5. Troubleshooting

• Display is blank or dim: Check the battery. Replace if necessary.
• Stopwatch resets unexpectedly during timing: This can sometimes occur due to low battery or a temporary electrical glitch. Try replacing the battery. If the issue persists, ensure buttons are not being pressed inadvertently.
• Buttons are unresponsive: Ensure the stopwatch is not in a locked mode (if applicable, check manual for specific lock features). If wet, ensure it is completely dry. If still unresponsive, try replacing the battery.
