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 the

light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

Important!

●

Depending on light intensity and local conditions, 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

Power Saving

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 5:50 a.m. will cause the second hand to stop, and the watch to enter Level 1 power saving. If the watch is left in this condition for six or seven days, all hands will stop and the watch will enter Level 2 power saving.

Level 1 : Basic timekeeping functions are operational.

Level 2 : Only the day indicator is operational.

Note

●

Note

that the watch also may enter the power saving state if its face is blocked from light by your sleeve while you are wearing it.

●

The watch will enter power saving from the Timekeeping Mode only.

●

Recovering from Power Saving Operation

Press any button, perform a crown operation, or place the watch in a well-lit area to recover from power saving.

Connecting with a Phone

●

Triggering Immediate Time Adjustment

The watch will synchronize its time setting with that of an online time server whenever a connection is established between it and a phone. Perform the operation below to connect

the watch with a phone whenever you want to have the watch’s time setting synchronized with that of an online time server.

●

The connection is terminated automatically after time adjustment is complete.

Note

●

If the watch time is adjusted by connection with a phone, the watch’s Home City setting will change to the city that is being used for the phone’s time

setting. If summer time is in effect in the city being used for the phone’s time setting, the watch’s time setting will also become summer time.

●

If the watch does not indicate the correct time even if it is able to connect with a phone, adjust the hand and day indicator positions.

Time Adjustment Using a Time Calibration Signal

Overview

The watch’s time and day settings can be adjusted in accordance with a received time signal.

Important!

●

In order to make it possible for the current time setting to be adjusted correctly based on time calibration signal reception, you need to specify the

time zone where you are using the

watch.

●

However, if the watch was unable to connect with a phone even once for time adjustment during the previous day while connection with a phone is being used, it will automatically try to receive a time calibration signal.

Note

●

Areas where time calibration signal reception is supported are limited. When

the watch in an area where time calibration signal reception is not possible, connect with a phone to adjust time and day settings.

Time Calibration Signal Reception

Ranges

●

If the watch does not indicate the correct time even after it receives a time calibration signal, correct the hand and day indicator positions.

U.K. (MSF) and German (DCF77) Time Calibration Signal

Note

●

Even if you are within the normal reception range of a time calibration signal, reception may be made impossible by the following factors: geographic contours, weather, the season, the time of day, wireless noise.

●

Reception

takes anywhere from about two minutes to about 10 minutes. It can take as long as 20 minutes.

●

If the watch connects with a phone and adjusts its time setting, the watch will not perform auto receive of a time calibration signal for the rest of that day or the next day.

●

Reception

takes anywhere from about two minutes to about 10 minutes. It can take as long as 20 minutes.

●

Time calibration signal reception is better at night than during the day.

Signal Reception Precautions

●

When the watch is unable to adjust its time in accordance with a calibration signal for some reason, average timekeeping accuracy is within ±15 seconds per month.

●

Note that an internal decoding process the watch performs after it receives a signal

cause the time setting to be slightly off

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

offense. For details, visit the CASIO

criminal 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.
