SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety checks before releasing the set to the
customer :
Check the metal trim, “metallized” knobs, screws, and all
other exposed metal parts for AC leakage. Check leakage
as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth
ground and from all exposed metal parts to any exposed
metal part having a return to chassis, must not exceed 0.5
mA (500 microampers). Leakage current can be measured
by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229
or RCA WT-540A. Follow the manufacturers’
instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means
of a VOM or battery-operated AC voltmeter. The
“limit” indication is 0.75 V, so analog meters must
have an accurate low-voltage scale. The Simpson 250
and Sanwa SH-63Trd are examples of a passive VOM
that is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are suitable. (See

7. RACK MOUNTING
The unit can be mounted in a 19-inch standard rack.
It is recommended to use the following kit.
Rack Mount Kit : RMM-130 (optional accessory)
or
RACK-MOUNT SLIDES : MODEL 305
slide length 22 inch
(ACCURIDE)
Note for rack mounting :
.When several VTRs are mounted in a rack, it is recommended to
install a fan for ventilation. Good air circulation is essential to
prevent internal heat build-up in a rack (+5 dC to +40 dC must be
met for all units).
.Never remove an upper panel and lower panel during rack
mounting.
.Be sure to secure the rack to the floor to avoid accidents when a
unit is pulled out.
.Connect long enough cables on the connector panel, considering
that the unit is pulled out.
.This equipment can use with two tiers.
But with three tiers and more, keep the spaces between the each
VTRs in the rack 1 unit (about 44 mm) or more.
1. Remove the four screws on right and left side panels.
And install the Inner Members of the rails to the right and left
side panels with the screws removed.
2. Install the Outer Member Brackets of the slide rails to the rack.
Adjust the distance from the edge of the slide rail to the outside
of the rack so that it meets the required specification.

3. Remove the two screws (B 4x8) on the right and left side
panels. (Be careful not to lose these four screws.)
4. Install the L-angles to the holes described in step 3 with the
supplied screws (PSW 4x16) in RMM-130 for these L-angles.
Note: Never use screws PSW 4x16 to install the right and left
side panels without L-angles. Be sure to install the panels
with the screws B 4x8 removed in step 3. Screws for L-
angles are longer than the side panels. Therefore, using the
screws PSW 4x16 may cause trouble in the unit.

8. CONNECTION OF EDITING EQUIPMENT, AND INPUT/OUTPUT SIGNALS OF CONNECTORS
8-1. Connection of Editing Equipment
Connection for Digital Non-Linear Editing System
The digital non-linear editing system can be configured by connecting between DSR-80/80P/60/60P and the edit station ES-7.
Use of the QSDI interface (optional board as to DSR-60/60P) enables transfer of the compressed data such as video, audio and timecode from
DSR-80/80P/60/60P to ES-7.
DSR-80/80P/60/60P supports the ClipLink function. The index picture which is recorded on tape and the ClipLink log data which is stored
in the cassette memory can be transferred immediately to ES-7.
.Refer to “ClipLink™Guide”supplied with the unit for general description of ClipLink functions.
Connection example of digital non-linear editing system when DSR-80/80P is used as a recorder and DSR-60/60P as a player, is shown
below.
.Refer to the Operating Instructions supplied with ES-7 for the connection procedure of the peripheral equipment (such as control panel
ESBK-7011, disk unit ESBK-7045, etc.,) of ES-7.
Note : In this connection example, DSR-80/80P/60/60P is equipped with the optional board DSBK-100/100P/110/110P/
120/120P/130/130P.

Note : When the QSDI interface is used for the connection, monitor of the JOG audio cannot be switched to the recorder
monitor even through recorder enters the E-E mode. Therefore, monitor the JOG audio at the player side.
About the reference video signal
The reference video signal which is synchronized with the video signal in use, is necessary and must be input to the REF. VIDEO IN
connector for analog signal editing in order that the built-in TBC works correctly and the stable picture and audio are obtained.

Connection for A/B Roll Editing System
Connection example of the A/B roll editing system using a recorder and two players is shown below.
In this example, DSR-80/80P is used as recorder, DSR-60/60P is used as player-1 and an analog betacam video cassette player UVW-1600/
1600P is used as player-2. When you require the completed tape (the tape in which complete packaged program is stored) in the betacam
format, use a betacam VTR as recorder.
The following system configuration diagram is shown with the main emphasis placed on the signal flow. Refer to the following pages for
actual connection procedure and setting of DSR-80/80P (recorder).
