NSM Digital Thunder Wall mount problem ER 30

[Dessiemc34]

Hi - I have a digital thunder wall mounted jukebox ( circa 1995 )

Serial number is 60003237.

The machine has functioned well for over 12 years until now. Error has came up on the screen - reading PO44 ER 30. I think a chip has gone - until I can get this chip replaced can I reprogram the jukebox to take coins again ? As it won't give me any credits for coins now , and will this memory disappear once the machine is switched off ?

Could you possibly send me the sequence to set the jukebox up for 30p one play 50p for two and four for £1 ?
 
Im in the Uk. I have the manual but it is not very clear. After I pull out the programme button I don't seem to be able to command the machine to remember to allot plays to money entered. It just takes the money and gives no credits.

Thanks.

programming them is very straight forward
once u are in program mode
u enter the start  mode #
what this means is the number where u expext the coin value to be 41 lets say
so u enter h key once digital should go blank
so u enter 40h after that
the left digits are the start of the page 41-47
so with a simple hit of the h key it steps through for u , and displays it
if u are not getting that far? your battery backed up dallas ram is gone (replace it)
