Casio module 5636

Good to know

From any other mode, hold C for at least one second to go to the Calendar Mode.

Set the Home City time zone first, or the time will be wrong after the watch takes it from a time signal.

The watch sets itself from a paired phone running CASIO WATCHES, or, when it has not connected to the phone for more than a day or is not paired, from a time calibration signal (Japan, China, United States, U.K., Germany) received between midnight and 5:00 a.m.; setting it by hand is for when neither works.

To take the time from a paired phone now, hold D for at least 0.5 seconds in the Calendar Mode and let go when the second hand points to C.

To receive a time signal now (only when not paired with a phone), put the watch near a window with 12 o'clock towards it and hold D for at least 0.5 seconds in the Calendar Mode until the second hand points to RC; reception takes about 2 to 10 minutes, up to 20.

Changing the day makes the mode hand turn several times.

Turning the crown quickly several times moves the hands fast; turn it the other way or press any button to stop them.

The crown screws down: unscrew it (towards you) before pulling it out, and screw it back in (away from you) as you push it in, or the watch may lose water resistance.

Good to know

AT is offered only when the Home City time zone is one where a time signal can be received; with AT the watch switches at the first time signal it receives after summer time starts or ends.

With a paired phone, the summer time setting can also be made in CASIO WATCHES (Auto, OFF or ON); with Auto the watch switches by itself.

Setting the time by hand on the watch cancels the automatic switching set in the app.

The Dual Time has its own summer time setting: pull the crown out to the first click instead and hold B for at least one second.

Good to know

Paired with a phone, the watch takes the time zone of the phone when you travel.

To set the Dual Time on the small hands, pull the crown out to the first click instead and turn it to choose the Dual Time zone (New York, -5, is at the 55-second position), then push it back in.

To swap your Home City time with the Dual Time, hold B for at least three seconds in the Calendar Mode.

A World Time City chosen in CASIO WATCHES, out of about 300 cities, is shown on the small hands; auto time adjustment does not run for 24 hours after a swap made in the app.

The crown screws down: unscrew it (towards you) before pulling it out, and screw it back in (away from you) as you push it in, or the watch may lose water resistance.

Good to know

In the Alarm Mode, press D to switch the alarm on or off; the second hand points to ON or OFF.

The alarm beeps for 10 seconds; press any button to stop it.

The alarm does not sound when the battery is low or in Level 3 power saving.

You can also set the alarm with the CASIO WATCHES app.

Good to know

Strong magnetism or impact can knock the hands or the day indicator out of alignment.

In the mode hand step the crown moves the mode hand at most 180 degrees either way and the day indicator only slightly.

Changing the day makes the mode hand turn, in some cases for about 5 minutes.

If the crown stays out for about 30 minutes without an operation, adjustment is disabled: push the crown in and start again. Pushing it in part way through keeps what you have aligned so far.

With a paired phone, the hands can also be aligned with the CASIO WATCHES app.

Good to know

The light goes off by itself when the alarm starts to sound, does not work while the hands move at high speed, and may flicker as it turns on or off.

Good to know

It counts in 1-second steps up to 23 hours 59 minutes 59 seconds.

Good to know

The start time is set in 1-minute steps up to 24 hours; for 24 hours, put the small hour and minute hands on 12 o'clock so the small 24-hour hand is on 24.

At zero it beeps for 10 seconds; press any button to stop it. It does not beep when the battery is low.

You can also set the start time with the CASIO WATCHES app.

Good to know

This returns the watch settings, the stopwatch, the timer and the alarm to their factory defaults.

To delete the pairing information from the watch, pull the crown out to the second click in the Calendar Mode, hold D for at least 10 seconds until the second hand points to C, then push the crown back in. Unpair in the CASIO WATCHES app as well; on an iPhone, also remove the watch in the phone's Bluetooth settings.
