For the customers in the Netherlands
Voor de klanten in Nederland
Hoe u de batterijen moet verwijderen, leest u in de tekst
van deze handleiding.
Gooi de batterij niet weg maar lever deze in als klein
chemisch afval (KCA).
Für Kunden in Deutschland
Entsorgungshinweis: Bitte werfen Sie nur entladene
Batterien in die Sammelboxen beim Handel oder den
Kommunen. Entladen sind Batterien in der Regel dann,
wenn das Gerät abschaltet und signalisiert “Batterie
leer” oder nach längerer Gebrauchsdauer der Batterien
“nicht mehr einwandfrei funktioniert”. Um
sicherzugehen, kleben Sie die Batteriepole z.B. mit
einem Klebestreifen ab oder geben Sie die Batterien
einzeln in einen Plastikbeutel.

8 Function cam sensor
Detects the rotary position of the function cam.
9 T-reel table assembly rotation sensor
Detects rotation of the take-up reel table with the use of the T-reel table assembly rotation sensor. The
FG generator output of this sensor is input to the servo circuit where diameter of the remaining tape is
calculated.
0 Cassette lock sensor (switch)
Detects whether the cassette compartment assembly is locked or not.
!- Cassette ID sensor
ID1 :Tape type
Detects the tape type (Oxide or Metal).
ID2 :Tape thickness
Detects thickness of the tape that is wound in the cassette tape inserted in the set, with the
use of the tab on the rear of a cassette tape.
ID3 :Reel hub diameter
The reel hub diameter of a cassette tape is different depending on the length of a tape that
is wound in the cassette tape. The reel hub diameter sensor detects the reel hub diameter
with the use of a tab on the rear of a cassette tape.
ID4 to 6 : Tape format
Detects whether a cassette conforms to the HDCAM format or not.
!= S-reel table assembly rotation sensor
Detects rotation of the supply reel table with the use of the S-reel table assembly rotation sensor. The

1-8.Removing and Reinstalling the
Flexible Card Wires
Type-B
This unit uses two types of flexible card wire.
m
. Life of flexible card wire will be significantly shortened if it
is folded. Be very careful not to fold the flexible card wire.
.
When a flexible card wire is disconnected, check if it has
peeling-off or scratch on the tin plated contact of the
connector. If the copper plating of the base material
exposes due to wear of the tin plated contact of the
connector, replace it with the new flexible card wire.
Type-A
Removal
1. Open the connector latch in the direction of arrow A to
release the lock.
2.
Remove the flexible card wire in the direction of arrow B.

3. Slide the cam plate (A) of the right side of the cassette
compartment assembly in the direction of the arrow as
far as it can go.
4. Hold the cassette compartment assembly at the position
shown in the illustration and insert the chassis so that
the two cassette guide pins enter into the round hole of
the stage.
At this moment, confirm that the white roller at the
other end of the joint arm that is adjusted of its position
at step 1, enters into the notch of the cam plate (A) on
the right side.
5. Press the lid arm (L) of the cassette compartment
assembly and check to see that the stage can move up
and down smoothly. If the stage does not move up and
down smoothly, check above procedure starting from
