WARNING

•Main supply:

AC 230V, 50 Hz only

•Do not remove panel covers by unscrewing them. 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.

PRECAUTIONS

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 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).

EXTERNAL CONNECTIONS

ALARM IN

You can connect an alarm switch with a resistance of 1 kohm or less or a door sensor. Connect pin q to !5or !6(ground) through the switches.

ALARM IN	GND
1	1
1	15 or	6

Note: Do not apply a voltage to pin q , !5or !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 !5or !6.

Note: Do not apply a voltage to pin t , !5or !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.
