Operation Guide 5631

Shifting the Hands

Hand shift moves the hands out of the way for easy viewing of display information.

1. While holding down (L), press (D).

●

This will shift the analog hands to allow easy viewing of display information.

2. To return the hands to their normal

timekeeping positions, hold down (L) as you press (D) again, or press (D) to change to another mode.

Note

●

If you leave the watch with its hands shifted and do not perform any operation for about one hour, the hands will resume normal timekeeping automatically.

Important!

●

Depending on light intensity and local conditions, the watch may become hot to the touch when exposed to light for charging. Take care to avoid burn injury after charging. Also, avoid charging the watch under hightemperature conditions like the ones described below.

ー　

On the dashboard of a vehicle parked in the sun

ー　

Near an incandescent light bulb or other source of heat

ー　

Under direct sunlight or in other hot areas for long periods

● Checking the Charge Level

In the Timekeeping Mode, the current charge level is indicated by the mode hand.

● Remaining Charge and Dead Battery

You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.

Important!

●

Should the battery go low or go dead, expose the face (solar panel) to light as soon as possible.

Note

●

Exposing the watch face to light after the battery goes dead will cause the [CHARGE] indicator to appear and the second hand to rotate counterclockwise until it stops at second 57. This indicates charging has started.

Low Battery Power

The second hand jumps at two-second intervals.

Solar Charging

This watch runs on power supplied from a rechargeable (secondary) battery that is charged by a solar panel. The solar panel is integrated into the face of the watch, and power is generated whenever the face is exposed to light.

●

Charging the Watch

When you are not wearing the watch, put it in a location where it is exposed to bright light.

While you are wearing the watch, make sure that its face (solar panel) is not blocked from light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Dead Battery

All hands are stopped.

A　Good (high charge)

B　Good (medium charge)

C　Low Battery

Mobile Link Precautions

● Legal Precautions

●

This watch complies with or has received approval under the radio laws of various countries and geographical areas. Using this watch in an area where it does not comply with or has not received approval under applicable radio laws may be a criminal offense. For details, visit the CASIO Website.

https://world.casio.com/ce/BLE/

●

Use of this watch inside of aircraft is restricted under the aviation laws of each country. Be sure to follow the instructions of airline personnel.

● Precautions when using Mobile Link

●

When using this watch in combination with a phone, keep the watch and phone close to each other. A range of two meters is recommended as a guideline, but the local environment (walls, furniture, etc.), the structure of a building, and other factors may require a much closer range.

●

This watch can be affected by other devices (electrical devices, audio-visual equipment, office equipment, etc.) In particular, it can be affected by operation of a microwave oven. The watch may not be able to communicate normally with a phone if a microwave oven is operating nearby. Conversely, this watch may cause noise in radio reception and the video image of a TV.

●

Bluetooth of this watch uses the same frequency band (2.4 GHz) as wireless LAN devices, and use of such devices in close proximity of this watch may result in radio interference, slower communication speeds and noise for the watch and the wireless LAN device, or even communication failure.

● Stopping Radio Wave Emission by This

Watch

The watch is emitting radio waves whenever the second hand is pointing to [READY] or [CONNECT]. In addition, the watch also connects phone automatically four times a day to adjust its time setting.

When in a hospital, on an aircraft, or in any other area where the use of radio waves is not allowed, use the operation below to stop radio wave generation.

●

Stopping Radio Wave Generation

Press any button to terminate the Bluetooth connection.

●
