4. Press A to exit the setting mode.
Exiting a setting mode will normally cause the hands to return to regular
timekeeping automatically. However, if you manually move the hands (page
E-79) and then enter a setting mode, they will not return to regular timekeeping
automatically when you exit the setting mode. In this case, you will need to
return the hands to their normal positions manually (page E-80).
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 "Specifications" (page E-92).
