[. . . ] You remove the offset by adjusting the altitude. Adjust the altitude when you want precise altitude readings, such as before hiking or climbing, or when you want to update the Sea Level Barometer. Adjust at a known altitude such as at the sea side, a marked summit or pass, or a location with an altitude reference on a map such as a lake. Home or office make convenient adjustment points after learning their elevations from a topographic map. Adjust once a day when hiking, climbing, or when following weather patterns. You can also adjust altitude in the barometer by entering a current, local barometer reading from a weather report or airport weather service. When you enter the barometer reading, the altitude is also adjusted in the altimeter. Note: The analog and digital movements of this watch operate indenpendantly. Please set each individually to ensure they are kept in sync. 17 ALTIMETER AND BAROMETER DETAILS Effects of Atmospheric Pressure Changes. A change in atmospheric pressure will make the displayed altitude different from the known altitude of a landmark. The ST 4000 can be adjusted so that it displays the same altitude as the landmark. Minor atmospheric pressure changes may cause the displayed altitude to vary from the actual altitude by 50 feet. With the arrival or departure of a weather front, displayed altitude can change 100 to 200 feet, and a storm can cause a change of more than 200 feet. Wind, rain, snow, and humidity do not affect altimeter readings. Synchronization (the relation between altitude and sea level barometer) is set at the factory. To ensure barometer accuracy you can check it after a year or two and correct minor drift if necessary. You must know your current altitude and must get the current sea level barometer from a local airport or weather broadcast to make this adjustment. You can also synchronize the thermometer if it reads consistently high or low over a range of temperatures. Thermometer Accuracy. The ST 4000 measures the ambient air temperature with a sensor inside its case. When the watch is worn against your skin, temperature readings will be affected significantly. Direct sunlight can also cause the ST 4000 to give high readings. For accurate readings, remove the watch from your wrist and place away from direct sunlight. [. . . ] The arrow at the left of the display blinks when the accumulator is on. Remember to turn the accumulators on before beginning your activity and off when you finish; otherwise you will record no vertical feet or will record unwanted vertical feet. Both accumulators record up to 500, 000 vertical feet with 5 feet resolution. The ST 4000 accumulates vertical feet ascended and descended. [. . . ]
