Press and hold the button to exit setting sequence. [start/stop] Button l In Current Time Mode: Press the button to select between the Date Display and UV Index Display l In Daily Alarm Mode: Press the button to select between ON and OFF the daily alarm l In Chronograph Mode and Timer Mode: Press the button to start/stop the counting l In setting displays: Press the button to scroll through the setting. [. . . ] When the 'HI' indicator appear: Press the [start/stop] or [lap/reset] button to select the Upper UV Index Alarm setting among 0 to 25 (select ' -- ' to turn OFF the alarm) by scrolling of 1 (hold down the button to scroll the setting faster). Note: To control the UV exposure by a two-level alarm, set a smaller value (for example: 6) for the Lower UV Index Alarm, and set a larger value (for example: 10) for the Upper Index Alarm. When the above settings finished, either press and hold the [mode] button for about 2 seconds to exit the setting sequence or press the [mode] button once to calibrate the UV Index. To calibrate the UV Index, check the coming '5. 8 Precautions to UV Index Calibration', '5. 9 To Determine the Calibration Factor (CAL)' and '5. 10 Calibrating the UV Index' Sections for more detail on the UV Index Calibration. 5. 9 UV Index Mode - To Determine the Calibration Factor (CAL) Standard UV Generator (Correct UV Index) Ultraviolet Radiation UV Sensor Exhibited UV Index the Watch How Exhibited UV Index is obtained for determent of CAL scroll the setting by increment of 1 [start/stop] scroll the setting faster hold [start/stop] UV Index Mode (Current UV Index Display) [mode] hold hold [mode] [mode] 'HI' Upper 'LO' Lower UV Index UV Index Alarm Alarm [mode] [mode] 'CAL' Calibration UV Index Mode Setting Sequence [lap/reset] scroll the setting by decrement of 1 hold [lap/reset] scroll the setting faster !Determine the CAL by using the following rules: 1)Correct UV Index: The UV index produced by a standard UV generator or other similar means. 2)Exhibited UV Index: The UV Index exhibited by the Watch when it is exposed to the previous standard UV generator. 3)ADJ: The percentage change of UV Index. Hence ADJ = ((Correct UV Index - Exhibited UV index) / Exhibited UV index) X 100% 4)Calibration Factor (CAL): The value that to be selected for the calibration. Example 1: To adjust the UV Index from 4. 8 (Exhibited UV index) to 4. 0 (Correct UV Index). ADJ = ((4. 0 - 4. 8) / 4. 8) X 100 = -17; !Example 2: To adjust the UV Index from 7. 8 (Exhibited UV index) to 8. 0 (Correct UV Index). To resume the Watch to its original setting for sensing UV radiation, select the default value (25) as the CAL during the calibration. 14 16 5. 10 UV Index Mode - Calibrating the UV Index To Calibrate the UV Index !When the settings of the previous '5. 7 Setting the Upper and Lower UV Index Alarms' Section are finished, press the [mode] button once to calibrate the UV Index. When the 'CAL' indicator appears, press the [start/stop] or [lap/reset] button to select the predetermined CAL between 0 to 50 by scrolling of 1 (hold down the button to scroll the setting faster). Check the previous '5. 9 To Determine the Calibration Factor (CAL)' for more detail on how to determine the CAL. When the above settings finished, press and hold the [mode] button for about 2 seconds to exit the setting sequence. The setting display will change to UV Index Mode automatically if no key-stoke has been activated for about 3 minutes. 6. 1 Daily Alarm Mode - Setting the Daily Alarm Mode !To set the Daily Alarm Time, press and hold the [mode] button to select the setting display. When the 'minute' digits flash on the display, press the [start/stop] or [lap/reset] button to set the minute by scrolling of 1 (hold down the button to scroll the setting faster). When the 'hour' digits flash on the display, press the [start/stop] or [lap/reset] button to set the hour by scrolling of 1 (hold down the button to scroll the setting faster). When the setting is finished, press and hold the [mode] button to exit the setting sequence. The setting display will change to Daily Alarm Mode automatically if no key-stoke has been activated for about 3 minutes.
