The test runs automatically. The display shows “r. nn
r. nnr. nn
r. nn” symbols. where “r.
r.r.
r.” means “RAM” and “nn
nnnn
nn” is number of
block of RAM cells under testing procedure. During the test, block numbers 1 to 32 are displayed sequentially.
Each of these 32 blocks of RAM cells has size 4096 byte. After whole area of RAM cells are checked successfully,
the display shows “r.ok
r.okr.ok
r.ok” symbols for approx. one second and then the device continues to next test
automatically.
If any defective memory cell is detected during the RAM test, display shows “r. E. n
r. E. nr. E. n
r. E. n” symbols (RAM Error) where
“n
nn
n” is number of the error (see table 2). In this case, continue to next test occurs after button is pressed.

.6. Test of MIDI inputs and outputs
Standard MIDI cable (with DIN 41524 connectors on both ends) is necessary for execution of this testing
routine. Individual MIDI inputs and outputs of the device will be interconnected with help of this cable.
The test is indicated by symbol “M.
M.M.
M.” on the display – it means “MIDI”.
Until no MIDI input is connected with no MIDI output, symbols “--
----
--“ is shown on the display. Connection of
arbitrary MIDI input with arbitrary MIDI output is indicated by symbols of two characters. First of them
indicates used MIDI output (“i
iii” = INSTRUMENT-OUT, “c
cc
c” = CONTROLLER-OUT) and the second indicates used
MIDI input (“i
iii” = INSTRUMENT-IN, “c
cc
c” = CONTROLLER-IN).
If symbol “--
----
--“ is still displayed or if symbol “-
--
-?
??
?” is displayed after a MIDI input is interconnected with a MIDI
output, used MIDI input or MIDI output respectively is not working correctly.
For continue to next test, RESET button need to be pressed.

End” symbols and the device stops all operations. Now,
you can disconnect power supply adapter from the device.
If no error occurs during testing procedures, the device is fully functional and it should to work with MIDI
system correctly.
If any hardware malfunction was detected during testing procedures, the device must be repaired in specialized
workshop.
