How to program an M+

[jbshocks]

According to the M manual an M type machine has a attract mode that can have a programmable message on the display that it talks about how to program.  The trouble is it mentions using 2 buttons and rotating the jackpot reset both clockwise and counter clockwise.  I only have a M manual not an M+ (my machine is M+) but I would assume the same attract feature would be available.  The M+ does not have 2 buttons so at a minimum that part of the procedure would be different.  Also my jack pot switch is broken but it only has 2 wires so I would assume there is only one direction and no clockwise or counter clock wise.  I would think you either close or open the circuit.  Can anyone confirm if you can put a custom message in the M+ and if so how?  Does anyone have the correct M+ manual?
