Sanyo PLC-XL50 - pin code reset

[Harlquinth]

Hi,

 

Does anyone know if there's an easy way of resetting the pin code on a Sanyo PLC-XL50 projector at all?

 

Recently had some projectors swapped over, and on a PLC-XL50 that was swapped out, a pesky student seems to have set the pin code and enabled vibration detection, and everytime it's knocked or moved, the alarm goes off! Have tried searching the internet on ways of disabling it, but best I've found so far is how to get into the service menu, which doesn't help much as I'm afraid to change things when I don't know what the values mean!

 

Many thanks, Peter.
