How to operate module 5634

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 (on a screw-in crown, unscrew it first), then pull the crown out to the second click.
  2. Turn the crown to set the time, minding a.m. and p.m. Go four or five minutes past the time you want, then turn back to it.
  3. Push the crown back in on a time signal to start the watch; on a screw-in crown, screw it fully back in.
  4. To set the day, pull the crown out to the first click (on a screw-in crown, unscrew it first), turn it away from you until the day is right, then push it back in (and screw it in).

Good to know

Some water resistant models have a screw-in crown: turn it towards you to unscrew it before pulling it out, do not pull it too hard, and screw it fully back in afterwards. The watch is not water resistant while the crown is unscrewed.

The day indicator counts 31 days in every month; move it on by hand after shorter months.

Do not change the day between 9 p.m. and 1 a.m., or it may not change correctly at midnight.

If the watch had a spacer around the crown when new, remove it before setting the time.

Zero the stopwatch hands

  1. Stop the stopwatch with A if it is running, press B to reset it, and check whether the stopwatch minute hand points to the L mark and the stopwatch second hand to 12 o'clock.
  2. If not, wait until the second hand reaches 12 o'clock (on a screw-in crown, unscrew it first), then pull the crown out to the second click.
  3. Hold A for at least two seconds: the stopwatch minute hand turns to show it can be set. If it is not on L, press B to move it there (hold for fast).
  4. Press A: the stopwatch second hand turns once round. If it is not on 12 o'clock, press B to move it there (hold for fast).
  5. Push the crown back in; on a screw-in crown, screw it fully back in.
  6. The watch stops while the crown is out, so set the time again afterwards.

Stopwatch

  1. Press A to start, A to stop, and A again to carry on.
  2. When it is stopped, press B to reset it.
  3. For a split time, press B while it runs; press B again to release it.
  4. For two finishes: start with A, press B when the first finishes, A when the second finishes, then B to see the second time and B again to reset.

Good to know

It counts in seconds up to 59 minutes 59 seconds and stops by itself at 60 minutes.

Do not use the stopwatch with the crown pulled out.

The stopwatch minute hand also shows the battery level (H, M, L). After a reset it goes back to the battery level when you press B or after 60 seconds without operation.

System reset

  1. Pull the crown out to the second click (on a screw-in crown, unscrew it first).
  2. Hold A and B together for at least two seconds.
  3. Push the crown back in (and screw it in): the second hand starts to move.
  4. Set the time and day again, and zero the stopwatch hands if needed.

Good to know

Use this only if the hands move abnormally, or the second hand does not move in one-second steps even after a full charge.

The watch stops while the crown is out.
