Radio-controlled Atomic Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time setting.
• Even if a receive operation is successful, certain conditions can cause the time setting to be off by up
to one second.
• 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.
• If you are in an area where signal reception is not possible, the watch keeps time with the precision
noted in "Specifi cations".
• The receive operation is disabled under any of the following conditions.
– While power is at Level 3 (L) or lower
– While the watch is in the power recovery mode
– While a sensor operation is being performed
– When the watch is in the function sleep state ("Power Saving")
– While a countdown timer operation is in progress
• A receive operation is cancelled if an alarm sounds while it is being performed.
• The Home City setting reverts to the initial default of TYO (Tokyo) whenever the battery power level
drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the
Home City to the setting you want.

• Determine your current location using the watch and a map
• View the barometric pressure and temperature at your current location
• View a graph of barometric pressure readings
• View the altitude at your current location
• Determine the altitude differential between two locations (reference
point and current location)
• Record an altitude reading with the measurement time and date

4. Use A to cycle through the DST settings in the sequence shown below.
Auto DST (AUTO)
• The Auto DST (AUTO) setting will be available only when a city code that supports time calibration
signal reception is selected as the Home City. While Auto DST is selected the DST setting will be
changed automatically in accordance with time calibration signal data.
• Note that you cannot switch between standard time and daylight saving time (DST) while UTC is
selected as your Home City.
5. After all the settings are the way you want, press E twice to return to the Timekeeping Mode.
• The DST indicator appears to indicate that Daylight Saving Time is turned on.
Note
• After you specify a city code, the watch will use UTC* offsets in the World Time Mode to calculate
the current time for other time zones based on the current time in your Home City.
* Coordinated Universal Time, the world-wide scientifi c standard of timekeeping.
The reference point for UTC is Greenwich, England.
• Selecting some city codes automatically makes it possible for the watch to receive the time
calibration signal for the corresponding area. See "Radio Controlled Atomic Timekeeping" for
details.
