Maintenance
1. Battery Replacement
When the watch display becomes dim or stops functioning, the battery may need replacement. It is recommended to have the battery replaced by a qualified watch technician to ensure proper sealing and maintain water resistance.
2. Water Resistance
Your Armitron Sport 20/4942 watch is water resistant up to 165 feet (50 meters). This rating means the watch is suitable for splashes, rain, and brief immersion in water. It is not suitable for swimming, diving, or prolonged water activities. Do not operate buttons while the watch is submerged in water, as this can compromise the water seal.
3. Cleaning
To clean your watch, wipe it gently with a soft, damp cloth. Avoid using harsh chemicals, solvents, or abrasive cleaners, as these can damage the watch case, crystal, or resin strap.
Troubleshooting
- Digital Display is Blank or Dim: The battery may be low or depleted. Refer to the "Battery Replacement" section.
- Buttons are Unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a common feature for this model). Try pressing buttons firmly. If unresponsive, a battery issue or internal malfunction may be present.
- Time is Inaccurate: Re-set the time following the "Digital Time and Date Setting" and "Analog Time Setting" instructions. If inaccuracy persists, the battery may be weak or the movement may require service.
- Water Inside Watch: Immediately take the watch to a qualified technician for inspection and repair to prevent further damage.
