Replacement of the mechanism chassis unit is recommended for the 12,000 h maintenance.
“C
” : Perform cleaning.
“R
” : Assembly subject to exchange.
“Y
” : The timing of replacement with Cleaning Arm Unit,
either 1000 hours or 1 year as timing come earlier.
“G
” : At the time of replacement, wipe off the old grease
and apply new grease. (Molytone Grease)
“L
” : Lubrication is necessary.
“IM
” : Included in the mechanical chassis unit
when the mechanical chassis unit is not replaced,
replacement as a single part is required.

The Hours of use indicates the cylinder rotation time
(DRUM RUN).
The maintenance execution time shown in the chart
is recommendation for standard maintenance
execution.
This is not the life of the various parts.
The life is influenced by temperature, humidity, dust,
etc.

6. Emergency Eject
If the cassette cannot be ejected by pressing the
EJECT button, use a screwdriver or similar tool to
press and turn the EMERGENCY screw. This enables
the cassette to be removed.
1.  Turn the power OFF.
2.  Remove the rubber cap where shown in the figure.
Insert a Phillips head screwdriver into the cross-
shaped part of the EMERGENCY screw (red).
3.  While pushing in with the screwdriver, turn the
EMERGENCY screw counterclockwise until the
tape is ejected.
·This screw needs to be rotated through about 20
turns after the first turn until the unloading can
be started.
·This screw needs to be rotated through about 90
turns after the first turn until the tape is ejected.4.  Remove the cassette.
5.  Return the rubber cap to its original position.
< Notes >
·Do not turn the EMERGENCY screw except in an
emergency.
·Do not turn the screw clockwise. Stop turning the
screw as soon as the tape is ejected. Otherwise, the
mechanism may be damaged.
·After the tape is ejected, the cassette holder will not
be locked even when it is closed. Be sure to turn the
power off and turn it back on to reset the
mechanism’s operation, and then close the cassette
holder.
·A clicking sound will be heard while the
EMERGENCY screw is been turning: this sound is
made by the reel drive operation. Therefore it isnt
indication of a malfunction.
