Battery change for icn 330
Hi
Carefully remove the front facia, this is a piece of trip that surrounds the buttons on the front, and is best removed by slipping a knife alond the left and right sides of the unit. It does come off easily.
Then you will reveal 4 screws, they hold the front of the unti to the back of the unit. Remove these screws, take care, they are small, and when you replace them do not over tighten them. They are not phillips type screws, they are the hex type, the same type that are used on many mobile phones. You can buy a screwdriver to suit very cheaply.
When all the srews are removed, you can use a knife or flat screwdriver to gently depress the locating lug at the base of the unit in the centre, there are 2 similar lugs at the top, but once the bottom one is dis-located, the two on top can just be lifted over.
When you seperate the two halves,(front & back), take care, as there are 3 wires conected by micro plugs, these can easily be withdrawn, and cannot be confussed as they are all different.
You now have 2 halves, and you will see the speaker and a wire leading behind a locking plate to the battery, remove the 2 screws that are on the locking plate/speaker, and then gently lift the plate off. You now have direct access to the battery and can simply lift it out.
This really sounds complicated when writing it, but seriously, I have just done mine, and until 20 mins ago I had never done it either. It will take you 15 mins max, because you have some instructions to follow. !!
Good luck,
If you overtighten the screw on re-assembly, they will strip the threads and also if the unit is too tight it will affect the operation of the buttons on the front, they wont be able to be depressed or released.
