Setup
Initial Charging
Before initial use, expose the stopwatch to bright light (natural sunlight or strong artificial light) for several hours to ensure it is fully charged. A full charge provides approximately 6 months of operation, or up to 24 months in power-saving mode without light exposure. The display may indicate a low battery or remain blank if not sufficiently charged.
Time and Date Setting
The stopwatch features a full auto-calendar function. Upon sufficient charging, the time and date should set automatically. If manual adjustment is required, refer to the full manufacturer's guide for specific button sequences to enter time/date setting mode and make adjustments.
Contrast Adjustment
The display contrast can be adjusted for optimal visibility under different lighting conditions. To adjust, locate the contrast setting option within the device's menu or by pressing a specific button combination. Consult the full manufacturer's manual for detailed instructions on accessing and modifying this setting.

Operating Instructions
Stopwatch Function
- Start: Press the START button to begin timing.
- Stop/Pause: Press the STOP button to pause the timing. Press START again to resume.
- Reset: While the stopwatch is stopped, press the RESET button to clear the time and return to zero.
The stopwatch can measure up to 100 hours with an accuracy of 1/100 second.
Lap/Split Measurement
While the stopwatch is running, press the LAP/SPLIT button to record lap times or split times. The display will momentarily show the recorded time before returning to the running total. The device can store up to 300 individual lap/split records.
Memory Recall Function
To review stored lap and split times, activate the Memory Recall function. This is typically done by pressing a dedicated MEMORY or MODE button. You can then scroll through up to 300 recorded entries. This function can often be accessed even during an ongoing measurement without interrupting the current timing.
Power Saving Function
The stopwatch is equipped with a power-saving mode to conserve battery life when not in active use or exposed to light. This function activates automatically after a period of inactivity or darkness. To reactivate the display, expose the stopwatch to light or press any button.
Sound Off Function
The operation confirmation sound can be disabled if desired. Refer to the device settings or the full manufacturer's manual for instructions on how to activate or deactivate this feature. This is useful in environments where audible feedback is not preferred.
Maintenance
Charging
Regularly expose the stopwatch to light to maintain its charge. Avoid prolonged storage in dark environments to prevent battery depletion. Even indirect light exposure during daily use is often sufficient to keep the device charged.
Water Resistance
The stopwatch has a water resistance rating of 5 ATM. This means it is resistant to splashes, rain, and brief immersion in water, such as during hand washing. It is not suitable for swimming, diving, showering, or any activities involving high-pressure water exposure.
Cleaning
Clean the stopwatch with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the case, display, or internal components.
Troubleshooting
Display is blank or dim
- Solution: Ensure the stopwatch has been sufficiently exposed to light for charging. Place it under bright light for several hours. If the issue persists, the power-saving function might be active, or the battery may require extended charging.
Incorrect Time/Date
- Solution: Verify the auto-calendar function is operating correctly. If manual adjustment is needed, refer to the full manufacturer's manual for detailed steps on how to set the time and date.
Buttons are unresponsive
- Solution: Check for any debris or foreign objects obstructing the buttons. If the issue continues, a soft reset (if available for your model) might be necessary. If problems persist, contact customer support.
