••When power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

••The above times are for reference only. Actual times depend on lighting conditions.
••For details about the operating time and daily operating conditions, see the “Power Supply” section of the Specifications.
Power Saving
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.
••There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark | Operation | |
60 to 70 minutes (second hand sleep) | x Second Hand only stopped at 12 o’clock, all other functions enabled | |
6 or 7 days (function sleep) | ••All functions, including analog timekeeping, disabled | |
••Internal timekeeping maintained | ||
| ||
|
|
••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.
To recover from the sleep state
Move the watch to a

location where it is exposed to light. For details, see Go to step 2. “Charging the Watch”.
2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To configure Home City settings” to configure your Home City and daylight saving time settings.
Important!
Proper time calibration signal reception and World Time settings depend on correct Home City, Home Time, and Home Date settings. Make sure you configure these settings correctly.
3. Set the current time.
••To set the time using a time calibration signal See “To get ready for a receive operation”.
••To set the time manually
See “Configuring Current Time and Date Settings Manually”.
The watch is now ready for use.
••For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic Timekeeping”.
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a
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 “Configuring Current Time and Date Settings Manually” 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.
If your Home City Code setting is this: | The watch can receive the signal from | |
the transmitter located here: | ||

LONDON (LON), PARIS (PAR), ATHENS (ATH) | Anthorn (England), Mainflingen (Germany) | |
HONG KONG (HKG) | Shangqiu City (China) | |

TOKYO (TYO) | Fukushima (Japan), Fukuoka/Saga (Japan) |
HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX), Fort Collins, Colorado (United States) DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC)
Important!
••The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
••When HONOLULU (HNL) or HONG KONG (HKG) 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 configure Home City settings” for information about how to do this.

Charging Guide
Whenever you are not wearing the watch, leave it in a location where it is exposed to light.
••Best charging performance is achieved by exposing the watch to light that is as strong as possible.
Warning!
When wearing the watch, make sure that its face is not blocked from light by the sleeve of your clothing.
••The watch may enter a sleep state if its face is blocked by your sleeve even only partially.

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.
••On the dashboard of a car parked in direct sunlight
••Too close to an incandescent lamp
••Under direct sunlight
Important!
••Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.
••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. Make sure that the watch is exposed to bright light whenever possible.

••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 influence of the above conditions becomes even greater.

••As of January 2010, 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.
••Using this watch in a country covered by a time calibration signal that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.
