When stop-counting, pres s

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.

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:

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.

! 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.

The UV Index is a measure of the solar UV

(ultraviolet) intensity at the Earth's surface

relevant to the effect on human skin.

The skin-damaging UV radiation is governed by

the erythemal action spectrum, the black line in

the adjacent figure.

This spectrum has been adopted by the

International Commission on Illumination (CIE) to

represent the average skin response over the

solar UV spectrum.

! 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. 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
