To perform a crown operation, pull it outdo the first or second click and then rotate it. Do not pull the crown with too much force.
First click

Second click

Important!

• To prevent loss of water resistance and/or damage due to impact, be sure to screw the crown in by rotating it away from you as you push it in.

• When pushing the crown back in, take care not to apply too much force.

• Fast Forward/Fast Reverse
  After pulling out the crown, rotating it quickly IN succession in either direction will cause the hands to move forward or backfat high speed.
  While the hands are moving forward at high speed, quickly rotating the crown in succession again will increase the speed even further.

• Stopping Fast Forward/Fast Reverse
  Rotate the crown in the direction opposite that of the ongoing operation or press any button.

Note

• If you do not perform any operation for about two minutes after pulling out the crown, crown operations will automatically become disabled. If that happens, push the crown back in and then pull it out again.

Hand and Day Indicator Movement

• Day of the Week and Day Indicator Operation
  Changing the day setting of the watch will also cause the day of the week hand to move in conjunction with the day.

• Day

  • It can take anywhere from about 10 to 40 seconds for the day indicator to change after timekeeping reaches midnight. The day of the week hand will move as the day indicator changes.
  • The day may not be indicated correctly while the watch’s crown is pulled out.

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

• Charging the Watch
  When you are not wearing the watch, put it in allocation 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.

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 bum injury after charging. Also, avoid charging the watch under high- temperature conditions like the ones described below.

  • On the dashboard of a vehicle parked in the sun
  • Near an incandescent light bulb or other source of heat
  • Under direct sunlight or in other hot areas for long periods

• Checking the Charge Level
  Immediately after you press (C) tapetum to the Timekeeping Mode, the day of the week hand will indicate the battery charge level. After a short while, the day of the week hand will fretum to indicating the current day of the week. 1. Good (high charge)
  2. Good (medium charge)
  3. Low Battery

• 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) tonight’s soon as possible.

Note

• Exposing the watch face to light after the battery goes dead will cause the second hand to revolve counterclockwise until it stops at second 57. This indicates charging has started.

Low Battery Power
The second hand jumps at two-second intervals.

Dead Battery
All hands and the day indicator are stopped.

• Charging Time Guidelines
  The table below shows guidelines for approximate charging times.
  Charging Times Required for 1 Day of Operation

Times Required to Achieve Next Charge Level

Charge Level 1 :
Time from dead battery until watch operation starts.
Charge Level 2 :
Time from watch operation start until a full charge.
Light Intensity

1. Sunny day, outdoors (50,000 lux)
2. Sunny day, near a window (10,000 lux)
3. Overcast day, near a window (5,000 lux)
4. Indoor fluorescent lighting (500 lux)

• Power Saving
  Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 am. will cause the second hand to stop, and the watch will enter Level 1 power saving. If the watch s 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 fits 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 or place the watch in a well it area to recover from power saving.

Auto Time Adjustment
Your watch can receive time calibration signals and connect with a phone to obtain information that it uses to adjust its date and time setting.

• First Use of the Watch
  Immediately after purchasing the watch, it will acquire GPS location information and configure a Home City based on your current location.
  Acquiring GPS Position Information Manually

GPS signal (location information)

• Normal Use of the Watch
  Your watch automatically receives a time calibration signal or GPS signal (time information) regularly each day and adjusts its time setting. This means its time setting is always accurate without the need for any adjustment by you.

Getting Ready
Enter the Timekeeping Mode.
Navigating Between Modes

Place the watch near a window or some other location appropriate for signal reception.

• The second hand points to [RC] while time calibration reception in progress.
• When the receive operation is successful, the time and day settings will be adjusted automatically.

Note

• Reception takes anywhere from about twominutes to about 10 minutes. It can take as long as 20 minutes.

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 may cause the time setting to be slightly off (by less than one second).
  GPS signal and time calibration signal reception will not be possible under any of the watch conditions described below.
  ~While battery power is low
  ~While the watch s in the Airplane Mode, Stopwatch Mode, Timer Mode, o Alarm Mode

  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, o even communication failure.

Stopping Radio Wave Emission by This Watch
The watch is emitting radio waves whenever the second hand is pointing to [C.
Even if the second hand is not pointing at [C], the watch will automatically attempt to connect with a phone four times a day to adjust its time settings.
When in a hospital, on an aircraft, or in any other area where the use of radio waves s not allowed, use the operation below to stop radio
Wave generation.

• Stopping Radio Wave Generation Press (C) to terminate the Bluetooth connection.
• Disabling Auto Time Adjustment Configure CASIO WATCHES settings to disable synchronization between the watch and phone.
