What is the range for receiving the time calibration signal?
Click the following to get answer.
Why is the time as set by the time calibration signal slightly different from the time indicated by the time signal on the TV, radio, etc.?
After the watch receives the time calibration signal, it performs various calculations to determine the current time. These calculations can cause the time setting to be off by up to one second.
Why is the time as set by the time calibration signal one hour off?
This is because the watch is not making allowances for Daylight Saving Time (summertime). Change the watch’s DST setting* to “Auto DST”, and it will adjust the hour setting automatically. Note that you should turn off the DST setting if you are in an area where Daylight Saving Time (summer time) is not used.
* For models that do not have the “Auto DST” setting: DST setting can only be turned on/off manually.
Why is the time as set by the time calibration signal wrong?
Your Home City code setting is probably incorrect for your current location. Change your Home City code so it matches the time zone where you are currently located.
