Care and Maintenance

• Charging: Regularly expose your watch to light to ensure its Tough Solar battery remains charged. Avoid prolonged storage in dark places.
• Water Resistance: While your watch is 20 ATM water resistant, avoid operating buttons or the crown (if applicable) when the watch is wet or submerged to prevent water ingress.
• Cleaning: Clean the watch case and band with a soft cloth and water. For resin bands, a mild soap can be used. Avoid harsh chemicals or solvents.
• Temperature: Avoid exposing the watch to extreme temperatures, both hot and cold, as this can affect its performance and battery life.

Troubleshooting

• Time Not Syncing:
  • Ensure your Home City is correctly set.
  • Attempt manual synchronization in an open area, preferably near a window, away from electronic devices that might interfere with the signal.
  • Check if the watch is in a region that receives Multi Band 6 signals.
• Low Battery Indicator: If the display shows 'CHG' or is dim, expose the watch to bright light for an extended period to fully charge the Tough Solar battery.
• Display Readability: In very low light, activate the backlight using the 'LIGHT' button. Ensure Auto EL is enabled if you prefer automatic illumination.
• Buttons Not Responding: If buttons are unresponsive, ensure the watch is not in a locked mode (if applicable) or that the battery is not critically low.
