Q. How do you set tide graph location on GPRB1000?
A. This can be accomplished using the G-SHOCK Connected app. Open G-SHOCK Connected, tap the gear icon in the upper right corner to go to settings, then tap "CASIO GPR-B1000". This will bring up a menu with several settings. Under "WATCH", tap "Set the location of the tide graph display". You should see a map, with red dots designating the locations that can be selected. Tap a dot, and look for an option at the bottom of the screen that says "Set this location in your watch". Tap that button to send the information to the watch.
