SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly transis-
tors, that were installed during a previous repair. Point them
out to the customer and recommend their replacement.
SAFETY-RELATED COMPONENT WARNING!!
COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED
LINE WITH MARK 0 ON THE SCHEMATIC DIAGRAMS
AND IN THE PARTS LIST ARE CRITICAL TO SAFE
OPERATION. REPLACE THESE COMPONENTS WITH
SONY PARTS WHOSE PART NUMBERS APPEAR AS
SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.
4. Look for parts which, though functioning, show obvious signs
of deterioration. Point them out to the customer and recommend their replacement.
5. Check the B+ voltage to see it is at the values specified.

About Adaptive Picture Control (APC)
Adaptive Picture Control (APC) automatically improves recording and
playback quality by adjusting the unit to the condition of the video heads
and tape.
APC playback
The APC function automatically works on all types of tapes, including rental
tapes and tapes that were not recorded with APC.
APC recording
Whenever you insert a tape and start recording, the unit adjusts to the tape
using the APC function. This adjustment is retained until the tape is ejected.
Tip
• Adjust the picture using V/v TRACKING NORMAL/SLOW/STILL ADJUST if:
– streaks appear while playing in slow motion
– the picture shakes during pause.
Notes
• The auto tracking function works automatically when you play back a tape just
after inserting it.
• There is a delay of a few seconds before the unit actually starts recording while the
unit analyzes the tape. To avoid the delay, first set the unit to recording pause and
press z REC to have the unit analyze the tape. After ten seconds, press X PAUSE to
start recording immediately. If you press X PAUSE
before ten seconds, the APC
function is canceled.
• Sufficient picture quality may not be obtained when playing back tapes recorded on
another VCR or tapes in poor condition.
• When a tape recorded with the copyguard system is played back, intermittent
distortion may appear in the upper portion of the picture. However, this is not a
malfunction of the unit.

How to make a Synchronized recording
SYNCHRO REC
1
Set the timer on the equipment to the time of the program you want to
record, then turn the equipment off.
2
Insert a tape with its safety tab in place. Make sure the tape is longer
than the total recording time.
3
Set TAPE SPEED to select the tape speed, SP or EP.
4
Hold SYNCHRO REC down for more than two seconds.
The SYNCHRO REC button lights up and the unit stands by for
recording.
The unit automatically turns on and starts recording when it receives audio/
video signals from the connected equipment.
To cancel the Synchronized recording
Press SYNCHRO REC so that the button’s light turns off.
To stop recording
Press x STOP while recording.
The unit automatically stops recording when the tape reaches the end or
when the other equipment stops transmitting the audio/video signals.
Notes
• Some TVs or other equipment automatically turn off in a certain amount of time if
you do not operate it after it turns on with the timer. In this case the Synchronized
Recording also stops automatically.
• The Synchronized Recording starts and stops according to the signals from the
connected equipment. Refer also to the instruction manual of the connected
equipment for information about its timer function.
• Some equipment keeps transmitting signals even though the power is off. In this
case, the Synchronized Recording feature does not work because the unit will not be
able to know when to start recording.
