• Run SIM 81 to re-set the display language from Japanese to the desired
language.
• Run SIM 66 again, re-entering the value recorded above
• Re-enter all factory default values as found on the large label on the inside
of the left cover or on the rear panel.

Several new SIMulations are used to control the A741 Repro System, the 2
most important are discussed below:
SIM 115

the server PC will not detect the A741. Default setting after changing the
EPROM’s is off.
SIM 117
