the tape.
•Timer recording: You can set the timer on daily
recording or weekly recording. You can also record
by an external signal input.
•Alarm recording: If an externally connected alarm
sensor is triggered, you can make a complete
recording of the situation that triggered the alarm.
Mode settings on monitor
You can set the modes for all functions, such as the
internal timer setting, the alarm recording mode
settings, etc., on the monitor.
Series recording function
This function permits long-term continuous recording
using two or more time lapse VCRs.
Multiple recording modes
The time lapse intervals for recording can be set in 4
steps. At the longest interval setting, available
recording time is a full 72 hours with one 180-minute
tape.
RS-232C/RS-485 interface
By installing an optional SVT-RS100 Computer
Interface Board, you can control this VCR from a
personal computer or a controller via an RS-232C or
RS-485 interface.
Recording the alarm data at the top of the tape
You can set to record up to 100 alarm data (count, date
and time) on the beginning of the tape. These data can
be displayed on the monitor screen.
VIDEO LOSS detection
If an input signal is interrupted while recording or
recording pause, the VCR will give a warning on the
display window of the monitor.
Clog detection
The VCR always checks that the video signal is
recorded without problem (in time lapse mode only).
If the recording cannot be made properly because the
recording head has become clogged, the VCR will give
a warning.
Time and date retrieval function
Because this unit uses a high-performance VASS,
recordings made in time lapse mode can be searched
by date and time (hour and minute up to every 10
minutes), a valuable type of search function in time
lapse VCRs.
Forward/reverse field advance
This VCR offers improved search functions with the
ability to move both forwards and backwards between
fields.
Real time display
The real time can be displayed even in time lapse
mode.
Security lock
To guard against operation errors, this VCR locks all
of the buttons.
Monitoring the recording condition
You can check the recorded image during recording by
pressing a single button.
Checking the tape threading
To ensure correct operation, the VCR automatically
checks the tape threading whenever you insert a tape.
Other features
•Fast-forward and rewind with high speed
•Quick-start mechanism which makes the time to start
recording shorter
•Power saving mode which turns off the display
window
•The number of times the tape has been recorded will
be recorded on the beginning of the tape and
displayed in the display window

Notes
•Whenever you insert a tape and first start recording,
Adaptive Picture Control (APC) automatically improves
recording quality by adjusting the VCR to the condition of
the video heads and tape. To activate this function, set
APC in the GENERAL SET menu to ON (see page 39).
There is about a 10-second delay before the VCR actually
starts recording when REC zis pressed.
•This VCR is provided with a clog detection function. In

terminal. In this case, stop recording immediately and
check the VCR.
•If ALARM DATA REC on the ALARM SET menu and/or
TAPE USED COUNT on the GENERAL SET menu is set
to ON, the VCR will rewind the tape and recording will
start from the beginning of the tape. While the VCR is
rewinding the tape, “<AL DATA REC>” and/or “<T-
USED COUNT>” appears on the monitor screen.
•While both TAPE USED COUNT and ALARM DATA
lists are being recorded, the REC indicator in the display
window lights up (in this case, the REC indicator goes out
momentarily between TAPE USED COUNT and ALARM
DATA lists).
•In the recording or recording pause mode, if the VIDEO
input signal interrupted, the screen of the monitor becomes
blue and “VIDEO LOSS” appears on the monitor.
