How to Set the Time and Date (Radio Signal Reception) NOTICE ・The watch may display the wrong time if it fails to receive radio signals properly because of interference. The watch may also fail to receive radio signals properly depending on the location or radio wave receiving conditions. In this case, move the watch to another place where it can receive radio signals. ・When the watch is out of reception range, its accurate quartz movement will continue to keep the time. ・The time signal transmission may be stopped during maintenance of the facilities of each transmitting station or because of a lightning strike. In such a case, see each station's website for further information or contact SEIKO CUSTOMER SERVICE CENTER. ・Websites of transmitting stations（as of November, 2007） Japan: NICT（Japan Standard Time Group）http://www.jjy.nict.go.jp/ China: NTSC http://www.ntsc.ac.cn T he United States of America: NIST http://www.boulder.nist.gov/timefreq/ stations/wwvb.htm ・SEIKO CUSTOMER SERVICE CENTER: 0120-612-911（toll free in Japan） 101
