Absolutely the worst instructions ever. Doesn't matter, this thing isn't supposed to be serviced.

1. It's nearly impossible to remove the faceplate without breaking it.

2. Doesn't show which side the ribbon cable is on, important for opening!

3. Doesn't mention the copper item around the battery (strain gage for detecting puffing?) or its wiring. This is stuck onto the battery, and the replacement battery doesn't come with it. It will be destroyed if you try to peel it off the old battery. I have no idea if the unit will function with this bit disconnected/destroyed.
