Notes
• To play a tape in stereo, you must use the A/V connections.
• When you play a tape recorded in monaural, the sound is heard in monaural

regardless of the AUDIO MONITOR setting.

• If the AUDIO MONITOR button does not function, check that AUDIO MIX in the

ADVANCED OPTIONS menu is set to OFF.

The VCR records sound onto two separate tracks.  Hi-fi audio is recorded
onto the main track along with the picture.  Monaural sound  is recorded
onto the normal audio track along the edge of the tape.

Additional Operations

The VCR marks the tape with an index
signal at the point where each recording
begins.  Use these signals as references
to find a specific recording.  The VCR
can search up to 99 index signals ahead
of or behind the current position.

Insert an indexed tape into the VCR.

Press 

./> INDEX SEARCH repeatedly to specify how many

index signals ahead or behind you want to search:

• To search ahead, press 

> INDEX

SEARCH.

. INDEX

SEARCH.

The VCR starts searching and the index
number on the TV screen counts down to
zero.  Playback starts automatically from
that point.

Press 

x STOP.

Note
• No index signal will be added when recording starts from recording pause.

However, an index signal will be marked if you change the program position

Although the VCR automatically adjusts the tracking when playing a tape
(the   indicator flashes in the display window, then goes off), distortion
may occur if the tape was recorded in poor condition.  In this case, manually
adjust the tracking.

Press the TRACKING +/– buttons to display
the tracking meter.  The distortion should
disappear as you press one of the two buttons
(the   indicator lights up).  To resume
automatic tracking adjustment, eject the tape
and reinsert it.

The Reality Regenerator function automatically restores the picture to its
original quality during playback.

To use the Reality Regenerator
function, press REALITY
REGENERATOR.  The REALITY
REGENERATOR indicator lights up.

To turn it off, press REALITY
REGENERATOR.  The REALITY
REGENERATOR indicator goes off.

Additional Operations

The Adaptive Picture Control (APC) function automatically improves
recording and playback quality by adjusting the VCR to the condition of the
video heads and tape.  To maintain better picture quality, we recommend
that you set APC to ON in the ADVANCED OPTIONS menu (with the APC
indicator in the display window lit).  For details, see page 33.

The APC function automatically works on all types of tapes, including rental
tapes and tapes that were not recorded with APC.

Whenever you insert a tape and first start recording, the VCR adjusts to the
tape using the APC function (the APC indicator flashes rapidly).  This
adjustment is retained until the tape is ejected.

Notes
• The automatic tracking adjustment cannot be guaranteed to work with tapes

recorded in the LP mode on other VCRs.

• The APC function does not work if the tape speed is automatically changed from

the SP to EP mode during a timer recording when AUTO TAPE SPEED is set to ON
in the ADVANCED OPTIONS menu, unless the tape has been recorded in the EP
mode with the APC function.

• There is a delay of about ten seconds before the VCR actually starts recording while

the VCR analyzes the tape.  To avoid the delay, first set the VCR to recording pause
(the APC indicator flashes slowly) and press 

z REC to have the VCR analyze the

tape (the APC indicator flashes rapidly).  After the APC indicator stops flashing,
press 

X PAUSE to start recording immediately.

If you want to start recording quickly without using the APC function, first set the
VCR to recording pause (the APC indicator flashes slowly) and press 

X PAUSE to

start recording.
