Operation Guide 5423
ENGLISH
Congratulations upon your selection of this CASIO watch.
This watch does not have a city code that corresponds to the UTC offset of –3.5 hours. Because of this, the radio-controlled atomic timekeeping function will not display the correct time for Newfoundland, Canada.
Note that CASIO COMPUTER CO., LTD. assumes no responsibility for any damage or loss suffered by you or any third party arising through the use of your watch or its malfunction.

2. Check the Home City and the daylight saving time (DST) setting.
Use the procedure under “To configure Home City settings” (page E-32) 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, time, and date settings in the Timekeeping Mode. Make sure you configure these settings correctly.
3.Set the current time.

Operation Guide 5423
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 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.
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. Make sure that the watch is exposed to bright light whenever possible.

x 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.

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.

x The watch will not enter a sleep state while it is in the Stopwatch Mode.
E-14
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-36) 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.

x If the x Second Hand is moving normally in onesecond intervals, power is at Level 1.
x If the x Second Hand is moving at two-second intervals, power is at Level 2, which is quite low (Low battery alert). Expose the watch to light as soon as possible so it can charge.

|
Important!
x The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
x 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 toggle the Home City time between standard time and daylight saving time” (page E-34) for information about how to do this.

x Using this watch in a country covered by a time calibration 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.Confirm that the watch is in the Timekeeping Mode. If it isn’t, hold down Cfor about two seconds to enter the Timekeeping Mode.
2.Place the watch in a location where signal reception is good.
x Position the watch as shown in the nearby illustration, with 6 o’clock pointed towards a window. Make
sure there are no metal objects nearby.
x Signal reception normally is better at night.
E-21
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” on page E-23 for details.
x Manual Receive: Perform the operation under “To perform manual receive” on page E-24.
Auto Receive
x With 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 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 configuring settings.
|
|
E-23 |
x |
3. The receive operation is complete when the x Second |
|
|
|
Hand moves to Y (YES) or N (NO) for about five |
|
|
|
|
|
seconds, and then resumes regular timekeeping. |
|
|
x You can return to the Timekeeping Mode manually by |
|
|
pressing Awhile the x Second Hand is pointing to |
|
|
Y (YES) or N (NO). |
|
|
x When the receive operation is successful, the watch |
|
|
30 |
adjusts the time setting accordingly. It does not adjust the setting if the operation failed.
Note
x To interrupt a receive operation and return to the Timekeeping Mode, press any button.
E-25
Radio-controlled Atomic Timekeeping Precautions
x Strong electrostatic charge can result in the wrong time setting.
x Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.
x The watch is designed to update the date and day of the week automatically for the period January 1, 2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.
x If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications” (page E-69).
x The receive operation is disabled under any of the following conditions.
−While power is at Level 2 or lower (page E-11)
−When the watch is in the function sleep state (Power Saving, page E-14)
