Water Resistance (WR30M)
Your Zerodis WR30M Digital Sports Watch is designed with WR30M water resistance. This means it is suitable for daily use, resistant to splashes, rain, and brief immersion in water. It is not suitable for showering, swimming, diving, or any activities involving high-pressure water or prolonged submersion. Do not operate buttons while the watch is wet or submerged.
Maintenance
Cleaning
Wipe the watch regularly with a soft, dry cloth. For stubborn dirt, use a slightly damp cloth and then dry thoroughly. Avoid using chemical cleaners, solvents, or abrasive materials, as these can damage the watch's finish and seals.
Battery Replacement
The watch uses one LR1130 1.5V 80mAh battery. When the display becomes dim or functions become erratic, the battery may need replacement. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and water resistance.
Storage
When not in use for extended periods, store the watch in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
- Display is blank or dim: The battery may be low or depleted. Replace the battery.
- Time is incorrect: Re-set the time following the instructions in the "Setting Time and Date" section. Ensure the 12/24 hour format is set correctly.
- Buttons are unresponsive: Ensure the watch is not wet. If the issue persists, a reset may be needed (consult a professional if no external reset button is visible).
- Water inside the watch: Immediately take the watch to a professional for inspection and repair to prevent further damage.
