1 INTRODUCTION

1-1 Major Features

5240-hour long-time recording with a 120-minute tape Recording times are selectable from 6 hours (EP mode) and L18/L30/48/72/96/120/168/240 hours (Timelapse mode). Monitor image recording for up to 240 hours is possible with a 120-minute tape.

5Audio monitoring

Audio signals can be recorded in the 18-hour/30-hour Timelapse mode, as well as in the conventional 6-hour mode. This strengthens surveillance capabilities by providing both audio and video information.

5Alarm recording function

When an alarm signal is input in the Timelapse Record mode, the 6-hour (EP), 18-hour or 30-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.

5Sensor recording

Whenever an alarm signal is input in the Stop mode, the Record mode is automatically engaged.

5Time/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.

5Timer 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.

5Recording 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).

5Operation lock system

To prevent accidental or deliberate interference with VCR operation, the operation lock system is provided.

5Warning function

Error indications are shown on the front panel display.

5Power-off video throughput function

Even when the power is off, the camera's EE input can be output from the VCR.

5Camera switching signal output terminal

5Automatic re-start of recording after a power failure

5Digital hour meter display

5Repeat recording/series recording function

5Recording control with external activation signal

5Alarm recording, tape end and warning electronic buzzer

5Summer time compensation function

5Wired remote control (optional)

5RS-232C control (with optional SA-K97U RS-232C interface board installed)

The SR-9168U can be controlled via a personal computer. Operation status can be monitored on the computer.

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

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 16) 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.
