E-19 x For details about the operating time and daily operating conditions, see the “Power Supply” (page E-94) section of the Specifi cations. Power Saving When turned on, Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving. x For information about enabling and disabling power saving, see “To turn Power Saving on and off” (page E-83). x There actually are two sleep state levels: “display sleep” and “function sleep”. Elapsed Time in Dark Digital Dials Operation 60 to 70 minutes (display sleep) Blank Digital dials are off, but all functions are enabled. 6 or 7 days (function sleep) Blank Hour and minute hands stop at 12 o’clock. All functions are disabled, but timekeeping is maintained. E-18 Charging Times Exposure Level (Brightness) Daily Operation *1 Level Change *2 Level 5 Level 4 Level 3 Level 2 Level 1 Outdoor sunlight (50,000 lux) 8 min. 3 hours 23 hours 6 hours Window sunlight (10,000 lux) 30 min. 7 hours 85 hours 23 hours Window sunlight on cloudy day (5,000 lux) 48 min. 11 hours 138 hours 37 hours Indoor fl uorescent lighting (500 lux) 8 hours 138 hours – – – – – – * 1 Approximate exposure each day to generate power for normal daily operation. * 2 Approximate exposure time (in hours) required to take power up one level. x The above exposure times all are for reference only. Actual exposure times depend on lighting conditions. E-17 Power Recovery Mode x Performing multiple illumination, beeper, and/or high-speed hand movement operation during a short period may cause all of the battery power indicators (H, M, and L) to start fl ashing in the lower digital dial. This indicates that the watch is in the power recovery mode. Illumination, alarm, countdown timer alarm, and hourly time signal operations will be disabled until battery power recovers. x Battery power will recover in about 15 minutes. At this time, the battery power indicators (H, M, L) will stop fl ashing. This indicates that the functions listed above are enabled again. x If all of the battery power indicators (H, M, L) are fl ashing and the CHG (charge) message also is fl ashing, it means the battery level is very low. Expose the watch to bright light as soon as possible. x Frequent fl ashing of all of the battery power indicators (H, M, L) probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge. E-16 x At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery reaches Level 2 (M) after falling to Level 5, reconfi gure the current time, date, and other settings. x Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (M). x Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to show a reading temporarily that is higher than the actual battery level. The correct battery level should be indicated after a few minutes. x The current time and all other settings return to their initial factory defaults whenever battery power drops to Level 5 and when you have the battery replaced. E-15 Level Battery Power Indicator Function Status 1 (H) All functions enabled. 2 (M) All functions enabled. 3 (L and LOW) Auto and manual receive, illumination, and beeper disabled. Except for Timekeeping Mode, all other modes disabled. 4 (CHG) All functions and display indicators disabled except for timekeeping and display of CHG (charge) in the lower digital dial. Hour and minute hands stopped at 12 o’clock. 5 All functions disabled. x The fl ashing LOW message at Level 3 (L) tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible. E-14 x Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause power to run down. Expose the watch to bright light whenever possible. Power Levels You can get an idea of the watch’s power level by observing the battery power indicator in the lower digital dial. Battery power indicator E-13 Warning! Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods. x On the dashboard of a car parked in direct sunlight x Too close to an incandescent lamp x Under direct sunlight Important! x Allowing the watch to become very hot can cause the digital displays to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature. x Turn on the watch’s Power Saving function (page E-19) and keep it in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down. E-12 Charging the Watch The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light. Charging Guide Whenever you are not wearing the watch, leave it in a location where it is exposed to light. x Best charging performance is achieved by exposing the watch to the strongest light available. When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing. x The watch may enter a sleep state (page E-19) if its face is blocked by your sleeve even only partially.

To perform manual receive In the Timekeeping Mode, hold down D until the watch beeps. x A signal level indicator (L1, L2, or L3, see page E-32) appears in the lower digital dial after reception starts. Do not move the watch or perform any button operation until GET or ERR appears in the right digital dial. RCVD indicator Receiving E-28 3. What you should do next depends on whether you are using Auto Receive or Manual Receive. x Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” below for details. x Manual Receive: Perform the operation under “To perform manual receive” on page E-29. Auto Receive x With Auto Receive, the watch performs the receive operation each day automatically up to six times (up to fi ve times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed. x When a calibration time is reached, the watch will perform the receive operation only if it is in the Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is reached while you are confi guring settings, while a countdown timer operation is in progress, or while the hands have been moved for easier viewing of the digital dials (page E-79). E-27 x Signal reception may be diffi cult or even impossible under the conditions described below. Inside or among buildings Inside a vehicle Near household appliances, offi ce equipment, or a mobile phone Near a construction site, airport, or other sources of electrical noise Near high-tension power lines Among or behind mountains E-26 To get ready for a receive operation 1. Confi rm that the watch is in the Timekeeping Mode. If it isn’t, use C to enter the Timekeeping Mode (page E-38). 2. The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby. 12 o’clock or x Signal reception normally is better at night. x The receive operation takes from three to eight minutes, but in some cases it can take as long as 16 minutes. Take care that you do not perform any button operation or move the watch during this time. E-25 x Even when the watch is within range of a transmitter, signal reception may be impossible due to the effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the infl uence of the conditions listed above becomes even greater. x Signal reception may not be possible at the distances noted below during certain times of the year or day. Radio interference may also cause problems with reception. − Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles) − Fort Collins (United States) transmitter: 600 miles (1,000 kilometers) − Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles) − Shangqiu (China) transmitter: 500 kilometers (310 miles) x As of December 2014, China does not use Daylight Saving Time (DST). If China does go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly. E-24 Japanese Signals Chinese Signal Fukushima 500 kilometers 1,000 kilometers Fukuoka/Saga Signals are receivable in the Taiwan area when reception conditions are good. 1,500 kilometers Changchun 500 kilometers Beijing Shangqiu Shanghai Chengdu Hong Kong E-23 Approximate Reception Ranges UK and German Signals North American Signal Anthorn 500 kilometers 1,500 kilometers Mainfl ingen The Anthorn signal is receivable within this area. 2,000 miles (3,000 kilometers) 600 miles (1,000 kilometers) Fort Collins E-22 If your Home City Code setting is this: The watch can receive the signal from the transmitter located here: LIS, LON, MAD, PAR, ROM, BER, STO, ATH, MOW Anthorn (England), Mainfl ingen (Germany) HKG, BJS Shangqiu City (China) TPE, SEL, TYO Fukushima (Japan), Fukuoka/Saga (Japan) HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI, NYC, YHZ, YYT Fort Collins, Colorado (United States) Important! x The areas covered by MOW, HNL and ANC are quite far from the calibration signal transmitters, so certain conditions may cause reception problems. x When HKG or BJS is selected as the Home City, only the time and date are adjusted according to the time calibration signal. You need to switch manually between standard time and daylight saving time (DST) if required. See “To confi gure Home City settings” (page E-42) for information about how to do this. E-21 Radio Controlled Atomic Timekeeping This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Confi guring Current Time and Date Settings Manually” (page E-48) for more information. This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception. E-20 x The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state. x The watch will not enter a sleep state while it is in the Stopwatch Mode or Countdown Timer Mode. To recover from the sleep state Move the watch to a well-lit area or press any button.
