Never mix electronic components with moisture, though the consequences may not be as dramatic as a spark-induced short circuit. However, it can lead to issues with critical components, such as the corrosion of copper circuits, and water vapor can interfere with and disrupt the pathways of electrical signals, thereby affecting the device's operation. Maybe at times when you set an alarm, the buttons don't respond as expected. After you set it, the LED might display an intriguing scale or even create ghostly digits. Of course, there could be other problems, but if you're aware of the desiccant's purpose, you'll recognize the root cause of the issue and can resolve it immediately! In some cases, a clear example would be a portable camera that won't work without any other explanation; a desiccant might help you fix it as good as new!
