——
RECORD/PLAYBACK/
TRANSFER Changing Mechanism
When MODE SELECTOR KNOB (B) is set
to Record position (a), Playback position
(b), or Transfer position (c) (Fig. 1), Knob
(B) actuates Switch Lever (D) to (a”), (b”),
or (c”) position respectively and SW104,'
105, or 106 is set to Record, Playback, or
Transfer position.
Adjustment Procedure
a) Remove amplifier from chassis (leave
wires between amplifier and chassis
connected).
b) Play back a 250Hz or a 1000 Hz
frequency cartridge or cassette tape
(not a reel tape). Tum up volume so
that both VU Meters indicate 0 VU.
c) Return Mode Selector Knob (B) very
slowly from Transfer Position (c) to
Playback position (b). Just as Knob
(B) is returning perfectly to position
(b) (about 1/2 mm before perfected
position), both VU Meters should indi-
cate OVU and sound should come
from speakers.
d) Similarly, when Knob (B) is returned
from position (a) to position (b) in the
same way, both VU Meters should
indicate OVU and speakers should
emit sound instantaneously.
e) In case the operation in items c) and
d) above are not indentical, loosen
screw (G) and adjust the position of
Knob (B).
f) If this adjustment is not correct, some-
times recording or playback cannot be
accomplished, or the operation of one
channel is faulty.

(A) Operation of Switch Changing Mechanism
(B)
When System Selector Knob (A) is set to
Reel position (1), Cassette position (2), or
Cartridge position (3), (Fig. 1), Knob (A)
actuates Switch Lever (E) to (1), (2”), or
(3") position respectively, and SW-101,
102, or 103 is set to Reel, Cassette, or
Cartridge position.
Adjustment Procedure
a) After adjustment (1) has been com-
pleted, place a pre-recorded reel, cas-
ette, and cartridge tape on recorder for
playback. Turn Lever (A) to each of
the (1), (2), and (3’) positions and
confirm that playback is effected
respectively.
b) Return Knob (A) very ‘slowly from
(1) (Reel position), to (2') (Cassette
position). Just as the lever is returning
perfectly to (2') position (about
1/2mm before perfected position),
the sound from reel playback should
be completely cut and playback of
cassette only should be effected.
c) Similarly, when Knob (A) is returned
from (3') position to (2’) position,
the cartridge sound should be com-
pletely cut and playback of cassette
only should be effected.
d) If playback is not effected as outlined
in items b) and c) above, loosen screw
(H) and adjust the position of Knob
(A).
e) Confirm that the microswitch operates
when Knob (A) is switched to
positions (1'), (2'), and (3’).
