It's a motto to live by: change your clocks, change your batteries. We start Standard Time Sunday morning and Canandaigua Fire Department Education Officer Sam Loiacono says after you set your clock back, stick some fresh batteries in your smoke and CO detectors.
Loiacono says you can go one step further and clean out the units.
No home should be without a unit.
So remember: Turn your clocks back Sunday morning, if they don't automatically, and change the batteries in your smoke and carbon monoxide detectors. While you're at it, go ahead and test those detectors too.
