aristocrat 540 MK4 errors and need manual ----Fixed it----

[proten]

I got a 540 MK4 of Craig's list , when I got it it had a code 34 coin comparator error.
After going over and resetting the machine ,I am in a code 12 Metering error.
I'm looking for a manual for this game - Australian made in 1998

Can any one give me any help?  
I can get into the meter set up pages and change all the settings that needed it.
But now I can't set the settings and get back to the game.
  What am I doing wrong!!!!!!!!!!!!!!

To reset. Open the main door. Turn the jackpot key.

Press ROBO/HOP RESET, AUX and MEMTEST simulatenously.

You should now be able to get back into the game after turning the audit key.

I figured it out!!! The person I got it from had did the change over from Australian
to American 5c coins. But in the when they stoped they had put the ribion cable
in the wrong plug.
Thanks to Palindrome for sending me a copy of the manual that he had.
The manual gave me the info I need to track down the problem.
I want to thank all that helped.
