1 INTRODUCTION
1-3 Precautions
Video cassette
Erasure prevention tab
Timelapse recording is performed over very
long periods of time which means that a
durable tape is required.
When using VHS tapes, do not use tapes with
recording times of more than 120 minutes
(T-160/T-180 etc.).
For best results, use a T-120 tape.
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/playback
function on a daily basis.
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.
8
• Only use video cassette bearing the
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.
To obtain the best picture quality, use an HG (high
grade) tape (a JVC cassette is recommended).
Degradation of picture quality may result with some
types of tape. Make a test recording before
performing any important recording to check the
picture quality.
3
Check that the date and time shown on the monitor are
correct.
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.
5 This unit includes a Recording Check function (using the
[REC CHECK] button). Use these features to quickly
check recording quality on a daily basis.
If any problems are found after inspection, turn the
power off, unplug the power plug from the AC outlet,
and contact your JVC dealer.
