Hand Setting Mode watch Mode Time Recorder Mode Radio-controed tomic Timekeeping Hour hand Minutes hand This watch receives a time caibration signa and updates its time setting accordingy. The time caibration signa incudes both Standard Time and ayight Saving Time (summer time) data. This watch is designed to pick up the time caibration signa transmitted from Fort Coins, Coorado (US). Reception is possibe within North merica*. * The term North merica in this User s Guide refers to the area that consists of Canada, the continenta United States, and Mexico. Current Time Setting This watch automaticay adjusts its digita time setting in accordance with a time caibration signa. You can aso perform a manua procedure to set the time and date, when necessary. The first thing you shoud do after purchasing this watch is to set your Home City, which is the city where you wi normay use the watch. For more information, see To set your Home City beow. When using the watch outside of the range of the transmitter in Fort Coins, you need to manuay adjust the time as required. See Timekeeping for information about manua settings. The anaog time of this watch is synchronized with the digita time. Because of this, the anaog time setting is automaticay adjusted whenever you change the digita setting.

Normay, your watch shoud show the correct time as soon as you seect your Home City code. If it does not, it shoud adjust automaticay after the next auto receive operation (in the midde of the night). You can aso perform manua receive or you can set the time manuay. If you are in an area that does not use ayight Saving Time (summer time), turn off the ST setting. Time Caibration Signa Reception There are two different methods you can use to receive the time caibration signa: auto receive and manua receive. uto Receive With auto receive, the watch automaticay picks up the time caibration signa four times a day at 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m. For more information, see bout uto Receive. Manua Receive Manua receive ets you start a time caibration receive operation with the press of a button. For more information, see To perform manua receive. Important! Position the watch as shown in the nearby iustration, with its 12 o cock side facing towards a window. Make sure there are no meta objects nearby. Resin Band Meta Band The watch shoud not be on its side or facing the wrong way. Proper signa reception can be difficut or even impossibe under the conditions isted beow. Inside or among buidings Inside a vehice Near househod appiances or office equipment, or a mobie phone Near a construction site, airport, or other sources of eectrica noise Near hightension power ines mong or behind mountains Signa reception is normay better at night than during the day. Time caibration signa reception takes from two to six minutes, but in some cases it can take as ong as 12 minutes. Take care that you do not perform any button operations or move the watch during this time. 600 mies 2,000 mies Fort Coins t distances further than about 600 mies (1,000 kiometers) from the transmitter, signa reception may not be possibe during certain times of year or times of day. Radio interference may aso cause probems with Even when the watch is within the reception range of the transmitter, signa reception is impossibe if the signa is bocked by mountains or other geoogica formations between the watch and signa source. Signa reception is affected by weather, atmospheric conditions, and seasona changes. See the information under Signa Receive Troubeshooting if you experience probems with time caibration signa bout uto Receive When auto receive is turned on, the watch automaticay starts to receive the time caibration signa when the digita time in the Timekeeping Mode reaches 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m. each day (caibration times). 1

2 Operation Guide COMBIWVE1 The auto receive operation is performed ony if the watch is in the Timekeeping Mode or Word Time Mode when one of the caibration times is reached. It is not performed if a caibration time is reached whie an aarm is sounding, or whie you are configuring settings (whie settings are fashing on the dispay). uto receipt of the caibration signa is designed to be performed eary in the morning, whie you seep (provided that the Timekeeping Mode time is set correcty). Before going to bed for the night, remove the watch from your wrist, and put it in a ocation where it can easiy receive the signa. When auto receive is turned on, the watch receives the caibration signa for two to six minutes everyday when the digita time in the Timekeeping Mode reaches each of the caibration times. o not perform any button operation within six minutes before or after any one of the caibration times. oing so can interfere with correct caibration. Remember that reception of the caibration signa depends on the time kept in the digita dispay. The receive operation wi be performed whenever the dispay shows any one of the caibration times, regardess of whether or not the dispayed time is actuay the correct time. When two, three, or four receptions are successfu, the watch uses the data of the ast reception for caibration. When ony one reception is successfu, the watch uses the data of the successfu bout the Receiving Indicator The receiving indicator shows the strength of the caibration signa being received. For best reception, be sure to keep the watch in a ocation where signa strength is strongest. Receiving indicator Weak Strong (Leve 1) (Leve 4) Even in an area where signa strength is strong, it takes about 10 seconds for signa reception to stabiize enough for the receiving indicator to indicate signa strength. Use the receiving indicator as a guide for checking signa strength and for finding the best ocation for the watch during signa receive operations. Foowing reception of the time caibration signa and caibration of the watch s time setting, the Leve 4 receiving indicator wi remain on the dispay in a modes. The Leve 4 receiving indicator wi not be dispayed if signa reception was unsuccessfu or after you adjust the current time setting manuay. The Leve 4 receiving indicator is dispayed ony when the watch is abe to successfuy receive both time and date data. It does not appear when ony time data is received. The Leve 4 receiving indicator indicates that at east one of the auto caibration signa receive operations was successfu., however, that the Leve 4 receiving indicator is ceared from the dispay at 3:00 a.m. each day.

Initia Screens When you enter the Word Time, arm, or ate ert Mode, the data you were viewing when you ast exited the mode appears first. Radio-controed tomic Timekeeping 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. 4

5 Operation Guide COMBIWVE1 The current time setting in accordance with the time caibration signa takes priority over any time settings you make. The watch is designed to automaticay update the date and day of the week for the period January 1, 2000 to ecember 31, Setting of the date by the time caibration signa cannot be performed starting from January 1, 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 date as kept in the Timekeeping Mode at the time of signa If you are in an area where proper time caibration signa reception is impossibe, the watch keeps time within ±20 seconds a month at norma temperature. If you have probems with proper time caibration signa reception or if the time setting is wrong after signa reception, check your current city code, ST (summer time), and auto receive settings. The foowing are the initia factory defauts for these settings. Setting City code ST (summer time) uto receive Initia Factory efaut NYC (New York) (uto switching) ST ON (uto receive) R/C Timekeeping 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. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes. The day of the week is automaticay dispayed in accordance with the date (year, month, and day) settings. The year can be set in the range of 2000 to 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. The current time for a city codes in the Timekeeping Mode and Word Time Mode is cacuated in accordance with the Greenwich Mean Time (GMT) differentia for each city, based on your Home City time setting. GMT differentia is cacuated by this watch based on UTC* data. * The etters UTC stands for Universa Time Coordinated, which is the word-wide scientific standard of timekeeping. It 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. The reference point for UTC is Greenwich, Engand. 12-hour/24-hour Timekeeping Formats The 12-hour/24-hour timekeeping format you seect in the Timekeeping Mode is aso appied in a other modes. With the 12-hour format, the P (PM) indicator 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 24-hour format, times are dispayed in the range of 0:00 to 23:59. The indicator 24 indicates the 24-hour format. Iumination Precautions The watch has an EL (eectro-uminescent) pane that causes the entire dispay to gow for easy reading in the dark. In any mode, press B to iuminate the dispay for about one second. The eectro-uminescent pane that provides iumination oses power after very ong use. Iumination may be hard to see when viewed under direct sunight. The watch may emit an audibe sound whenever the dispay is iuminated.
