1.0 Introduction

Thank you for purchasing this model. Your Watch includes 5 functional modes. They are the Current Time Mode, UV Index Mode, Daily Alarm Mode, Chronograph Mode and Timer Mode.

This Watch equipped with an UV sensor that measures UV radiation in terms of UV index. This model also includes 2 UV index alarms. In addition to the UV sensing, this model also included current time, daily alarm, chronograph and timer functions.

Your Watch is carefully designed and produced, in order to utilize this feature of your Watch, it is advisable to use the Watch in conformity with the below notes:

! Read this manual before using the Watch.

! Avoid exposing your Watch to extreme

conditions for an unreasonable time.

! Avoid rough use or severe impacts to your

Watch.

! Store your Watch in a dry place when it is

not in use.

! It is recommended to have the battery

replacement done by a certified service agency as this practice will maintain the water resistance standard on your Watch.

! Clean your Watch occasionally with a soft

moistened cloth. DO NOT expose the Watch to strong chemicals such as gasoline and alcohol, as they will damage your Watch.

! DO NOT use this Watch for commercial or

professional purpose.

! Make sure that you fully understand the

functions and limitations of this Watch before using it.

! Always compare the UV reading with the

one broadcasted by local weather station.

! Excessive exposure to UV radiation could

cause fatal harm to a human body, always follow the 'Basic Sun Protection Messages' by the World Health Organization when you go out in the Sun.

5.3 UV Index Mode - How UV is Sensing

! This Watch uses a built-in UV sensor to detect

ambient Ultraviolet radiation which is then converted to UV Index.

! The UV Sensor is the small spot that is located

on the lower part of the dial. Check the previous

'2.0 Parts and Its Functions' Section for the

detail on the location of the UV Sensor.

Notes to UV Measurement

! To make an accurate result, employ the

following steps when taking a UV measurement:

1) Position the UV Sensor directly to the source of radiation, for example the Sun.

2) Avoid sheltering the UV Sensor unintentionally.

3) Rotate the Watch slowly and search for the maximum reading.

4) Clean the lens of the Watch with a soft cloth before the measurement, this practice allows NO dirt or dust sheltering the UV sensor.

! During the first five minutes of UV Index Mode, the

Watch needs two seconds to get a reading.

! After the first five minutes of UV Index Mode, the

Watch needs 10 seconds to get a reading.

UV Index Bar Segment

! To provide user a quick concept about the Current

and Peak UV Indexes, this Watch exhibits them by displaying a different number of bar segments on the upper row of the display.

! Whether the Current or Peak UV Index Bar

Segment appear on the upper row of the display, one exhibited bar segment equals one UV Index. For example, if there are 5 bar segments displayed on the upper row of the display, the UV Index is 5.

UV Index Color Code

! As categorized by the World Health Organization,

each UV index is matched with a color code. Check the previous '5.1 UV Index Range, Exposure Category and Color Code' Section for more detail on the Color Code.

! To provide user a quick concept about the color

code of the current and peak UV index, this Watch also printed green, yellow, red (stand for orange and red) and purple color on the display.

Read the color code of a UV index by checking the color background of the right-most exhibited UV index bar segment. For example, if there are 5 bar segments displayed on the upper row of the display, the color code is Yellow.

in the factory. The most possible cause

for deviation is the Ozone thickness, difference between the place of use and cali-

bration of the Watch. For normal usage, you

should not need to calibrate the Watch again.

! DO NOT attempt to calibrate the UV index unless

you have the following items to determine the Calibration Factor (CAL):

1) Standard UV generator or

2) Correct immediate local UV Index DO NOT use the UV Index broadcasted by the

local weather station as the correct UV index, it may NOT the correct one at your place when you calibrating your Watch, this is because:

1) Weather stations usually broadcast the 15minute mean UV Index to public. It is different from the instantaneous UV radiation that your Watch is now sensing.

2) Cloud condition affects UV Index. Hence, the UV Index at your location may not be

identical to the one at weather station if the two cloud conditions are not alike.

Check the coming '5.9 To Determine the

Calibration Factor (CAL)' Sections for more detail

on how to determine CAL.

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)

! Determine the CAL by using the following rules:

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

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. CAL= 25 + ADJ.

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; ! CAL= 25 + ADJ; ! Hence, CAL=25 -17 = 8.

Example 2: To adjust the UV Index from 7.8 (Exhibited UV index) to 8.0 (Correct UV Index).

! ADJ = ((8.0 - 7.8) / 7.8) X 100 = 3; ! CAL= 25 + ADJ; ! Hence, CAL=25 +3 = 28.

To resume the Watch to its original setting for sensing UV radiation, select the default value (25) as the CAL during the calibration.

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
