When the battery is low, a battery icon appears on the screen to notify you that the battery needs to be replaced. There are 2 strong magnets on the back of the timer, which allow it to be firmly attached to any metal surface. Long press the [ST/SP] button to switch the multi-function timer to clock mode.
