Re: how can I inter to s.p program for sharp ar-m236
Basicly there is not a trick to the S.P. mode. You go in to it & touch The S.P. on the display and then turn the main power switch off and then back on and that is that is needed. But if that did not work you will need to go deeper in to the problem.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
