Operating Instructions

Basic Mode Navigation

Press the 'MODE' button (usually bottom left) to cycle through the watch's various modes: Timekeeping, Compass, Altimeter/Barometer, Thermometer, Step Counter, Stopwatch, Countdown Timer, Alarm, and World Time.

Quad Sensor Functions

• Digital Compass: Press the 'COMP' button to activate the compass. The second hand will indicate North, and the digital display will show the direction and bearing.

• Step Counter: The watch automatically counts your steps using a 3-axis acceleration sensor. View your step count in the dedicated mode or via the G-SHOCK Connected app.

Note: Sensor readings can be affected by environmental conditions and magnetic fields. Calibrate sensors regularly for optimal accuracy, especially the compass and altimeter, using the G-SHOCK Connected app or manual calibration procedures.

Maintenance

Cleaning

Regularly clean your watch to prevent dirt and grime buildup, especially after exposure to mud or saltwater.

• Wipe the watch with a soft, dry cloth.
• For stubborn dirt, use a soft brush and mild soap with water. Rinse thoroughly with fresh water and dry completely.
• After exposure to saltwater, rinse the watch thoroughly with fresh water.

Water Resistance

Your watch is rated for 200-meter water resistance. This means it is suitable for showering, swimming, and snorkeling. Do not operate buttons while the watch is submerged in water or wet, as this can compromise the water resistance.

Battery Replacement

The watch uses one CR123A battery. When the battery power is low, the display may dim or functions may become unstable. Battery replacement should ideally be performed by an authorized Casio service center to ensure proper sealing and water resistance integrity.

Troubleshooting

• Incorrect Time: Ensure the watch is paired with your smartphone and the G-SHOCK Connected app is running. If not using Mobile Link, manually adjust the time.
• Inaccurate Sensor Readings: Calibrate the compass and altimeter regularly, especially after significant changes in location or environment. For temperature, remove the watch from your wrist.
• Bluetooth Connection Issues:
  • Ensure Bluetooth is enabled on your smartphone.
  • Check if the watch is within range of your phone.
  • Restart both the watch (by removing and reinserting the battery, if comfortable, or performing a factory reset if available) and your smartphone.
  • Unpair and re-pair the watch through the G-SHOCK Connected app.
• Display is Blank or Dim: This may indicate a low battery. Replace the CR123A battery.
• Buttons Unresponsive: Ensure the watch is not in a locked mode. If the issue persists after a battery change or restart, contact customer support.
