Once fully charged by exposure to light, your watch will give you years of enjoyment and reliability. Notice All repairs performed on this watch are to be performed at the CITIZEN. When desiring to have your watch repaired or inspected, please contact the Authorized Citizen Service Center either directly or through the store where you purchased your watch. 4 Please use this watch after it has been sufficiently charged by exposure to light. If the second hand of the watch is moving at two-second intervals, this indicates the watch is insufficiently charged. To ensure proper operation, the watch should be fully charged by placing the watch under direct sunlight for about eight (8) hours. We recommend the watch keep a high charge level to ensure optimum operation. Charge your watch as indicated in "Guide to Charging Time" (p. 100). 5 Part Names (1) Charge level indicator/ radio wave reception indicator Home time hour hand UTC hour hand UTC minute hand Home time minute hand Button (B) 24-hour hand Digital display 2 (Displays the home city) Crown Crown for turning the outside scale Button (A) Home time second hand Mode hand Digital display 1 (Displays world city/ world time) � The illustrations shown in this manual may differ from the actual watch you have purchased. 6 Part Names (2): Digital Displays [Digital display 2] Home city name [Digital display 1] World city name Insufficient charge warning mark World city time Hour/minute/second Chronograph measurement mark Timer measurement mark Alarm setting mark Daylight saving time setting mark Morning: A Afternoon: P Note: To assist in the explanation, all parts of the digital display are shown in the illustration. 7 Part Names (3): Radio Wave Reception Display NO: Signal reception failed RX: Reception standby H, M, L: Reception level/ reception status JPN : JJY (Japan) USA : WWVB (USA) EUR : DCF77 (Germany) CHN: BPC (China) 8 Modes where reception is possible: CAL, TME and RX-S 1. Your Watch World Time Eco-Drive Radio Controlled Watch <Radio Signal Reception Function> This watch is a radio controlled watch, which receives the standard time radio waves that are broadcast from radio wave transmitters in four regions, Japan, the USA, Europe (Germany) and China, and uses these waves to automatically correct the time and date. (p. 18) Automatic reception: The watch will automatically receive the radio wave up to three times a day, at 2 a.m., 3 a.m. and 4 a.m., and adjust the time and date accordingly. The 4 a.m. automatic reception can be changed to any time of the day. On demand reception: The radio wave can be received at any time of the day to adjust the time and date. In the event that a radio signal cannot be received, the watch can be manually set and will operate keeping time within +/- 15 seconds per month. 9 <World Time Function> UTC (Coordinated Universal Time), the time and date of 43 cities (or regions) from around the world and one city (any can be set) can be displayed and easily called up. It is convenient when traveling overseas on business or vacation. Daylight saving time can also be set. (p. 46) <Solar Power Function> This is a multi-functional Eco-Drive watch, which is equipped with a solar power function for powering the watch by converting light energy into electric energy. Charge level display function: This function displays the charge level in four grades, to give an approximate indication of how much the rechargeable cell is charged. (p. 40) Power saving function: The watch is equipped with two power saving functions. If the watch face is not exposed to light for 30 minutes or longer, all the LCD display sections turn off (Power saving 1). If the watch face is then not exposed to light for one week or longer, some of the watch's function are stopped in order to minimize the watch's power consumption (Power saving 2). (p. 96) 10 Important Points Regarding Radio Wave Reception There are two methods to receive radio signals during normal operation, Automatic and On Demand. The internal unidirectional antenna may be weakened by geography or building structures, which may require the user to place the watch near a window. When receiving radio waves: * Remove the watch from your wrist * Face the 9:00 position of the watch towards a window * Place the watch on a stable surface * Do not move the watch during this process. Movement of the watch may cause incomplete reception. During radio reception, the second hand of the watch moves in reception level. * When reception is complete, the watch will return to movement at one-second intervals. Reception can take from about 2 minutes to a maximum of 15 minutes. 11 2. Before Use NO: Signal reception failed RX: Reception standby Reception level/ reception status H : High M : Middle L : Low Check the movement of the second hand. The second hand is moving at 1-second intervals. Crown Button (A) Mode hand The second hand is moving at 2-second intervals or is stopped. [Insufficient charging] Charge level indicator [Fully charged] Charge the watch sufficiently by placing it in direct sunlight as indicated in "Guide to Charging Time" (p. 100). 