Power Saving Function The Power Saving function enters a seep state automaticay whenever the watch is eft in an area where it is dark for a certain period. The tabe beow shows how watch functions are affected by the Power Saving function. Approximate Period in seep state to 7 days 8 days or more Functions LCD off Aarm, houry time signa, anaog timekeeping and auto receive enabed LCD off, aarm and houry time signa disabed Anaog timekeeping stopped at 12 o cock Auto receive disabed The seep state is indicated by a bank screen. Wearing the watch inside the seeve of cothing can cause it to enter the seep state. To recover from the seep state Perform any one of the foowing operations. Move the watch to a we-it area. Press any button. Auto Return Features f you eave the watch in the Aarm Mode or Hand Setting Mode, or with the Battery Leve indicator dispayed for two or three minutes without performing any operation, it returns to the Mode automaticay. f you eave the watch with the Last signa screen dispayed for one or two minutes without performing any operation, it returns to the Mode automaticay. f you eave the watch with a fashing setting on the dispay for two or three minutes without performing any operation, the watch exits the setting screen automaticay. Scroing C is used in various modes and setting screens to scro through data. n most cases, hoding down C during a scro operation scros through the data at high speed. nitia Screens When you enter the Dua Time or Aarm Mode, the data you were viewing when you ast exited the mode appears first. Radio-controed Atomic Precautions Strong eectrostatic charge can resut in the wrong time being set. The time caibration signa is bounced off the ionosphere. Because of this, such factors as changes in the refectivity of the ionosphere, as we as movement of the ionosphere to higher atitudes due to seasona atmospheric changes or the time of day may change the reception range of the signa and make reception temporariy impossibe. Even if the time caibration signa is received propery, certain conditions can cause the time setting to be off by up to one second. The current time setting in accordance with the time caibration signa takes priority over any time settings you make. The watch is designed to update the date and day of the week automaticay for the period January 1, 2000 to December 31, 2099. Setting of the date by a time caibration signa cannot be performed starting from January 1, 2100. This watch can receive signas that differentiate between eap years and non-eap years. Though this watch is designed to receive both time data (hour, minutes, seconds) and date data (year, month, day), certain signa conditions can imit reception to time data ony. Normay, the signa reception date shown by the Last Signa screen is the date data incuded in the received time caibration signa. When ony time data is received, however, the Last Signa screen shows the date as kept in the Mode at the time of signa reception. f you are in an area where proper time caibration signa reception is impossibe, the watch keeps time with the precision noted in Specifications. f you have probems with proper time caibration signa reception or if the time setting is wrong after signa reception, check your current time zone, DST (summer time), and auto receive settings. Resetting the seconds to 00 whie the current count is in the range of 30 to 59 causes the minutes to be increased by 1. n the range of 00 to 29, the seconds are reset to 00 without changing the minutes. The day of the week is dispayed automaticay in accordance with the date (year, month, and day) settings. The year can be set in the range of 2000 to 2099. The watch s buit-in fu automatic caendar makes aowances for different month engths and eap years. Once you set the date, there shoud be no reason to change it except after you have the watch s battery repaced or when battery power drops to Leve 5. The times for the Mode and a the time zones of the Dua Time Mode are cacuated in accordance with each time zones UTC differentia. The UTC differentia is a vaue that indicates the time difference between a reference point in Greenwich, Engand and the time zone. The etters UTC is the abbreviation for Universa Time Coordinated, which is the word-wide scientific standard of timekeeping. t is based upon carefuy maintained atomic (cesium) cocks that keep time accuratey to within microseconds. Leap seconds are added or subtracted as necessary to keep UTC in sync with the Earth s rotation. 12-hour/2-hour Formats The 12-hour/2-hour timekeeping format you seect in the Mode is aso appied in a other modes. With the 12-hour format, the PM indicator (P) appears on the dispay for times in the range of noon to 11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m. With the 2-hour format, times are dispayed in the range of 0:00 to 23:59, without any indicator. umination Precautions umination may be hard to see when viewed under direct sunight. umination turns off automaticay whenever an aarm sounds. Frequent use of iumination runs down the battery.
