I have a new worlds cooker that contains an AUTO-PROGRAMMER unit. I need to restart this unit following a power cut. I have done this before, when needed, it is done by a sequence of operations using some of the five control buttons on the AUTO-PROGRAMMER but this is quite a complex operation and I have lost my handbook which tells me the details. I have had the unit for about 30 years, it is still operational but without the handbook I cannot do it. The only ID I can find is the AUTO-PROGRAMMER and the NEW WORLD sign on the cooker.
Can I get details from you on how to proceed please? The programmer contains five control buttons marked with various symbols identified in the handbook and a visual display that is currently operational and is indicating the time.
