Find the AC sign and the arrow that points to a hole, then look for a (-) sign.
Stick one end of the tweezers on the hole where the AC sign points to, then another end of the tweezers on the circle next to the (-) sign, and hold it for 2 seconds.
If the tweezers are not pointy enough to stick into the AC hole, bending a paperclip into an arch will do the job.
