Casio support FAQ

Common questions about manuals, registration, and support for this brand.

  • Where can I find digital manuals for my Casio watch?

    You can download PDF manuals for Casio watches by entering the 4-digit module number (found on the back of the watch case) on the official Casio support website or by browsing the Casio category on Manuals.plus.

  • How do I reset my Casio scientific calculator?

    For many models like the ClassWiz or fx series, press Shift followed by 9 (Reset), then select 'Initialize All' (usually option 3), and confirm with '=' (Yes) and 'AC'. Check your specific model's manual for exact keystrokes.

  • How do I change the time on a G-Shock watch?

    Typically, hold the top-left 'Adjust' button until the city code flashes. Use the 'Mode' button to cycle through settings (DST, 12/24h, Hour, Minute) and the right-side buttons to adjust the values. Press 'Adjust' again to exit.

  • What does 'Water Resist' mean on my Casio watch?

    'Water Resist' without a depth rating usually means it can withstand splashes or rain. 50M (5 BAR) is suitable for swimming, while 100M (10 BAR) and 200M (20 BAR) are suitable for water sports and diving (excluding scuba).
