Answer: The face of this watch is marked with values that increase in a counterclockwise direction. These values represent degrees. When you take a direction reading, you can use these values to find out how many degrees the 12 o�clock position of this watch (which is the direction indicated in the digital display) differs from magnetic north. For example, when the Magnetic North Indicator is pointing at �90� on the watch�s face, it means that the 12 o�clock position is 90 degrees from magnetic north (which means that 12 o�clock is pointing due east).

Question: How does the barometer work?
Answer: Barometric pressure indicates changes in the atmosphere, and by monitoring these changes you can predict the weather with reasonable accuracy. Rising atmospheric pressure indicates good weather, while falling pressure indicates deterioration weather conditions. The atmospheric pressure that you see in the newspaper and on the TV weather report are measurements corrected to values measured at 0 m sea level.

Question: What should I do if I lose track of which mode I am in or lose my way when making settings?
Answer: Hold down the C button for two or three seconds to return to the Timekeeping Mode. Next, try performing the operation you want again.