12 Check the reception status. � Pull out the crown to position 1. � Turn the crown to align the mode hand with TME. � Return the crown to the normal position. � Press the lower right button (A) at the 4:00 position. (p. 26) The second hand indicates a reception status of H, M or L The second hand indicates a reception status of NO Your watch is correctly receiving the standard time radio wave. It is ready to use. Refer to "On Demand Reception" (p. 20) to perform the radio wave reception. If you are unable to receive radio waves, please inquire to the Authorized Citizen Service Center. 13 [Checking the Reference Position] Before using the watch, confirm that the hands are aligned with "0", similar to when setting weighing scales The reference position may become misaligned when the watch is exposed to strong magnetism, static electricity or impacts. Even if radio waves are received, the correct time will not be indicated unless the watch hands are aligned to the correct reference position. Check that the hands are properly aligned with "0". Examples of magnetic products that can affect the watch. � Health products (for example, medical necklaces and waist bands that have magnetic fields) � Refrigerators (magnetic part of the door) � Electromagnetic cookers � Bags (with magnet fasteners) � Mobile phones (speaker part) Keep the watch away from items similar to those above. 14 1. Pull the crown out to position 1 and turn to align the mode hand with CHR (chronograph mode). 2. Pull out the crown to position 2. � The hands will move rapidly, stopping at the reference position recorded in the watch memory. Correct reference positions Charge level indicator: CHN UTC hour and minute hands: 12:00 Hour, minute and second hands: 12:00:00 24-hour hand: 12:00 3. If the reference position is correct, the check is now complete. Press the crown back into its normal position. � If a position is incorrect, refer to step 3 and later in "Adjusting the Reference Position" and adjust it to the correct position.

Basic Watch Operations * The watch receives the radio wave from the radio wave transmitter located in the home city's region. Home time hour hand Home time minute hand 1. Check the charge level. 2. Set the home city. If the city in which you are (p. 40) situated is displayed in digital display 2, Button (B) Crown Digital display 1 Button (A) Home city (Digital display 2) 16 Home time second hand (1) Pull out the crown to position 1 and turn to align the mode hand with TME. (2) With the crown pulled out to position 1, press button (A) or (B) to call up the home city in digital display 1. (3) Press button (A) and button (B) at the same time to display the home city in digital display 2. 3. Set the home time. If the home time is correct, (1) Set the time manually (p. 48) (2) Set the time by receiving the radio wave (p. 20) Caution: If the home city is set to a city that is outside the reception area, the radio wave cannot be received. Set the time manually. 4. Set digital display 1. The world time or date can be displayed on digital display 1. Also, the mode can be switched in order to use the alarm, timer or chronograph. (p. 42) 17 4. Radio Signal Reception Three types of radio signal reception are possible: automatic reception, on demand reception and recovery automatic reception. There are three modes where reception is possible: time (TME), calendar (CAL) and receive set (RX-S). The watch cannot receive signals in any other mode. Display the home city in digital display 2 when receiving the radio wave. � Reception is not possible unless the crown is in the normal position. � If the home city is "UTC", reception is not possible. � Reception is not possible during chronograph or timer measurement. � The reception level may change depending on the surrounding environment. While referring to reception level (H, M or L), change the watch location, direction and angle to try to receive the radio wave. � When the watch is receiving the radio wave, as a general rule, all of the hands will stop. To check the time, hold the lower right button (A) for 2 seconds to cancel radio wave reception. The hands will then return to the current time. � Even while the radio wave is being received, the second hand will continue to rotate to align the minute hand with the current time. This shortens the time it takes to set the correct time. 18 Automatic reception � It is not necessary to operate buttons during automatic reception. � The watch will automatically receive the radio wave every day at 2 a.m., 3 a.m. and 4 a.m. � The 4 a.m. reception can be changed to any time of the day. (p. 68 71) � Reception can be set to OFF. (p. 68 71) <Receiving the radio signals> 1. Remove the watch from your wrist and place on a stable surface in a location, such as near a window, from which radio waves can be easily received, pointing the 9:00 side (reception antenna position) in the direction of the radio wave transmitter. 