film magazine battery

<p>Just bought GX680 I and after removing magazin counter resets to 0 EXP.<br /> I think it's internal battery problem - how to dissasembly magazin?</p>

<p>There are two small cross-head screws on the rear face of the back, above and below the grey latch. You need to undo these. Also, on the top of the back there is a knurled dial that you use to change ISO. The centre of this dial is a screw which also needs to be undone. You need to improvise a tool (maybe the eraser on the end of a pencil), or use an engineer's suction wrench for this (or, if it's been undone in the past, you might be able to turn it with the tip of your thumb).</p>
