NOTES:

      #1       Error 90 is a common error due to different boot-up routines,
              usually not of great importance if re-booting the machine clears the message.
              IF error repeats, try spray cleaning the connector to the Serial Board in the Transport Card Cage.
 
 
      #2      Dip Switches 1-5 inside the Remote on CPU PCB will defeat indication of error codes 91 - 99
             Error 90 cannot be turned off this way.


             To begin a Full Machine Function Test, Hold down all five transport buttons on the machine and then press
             "Search Zero" then release.     After a short period of time, the machine will perform a Full-Function test.
             To exit test mode press CLEAR.     Tape Control will display "-A.err--" until the TIME/IPS/% button is pressed.

 
             To view the TRANSPORT Software Version:     Turn ON the machine while pressing the TRANSPORT's "STOP" switch.
             Recorder will display software number and version on Transport tape counter.
 
             To view the REMOTE's Software Version:     Turn ON the machine while pressing the REMOTE's "STOP" switch.
             Recorder will display the REMOTE's software version on the Remote's tape counter