2. The watch will automatically receive the radio wave every day at 2 a.m. An antenna for receiving the radio signals is located inside the watch (on the 9:00 position). 19 On Demand Reception (Manual Reception) � Signals can be received at any time. [Mode hand position when receiving] <Receiving the radio signals> 1. Pull the crown out to position 1 and turn to align the mode hand with the CAL, TME or RX-S position. 2. Return the crown to the normal position. 3. Remove the watch from your wrist and place on a stable surface near a window where the radio signal can be easily received. 4. Point the 9:00 side of the watch in the direction of the radio wave transmitter, and hold down the lower right button (A) for more than 2 seconds. Release when the confirmation tone sounds and the second hand stops at RX. The second hand will then move to H, M or L, and reception will begin. * Do not move the watch during reception. 5. When the radio wave has been properly received, the second hand will automatically move from H, M or L to the time that was received, all the hands will be corrected, and the second hand will return to 1-second interval movement. * Reception can take a maximum of 15 minutes. 20 Recovery Automatic Reception (Automatic Reception) � If the watch stops due to insufficient charging, expose the watch to sunlight to recharge it. When the watch is recharged sufficiently, it will automatically receive the radio wave once. * Regularly charge your radio controlled watch so it does not become insufficiently charged. The radio wave reception can be checked with "Confirming Reception Status". (p. 26) 21 <Storing Your Radio Controlled Watch> If the watch has received insufficient light for charging or has been kept in a dark location for an extended period of time (one week or more), the Power Save Feature of the watch is activated and the hands of the watch stop. Even though the watch will not show movement, the correct time is kept in memory. When the watch is in the Power Save mode, it will continue to keep the correct time internally. In some instances, "Automatic Reception" may not be successful due to a weak signal reception. When resuming use of the watch after the power save mode has been activated for an extended period of time, you can cancel the Power Save function by placing the watch in light sufficient for charging and performing the "On Demand" reception process to correctly set the time and date. (Refer to page 96 for information on the Power Save Function.) 22 5. Poor Reception Areas It may not be possible to receive radio waves under environmental conditions where reception is difficult or in areas susceptible to radio noise, such as those shown in the illustrations below. While referring to the reception level display, try to find a location with better reception. Inside reinforced concrete buildings or underground Near high-tension electrical lines, railway overhead wires or communication facilities Inside vehicles, including cars, trains and aero planes Near TVs, refrigerators, computers, fax machines and other home electronics or appliances Near cellular phones that are in use Extremely hot or cold locations 23 6. Display during Reception [Reception in progress] [Second hand display] [Receiving level] Radio wave reception indicator Second hand moves to RX and stops. The radio wave reception indicator points to the received transmitter. [Digital display] Off The second hand moves from RX to reception level H, M or L and reception starts. Off Repeatedly switches between on and off 24 [Reception completed] When the reception is successful, the second hand will return to 1-second interval movement and the other hands will be automatically corrected. <Time required for reception> Reception can take from about 2 minutes to a maximum of 15 minutes, depending on factors such as the weather or noise. If the radio wave reception fails, the watch may return immediately to the normal display. [Caution] During reception, the second hand may rotate once and show the reception level again. Do not move the watch until the second hand has returned to 1-second interval movement. If the reception fails, RC and NO are displayed. 25 7. Confirming Reception Status � The result of the radio wave reception can be confirmed. � The daylight saving time setting status of the home city can be confirmed. 1. Pull the crown out to position 1 and set the mode to TME, CAL or RX-S. 2. Press the crown back into its normal position and press the lower right button (A) once to confirm the reception status. The second hand will move to H, M, L or NO. � The daylight saving time setting status for the home time is displayed on digital display 2 (flashes alternately between SMT and ON or OFF). � The radio wave reception indicator points to JPN, EUR, USA or CHN. [Digital display 2] 3. Press the lower right button (A) once. � The watch returns to the normal time display (1-second interval movement). � It also returns automatically to normal display if there are no operations for 10 seconds. 