! 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 shelter ing 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.
! The UV Index Mode includes two functional
displays. They are the Current UV Index Display
and Peak UV Index Display.
Current UV Index Display
! The Current UV Index Bar Segment displays on
the upper row of the display. The Cu rr en t UV
Index and UV Index Alarm Indicator
display on the
lower row of the display.
Note: When this display has been selected, and
then the watch returns to Current Time Mode: the
Current UV Index Bar Segment and Current UV
Index will
display if UV Index Display is selected.
Peak UV Index Display
! The Peak UV Index Bar Segment appears on the
upper row of the display. The Peak UV Index and
the UV Index Alarm Indicator appear on the lower
row of the display.
Note: When this display has been selected, and
then the watch returns to Current Time Mode: the
Peak UV Index Bar Segment and Peak UV Index
will
display if UV Index Display is selected.
To Select between the Current and Peak UV
Index Display
! Press the [start/stop] button once to select
between the Current UV Index Display and Peak
UV Index Display.
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 equal s 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
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.
! 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.
