Reg:pentax optio m40

[faamariosp]

I am owning a few cameras my self but my favorite is a Pentax Optio M40.
Small stylish and takes reasonably good photos until a few months before.
Its now taking blurry pictures due to dust that got into the lens and i cant
fix it my self. I usually fix my own cameras cause there are no such service
in my country or its to expensive.
The problem is that i did not find any guide to dismantle it yet.
Can someone out there help me?
Thanks in advance.
