FAQs

How do I set the time and date?

Refer to the user manual for detailed instructions. Usually, you'll need to enter the setup mode and adjust the settings.

How accurate is the altimeter?

The altimeter provides reasonably accurate readings but requires regular calibration against a known altitude. Changes in barometric pressure can also affect the readings.

How often should I calibrate the compass?

Calibrate the compass regularly, especially before important activities. Check the compass reading against a known direction to confirm its accuracy.

What does the barometer measure?

The barometer measures atmospheric pressure, which can be used to predict weather changes. Falling pressure usually indicates approaching storms.

Is the watch waterproof?

The watch is water-resistant up to 100 meters (10 ATM). However, avoid pressing buttons underwater.

How long does the solar battery last?

The solar battery provides power for several months with a full charge, depending on usage and light exposure.

Can I replace the watch band?

Yes, the watch band is replaceable. You can find replacement bands online or at watch repair shops.

What kind of warranty does it have?

The watch comes with a 2-year warranty.

Troubleshooting

Watch is not displaying correct time.

Check the time zone setting and sync the watch with a reliable time source. Reset the watch.

Altimeter readings are inaccurate.

Calibrate the altimeter using a known altitude reference point. Ensure there are no rapid changes in atmospheric pressure.

Compass readings are inconsistent.

Calibrate the compass away from magnetic interference (e.g., electronic devices, metal objects). Ensure the watch is level during calibration and use.

Barometer readings are fluctuating rapidly.

Ensure the watch is not exposed to sudden changes in temperature or pressure. Check the weather forecast for accuracy.

The watch is not charging.

Ensure the watch is exposed to direct sunlight. The solar panel needs sufficient light to charge. Check the battery level indicator.
