1. The alarm sound is sufficient to wake you up. 2. The display is always on. 3. The device does not have a memory function, so the time must be reset after a power cut. 4. There may be discrepancies when compared to professional thermometers. The weather forecast is for reference only, and the projection head can rotate 180 degrees. 5.
