How to operate module 5340

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 day

  1. Wait until the second hand reaches 12 o'clock, then pull the crown out to the second click to stop it.
  2. Turn the crown to set the hands, going four or five minutes past the time you want and then turning back to it.
  3. Push the crown back in on a time signal to restart the watch.
  4. To set the day, pull the crown out to the first click, turn it to set the day, then push it back in.

Good to know

Do not set the day between 9:00 p.m. and 1:00 a.m., or it may not change over the next day.

If the crown screws down, unscrew it before pulling it out and screw it back in fully afterwards; the watch is not water resistant while it is loose.
