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 XT is

 

slow to sync to the master XT. 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.