26 Reception level Reception level and reception status H Radio wave was received or is being received under very good reception conditions. M Radio wave was received or is being received under good reception conditions. Radio wave was received or is being received L under not very good reception conditions. NO When reception has failed * The time display may shift slightly depending on the reception environment and internal watch processing even if radio waves are properly received. * H, M and L indicate the reception status and are not connected to the performance of the watch. � If NO is indicated, find a location or direction where the reception is better and perform on demand reception again. (p. 20) 27 8. Reception Area Guidelines This watch can receive standard time radio waves broadcast from Japan (two transmitters), the USA, Europe (Germany) and China. The standard time radio wave to be received can be changed by selecting the city in another region. The maps show the approximate reception areas. However, note that the radio wave condition could change due to factors including the weather (such as lightning) and changes in the season or sunrise/sunset time. The reception area on the map is only guideline, and it may be difficult to receive the radio signal even within the areas indicated on the map. 28 Standard time radio signal Transmitter Ohtakadoya-yama Standard Time Transmitter JPN JJY Japan (Fukushima Transmitter) Hagane-yama Standard Time Transmitter (Kyushu Transmitter) Frequency 40 kHz 60 kHz USA WWVB USA Fort Collins Transmitter, Denver, Colorado 60 kHz EUR DCF77 Germany Mainflingen Transmitter, Southeast Frankfurt 77.5 kHz CHN BPC China Shangqiu Transmitter, Henan 68.5 kHz The standard time radio wave used by this radio controlled watch may be interrupted occasionally due to special circumstances at the radio wave transmitter. Even if reception of the standard time radio wave has failed, the watch will continue to be accurate to within �15 seconds per month. 29 JPN: JJY (Japan) Automatically selects one of the two transmitters Fukushima Transmitter: Radius of approximately 1,500 km from the transmitter Kyushu Transmitter: Radius of approximately 2,000 km from the transmitter 30 CHN: BPC (China) Shangqiu, Henan: Radius of approximately 1,500 km from the transmitter 31 USA: WWVB (USA) Fort Collins: Radius of approximately 3,000 km from the transmitter 32 EUR: DCF77 (Germany) Mainflingen: Radius of approximately 1,500 km from the transmitter 33 9.

Elapsed time: This indicates 10 minutes have elapsed since 9:10. 79 <Measuring remaining time> You can tell how much time remains by aligning the mark (or mark) on the slide rule bezel with the target time. Remaining time: This indicates that 20 minutes remain until 9:25. 80 Model 2 A. Navigation Calculator 1. Calculation of time required Problem: How long does it take an airplane flying at 180 knots to fly a distance of 450 nautical miles? Solution: Set the 18 mark on the outside scale to the SPEED INDEX ( ). At this time, the point on the inside scale that is aligned with 45 on the outside scale indicates (2:30), and the answer is 2 hours and 30 minutes. 81 2. Speed (Ground Speed) Calculation Problem: What is the speed (ground speed) of an airplane when it takes 1 hour and 20 minutes to fly a distance of 240 nautical miles? Solution: Align the 24 on the outside scale with 1:20 (80) on the inside scale. At this time, 18 is aligned with the SPEED INDEX ( ) on the inside scale, and the answer is 180 Kt. 82 3. Flying distance calculation Problem: What is the flying distance traveled in 40 minutes at a speed of 210 knots? Solution: Align the 21 on the outside scale with the SPEED INDEX ( ) of the inside scale. The 40 of the inside scale is now pointing to 14, and the answer is 140 nautical miles. 83 4. Fuel consumption rate calculation Problem: If 120 gallons of fuel are consumed in 30 minutes' flying time, what is the fuel consumption rate? Solution: Align the 12 of the outside scale with 30 of the inside scale. The SPEED INDEX ( ) now points to 24, and the answer is 240 gallons per hour. 84 5. Fuel consumption calculation Problem: How much fuel is consumedin 6 hours at a fuel consumption rate of 250 gallons per hour? Solution: Align the 25 of the outside scale with the inside scale's SPEED INDEX ( ) of the inside scale. The 6:00 is aligned with 15, and the answer is 1500 gallons. 85 6. Maximum flying hours Problem: With a fuel consumption rate of 220 gallons per hour and a fuel supply of 550 gallons, what is the maximum number of flying hours? Solution: Align the 22 of the outside scale with the inside scale's SPEED INDEX ( ) of the inside scale. The 55 of the outside scale is now aligned with 2:30, and the answer is 2 hours and 30 minutes. 86 7. Conversion Problem: How do you convert 30 miles into nautical miles and kilometers?

