Casio 3069 Watch User Manual


 
E-130
Though this watch is designed to receive both time data (hour, minutes,
seconds) and date data (year, month, day), certain signal conditions can
limit reception to time data only.
If you are in an area where proper time calibration signal reception is
impossible, the watch keeps the time with the precision noted in
Specifications.
If you have problems with proper time calibration signal reception or if the
time setting is wrong after signal reception, check your current city code,
DST (summer time) (page E-117), and auto receive settings (page E-27).
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 (page E-13).
