[. . . ] Its Auto Backlight function automatically lights the watch face whenever you turn your wrist towards your face. · In order to protect against running down the battery, the auto backlight function is automatically turned off approximately three hours after you turn it on. Repeat the above procedure to turn the auto backlight function back on if you want. · Pressing E in any mode illuminates the display for about two seconds, regardless of the auto backlight function on/off setting. About the Auto Backlight function While the Auto Backlight function is turned on, the backlight automatically lights for about two seconds in any mode whenever you position your wrist as described below. C E D Notes · The backlight of the watch employs an electroluminescent (EL) light, which loses illuminating power after very long use. · Frequent use of the backlight shortens the battery life. [. . . ] Press D to increase the current reference altitude value by 5 m or B to decrease it. Holding down either button changes the value at high speed. · You can set the reference altitude within the range of ­4000 m to 4000 m. · Pressing B and D at the same time returns to the "OFF" message. After setting the reference altitude you want, press A to return to the Altimeter Mode. Auto memory indicator *2 m Altitude alarm *3 Current altitude Current time C About the Altitude Alarm The altitude alarm sounds for about five seconds whenever the current altitude matches a preset value. You can press any button to stop the alarm after it starts to sound. A S P A S ALTI ALTI C E D Current temperature Example If you set the altitude alarm at 130 meters, it sounds when you pass the 130-meter mark on your way up and on your way back down. Mode indicator *1 *1 "ALTI" flashes while a measurement is being taken every five seconds. It does not flash during measurements taken every two minutes. while a memory measurement is in *2 "AUTO" flashes on the displayflashing while no measurement is being progress. The indicator stops *3 " performed. AL " appears on the display when the altitude alarm is switched on. To set the altitude alarm 1. In the Altimeter Mode, hold down A until the display clears. · If the altitude alarm is on, the altitude alarm indicator remains on the display when you change to another mode. A S ALTI --6-- About the graphic display In the Altimeter Mode, the graphic display normally indicates the counting of the current time's seconds. When a memory measurement operation is being performed while the altitude alarm is on, however, the watch automatically divides the graphic display into 10 equal parts. Each part represents 1/10 of the difference between the first altitude measured by the memory measurement operation and the value you set as the altitude alarm. The graphic representation gives you some idea of how much farther you must go to reach the altitude indicated by the altitude alarm setting. · The graphic representation described below is not shown on the display if the altitude alarm is switched off. Important! You cannot delete data while a memory measurement is in progress ("AUTO" flashing on the display). A AUTO B m C 1. In the Recall Mode, display the initial data of the set of memory data you want to delete. · Display the maximum altitude or the minimum altitude if you want to delete it. To clear the data, hold down A until the watch emits a long beep (and until "CLR" stops flashing on the display). A S RECALL Example: When the initially measured altitude is less than the altitude alarm setting. Altitude alarm setting C E D Current altitude The graphic display would appear as illustrated here when your current altitude is 700 meters, after you set the altitude alarm for 1000 meters and the initial measurement was 0 meters. Note that seven segments of the graph are darkened because you are 7/10 of the way to the value set for the altitude alarm. BAROMETER FUNCTIONS This watch uses a pressure sensor to measure atmospheric pressure. This sensor can be calibrated. Important! The barometer that is built into this watch measures changes in atmospheric pressure, which you can then apply to your own weather predictions. It is not intended for use as a precision instrument in official weather prediction or reporting applications. · Segments in the graphic display darken as you approach the altitude alarm setting. [. . . ] Press D to increase the selected digits and B to decrease them. Holding down either button changes the selection at high speed. · The format (12-hour or 24-hour) of the alarm time matches the format you selected for normal timekeeping. · When setting the alarm time using the 12-hour format, take care to set the time correctly as morning (no indicator) or afternoon (P).
