2.General:When inserting the ADU in the SF-2020, there was a danger of the lock of the machine
becoming loose, causing the possibility of problems of clam shell opening. As a
measure to alleviate this problem, a change has been carried out in the diameter of the
lock lever spring, to improve the load of the spring. The change has also been carried
out in the springs of the other models listed above to establish interchangeability.
3.Action: ∗1SF-1120/ 2120: From 1996 November production.

4. Measure carried out to improve problems of rising temperatures in the DC PWB.
1.Model Name:SF-2020/1020/2120/1 120
2.General:A change has been carried out in the models listed above as a measure to prevent the
temperatures in the DC PWB from rising. The straightening bridge diode has been
change to a shot key type which has a small electrical power consumption (low
temperature).
3.Action:From 1996 October production.
