• Note: After changing the battery or using the compass for the first time, it will automatically enter this adjustment mode.

Digital Adjust Mode (DEC):

• If your compass shows a correct north but still deviates significantly, use the DEC mode for correction.

Note: You do not need to print the following two items (Universal Explain).

Universal Explanation

1. The curve displayed in Atmospheric Pressure mode is not the actual altitude. It detects altitude every 15 minutes. If the altitude change is not more than 8 meters, it is attributed to sea level change, not actual altitude. In this case, the pressure value is calculated based on the altitude from the previous 15 minutes. If the change exceeds 8 meters, it assumes you are climbing, and the pressure reading remains constant.
2. Measurement Frequency: For the first 5 minutes after entering Altitude or Pressure measurement mode, or after exiting setting mode, measurements are taken every 2 seconds. After 5 minutes, measurements are taken every 2 minutes. In other modes, measurements are taken every 15 minutes.
3. Magnetic Declination: If '+' is set, the displayed value is the actual declination plus the adjusted value. If '-' is set, it is the actual declination minus the adjusted value.
4. Weather Estimation: The watch estimates the weather hourly by analyzing air pressure changes over the previous 4 hours. A gradual increase in air pressure suggests improving weather, while a gradual decrease indicates deteriorating weather. The four weather status categories (from good to bad) are: Sunshine, Cloudy, Overcast sky, Rainy.

Method for Weather Estimation:

• Detect the pressure every 59 minutes and 59 seconds.
• Calculate the difference between the pressure from 1 hour ago and the current hour (using 4 values). If the absolute difference is more than 2.5 mbar, that value is considered invalid. The average of the valid values is used to judge the weather.

Weather Conditions and Pressure Changes:

• Sunshine: 0.8~2.5 (mbar/h)
• Cloudy: 0.5~0.8 (mbar/h)
• No change: -0.5~0.5 (mbar/h)
• Overcast sky: -1.0~ -0.5 (mbar/h)
• Rainy: -2.5~ -1.0 (mbar/h)

Notes on Temperature Measurement: Temperature readings can be affected by personal body temperature, direct sunlight, and humidity. For more accurate measurements, remove the watch from your wrist and place it in a location not directly exposed to the sun, with good ventilation and a dry case. Allow approximately 20 to 30 minutes for the watchcase to reach the ambient temperature.

2. Detect the direction 1 time each minute.
3. Atmospheric Pressure or Altitude Measurement: At the first 2s, it measures 1 time. 5 minutes later, it measures every second. At 15 minutes later, it measures every 2 minutes.
4. Other Modes: Measurements are taken every 15 minutes.
