Usally 3 pins will be used (Vcc, GND and Output) and the initials will be written on the board. You may try to locate the same or upload a high resolution picture without which it is hard to see with a bulr image.

Hi Vantusaonho,

The only thing I found is what you can see in attachement.

The green wires are piece of metal that hold the batteries, so this piece of metal is fixed throw the holes and is the positive of the batteries.
under theses pieces of metal the circle pad is the minus.
Like these batteries (by example type LR44) are in serie you have VCC=2*1.5v=3v.

I hope this help a little.

Best regards.
