Radio wave reception function: automatic reception (up to 6 times/day) (up to 5 times/day for Chinese radio waves)/manual reception, Receiving radio waves: JJY, frequency: 40kHz/60kHz (models compatible with Fukushima Station and Kyushu Station) Receiving radio waves: WWVB, frequency: 60kHz Receiving radio waves: MSF/DCF77, frequency: 60kHz/77.5kHz Receiving radio waves: BPC, frequency: 68.5kHz * If you set your home time to a city where you can receive radio stations, you will receive the station appropriate for your city. Please note that the time difference varies depending on the selected city. Sensor function details * The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude. If the atmospheric pressure changes due to weather conditions, the altitude of the measured value will also change. * When measuring the outside temperature, take the watch off your wrist to avoid being affected by body temperature, sweat (water droplets), direct sunlight, etc.
