1. T0Remove Cassette Lid

1) While pressing hard the arrow-indicated parts (left and right)
in the directions indicated by the respective arrow marks in
figure, pull out the cassettelid for removal. (Refer to Fig. 1)

Fig.1

2. To Install Cassette Lid

1) Refering to figure, align the pawls of the cassettelid properly
with respective guides provided on the mechanism panel and
insert them into guides securely.

2) While pressingthe parts (1) of the cassettelid in the directions
indicated by the respective arrow marks, push the entire
cassette lid toward the mechanism panel until it is securely
installed in place. (Refer to Fig. 2)

3. To Remove Back Cover

MECHANIOAL SECTION

1. Review Timing Adjustment

During review operation, the pinch roller and play idler should
separate either simultaneously, or the pinch roller separates
first.

Adjustment
During play operation, depress the REW button. Adjust by
bending the operating tab forward or rearward to obtain the
abovetiming. (Refer to Fig. 11)

Operating tab

2. Pause Timing Adjustment

In pauseoperation, the pinch roller, play idler and leaf switch

all separate sirnultaneouslv, or the pinch roller separatesfirst.

Adjustment

During play operation, adjust by bending the operating tab

forward or rearward. (Reter to Fig. 12)
