Weather Proof (not water proof) do not submerge unit in water)

MAKE SURE WHEN SETTING A TIME TO COME ON THAT'S EARLIER THAN THE EXISITING TIME, THE TIMER WILL COME ON YOUR SET TIME ON THE NEXT SCHEDULED DAY
For instance, if you are setting the clock and it's 11:00 am, and you set the timer to come on at 7 am, it's not going to come on until the next scheduled day, as it is already past 7 am when you are setting the timer.
