When the watch is in a horizontal position, align it so the needle points to 0, and the 12 o'clock direction points north.

In compass measurement mode, press Button D [Compass] to turn the inverted direction display on/off. When the inverted direction is open, "-" appears in the bottom left of the display. When the needle points to 0, the "S" direction, marked at the 12 o'clock position, represents South.

If no button is pressed for 1 minute, the measurement mode will exit. Pressing Button D [Compass] can restart the measurement.

Compass Direction Table:

Note: If you have never used this compass before, calibrate it according to the following procedure.

Compass Setting Mode:

Automatic Calibration Mode (CAL): In compass mode, press and hold Button B [Mode/Set] for 2 seconds to enter CAL. Press E [Baro/Alti] or C [Alti] and slowly rotate the watch clockwise or counter-clockwise. The watch will automatically exit adjustment mode and return to compass measurement mode by turning the two wheels in the same direction. During calibration, when 60 directional points light up and then turn off one by one, the correction is automatically confirmed. (Note: The compass enters automatic setting mode after battery replacement and first use.)

Digital Adjustment Mode (DEC): If you have the correct north but still experience deviations, use DEC for adjustment. To enter CAL, press and hold Button B [Mode/Set] for 2 seconds in compass mode, then press Button B [Mode/Set] again to enter DEC (pressing E [Baro/Alti] increases the value by 1, pressing C [Alti] decreases it by 1). The maximum correction angle range is ±90° ("W" "E" °C). Press and hold Button B [Mode/Set] for 2 seconds to confirm the adjusted value and return to normal measurement mode.

Note: You do not need to press the 2 items listed below.

Sensor Check Explanations (Vysvetlivky na kontrolu senzorov)

• If a sensor error exists between the MCU and the sensor, an error will be displayed.
• Error codes: "ERR1" (Pedometer IC and MCU), "ERR2" (Compass IC and MCU), "ERR3" (Temperature sensor and MCU).
• The above errors are displayed for 2 seconds and will not reappear upon re-entering time setting mode.
• If everything is normal, no error will be displayed, and the system will proceed directly to time measurement mode.

General Explanations (Univerzálne vysvetlivky)

1. Altitude Measurement: Measures altitude every 15 minutes. If the trend graph in altitude mode shows a change of less than 8 meters, it will follow sea level changes, not actual altitude. In this case, it determines pressure based on the previous 15 minutes. If the change is more than 8 meters, the system detects ascent, and the pressure remains the same.
2. Measurement Intervals: For the first 5 minutes after entering altitude or pressure measurement mode, or exiting setting mode, it measures every 2 seconds. After 5 minutes, it measures every 2 minutes. Other modes last for 15 minutes.
3. Magnetic Declination Setting: If set to "+", the actual declination including adjustment is displayed. If set to "-", only the actual declination without adjustment is displayed.
4. Weather Forecast: Updated hourly (predicts weather based on air pressure distribution over the previous 4 hours). If air pressure gradually increases, the weather is expected to improve. If air pressure gradually decreases, the weather is expected to worsen.

There are 4 types of weather conditions (from good to bad): Sunny, Cloudy, Overcast, Rainy.

Measurement Parameters (Meranie veličín)

a) Pressure Detection: Every 59 minutes 59 seconds.

b) Pressure Calculation: Pressure from the previous hour minus the current hour, total 4 values. If the absolute value is greater than 2.5 mbar, it is disregarded. Use valid values for averaging. Weather is determined by the average value.

• Sunny: 0.8~2.5 (mbar/h)
• Cloudy: 0.5~0.8 (mbar/h)
• No change: -0.5~0.5 (mbar/h)
• Overcast: -1.0~-0.5 (mbar/h)
• Rainy: -25,~-1.0 (mbar/h)

Notes:

Temperature measurement is affected by direct sunlight and humidity. To ensure accurate temperature readings, remove the watch from your wrist and place it in a location not directly exposed to sun or ventilation. Dry the watch case. Drying the watch case so it reaches ambient temperature takes approximately 20 to 30 minutes.
