Maintenance
Cleaning
Wipe the watch with a soft, dry cloth to remove dirt and moisture. For stubborn dirt, use a soft cloth dampened with water and a mild neutral detergent, then wipe dry. Avoid using volatile agents like thinner or benzine, as they may damage the resin components.
Water Resistance
The AE-1700H is 100-meter water resistant (10 ATM). This means it is suitable for swimming, snorkeling, and active water sports. Do not operate buttons while the watch is wet or submerged. Avoid exposing the watch to hot water or steam, as this can compromise the water resistance seals.
Battery Replacement
The watch uses a CR2032 battery with an approximate 10-year life. When the display becomes dim or functions become erratic, it may be time for a battery replacement. It is recommended to have the battery replaced by an authorized Casio service center to ensure proper sealing and maintain water resistance.
Troubleshooting
Display is Blank or Dim
- Cause: Low battery.
- Solution: Replace the battery. Refer to the "Battery Replacement" section.
Buttons are Unresponsive
- Cause: Watch may be in a frozen state or water ingress.
- Solution: Try pressing all buttons simultaneously for a few seconds to attempt a soft reset. If the issue persists, or if the watch was recently exposed to water, contact Casio customer support.
Time is Incorrect
- Cause: Time settings were accidentally changed, or battery is low.
