Data Check
One of the features of the DX is a data check routine that runs automatically when the
unit is turned on and when leaving the Data Storage mode. The data check routine
looks at each sequence and song to make sure that it is properly configured in
memory.
Bad Sequences can appear in the DX'
s memory several ways
, by loading a cassette
tape with more than 2200 notes from a OMX into a OX
, for example. If there is ilegal
information in a sequence
, the Data Check routine wil alternately flash the Sequence
Number followed by "
dEL?" and the ERASE key will light. If a bad Song is discovered
the Song key will light up as well. Press ERASE to delete the bad Sequence. If any
other key is pressed the sequence in question will not be deleted
, and it wil look
for
more bad Sequences.
After checking all of the sequences and songs the OX
wil return
to normal operation.
However
, if any bad sequences or songs remain in the memory (ones that you
declined to delete), the display wil flash "
bAd" and the unit wil "
beep:'
. Note: Be careful
when working with bad sequences (ones that you didn
t delete). In
particular
, any attempt to alter a bad sequence by Recordin
g, Erasing, etc. wil almost
always cause the DX to crash. See "
If Your DX Gets Lost:
Ram Check
Besides the above mentioned Data Check routine
, a Ram Check routine is run when
the OX is turned on. This routine checks for random data in the memory. Random data
of this type can result from a loss of power to the memory, for example. If the data in
the memory is bad
, the OX wil "
beep
" and display "
bAd;' followed by a "
CLa" mes-
sage while the ERASE key lights up. Pressing the ERASE key erases everyhing in
memory and resets the Edit Parameters to their default values.
If Your DX Gets Lost
Under certain circumstances many computer based products can lock up. In particu-
lar. if the message "
Err " appears unexpectedly, the OX has gotten lost. In this
instance clearing memory will solve the lock up problem
, but you
wil lose
aU your work
too! If this condition ever happens
, we
STRONGL Y ADVISE
recording your memory on
a cassette. Immediately enable cassette mode on the back panel and follow the direc-
tions In the CASSETTE INTERFACE section of this manual. When your memory Is
safely on cassette
, proceed as follows: Press any key and the OX will attempt to pro-
ceed. It wil usually succeed
, but wil occasionally lock up once again. If it locks up
again
, even turning the power off and then on again may not help.
When All Else Fails
If your OX does not respond to the above methods of resuscitation
, turn the power off.
Then while holding the ERASE key, turn the power on again. This Failsafe Erase Mode
wil clear memory and reset the Edit Parameters to t!1eir default values.