Solar Power Function This watch uses a rechargeable cell to store electrical energy. When the watch is fully charged, it will run for about 6 months. <Ensuring best operation of the watch> Always store the watch in a bright location for best results. An effective way of charging the watch is to keep it in a bright location when you are not wearing it, such as near a window where it can receive direct sunlight. 92 Wearing clothes with long sleeves makes it difficult for the watch to get the necessary light, resulting in insufficient charging. We recommended that you charge the watch for a long time in direct sunlight once a month. [Caution] Do not charge on surfaces that can easily become hot, such as a car dashboard. 93 25. Characteristics of the Eco-Drive Watch When the watch is insufficiently charged, the indication will be changed as follows: [Normal display] [Insufficient charge warning] The watch has been insufficiently charged because the watch face, which contains the solar cell, has not received sufficient light. 2-second interval movement The second hand starts to move in 2-second intervals and the mark flashes in digital display 1. 94 * 1. When the watch stopped due to insufficient charging � It takes at least 30 minutes to recharge sufficiently to perform recovery automatic reception, even if the watch is being exposed to light. After recovery, refer to "Guide to Charging Time" (p. 100) and sufficiently charge the watch. * 2. If the watch failed to perform recovery automatic reception � The time is incorrect even if the second hand moves at 1-second intervals, so after fully charging the watch, set the time manually or perform on demand reception. The insufficient charge warning (a 2-second interval movement) continues for more than 3 days. The watch will stop due to an insufficient charging. [Recovery automatic reception] Sufficiently charge by exposing the watch face, which contains the solar cell to light.*1 When a radio signal has been successfully received*2 When the watch is recharged sufficiently, it will receive the radio signal automatically once. 95 A. Power Saving Function If the watch face is not exposed to light for a long time, the power saving function is activated to minimize the battery consumption. � Power saving 1: When power is not generated for more than 30 consecutive minutes, the digital displays go off to save power. � Power saving 2: When the power saving 1 condition continues for 7 days or longer, to save power, the hour hand, minute hand, second hand and 24-hour hand move to the reference position, and the charge level indicator and UTC hands (hour and minute) stop in their current positions. � The correct time continues to be kept inside the watch. � The alarm tone will not sound. [Normal diaplay] [Power saving 1] [Power saving 2] Digital display areas all go off The digital display areas all go off and the hands stop. Not exposed to light for 30 minutes or more Not exposed to light for 7 days or more 96 <Canceling the power saving function> The power saving function will be automatically canceled when the watch face is exposed to light. � When power saving 1 is canceled, the digital display is restored. � After the power saving 2 has been canceled, the hands will rapidly move to the current time and return to 1-second interval movement. � If the watch is insufficiently charged, the second hand will begin the 2-second interval movement. Return the second hand to 1-second interval movement by sufficiently charging the watch. � Power saving is cancelled if the insufficient charge warning function activates during power saving mode. 97 B. Insufficient Charge Warning Function When the charge level indicator reaches level 0, the second hand's movement changes from 1-second intervals to 2-second intervals and the mark flashes in digital display 1 to show that the watch is insufficiently charged. The watch will stop due to insufficient charging about 3 days after starting the 2-second interval movement if kept in a place with no light. 2-second interval movement [Caution] During 2-second interval movement, the digital displays and watch operations change as follows. � The time cannot be adjusted manually, or by using automatic reception or on demand reception. � Push button operations are not possible. � All modes change to time mode. � The alarm tone and confirmation tone will not sound. (When the timer, chronograph or alarm is used) � The LED lights will not come on. � The chronograph and timer are forcibly reset and cannot be operated. 98 If the charging insufficiency occurs during radio signal reception, the operation will stop automatically, the watch will return to the time before the operation, and 2second interval movement will begin. Regularly charge your radio controlled watch so it does not become insufficiently charged. C. Overcharging Prevention Function When the rechargeable cell becomes fully charged by exposing the watch face to light, the overcharging prevention function is automatically activated to prevent the battery from being charged further. No matter how much the watch is charged, it will not affect the rechargeable cell, timekeeping, functions or performance of the watch. 99 D. Guide to Charging Time Below are the approximate times required for charging when exposing the watch dial to light continuously. This table is for general reference only and does not represent exact charging times. Environment Outdoors (sunny) Charging Time (approximate) Illuminance (lx) To keep working normally for one day To start working normally when the rechargeable cell is empty To charge fully when the rechargeable cell is empty 100,000 4 minutes 40 minutes 30 hours Outdoors (cloudy) 10,000 12 minutes 2 hours 60 hours 20 cm (7-7/8 inches)from a fluorescent lamp (30W) 3,000 40 minutes 5 hours 150 hours Interior lighting 500 4 hours 30 hours -- * If the second hand is moving in 2-second intervals, refer to "To charge fully when the rechargeable cell is empty" and fully charge. 