2. OPERATION CHART: MODULE QW-2634
Getting Acquainted
Congratulations upon your selection of this CASIO watch. To get the most out of your
purchase, be sure to carefully read this manual and keep it on hand for later reference
when necessary.
Expose the watch to bright light to charge its battery before using it.
You can use this watch even as its battery is being charged by exposure to bright
light.
Be sure to read “Battery” of this manual for important information you
need to know when exposing the watch to bright light.
If the digital display of the watch is blank...
If the SLEEP indicator is on the display (either flashing or
steady), it means that the display is blank because the
watch’s Power Saving function has turned off the display
to conserve power.
Power Saving automatically turns off the display and
enters a sleep state whenever the watch is left for a
certain period where it is dark.
The initial factory default setting is Power Saving on.
The watch recovers from the sleep state if you move it to
a well-lit area
*
, if you press any button, or if you angle
the watch towards your face for reading.
*
It can take up to two seconds for the display to turn
on.
See “Power Saving Function” for more information.

Setting the Time and Date
When setting the time, you can also configure settings for the display illumination
duration, the 12/24-hour format, power saving on/off, and the Dual Time screen.
About the Dual Time screen
The Dual Time screen is initially set up to show the time in Kona, Hawaii, which is the
site of the Ironman Triathlon. You can leave this setting the way it is or change it to
show the current time in another time zone.
If you need to adjust the current Kona time setting, use the “Time Differential Table”
for reference. If you live in Tokyo for example, you would need to subtract 19 hours
from the current Tokyo time to determine the current time in Kona, Hawaii. Note that
the times in the “Time Differential Table” are standard times. You need to subtract
one hour from these times during periods when summer time (Daylight Saving Time)
applies.
You can also use the Dual Time screen to keep track of the current time in another
area outside of the Kona, Hawaii time zone. If you do, you should turn off
(Kona time zone indicator) on the Dual Time screen. This will cause the indicator to
be replaced by an indicator that shows the day of the week for the current date.
To set the time and date
1. In the Timekeeping Mode, hold down
until the
seconds start to flash, which indicates the setting
screen.
2. Press
to move the flashing in the sequence shown
below to select other settings.
3. When the setting you want to change is flashing, use
