Operation Guide 5063 (OC)
Important!
ξKeep 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.
ξStoring 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.
ξWhen 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.

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.
ξThere 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) | ξ All functions, including analog timekeeping, disabled | |
ξ Internal timekeeping maintained | ||
|
ξThe 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
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
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 | |

Important!
ξ The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
ξ 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” (page

ξEven 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.
ξSignal 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.
−Mainflingen (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)
ξAs 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.
ξUsing 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.

To get ready for a receive operation
1.Check to make sure the watch is in the regular timekeeping mode. If it isn’t, hold down Cat least two seconds to enter the regular timekeeping mode.
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
ξSignal reception normally is better at night.
ξThe receive operation takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operation or move the watch during this time.
ξSignal reception may be difficult or even impossible under the conditions described below.
Inside or among Inside a vehicle | Near household | Near a | Near | Among or behind |
buildings | appliances, | construction | mountains | |
| office equipment, | site, airport, or | power lines |
|

3.What you should do next depends on whether you are using Auto Receive or Manual Receive.
ξAuto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” on page
ξManual Receive: Perform the operation under “To perform manual receive” on page
Auto Receive
ξWith Auto Receive, the watch performs the receive operation each day automatically up to six times (up to five times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Home City time). When any receive operation is successful, none of the other receive operations for that day are performed.
ξThe receive operation is not performed if a calibration time is reached while you are configuring settings.
