APPENDIX C
ERROR CODES
The following errors codes may appear from time to time in the TIME counter
display. Use this reference to learn the possible cause of the error code before
attempting to contact Alesis Product Support.
dv Dew Sensor: The unit has been subjected to overly high humidity. Do not
operate the unit. Turn on the power without installing a tape. This will
allow the unit to warm up and disperse the moisture. If the “dv” message
does not go out after 2 hours contact Alesis for service.
noFo No Format: The tape is located at a point that has not been formatted.
Rewind the tape to the beginning. Press play. If the tape is formatted the
message will change to “LEAd” for 15 seconds then “dAtA” for 2 minutes
prior to the beginning of the audio section. If these messages do not appear,
the tape should be formatted.
FULL Serial Buffer Full: Not seen very often. “FULL” occurs when a slave LX20 is
slow to sync to the master LX20. The serial buffer within the micro
controller has become full of data. This could be the result of unlike versions
of software within each unit. Sometimes the problem is related to the sync
cable itself. It is recommended that only shielded and grounded cables be
used as sync cables.
Finally, this error may occur in slave machines that are playing damaged
tapes. The edges of the tape have become damaged. If only one tape is
found to cause this problem, don't use it. If the problem is seen with several
tapes, the machine should be taken in for service. Contact Alesis for
service.
Er 0 Tape Load Error: This may be a problem with the TAPE LOAD or (insert)
switch. This can be caused by labels that have been applied to the cassette
outside of the designated area. If this error message is displayed with only
one tape, the cassette may be at fault. If the message is displayed with
several tapes, with and without labels, you should contact Alesis for
service.
Er 1 – Er 4 Tape Threading: These error codes are usually related to tape threading.
Eject the tape and load it again. If this error message is displayed with
only one tape, the cassette may be at fault. If the message is displayed
with several tapes, with and without labels, you should contact Alesis for
service.
Er 5 Drum/Capstan: This error points to the head drum and capstan servos. The
problem is caused by anything creating extra resistance in the tape path, an
unevenly wound cassette or a misalligned cassette shell. You should fast
forward and rewind the cassette from end to end to flex the tape then try
the tape again. If this error message is displayed with only one tape the
cassette may be at fault. If the message is displayed with several tapes,
with and without labels, you should contact Alesis for service.
