Hote 1: When the record/playback head has been
veplaced, tighten screws (A), (8), (C) shown
in Fig.4-7 until they stop, then slacken them
by 1-1/2 turns before starting alignment
Note 2: When the erase head has been replaced,
install 't as shown in Fig. 4-8.
1, Altach head position alignment jigs A and B, then
set the deck to the play mode.
2, Fit Jig B on the tape guide of the record/playback
head as shown in Fig.4-5, then align the height with
screw (A) as shown in Fig. 4-7.
3. Fit jig B to the head as shown in Fig.4-6 to check
its tilt and align it using scrwes (B) and (C) shown
in Fig.4-7.
Then align the height again with screw (A)
4, Repeat alignments in procedure 2 and 3 two or three
times to align height and tilt. ( When adjusted to
the standard height, the head should be under the
tape guide.)
5. Fit jig 8 to the tape guide of the left pinch roller
and align the height with nut (E).. ( The standard
height is above the tape guide.
6. Phay test tape HIT-902, and adjust nut (£) so that
the lower edge of the tape guide of the record/play-
back head is in contact with the tape edge, but the
tape is not curted
7, Adjust the azimuth of the playback head with screw
(C) shown in Fig. 4-7 according to item §-3 ( on
page 18 ). If the screw is rotated by half a turn
or more, turn screw (A) and (B) by the same amount
then align from item 6 to correct the height of the
tape guide of the record/playback head
8. After alignment is complete, check the tape does no
curl over the tape guide by repeating play and stop
operations

Note: In both FHO and REV play odes, these measurements
should be made at the beginnig, middie and the end
of the tape.
4-6-1 PLAYBACK HETHOD
1, Connect a wow and flutter meter to the deck as shown
in Fig.4-11.
2. Load a TEAC HIT-111 test tape or equivalent and, in
FWD and REV directions, play it to measure the wow
and flutter value.
3. Specifications are shown below.
0, 055% WRHS (R-9000)
0.050% WRHS (¥-9000)
4-6-2 RECDRD/PLAYBACK HETHOD
Note: When measuring with this method, the recorded
section should be piayed back repeatedly to obtain
an average value.
Be careful not to read the meter for those parts
of the tape in which wow and flutter components
in recording and playback cancel each other.
4. Load a blank TEAC MTT-5511 test tape or equivalent
and record a 3,000 Hz signal in FHD (REV) directon.
5. Rewind (fast forward) the rape to the begianigng of
the recorded secton, and play it in the FHD (REV)
diraection.
6. The wow and fiutter should not be more than specified.

4-8 VOLTAGE CONVERSION
(FOR GENERAL EXPORT MODELS)
ALWAYS DISCONNECT THE POWER LINE CORD BEFORE MAKING
THESE CHANGES.
1. Locate the voltage selector on the rear pane! of the
deck as shown in the illustration
2, Using a regular screwdriver, Curn the selector unti
the numerals corresponding to the voitage require-
ments of your area appear

PL ARORw
5-1 PRECAUTIONS
1. Since this deck haS an automatic tape selector, be
sure ta use test tapes that have tape position
detecting holes.
2. Before performing adjustments and checks, clean and
demagnetize the entire tape path,.then check tape
motion condition. ;
3. Make sure Che deck is properly set for the voltage
in your locality
4. In general, adjustments and checks are made in the
order of L-ch then R-ch.
Double REF: Nos, such aS R129/R229 indicate L-ch/
R-ch.
5. The AC voltmeter used in the procedures aust have
an input impedance of 1 H& or nore:
6. 0 dB is referenced to 0.775 Vv.
