HOUSE USE PRODUCTS LCD Display Radio-Controlled Clock - Used This is a radio-controlled clock that is powered by a power outlet. It has a temperature and humidity sensor. The display is bright (with a dimmer function), making it easy to see at night. Operation has been confirmed. The radio wave forced reception didn't work well unless placed near a window in my home. There may be differences between urban and rural areas. The exterior has quite a few fine scratches on the surface of the screen. Size: 158 x 114 x 28mm Cord length: Approximately 3m
