Onderhoud
Skoonmaak
Wipe the stopwatch with a soft, dry cloth. For stubborn dirt, use a slightly damp lap met sagte seep, en vee dan droog. Vermy harde chemikalieë of skuurmiddels.
Waterweerstand
The Casio HS-70W-1JH is designed with 5 ATM water resistance. This means it is suitable for everyday use and can withstand splashes, rain, and brief immersion in water. However, it is not recommended for swimming, diving, or operating buttons underwater.
Battery vervanging
When the display becomes dim or functions become erratic, the battery may need replacement. This model typically uses a CR2032 lithium battery. Battery replacement should ideally be performed by a qualified technician to ensure proper sealing and water resistance. If replacing yourself, carefully open the back cover, replace the battery with the correct type, and ensure the gasket is properly seated before re-securing the cover.

Probleemoplossing
- Skerm is leeg of dof:
Dit dui gewoonlik op 'n lae battery. Vervang die battery soos beskryf in die Onderhoud-afdeling.
- Knoppies reageer nie:
Check for dirt or debris around the buttons. If the issue persists after cleaning, a battery replacement might be necessary, or there could be an internal malfunction. Avoid forcing buttons.
- Verkeerde tyd vertoon:
Re-set the time according to the "Initial Power-On and Time Setting" instructions in the Setup section.
- Stopwatch not starting/stopping:
Ensure you are in Stopwatch mode. If the issue continues, try a battery replacement or a full reset (if a reset pinhole is available, consult the official Casio manual).
