1) This kinda sucks for a security device to be flashing it's failure state to all and sundry so its obvious that its not working. It should just turn red or something.
2) I have the little sim slot key - but it doesnt say anywhere in the manual. Do I poke it in the hole on the front of the unit? Or will I destroy a light sensor if I poke it in there!

Just need to pop it off and reset it. I know I ahve to jam it in somewhere - i guess its that little hole but i tried it and didnt want to push too hard....
Thanks
Jon
