Water Resistance

Important Information: Read Before Use

For all categories of watches, the following actions are prohibited while submerged in water:

• Pressing buttons
• Adjusting the crown
• Unscrewing the crown (if applicable)

If the watch is exposed to salt water, rinse it thoroughly with fresh water and dry it completely. Do not wear watches with leather straps while swimming, and avoid prolonged contact of leather straps with water.

Watches are classified into water resistance levels (I to V) based on their protection against water. Refer to the table below to determine the appropriate usage for your watch.

Notes:

• Level I: Watches are not water-resistant. Avoid any contact with moisture.
• Level II (WR - Water Resistant): Indicates water resistance according to ISO 2281. Brief contact with water will not cause problems.
• Level III (5 Bar / 50 meters): Watches can withstand water pressure as indicated and can be used during showers and brief swimming.
• Level IV (10 Bar / 100 meters): Watches can be used during normal swimming and snorkeling.
• Level V (20 Bar / 200 meters): Watches can be used for scuba diving (excluding depths requiring helium-oxygen mixtures).

Condensation: Under conditions of rapid temperature changes, slight condensation may form on the inside of the glass. This is a normal physical phenomenon and not a defect.

Disclaimer: CASIO COMPUTER CO., LTD. is not responsible for any damage that may occur from the use of these watches and does not accept claims from third parties.

Crown Operation

Your watch may differ slightly from the illustrations in this manual.

Note on Screw-Lock Crowns:

Some water-resistant models are equipped with a screw-lock crown. To pull out the crown, you must first unlock it by turning it in the direction indicated by the [Rotation Symbol] ?. Do not use excessive force when pulling out the crown, as this may cause damage.

Important: The watch is no longer protected against water and moisture when the crown is pulled out. After performing any necessary operations with the crown, always return it to its original position and lock it.

Watches with Backlight

• Press and hold the L button to illuminate the watch face.
• The backlight duration varies by model, lasting 2-3 seconds, 1 second, or until the L button is released (Module 5577).
• The backlight is provided by electroluminescent (EL) elements or LEDs. EL elements may lose brightness after prolonged use.
• Frequent use of the backlight reduces battery life.
• Activating the backlight for extended periods or with a low battery charge may temporarily stop the watch hands from moving.
