Entering Test Mode
The MZ-R30 is put into test mode by placing 24 kiloOhms between pin 2
and 4 of the remote control connector when the unit is off (counting
from left to right, with the headphone jack on the left).
Test Mode
Display alternates between:
- "Ver 01.60" version notice (of control logic?)
- All display elements on
- All display elements off
Functions:
- Keeping PAUSE pressed pauses this alternation.
- Pressing |<< brings unit in ASSY Mode
- Pressing >>| brings unit in SERVO Mode
ASSY Mode
Display says:
Functions:
- Pressing STOP will move head to track 0 and back to track 40 (?).
-
Display shows 00 FF, then 40 FF again, while doing so.
- Pressing PLAY will do a magneto-optical test run, thereby OVERWRITING
the inserted MiniDisc with a test signal.
- Text Display shows "MO RUN" during this test.
- MZ-R30 mechanisms make a noisy sound.
- Display shows numbers 31 to 38, then 61, then 82, both for a longer
time,
then 39 short, 82 long, d0, 42, 43, and stops again at 00.
- Display then shows "MOmode OK" or MOmode NG" to indicate success or
failure.
SERVO Mode
Text display shows "SERVO".
Functions:
- |<< and >>| can be used to move the head left and right. WARNING: Don't
force crossing begin and end boundaries.
- STOP and PLAY will traverse through a list of parameters. STOP decreases
the parameter number, PLAY increases it.
- Display shows: "XX YY"
- XX is the parameter number
- YY is a value, and is displayed in one of 3 ways:
- not at all
- statically, which means a read-only value (?)
- flashing, which means you can use the VOLUME DOWN and UP buttons to
adjust the parameter.
NOTE! Write down each XX YY pair before you start playing around.
My unit showed these values: (<YY> means flashing, i.e. adjustable value)
