Instructions for a Baby-G watch can be found on the Casio website by searching the watch product number, searching Baby-G support and clicking on Manual from the menu or searching on the Casio support page using the watch's 3- or 4-digit module number located on the back cover of the watch. The watch manuals are available to download in PDF format.
The time on the Baby-G watch is accessed using a time calibration signal. To ensure the accuracy of the timepiece, use the setting "Auto DST" to adjust for daylight savings time and set the home city code setting to the correct time zone. Time calibration signal reception can take up to 12 minutes.