100 To keep working normally for one day ... The charging time to run the watch for one day with normal movement. To charge fully when the rechargeable cell is empty ... The time for full charging after the watch has stopped due to an insufficient charging. [Caution] A fully charged battery will run the watch for about 6 months without further charging. During power saving mode, the correct time continues to be kept inside the watch for approximately three and a half years. Charge the watch every day, as it will take a long time to recharge it, as is indicated in the table, when it stops due to an insufficient charging. Furthermore, it is recommended to charge your watch by exposing to direct sunlight for a long time once a month. 101 E. Handling Your Eco-Drive Watch WARNING Handling the rechargeable cell Do not remove the rechargeable cell from the watch yourself, unless unavoidable. If you must remove the battery, store it out of reach of children to avoid accidental ingestion. If the rechargeable cell is ingested, consult a doctor immediately. Do not throw away with regular trash. Doing so could cause a fire or environmental damage. Follow the collection procedures as specified by your local authority. WARNING Do not use anything other than the specified rechargeable cell The watch will not operate if incorrect battery types are inserted. Never use a regular silver battery. The battery could overcharge during the charging process and burst, causing damage to the watch or injuries to the wearer. 102 CAUTION Charging precautions Do not charge the watch in a high-temperature environment (about 60�C / 140�F or more). Overheating while charging can cause the watch exterior to become discolored, the watch to deform or the movement to be damaged. Example: � Charging close to incandescent lighting, halogen lamps, or other lighting sources that easily become hot. � Charging on surfaces that can easily become hot, such as a car dashboard. When charging with incandescent lighting, halogen lamps, or other lighting sources that easily become hot, place the watch at least 50 cm (20 in.) away from the source to avoid overheating. 103 Troubleshooting <Radio Signal Reception Function> Problem Check � Is the home city (digital display 2) set to the same reception area as your current location? Remedy � Check the map and change the setting. � Check the map. (p. 28 33) � Change the setting. (p. 44 45) Radio signals cannot be received. � Are you moving the watch while receiving a signal and the second hand is showing RX, H, M or L? � Do not move the watch until the signal has been properly received (until normal hand movement is restored). (Reception can take from about 2 minutes to a maximum of 15 minutes.) 104 Problem Radio signals cannot be received. Check � Are there objects nearby that could block radio signals or generate noise? � Are you attempting to receive the radio signal in a location far from a window? � Is the second hand moving at 2second intervals? (When the second hand moves in 2-second intervals, the insufficient charge warning mark flashes in the digital display 1 and the charge level indicator points at level 0.) Remedy � Avoid objects that block radio signals or generate noise. Try to receive radio signals by pointing the 9:00 position of the watch in the direction of the radio signal transmitter. Find a location such as window that is conducive to radio signal reception and change the watch location, direction and angle. (p. 23) � Radio waves cannot be received when the charge is insufficient. Charge the watch sufficiently by placing it in direct sunlight as indicated in "Guide to Charging Time". (p. 100) 105 Problem Radio signals cannot be received. Check Remedy � Is the mode hand pointing to a mode other than TME, CAL or RX-S? � Is chronograph or timer measurement in progress? � Pull the crown out to position 1 and set the mode to TME, CAL or RX-S. � Stop the measurement, reset, and try to receive the radio wave again. The time is not correct. � Is the reference position set correctly? Check the reference position. (p. 14) � If the reference position is not correctly set, adjust it as indicated in "Adjusting the Reference Position". (p. 74) 106 Problem The time is not correct. Check Remedy � Check the reception status. � Check whether the daylight saving time is ON or OF (off). (p. 46) � If the reception status is NO, change your location and try to receive the radio wave again. "On Demand Reception" (p. 20) � In TME or WT-S mode, select daylight saving time ON or OF (off). The watch successfully received the radio wave, but it deviates slightly from the correct time. The second hand moved suddenly to the reception standby (RX) position. � Have you set the 4 a.m. automatic reception to a different time? � A slight deviance (less than 1 second) may be caused by the internal processing of the watch. � Check again the automatic reception setting of the RX-S (receive set) mode. (p. 68) 107 <Eco-Drive> Problem The watch has stopped. Check � Is the charge level indicator pointing at level 0? � Is "ERR" displayed in digital display 1? Remedy � Charge the watch sufficiently until the charge level indicator reaches level 3, as indicated in "Guide to Charging Time". (p. 41) � Reset the watch (p. 72) and then correct the reference position. (p. 74) If "ERR" is displayed again, contact the store where you purchased the watch or a Authorized Citizen Service Center. The watch does not work even after charging. � Did you charge the watch sufficiently in sunlight? � Charge the watch sufficiently, as indicated in "Guide to Charging Time". (p. 100) If the watch does not work even after charging, contact a Authorized Citizen Service Center. 