Signa reception normay is better at night than during the day. Time caibration signa reception takes from two to six minutes. Take care that you do not perform any button operations or move the watch during this time. Reception Range 600 mies 2,000 mies To dispay the Last Signa screen In the Mode, press to dispay the Last Signa screen (indicated by GET). The Last Signa screen shows the date and time of the ast successfu time caibration signa reception. If you do not press to return from the ast signa screen to the timekeeping screen, the watch wi return automaticay after about two or three minutes. PM ay of week Receive time Fort Coins At 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 interferance may aso cause probems with reception. 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 reception. About Auto Receive When auto receive is turned on, the watch starts to receive the time caibration signa automaticay when the time in the Mode reaches midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (caibration times). The watch wi aso perform an additiona auto receive at 5:00 a.m. if none of the reguary schedued auto receives are successfu. The auto receive operation is performed ony if the watch is in the 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). Auto receive of the caibration signa is designed to be performed eary in the morning, whie you seep (provided that the 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 receive the signa easiy. When auto receive is turned on, the watch receives the caibration signa for two to six minutes everyday when the Mode time reaches each of the caibration times. Avoid performing 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 Mode. The receive operation wi be performed whenever the dispay shows any one of the caibration times, regardess of whether or not the Mode time actuay is 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 reception. About the Receiving Indicator The receiving 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. Weak Strong (Leve 1) (Leve 4) Receiving Use the receiving as a guide for checking signa strength and for finding the best ocation for the watch during signa receive operations. Even in an area where signa strength is strong, it takes about 10 seconds for signa reception to stabiize enough for the receiving to indicate signa strength. Foowing reception of the time caibration signa and caibration of the watch s time setting, the Leve 4 receiving wi remain on the dispay in a modes. The Leve 4 receiving wi not be dispayed if signa reception was unsuccessfu or after you adjust the current time setting manuay. The Leve 4 receiving is dispayed ony when the watch is abe to receive both time and date data successfuy. It does not appear when ony time data is received. The Leve 4 receiving indicates that at east one of the auto caibration signa receive operations was successfu., however, that the Leve 4 receiving is ceared from the dispay at 3:00 a.m. each day.

Initia Screens When you enter the Aarm or Word Time 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 ecember 31, 2099. Setting of the date by the 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. If you are in an area where proper time caibration signa reception is impossibe, the watch keeps time within ±15 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) Auto receive Initia Factory efaut (New York) (Auto switching) (Auto receive) 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.

The current time for a city codes in the Mode and Word Time Mode is cacuated in accordance with the Greenwich Mean Time (GMT) differentia for each city, based on the 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 accurate 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 Formats The 12-hour/24-hour timekeeping format you seect in the Mode is aso appied in a other modes.

Iumination may be hard to see when viewed under direct sunight. The watch may emit an audibe sound whenever the dispay is iuminated. This is due to vibration of the EL pane used for iumination, and does not indicate mafunction. Iumination turns off automaticay whenever an aarm sounds. Frequent use of iumination runs down the battery. Auto ight switch precautions The auto ight switch is turned off automaticay whenever battery power is at Leve 3. Wearing the watch on the inside of your wrist as we as movement or vibration of your arm can cause the auto ight switch to activate and iuminate the dispay. To avoid running down the battery, turn off the auto ight switch whenever engaging in activities that might cause frequent iumination of the dispay. that wearing the watch under your seeve whie the auto ight switch is turned on can cause frequent iumination of the dispay and can run down the battery. More than 15 degrees too high Iumination may not turn on if the face of the watch is more than 15 degrees above or beow parae. Make sure that the back of your hand is parae to the ground. Iumination turns off in about one second, even if you keep the watch pointed towards your face. Static eectricity or magnetic force can interfere with proper operation of the auto ight switch. If iumination does not turn on, try moving the watch back to the starting position (parae with the ground) and then tit it back towards you again. If this does not work, drop your arm a the way down so it hangs at your side, and then bring it back up again. Under certain conditions, iumination may not turn on unti about one second after you turn the face of the watch towards you. This does not necessariy indicate mafunction of the auto ight switch. You may notice a very faint cicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanica operation of the auto ight switch, and does not indicate a probem with the watch.
