How to operate module 5601

Short steps in our words. The buttons are lettered as in Casio's operation guide, where each task's page is given.

Set the time and date

  1. In the Timekeeping Mode, hold D for at least two seconds and let go when the Home City name shows (SET shows first).
  2. Press D: the seconds flash.
  3. Press E to step through the settings: seconds, hours, minutes, year, month, day, then back to the seconds.

  6. Press D to leave the setting screen.

Good to know

Set the time by hand only when the watch cannot connect with a phone. When it is paired with CASIO WATCHES and left in the Timekeeping Mode, it connects and corrects its time by itself at around 12:30 a.m., 6:30 a.m., 12:30 p.m. and 6:30 p.m.

To correct the time from the phone now, keep the phone within one meter and press B: TIME flashes, then OK shows and the time is set. This works from any mode.

Resetting the seconds between 30 and 59 adds one minute.

12/24-hour format: hold D until the Home City name shows, press E four times (12H or 24H flashes), press A to switch, then press D twice.

After the time is set by hand on the watch, auto time correction from the phone does not run for 24 hours.

Auto time adjustment on or off (for example on an aircraft): hold D until the Home City name shows, press E five times (RCV shows), press A to pick ON or OFF, then press D twice.
