see (& download) a user's manual for the DCC900 (1.15 MB, Adobe .pdf format).
Note that the actual user's manual is in many different languages, but I have
only scanned the English part for this file.
Below is an exploded view of the DCC900

To put the DCC900 into service mode,
first ensure that there is a DCC tape in the DCC900. Service mode can be entered
without a DCC tape in the recorder, but in order to view or display values,
there must be a DCC tape in the recorder when GO PLAY MODE is displayed, at
which time PLAY should be pressed. At this time the values can be
viewed/changed.
After inserting a DCC tape, do the
following:
-
turn the power off.
-
Press and hold the PLAY and STOP
buttons together, then turn the power on.
-
The DCC900's front display panel
will scroll SERVICE MODE
-
Next, see the row in the table below
for "0". The DCC900 will proceed to display the scrolling list of
characters as shown.
-
To change to each row as shown,
press the TIME key.
-
To view/change values (such as to
change the eye channel), press PLAY when GO PLAY MODE is displayed, then
view/change as required.
-
To exit service mode, press the
COUNTER RESET key.