108 Problem The second hand is moving in 2-second intervals. Check � Is the charge level indicator pointing at level 0? Remedy � Charge the watch sufficiently until the charge level indicator reaches the fully charged level. (p. 41) The hands moved forward quickly at the moment that the watch was removed from a desk or drawer. � This is because the power saving mode was canceled when the watch was exposed to light, and the hands moved forward quickly to the current time. It is ready to use. (p. 96) The hands or digital displays are abnormal. � Reset the watch. (p. 72) (The internal watch system became unstable because of strong static electricity or other external influence.) 109 Precautions WARNING: Water-resistance performance There are several types of water-resistant watches, as shown in the following table. The unit "bar" is roughly equal to 1 atmosphere. * WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar. Indication Dial Case (case back) WATER RESIST or no indication WATER RESIST(ANT) WR 50 or WATER RESIST 50 WR 100/200 or WATER RESIST 100/200 WATER RESIST(ANT) 5 bar or WATER RESIST(ANT) WATER RESIST(ANT) 10bar/20 bar or WATER RESIST(ANT) 110 Specifications Minor exposure to water (washing face, rain, etc.) Water-resistant to 3 atmospheres OK Water-resistant to 5 atmospheres OK Water-resistant to 10/20 atmospheres OK For correct use within the design limits of the watch, confirm the level of waterresistance of your watch, as indicated on the dial and case, and consult the table. Examples of use Moderate exposure to water (washing, kitchen work, swimming, etc.) NO OK OK Marine sports (skin diving) NO NO OK Scuba diving (with air tank) NO NO NO Operation of the crown or button with moisture visible NO NO NO 111 WARNING: Water-resistance performance � Water-resistance for daily use (to 3 atmospheres): This type of watch is water-resistant to minor exposure to water. For example, you may wear the watch while washing your face; however, it is not designed for use underwater. � Upgraded water-resistance for daily use (to 5 atmospheres): This type of watch is waterresistant to moderate exposure to water. You may wear the watch while swimming; however, it is not designed for use while skin diving. � Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of watch may be used for skin diving; however, it is not designed for scuba or saturated diving using helium gas. CAUTION � Be sure to use the watch with the crown pressed in (normal position). If your watch has a screw-lock type crown, be sure to tighten the crown completely. � Do NOT operate the crown or button with wet fingers or when the watch is wet. Water may enter the watch and compromise water-resistance. � If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth. � If moisture has entered the watch, or if the inside of the crystal is fogged up and does not become clear within a day, immediately take the watch to your dealer or Authorized Citizen Service Center for repair. Leaving the watch in such a state will allow corrosion to form inside. 112 � If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off. CAUTION: Keep your watch clean. � Leaving dust and dirt deposited between the case and crown may result in difficulty in pulling the crown out. Rotate the crown while in its normal position, from time to time, to loosen dust and dirt and then brush it off. � Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally. Cleaning the Watch � Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal . � Use a soft, dry cloth to wipe off perspiration and dirt from the leather band. � To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer. NOTE: Avoid using solvents (thinner, benzine, etc.), as they may damage the finish. 113 CAUTION: Operating environment � Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where temperatures are outside the specified range, may result in deterioration of functions or even stoppage of the watch. � Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn. � Do NOT leave the watch in a place where it is exposed to high temperature, such as the glove compartment or dash-board of a car. Doing so may result in deterioration of the watch, such as deformation of plastic parts. � Do NOT place the watch close to a magnet. Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a mobile phone. If this has occurred, move the watch away from the magnet and reset the time. � Do NOT place the watch close to household appliances that generate static electricity. Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen. � Do NOT subject the watch to a strong shock such as dropping it onto a hard floor. 114 � Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases. If solvents, such as thinner and benzine, or substances containing such solvents come in contact with the watch, discoloration, melting, cracking, etc. may result. If the watch comes in contact with mercury used in thermometers, the case, band or other parts may become discolored. Periodical inspections Your watch needs inspection once in every two or three years for safety and long use. To keep your watch water-resistant, the packing needs to be replaced regularly.
