Recording Check function
Pressing the [REC CHECK] button during recording allows you
to check the status of the recording in progress. When
activated via the corresponding function menu switch, the built-
in head cleaner automatically cleans the heads whenever
inferior picture quality is detected during Recording Check.
After cleaning, the Recording Check operation is executed
again automatically (Auto Recording Check function).

24-hour long-time recording with a 180-minute tape
Recording times are selectable from 3 hours (SP mode) and
12/24 hours (Timelapse mode). Monitor image recording for up
to one-day (24-hour) is possible with a 180-minute tape.
5
Audio monitoring
Audio signals can be recorded in the 12-hour/24-hour
Timelapse mode, as well as in the conventional 3-hour mode.
This strengthens surveillance capabilities by providing both
audio and video information.
5
Alarm recording function
When an alarm signal is input in the Timelapse Record mode,
the 3-hour mode is automatically engaged. Alarm recording
time can be selected from 5, 15, 30, 60, 120, or 180 sec., to
tape end or set manually.
An index code is automatically recorded when alarm recording
starts. Used as an alarm cue signal, this allows quick access to
alarm recording points with the Index Search function.

Time/date generator
Superimposes the year, month, date, minute and second on
the image during recording. Also allows you to use the menu
screen to display the number of alarms, alarm time, and the
number of the power failures.

Timer recording function
Two types of timer recording are available: based on the date
(up to 8 programs) or based on the day of the week.
1-1 Major Features
1 INTRODUCTION
1-2 Periodical Maintenance
This VCR incorporates precision mechanical parts which will collect dirt over time and ultimately deteriorate and wear out.
Over long periods of use, dirt and dust accumulates on the heads, drums and tape transport mechanisms. Dust which
penetrates the VCR (especially during outdoor use) also promotes the wear and deterioration of mechanical parts by causing
poor contact between tape and heads. This also prevents the VCR from maintaining video and audio quality at high levels. To
prevent wear and deterioration, clean the heads regularly using a head cleaning tape. However, because a head cleaning
tape alone cannot clean the entire tape transport mechanism, this should also be inspected periodically to prevent any
problems that could result from a sudden failure.
As replacement and adjustment of parts require advanced skills and specialized equipment, please contact the person in
charge of professional video equipment at your nearest JVC-authorized service agent for servicing.
Monitoring Usage Time
Periodic Maintenance
The total operation time reached by an ordinary home VCR
in 5 or 6 years may be reached by a professional VCR in
as few as 5 or 6 months. Therefore, it is important that the
total hours of operation be carefully monitored. An hour
meter in the on-screen display (see page 18) shows the
accumulated time. In the chart below, the hours
accumulated in each month are shown in relation to the
number of hours used per day. Times shown inside
shaded area indicate that maintenance should be
performed.
Check or replace the following mechanical parts according
to the running time.

1-3 Precautions
5
Handle the unit carefully
· Do not place anything heavy on the unit (a monitor,
etc.). A malfunction may occur.
· Do not put any foreign substance into the cassette
loading slot.
· Avoid violent shocks to the recording chassis during
transportation. Remove the cassette tape from the unit
for transportation.
5
Turn off the power to save electricity when not using the
unit.
Handling and storage place
5
Avoid using the unit in places subject to the
following conditions:
· extreme heat or cold
· strong magnetic fields (do not use a transceiver within
2 meters of this unit)
· high humidity
· dust and soil
· vibrations
· variations in temperature
5
Use this unit in horizontal (flat position) only.
5
Do not leave the unit in the Still or Record Pause
mode for a long time as this may damage the tape.
To minimize tape damage, this VCR automatically
enters the Stop mode after about 5 minutes have
passed in the Still or Record Pause mode.
Video cassette
· Only use video cassette bearing the
PAL
mark.
· To prevent accidental erasure of a recorded tape, break
the erasure prevention tab on the cassette. To use a
cassette with a broken tab, place a piece of cellophane
tape over the broken tab.
· Video cassettes cannot be used upside down.
· Leaving the tape in a partially wound condition for a long
time may damage the tape. Rewind the tape to the
beginning before storage.
Timelapse recording is performed over very long periods of time
which means that a durable tape is required.
· Use an E-180 tape or shorter.
· Do not use extended tapes (180 minutes or more such as E-240).
Erasure prevention tab
Condensation
5
Condensation occurs in the
following cases.
· When the VCR is moved from a
cold place to a warm place.
· In a room that has just been heated
or in an area directly exposed to a
cooler.
· When there is excessive humidity
5
When condensation is expected to occur
Turn the power of the VCR on before use.
5
Condensation
When cold beer is poured into a glass, water drops
appear on the glass's surface. This phenomenon is
called "condensation". When condensation occurs on
the VCR's head drum and tape guides it may damage
the tape.

1 INTRODUCTION
1-4 Daily Inspection
Although this unit has been designed for reliable operation
over a long period of time, a daily inspection is recommended
to ensure optimum performance. In particular, be sure to
check the repeat recording function on a daily basis.
4 Rewind the tape recorded the previous day for several
seconds.
5 Press the play button for playback.
6 Check that the playback picture is normal.
7 Check that the recorded date and time are correct.
· This unit includes a Recording Check function (using
the [REC CHECK] button) and an Automatic
Recording Check function for daily checking of
recording quality.
If any problems are found after inspection, turn the power off,
unplug the power plug from the AC outlet, and contact your
JVC dealer.
Inspection procedure
1 Turn on the power for all units connected to the
surveillance system.
2 Check the quality of the image shown on the monitor.
3 Check that the date and time shown on the monitor are
correct.

cassette tape.
3 [REC CHECK] button
Use to check recording.
When pressed in the Record mode, this will rewind the
tape about 4 seconds and then play back the rewound
section so that the recording quality can be checked.
After playback, the Record mode is automatically re-
engaged at the point where recording was interrupted.
· The FM level is checked during playback in Recording
Check operation to determine whether or not picture
quality is defective. If it is judged defective, the heads
are automatically cleaned. How this operation is
performed is determined by the setting of the [REC
CHECK] switch in the function menu.
When set to "MANUAL":
Head cleaning is performed once and recording
resumes.
When set "AUTO":
Head cleaning is performed once and recording is
resumed for several seconds. Then, Recording
Check operation is performed again.
If picture quality is again judged defective, head
cleaning is performed once again and "E-09" is shown
on the display to indicate that there is a problem.
Recording will continue, however.
